 Pre-installation Before you begin installing your Libra MAX-58 base station and subscriber stations, you need to take certain issues and conditions into consideration, prior to, and throughout, the entire installation process. This chapter defines some of the more common installation concerns. Start by reviewing the equipment packing lists to ensure that you have all the cables, connectors, surge protection devices, fasteners, antennas, and any other installation material you will require to properly install your equipment. You should also visually check all components for any physical damage. Throughout this guide, the term “ODU” refers to the Base Station “Out Door Unit” portion of the Libra MAX-58 system, this includes the Libra MAX-RBS and the radio portion of the Libra MAX-HD. If possible, you should connect all necessary cables and power up the radio equipment to confirm that it has not been damaged during shipping. You can also perform the units’ initial configuration before they are sent out to the field. This will ensure your equipment and all interconnecting cables are functioning properly. Refer to chapters 4 and 5 for more information on configuring your Libra MAX-58 equipment for the first time. EION provides this document as a general set of guidelines for installing its Libra MAX-58 equipment. In no way does EION provide any warranties as to the effectiveness of these guidelines. Implementation of these guidelines is solely at your discretion. You must ensure that the equipment is installed and grounded in accordance with the local electrical and building codes and the codes of the country of operation. The Libra MAX-58 equipment must be installed by a certified professional communication installer, familiar with all necessary local regulations. 1.6 Required Tools Before you go on-site or out into the field to install your equipment, make certain you have all the necessary tools to perform the installation properly. The following list of tools is a general guideline of the tools you may need. Some installations may require more specialized tools, while others may only need a few of the tools listed here. Each specific installation will dictate your tool requirements. Basic Hand Tools • socket set • crescent wrench • cable cutters • pliers • a variety of screwdriver types and sizes Power Tools Libra MAX User Guide  Pre-installation: Required Tools  Page 14 of 120
 • electric drill • drill bits of assorted sizes and lengths • hole saw Specialized Tools • Crimp tools for: • Ethernet connectors • RF connectors • power and grounding compression lugs • Laptop or PDA Test Equipment • spectrum analyzer to check for interference • site master to check the antennas for proper VSWR Consumables • butyl rubber tape or pads • anti-oxidizing paste • low temperature tape Miscellaneous • ladders • compass • GPS • binoculars Cables • DB9 serial cable (male to female) for the base station • EION proprietary serial cable for the subscriber station • Ethernet crossover cable 1.7 Site Evaluation Before you begin the actual installation of you Libra MAX-58 equipment, you need to make certain that your equipment site is acceptable and has been properly prepared. Site preparation will depend on whether you will be installing the MAX-HD chassis base station, MAX-LT ODU, MAX-RBS ODU or a MAX-SS subscriber station. Libra MAX User Guide  Pre-installation: Site Evaluation  Page 15 of 120
 1.8 Base Station Site Considerations When you are preparing your site for your Libra MAX-58 base station, you will need to make allowances for both the base station’s Indoor Unit (IDU) and one or more Outdoor Units (ODU). 1.8.1 Indoor Unit Site Considerations Your first step should be to review your network plan and make certain that the chosen site will be able to house all of your network equipment, not just your Libra MAX-58 system. During your site examination, make certain that you have left adequate service access in both front and back of any cabinets or equipment racks you are installing. The site environment for your base station’s IDU should be clean, dust-free, and if possible, climate controlled. If a climate controlled environment is not possible, you need to make certain that the equipment can be operated within its specified environmental limits. Ensuring that there is enough room around your cabinets and racks for proper ventilation will aid in proper operation of the units. Proximity to the units’ power mains and correct cable length are other issues that need to be considered when selecting and preparing your equipment site. The physical location of the base station’s IDU in the site should be as close as possible to the AC or DC mains in order to minimize cable length. This connection should be made with appropriate sized cables. The following table provides the appropriate cable lengths for a DC power source. DC Power Cable Size - 10 amps 5% voltage drop Maximum Cable length between the equipment and DC distribution (feet/meters) 14 AWG 22.97/7 12 AWG 0 10 AWG 0 The site must also include a properly installed principle ground bar (PGB) that the equipment cabinet or rack will be connected to. The physical location of your IDU should also be influenced by its location to the base station’s ODU. It is important that you locate the IDU as close to where the ODU will be mounted to minimize cable lengths. 1.8.2 Outdoor Unit Site Considerations Conversely, when making your decisions about the ODU’s mounting location, you need to consider issues such as its proximity to the base station’s IDU if needed, cable lengths between the IDU and the ODU, and so on. You should first inspect the site to verify that the antenna mounting structure is suitable for both the antenna and ODU. The ODU needs to be positioned in a location that allows for easy maintenance access. You also must review routes that the cables will follow, when connecting the IDU to the ODU. Libra MAX User Guide  Pre-installation: Base Station Site Considerations  Page 16 of 120
 You should review the proposed cabling entrance/exit points for the site’s building; they must be practical. You must be able to easily drill the holes for cable access and the cables should be in a location that allows for easy maintenance. The MAX ODU has a single shielded CAT5/5e cable to connect the ODU to the IDU sector card or to connect the ODU to the POE inserter. It is important not to exceed the maximum allowed length of 100 meters for this cable. This Ethernet cable provides power to the ODU. 1.8.3 Subscriber Station Site Considerations Preparing the site for your Libra MAX-58 subscriber station or stations is similar to the site preparation for the base station’s ODU. You should first inspect the proposed site to verify that the line-of-site and Fresnel Zone clearances can be met. You also need to verify that the unit mounting structure is suitable for both the subscriber station, and the subscriber station’s antenna, if a separate antenna is used. The subscriber station needs to be positioned in a location that allows for easy maintenance access. If the subscriber station is to be mounted to a wall, you will need to consider how the wall’s material will affect your mounting strategies; the wall is made of cinder-block, wood, concrete, and so on. You will then need to acquire the appropriate mounting fasteners to fit the wall material. You must also review routes that the cables will follow, when connecting the subscriber station to your terminal equipment. Review the proposed cabling entrance/exit points for the site’s building; they must be practical. You must be able to easily drill the holes for cable access and the cables should be in a location that allows for easy maintenance. The subscriber station’s proximity to your terminal equipment must be considered as this will affect the cable lengths between your terminal equipment and the subscriber station unit. Cables must always be connected without exceeding their recommended bend radius. 1.9 Base Station Power Sources If your equipment uses AC power, make certain that the power is provided from a separate, isolated circuit and that you are using a surge protected power source or a dedicated Uninterruptible Power Supply (UPS). This will aid in protecting your equipment against power surges, spikes and/or possible lightning damage. Providing clean, filtered power will also minimize the possibility of system performance degradation due to RF interference. If your base station equipment uses DC power, your power should be supplied from the main station DC power panel, through a dedicated fused output. A fuse of 15 Amps should be used. Libra MAX User Guide  Pre-installation: Base Station Power Sources  Page 17 of 120
 1.10 Grounding Grounding your equipment properly is one of the most important operations you will perform during installation. Equipment grounding is required for both safety and effective operation of the installed lightning protection devices. You must ensure that your system is grounded in accordance with your local electrical codes and safety laws. EION does not provide any warranties as to the effectiveness of the grounding concepts and processes described here, they are for your reference only. EION is not liable for any damage to your equipment or any injuries to you resulting from improper grounding. 1.10.1 ESD Warning Before you begin to install your base station and its components, you should ensure that your equipment will be protected against electrostatic discharge (ESD). This section lists some guidelines that you should take into account during installation. • Proper grounding is extremely important. Make certain that you ground yourself before you begin working with your equipment. Also try to ensure that your workspace is static-free and make use of an anti-static wrist or leg straps. If you do not have access to static protection, ground yourself to your environment by first touching your finger to a metal surface before touching your equipment. • All electrical components should be moved or stored in an anti-static bag. Before you remove a component from its anti-static bag, you should first hold the bag in one hand while touching a metal surface with the other hand, then perform the same action with the component. • Handle electronic components as little as possible and when you do handle them, hold all parts by their edge. • Never slide static-sensitive equipment across any type of surface. Friction can cause static build-up. • Keep any non-conductive material, such as Styrofoam and other plastics, away from your work area 1.10.2 Outdoor Unit Grounding When you are installing your outdoor units, you need to follow proper grounding practices. The proper grounding of outdoor units helps to minimize lightning damage and dissipate static buildup. In general, grounding is accomplished by installing a single heavy gauge wire, such as a 6 gauge, copper cable, between the outdoor unit’s grounding lug and the mounting structure’s grounding point. The following section sets out some grounding guidelines for you to follow during installation. • It is very important that the grounding system for your outdoor equipment be installed by a fully qualified, professional installer, and that proper safety practices are followed in accordance with your local electrical code. Libra MAX User Guide  Pre-installation: Grounding  Page 18 of 120
 • Locate your grounding point as close to the outdoor unit as possible. It must be below the unit and must not be inside a building. • The grounding point can be located on an unpainted section of a metal tower, as section of a building’s metal structure or a ground riser per your applicable local electrical code. • When you run the ground cable to the grounding point, make certain that it follows a direct path and that you avoid sharp bends in the cable. • Do not drill holes in tower supports or cross braces to provide a grounding point. • Do not remove any paint on the outdoor unit chassis. • Do not secure the ground cable in a bundle with other data, power, or RF cables. • The chassis of the outdoor unit’s power supply must be connected to the frame or cabinet via a ground strap. If you are installing more than one outdoor unit and they will be in close proximity to each other, do not daisy chain the units’ grounds to each other. This means that you should not connect the ground of one unit to the ground of another unit and finally to the grounding system, as shown in Figure 0-1 Daisy Chain Configuration.  Figure 0-1 Daisy Chain Configuration Daisy chaining the grounds of your units will cause problems such as ground loops, high resistance paths between units, and reduced ability for dealing with lightning. Instead, you should use a star configuration, as shown in Figure 0-2 Star Configuration. In this configuration, each outdoor unit’s grounding lug is connected to a common grounding point that is then connected to the earth ground. Libra MAX User Guide  Pre-installation: Grounding  Page 19 of 120
  Figure 0-2 Star Configuration 1.10.3 Indoor Unit Chassis Ground  The base station’s indoor unit shelf should be grounded to the cabinet or rack through a grounding strap. This strap needs to be connected from the grounding bolt, located at the back of the chassis, to the cabinet’s (or rack’s) grounding bar. It is not sufficient to rely on the mounting screws to ground the chassis to the cabinet. You must also run the cable to the grounding point in a direct path and avoid sharp bends. Do not secure the ground cable in a bundle with other data, power, or radio frequency cables. 1.11 Lightning Protectors The use of lightning protectors and surge suppressors is extremely important and, although your Libra MAX-58 equipment will operate without them, it is highly recommended that you make use of them. Lightning protectors and surge suppressors are used to aid in the protection of your outdoor units against lightning damage and static discharge. During installation, it is important to note that all lightning protection devices have a surge (or cable-facing) side and an equipment facing side, as shown in Figure 0-3 Surge Suppressor Sides. The equipment side generally faces the outdoor unit or the indoor power adapter. The surge side faces the other surge suppressor. Libra MAX User Guide  Pre-installation: Lightning Protectors  Page 20 of 120
  Figure 0-3 Surge Suppressor Sides 1.11.1 Surge Suppression Unit Location Lightning arrestors and surge protectors should be installed at all input/output points on the Libra MAX-58 equipment. Additionally, they should be properly grounded by connecting the body of the arrestor or protector to the grounding system with a heavy gauge (6 AWG) copper wire. This grounding wire should be as short as possible. The following figures illustrate the locations where the surge suppressors must be installed, when cabling both the base station and the subscriber station. Figure 0-4 Libra MAX-58 Base Station Surge Suppressor Diagram, illustrates where the surge suppressors must be installed when cabling the equipment for a Libra MAX-58 sector. Libra MAX User Guide  Pre-installation: Lightning Protectors  Page 21 of 120
  Figure 0-4 Libra MAX-58 Base Station Surge Suppressor Diagram Figure 0-5 Subscriber Station (MAX-SP) Surge Protector Diagram with Integrated Antenna illustrates where the surge suppressors must be installed when cabling the equipment. This diagram takes the integrated antenna into account. Libra MAX User Guide  Pre-installation: Lightning Protectors  Page 22 of 120

Libra MAX User Guide  Pre-installation: Lightning Protectors  Page 23 of 120
  Figure 0-6 Subscriber Station (MAX-SP) Surge Protector Diagram with External Antenna When installing surge suppressors between your outdoor unit and the antenna, use protectors that provide a DC short such as an L-C circuit or one quarter-wave shorting stub. These protectors should be physically located as close as possible to the ODU, preferably no further than five (5) feet (1.52 metres). Also, a star configuration should be used when grounding your surge suppressors.  1.12 Weatherproofing Connectors One of the most common installation problems is water intrusion, due to improper weatherproofing. Unfortunately, this activity is often overlooked and can lead to costly repairs and unnecessary expenses if not completed properly or not performed at all. Therefore, it is extremely important to properly weatherproof your connectors. An additional reason for using tape to weatherproof your cable connections is to prevent the connection loosening, due to environmental conditions. One method is to apply two layers of high quality rubber tape to the connectors, then apply two layers of high quality vinyl electrical tape, such as: Libra MAX User Guide  Pre-installation: Weatherproofing Connectors  Page 24 of 120
 Libra MAX User Guide  Pre-installation: CAT-5 Ethernet Cable Shielding  Page 25 of 120 • Scotch® 130C Linerless Rubber Splicing Tape • Scotch® Super 88 Premium Vinyl Electrical Tape Corrosion is another problem that arises if your cabling system is not properly weatherproofed. Corrosion can lead to high impedance at contact points, which can drastically reduce the effectiveness of your lightning protection. To help stop corrosion, you should use an anti-oxidizing paste on all contacts. When using anti-oxidization paste, keep the following guidelines in mind: • read the instructions and warnings for the selected product • lock washers should be used since the anti-oxidization paste acts as a lubricant • use a small amount. A thin film applied to exposed surfaces and on contact points is adequate • do not apply the anti-oxidization paste to the data cable connections on the outdoor unit. The anti-oxidization paste is conductive and may degrade performance and damage equipment. • using electrical or rubber tape is not recommended for sealing the grounding connections when anti-oxidization paste is used • do not use thread-locking compound on the same bolt or screw as anti-oxidization paste is used. 1.13 CAT-5 Ethernet Cable Shielding Using shielded CAT-5 Ethernet cable is very important when installing your BS or SS ODU, as it will help in reducing data errors caused by nearby interference. It is also very important that the shield be connected at only one end of the cable, the end that connects to the indoor unit. This is required to eliminate ground loops caused by current flowing between the indoor and outdoor units, due to a possible difference in ground levels. Such currents can damage equipment at either end or introduce noise that will interfere with the user data traffic on the cable.
 Base Station Installation This chapter discusses how to install your Libra MAX-58 base station equipment. There are four general tasks that you will need to perform when you install your Libra MAX-58 base station. They are: 1. base station indoor unit installation 2. base station outdoor unit installation 3. mounting the antenna 4. cabling the base station Please review the Pre-installation chapter before you begin installing your base station equipment. 1.14 Installing the Indoor Unit This Step applies to the MAX-HD ONLY. The MAX-RBS and MAX-LT units do not have an indoor unit component. Your first task is to install the base station’s indoor unit.  Before you begin, review the material in the Pre-installation chapter of this manual and make certain that you have met all of the conditions laid out there. Also, when you first receive your Libra MAX-58 indoor unit, the power supply, and fan tray and filter should already be installed in the chassis. If these two components, or any other components, are not installed, or if you are adding functional components to the chassis, this procedure will instruct you in their installation.  If the components are installed from the factory, ignore those steps that deal with component installation. Visually inspect the chassis’ back plane connector pins, in both the front and rear card slots, before you begin to install your indoor unit’s chassis.

 1.15 Installing the BS Outdoor Unit This chapter discusses how to install your Libra MAX-58 Base Station Outdoor Unit equipment. There are four general tasks that you will need to perform when you install your Libra MAX-58 subscriber station. They are: 1. configuring your outdoor unit equipment 2. installing your outdoor unit equipment 3. mounting the antenna, if the equipment uses a separate antenna 4. cabling the outdoor unit Please review the Pre-installation chapter before you begin installing your equipment. 1.16 Connecting the Ethernet Cable Before you mount your outdoor unit, either on a pole or a wall you will need to temporarily connect an Ethernet cable between the unit and your computer’s Ethernet port.  This is to allow you to configure your outdoor unit. If connecting the unit directly to a laptop or PC, a crossover Ethernet cable is required. For information on configuring your outdoor unit for the first time, refer to the chapter Base Station Configuration and Management. 1.17 Mounting Conditions The two (2) general subscriber station mounting scenarios are: 1. pole mount 2. wall mount 1.18 Pole Mounting If you are mounting your Base Station Outdoor Unit using an external antenna, you will not have to concern yourself with the polarization of the antenna.  In this instance, attach the mounting bracket unit anchor to the side of the unit housing as shown in the figure below.  Figure 0-17 Mounting Bracket Unit Anchor Libra MAX User Guide  Base Station Installation: Installing the BS Outdoor Unit  Page 35 of 120
  Figure 0-18 Attaching the Mounting Bracket Unit Anchor 1.19 Pole-mounting the Outdoor Unit Your next task is to install the Base Station outdoor unit.  Before you begin, review the material in the Pre-installation chapter of this manual and make certain that you have met all of the conditions laid out there.  Also, you should make certain that all of the necessary brackets and bolts are included in the box with your unit. To mount your outdoor unit on a pole: 1. Mount the outdoor unit on the pole. 1.1. Mount the bracket clamp to the pole, as shown in the figure below. If the pole is two (2) inches (5.08 cm) in diameter or less, turn the mounting bracket clamp back over so that the angle faces the pole.  This will allow you to mount the bracket to a smaller pole.  Figure 0-19 Attaching the Bracket to the Pole 1.2. Tighten the bolts so that the bracket will not move.  The recommended maximum torque is 24 N/m (17.7 ft/lbs).

Secure the unit to the pole, as shown in the figure below.  Figure 0-21 Securing the Base Station to the Pole 1.5. Tighten the pivot nut and bolt.  The recommended maximum torque is 24 N/m (17.7 ft/lbs). If your subscriber station has an integrated antenna, do Libra MAX User Guide  Base Station Installation: Pole-mounting the Outdoor Unit  Page 37 of 120
 not tighten the pivot nut and bolt until you have aligned your antenna. 1.20 Wall-mounting the Outdoor unit 1. To mount your outdoor unit to a wall: 1.1. Prepare the wall to hold the mounting bracket. The type of mount you create will depend upon the type of wall surface and material your wall is made of.  It may be that you only need to drill holes and insert bolt anchors, or you may have to fabricate a strong mount that will withstand the unit’s weight, outside temperature change, or other variables. For this reason, EION requires that you supply your own fastening bolts, lag-screws, or other fastening devices. 1.2. Place the back of the bracket against the wall mount, as shown below.  Figure 0-22 Bolting the Wall-side Bracket to the Wall 1.3. Secure the mounting bracket to the wall, using the necessary bolts. 1.4. Bolt the bracket’s unit anchor to the base station outdoor unit’s housing, as shown below.

 1.5. Tighten the bolts so that they are snug.  Do not over tighten the bolts, as they could crack the housing.  The recommended maximum torque is 5.7 N/m (4.2 ft/lbs). 1.6. Connect the base station ODU to the mounted wall-side bracket, using the pivot arm, as shown below.   Figure 0-24 Bolting the Subscriber Station to the Wall Bracket How you connect your grounding cable to a common earth ground will depend on how you have prepared the installation site and where the outdoor unit is installed.  For more information on outdoor unit grounding requirements, refer to the Outdoor Unit Grounding section of this manual. 1.21 Antenna Mounting Guidelines It is essential that you properly install your base station's antenna.  This ensures that your system is operating at optimum performance and aids in protecting it against lightning damage. To correctly install your antenna, it is very important that you follow your antenna manufacturer's installation instructions closely.  In addition, keep the following guidelines and practices in mind while performing your installation. 1.21.1 Mounting the Structure Make certain that the mounting structure (i.e.: pole mount, wall mount, etc.) is perpendicular to the horizontal, as shown below.  This is essential, because the antenna’s mechanical tilt indicator or indicators rely on using a vertical mounting surface for its reference point.  The degree of vertical accuracy should be checked and, if necessary, corrected prior to the installation of the antenna.  The mounting surface's vertical angle can be verified using a level or angle indicator. Libra MAX User Guide  Base Station Installation: Antenna Mounting Guidelines  Page 39 of 120
  Figure 0-25 Vertical Mounting Surface 1.22 Cabling the Base Station Once you have installed and mounted all of your Libra MAX-58 base station equipment, you will need to connect all of the cables required to power the units and transmit the data.  This will require that you connect all of the power and data cables to the base station’s indoor unit, then connect all of the cables between the indoor unit and the outdoor unit, then finally connect the cables between the outdoor unit and the antenna. Libra MAX User Guide  Base Station Installation: Cabling the Base Station  Page 40 of 120
  Figure 0-26 Libra MAX-58 Base Station Layout Diagram A Libra MAX-58 BS ODU can be connected to the Indoor Unit (IDU chassis) in one of two ways. One way is to connect the ODU directly to the chassis using the PoE cards with power provided by the 48V power supply. The other method is to connect the BS ODU to the switch fabric card with power supplied by an External PoE injector. The following layout diagram shows both of these options. The two different cabling options are further explained with lightning and surge protection in the diagrams that follow. The following sections set out the steps that you should follow in order to install the cables needed by your Libra MAX-58 base station.

 1.23 Weatherproofing Cable Connections One task that is extremely important is weatherproofing the connections between your cable and an outdoor unit or antenna.  Not only does this prevent corrosion and keep water from interfering with the connection, it also aids in keeping the connection tight. In general, you will weatherproof two types of connection, cable to outdoor unit or antenna and cable to cable. 1.23.1 Cable to Outdoor Unit Connections Most antenna or outdoor unit problems are caused by coaxial cable connections that loosen due to vibration, allowing moisture to penetrate the connector interface.  EION recommends that all outdoor unit to cable connections be weatherproofed using a procedure similar to the one described below. Fasten connectors securely together, as shown in below.  Ensure the connector and cables are free of foreign substances such as oil, water, grease, dirt, etc.  Figure 0-29 Secure Connector Tightly wrap two (2) layers of rubber splicing tape over the connection extending one (1) inch (2.54 cm) beyond the connectors and overlapping the tape on each turn, as shown below.  Figure 0-30 Wrap two layers of rubber tape Tightly wrap two (2) layers of electrical tape over the rubber splicing tape extending one (1) inch (2.54 cm) beyond the rubber splicing tape, as shown below.  Figure 0-31 Wrap two layers of electrical tape 1.23.2 Cable to Cable Connections Problems that occur in coaxial cable connections are often due to moisture penetration and corrosion in loose connections, caused by vibration.  EION recommends that all cable to cable connections be weatherproofed using a procedure similar to the one described below. Fasten connectors securely together, as shown below.  Ensure the connector and cables Libra MAX User Guide  Base Station Installation: Weatherproofing Cable Connections  Page 44 of 120
 are free of foreign substances such as oil, water, grease, dirt, etc.  Figure 0-32 Secure connection Tightly wrap two (2) layers of rubber splicing tape over the connection extending one (1) inch (2.54 cm) beyond the connectors and overlapping the tape on each turn, as shown below.  Figure 0-33 Wrap two layers of rubber splicing and electrical tape Tightly wrap two (2) layers of electrical tape over the rubber splicing tape extending one (1) inch (2.54 cm) beyond the rubber splicing tape, as shown below. 1.24 Installing a Drip Loop Another preventative measure that you can perform is to install a drip loop, as shown in the figure below.  Drip loops should be incorporated into the cable before it is connected to outdoor devices, such as outdoor units, antennas, etc.  For example, if you are installing one of the cables that run between the indoor unit and outdoor unit, you may want to install a drip loop in the cable immediately before it enters the building. Libra MAX User Guide  Base Station Installation: Installing a Drip Loop  Page 45 of 120
  Figure 0-34 Cable Drip Loop Drip loops should be incorporated into a system’s external cabling at any point where a connection is made.  Some examples of where a drip loop should be used are: • cable to outdoor unit connection • cable to antenna connection • cable to cable connection • the junction where a cable enters a building or structure • a common grounding junction box or bar 1.25 Cabling the Indoor Unit Your first task in cabling your Libra MAX-58 base station is to connect all of the wires and cables to your indoor unit.  To cable your indoor unit: Connect the PoE translation card’s power plug to the DC power supply leads, as shown in the figure on the next page. Libra MAX User Guide  Base Station Installation: Cabling the Indoor Unit  Page 46 of 120
  Figure 0-35 Wiring the PoE Card Power Plug Connect the power plug to the PoE translation card, as shown in the figure below.  Figure 0-36 Plugging the DC Power Plug Into the PoE Card Connect the Ethernet cable to the PoE card, as shown in the figure below.  Figure 0-37 Connecting the Ethernet Cable to the PoE Card Plug the DC power supply’s power cord into your power bar or an Uninterruptible Power Supply (UPS). If using the EION switch fabric card, the power is supplied to the ODU using an external power supply connected to an AC power source. Libra MAX User Guide  Base Station Installation: Cabling the Indoor Unit  Page 47 of 120
 1.26 Cabling to the Outdoor Unit Once you have finished cabling your indoor unit, you will need to run your cables and connect them to the outdoor unit.  To cable your outdoor unit: Run the Ethernet cable from the inside of your site, through your building wall opening, to the outside of your building.  How the cable will be run will depend on the strategy you used to create the building opening and, as such, cannot be defined here. Connect the Ethernet cable to the outdoor unit 8-pin DIN female circular connector, as shown in the figure below.  Figure 0-38 Connecting the Ethernet Cable to the ODU Weatherproof the connection, as described above. 1.27 Cabling to the Antenna To connect the radio frequency cable between the base station’s outdoor unit and the antenna, perform the following steps: 1. Connect the radio frequency cable to the outdoor unit socket labeled ANT. 2. Weatherproof the cable connection, as outlined on page 44 above. 3. Connect the surge suppressor to the cable, per the manufacturer’s instructions. Selection of the lightning protector should be of the Non DC Pass as this will also aid in the prevention of static discharge damaging the equipment or degrading performance by introducing noise to the receiver portion of the outdoor unit. 4. Weatherproof the suppressor connection, as outlined on page 44 above. 5. Connect the cable from the surge suppressor to the antenna, per the manufacturer’s instructions. 6. Weatherproof the suppressor connection, as outlined on page 44 above. Libra MAX User Guide  Base Station Installation: Cabling to the Outdoor Unit  Page 48 of 120
 7. Ground the suppressor to a common earth ground, per the manufacturer's instructions. RF cable sections (before and after the suppressor) should be kept as short as possible. 1.28 Connecting the Ethernet Cable You will need to connect your base station to your network via Ethernet. Connect an Ethernet cable to your base station to either of the two ports shown shown below. If you are connecting your base station’s Ethernet port directly to a computer, you will need to use a cross-over cable for the connection.  Figure 0-39 Connecting an Ethernet Cable to the Sector Card’s Ethernet Port 1.29 Powering on the Base Station Once all of the equipment has been installed and cabled, you should connect the power to the base station and power it on to check that all components are operating correctly. You can use either AC or DC power for your base station, depending on your needs and the chassis you choose to use. 1.29.1 AC Power The AC chassis requires that you use both AC and DC to power the base station chassis and components.  AC is used to power the chassis itself and all of the cards installed in it, through the built-in power supplies.  The DC is used to provide the -48V power to the outdoor units, through the PoE card or cards. To plug your base station into an AC mains outlet: 1. Plug the AC power cord into the indoor unit chassis’ AC power socket, as shown below. Libra MAX User Guide  Base Station Installation: Connecting the Ethernet Cable  Page 49 of 120
  Figure 0-40 AC Power Socket 2. Connect the DC power cord(s) from the DC power supply to the indoor unit chassis’ DC Power Connectors, shown in Figure 0-40 AC Power Socket. 3. Plug the AC power cord into your power bar or UPS.  Make certain that your power bar or UPS is plugged into the AC wall outlet. 4. Turn on the indoor unit chassis power switch, shown in the above figure. When the base station is first powered up, it takes roughly four (4) minutes for the sector card to boot up.  You cannot use the sector card until it has booted up completely. 1.29.2 DC Power The DC variant of the indoor unit’s chassis does not need any AC power to operate, it only uses -48V DC power.  You will, however, need to run a power jumper from the DC power distribution panel sockets to the PoE card DC power sockets before you can use the base station. To plug your base station into a DC mains outlet: 1. Run a patch cord from each one of the DC power distribution panel sockets to one of the PoE card DC power sockets, shown in Figure 0-41 DC Power Sockets below. Make certain that you connect all of the installed PoE cards to the DC power sockets.  Figure 0-41 DC Power Sockets Libra MAX User Guide  Base Station Installation: Powering on the Base Station  Page 50 of 120
 2. Connect the DC power cord(s) from the DC power supply to the indoor unit chassis’ DC Power Terminals, shown above. 3. Turn on the indoor unit chassis circuit breakers, shown above. When the base station is first powered up, it takes roughly four (4) minutes for the sector card to boot up.  You cannot use the sector card until it has booted up completely.

Drip loops should be incorporated into the cable before it is connected to outdoor devices, such as outdoor units, RBS, antennas, etc.  For example, if you are installing one of the cables that run indoors from an RBS, you may want to install a drip loop in the cable immediately before it enters the building.  Figure 0-18 Cable Drip Loop Drip loops should be incorporated into a system’s external cabling at any point where a connection is made.  Some examples of where a drip loop should be used are: • cable RBS connection • cable to antenna connection • cable to cable connection • the junction where a cable enters a building or structure Libra MAX User Guide  Rapid Backhaul System Installation: Installing a Drip Loop  Page 63 of 120
 • a common grounding junction box or bar 1.35 Cabling to the RBS To cable your RBS unit: Run the Ethernet cable from the inside of your site, through your building wall opening, to the outside of your building.  How the cable will be run will depend on the strategy you used to create the building opening and, as such, cannot be defined here. Connect the Ethernet cable to the RBS unit 8-pin DIN female circular connector, as shown in the figure below.  Figure 0-19 Connecting the Ethernet Cable to the RBS Weatherproof the connection, as described above. 1.36 Cabling to the Antenna To connect the radio frequency cable between the RBS unit and the antenna, perform the following steps: 8. Connect the RF cable for the antenna that is pointing at a subscriber station to the RBS socket labeled ANT. 9. Connect the RF cable for the antenna that is pointing at a Base Station to the RBS socket labeled IF. 10. Weatherproof the cable connection, as outlined on page 44 above. 11.

It allows configuration of the following:  Figure 0-4: Basic Configuration BS ODU ID – It is a globally unique numeric identifier for the BS ODU and hence the network.  It is 6 bytes (48 bits) in length. This identifier has to be entered in the subscriber stations for them to communication with this particular BS. By default this is set as the MAC Address of the BS ODU. The Base Station must be rebooted for changes to the BS ODU ID to take effect. NMS Source – It configures whether the NMS and AAA server to be used should be loaded from the BS ODU itself or a sector card with standalone NMS/AAA server. This has to be set to BS_ODU for MAX-LT. For MAX-HD it can be set to either BS_ODU or SECTOR_CARD as needed. The Base Station must be rebooted for changes to the NMS Source to take effect. Libra MAX User Guide  Base Station Configuration: Base Station Configuration (BS)  Page 70 of 120
 BS ODU MAC Address – It displays the MAC address of the active port of the BS ODU.  This MAC address has to be configured into subscriber stations if you want them to specifically connect to the particular BS ODU of interest. MAC address is not configurable by user. BS ODU IP Address – It is the IP of the active port of the BS ODU. IP address has to be in the same subnet as the subscriber station. The Base Station must be rebooted for changes to the BS ODU IP Address to take effect. Note that if the IP Address is changed, you will need to login using the newly configured IP address. NOTE: The default BS ODU IP Address is 192.168.1.40 DHCP Enable – Setting it to ‘Enable’ activates a DHCP server in BS ODU so that subscriber stations associated with it can receive IP address automatically. It is disabled by default. The Base Station must be rebooted for changes to DHCP to take effect. Syslogd – It configures where the log files for the BS ODU are stored. Its value is set to ‘Local’ by default. The Base Station must be rebooted for changes to the Syslogd to take effect. 1.39.2 VLAN Configuration Currently the VLAN setting allows users to configure a management VLAN. This allows network administrators access to the management GUI over a specified VLAN. Support of Management VLAN will prevent this and will allow access to the Base Station only from the specified VLAN (Management VLAN). So, the Base Station can be accessed and managed only from a system that is in the specified VLAN either on the Ethernet side of the Base Station or on any of the associated Subscriber Stations network. The following figure depicts this behavior when a Management VLAN is specified in the Base Station. Libra MAX User Guide  Base Station Configuration: Base Station Configuration (BS)  Page 71 of 120
  Figure 0-5: Base Station configured with a management VLAN In the above figure, the Base Station is configured with a Management VLAN ID 100. So, only PC1 and PC3 that are part of VLAN 100 can access the Base Station. The other PCs cannot access the Base Station.  In the VLAN management screen, VLAN Management can be enabled or disabled and a Management VLAN ID can be configured. The default management VLAN ID is ‘1’. The allowed range of VLAN IDs is from 0 to 4092.

  Figure 0-19: Upstream QoS Configuration for BE After configuring the QoS for downstream, click on ‘Back to QoS List’ on top and then add another QoS, this time for the downstream.    Figure 0-20: Downstream QoS Configuration for BE At least one uplink and one downlink classifier need to be defined for successful communication between the base and subscriber stations.  Number – This should be a unique identifier given manually by the operator for ease of use. Service Class Name – A unique class name given to identify the service  (DL or UL) & its capabilities (data rates).  Example: SF_<Direction (UL/DL)>_<Data Rate (1024000bps)> Direction – It provides the direction of the service flow whether in down-link or up-link. Default is set for Request transmission policy. At least one upstream and one downstream classifier have to be assigned to a SS. Libra MAX User Guide  Base Station Configuration: Subscriber Station Association (SS)  Page 85 of 120
 Service Flow Scheduling Type – The value of this parameter specifies the scheduling service that shall be enabled for the associated service flow. CS Specification – Service-specific CS resides on top of the MAC CPS and utilizes, via the MAC SAP (Service Access Point), the services provided by the MAC CPS (Common Part Sub layer). Recommended value is ‘Packet, IPv4 over 802.3/Ethernet’. Traffic Priority – The value of this parameter specifies the priority assigned to a service flow. Given two service flows identical in all QoS parameters besides priority, the higher priority service flow should be given lower delay and higher buffering preference. This field is mandatory for nrtPS. Its default and the minimum value is 0 and the maximum value is 7. Maximum Sustained Traffic – This parameter defines the peak information rate of the service. The rate is expressed in bits per second and pertains to the SDUs at the input to the system. If this parameter is omitted or set to zero, then there is no explicitly mandated maximum rate. This field specifies only a bound, not a guarantee that the rate is available. This field is mandatory for BE. Its minimum value is 0 and the maximum value is 20480000 bps. Maximum Traffic Burst – This parameter defines the maximum burst size that shall be accommodated for the service. Since the physical speed of ingress/egress ports, the air interface, and the backhaul will, in general, be greater than the maximum sustained traffic rate parameter for a service, this parameter describes the maximum continuous burst the system should accommodate for the service. Minimum Reserved Traffic – This parameter specifies the minimum rate reserved for this service flow and is equal to (SDU Size)*8/(Maximum Latency). The rate is expressed in bits per second and specifies the minimum amount of data to be transported on behalf of the service flow when averaged over time. It is disabled by default. Min Tolerable Traffic – This parameter specifies the minimum tolerable rate in bits per second for this service flow. This value should not be higher than the corresponding Minimum Reserved Traffic Rate value. The difference between these two values reflects SDUs’ loss rate. It is disabled by default. Unsolicited Grant Interval – The value of this parameter specifies the nominal interval in milliseconds between successive data-grant opportunities for this Service Flow. The maximum unsolicited grant interval field specifies only a bound. It is applicable to UGS. It is disabled by default. Its minimum value is 0 and maximum value is 100 ms. Unsolicited Polling Interval – This parameter defines the maximum nominal interval in milliseconds between successive polling grants opportunities for a DL and UL service flow. If this parameter is set to zero, then there is no explicitly mandated unsolicited grant interval. It is mandatory for Best Effort, nrtPS and rtPS services in Uplink direction only. Its default and minimum value is 0 ms and maximum value is 5000 ms. FSN Size – This indicates the size of the FSN for the connection that is being setup. A value of 0 indicates that FSN is 3-bit long and a value of 1 indicates that FSN is 11-bit long. It is mandatory for rtPS service. Its default value is set at 11-bit FSN. Tolerated Jitter – This parameter defines the maximum delay variation (jitter) for the connection. It is disabled by default. It is mandatory for UGS service. Its minimum value is 0 ms and the maximum value is 2048 ms. Libra MAX User Guide  Base Station Configuration: Subscriber Station Association (SS)  Page 86 of 120
 Maximum Latency – The value of this parameter specifies the maximum latency between the reception of a packet by the BS or SS on its network interface and the forwarding of the packet to its RF Interface. It is disabled by default but is mandatory for rtPS and UGS services. Its minimum value is 0 ms and the maximum value is 2048 ms. Request Transmission Policy – The value of this parameter provides the capability to specify certain attributes for the associated service flow. One or more can be chosen in these parameters. Only a few options are enabled depends on the service type. Shall not Include CRC in the MAC PDU: If checked, the service flow shall not include CRC in the MAC PDU. If unchecked, this feature is on and will request bandwidth using CRC in the MAC PDU (if CRC in the MAC PDU groups are created). Shall not use Packing: If checked, the service flow shall not pack multiple SDUs (or fragments). If unchecked, this feature is on and will request bandwidth using  packing (if packing groups are created at BS). Shall not suppress payload headers (PHS): If checked, the service flow shall not suppress payload headers (CS parameters). If unchecked, this feature is on and will request bandwidth using suppress payload headers (if PHS groups are created at BS). PHS is disabled by default. Shall not Use uplink Piggyback requests with data: It is applicable to Upstream QoS.  If checked, the service flow shall not piggyback requests with data. Please keep this checked. If unchecked, this feature is on and will request bandwidth using uplink piggyback requests (if Piggyback groups are created at BS) Default: Piggyback is off.  Shall not Use Fragmentation: If checked, the service flow shall not fragment data. If unchecked, the feature is on. The packets can be fragmented and sent to SS on this service. The number of bits in FSN Size is used as the sequence number of the fragmented packet. Shall not Use UL Broadcast-Bandwidth request opportunities: It is applicable to Upstream QoS.  If checked, service flow shall not request broadcast bandwidth request opportunities. Please keep this option checked. Libra MAX User Guide  Base Station Configuration: Subscriber Station Association (SS)  Page 87 of 120
 If unchecked, the feature is on. This particular service flow will request bandwidth using uplink broadcast request opportunities. Broadcast bandwidth request is done on the contention slot. Shall not use UL multicast bandwidth request opportunities: It is applicable to Upstream QoS.  If checked, service flow shall not request bandwidth using multicast connection identifiers. If unchecked, the feature is switched on. This particular service flow will request bandwidth using multicast connection identifiers. 1.40.2 SS List Subscriber stations are added in this section.  MAC Address – This parameter provides MAC address of SS. This is unique for a particular SS. This is also used as SS ID to identify as SS. In order for the SS to associate with the BS, correct OFDM MAC address of the SS has to be entered in the SS list. This MAC address is printed on the label of the SS and can also be obtained by logging into a SS. Please refer to ‘SS Manager Configuration Guide’ for detail information. SS Name – A unique user name should be given to the SS to identify it. It can also give the location or the customer name to represent the SS. PCID – PCID is used to associate a set of QOS parameters to the SS for downlink and uplink service flow that are created with ‘Add QoS’. A number of PCIDs can be selected depending on requirements. Once PCIDs are selected, the user can associate classifiers which each PCID. Classifiers are used to associate a particular traffic data to the Service flow (identified by QOS parameters in BS). 1.40.3 Adding a Subscriber Station  To add a subscriber station, click on ‘SS’ and then ‘SS List’ the following screen appears. Sample subscriber station may have been added by default. You can also choose to edit it or start by adding a new one. Libra MAX User Guide  Base Station Configuration: Subscriber Station Association (SS)  Page 88 of 120
  Figure 0-21: SS List Menu To add a subscriber station, click on ‘Add New SS’ and it will prompt for name and MAC address of the SS. Provide a unique name for the SS. Enter MAC address of the subscriber you would like the BS to communicate with. Then click on ‘Save SS’ to save before moving on to adding classifiers. MAC addresses must be entered using lowercase characters  Figure 0-22: Configure Name and MAC Address of SS After saving the name and MAC address of the subscriber station, the following screen appears.  Figure 0-23: Assigning QoS to Subscriber Station Libra MAX User Guide  Base Station Configuration: Subscriber Station Association (SS)  Page 89 of 120
 Click on ‘Add QoS’ to assign QoS to the subscriber station.  Figure 0-24: Screen after assigning Uplink and Downlink QoS to SS 1.40.4 Classifiers Classifiers are used for routing of packets to particular SS using IP rules (Classifier maps an IP packet to a particular connection). Its length is 2 bytes (maximum number of classifiers that the SS supports). It is mandatory to have classifiers for each PCID.  Type – There are two types of classifiers. Static: User has to add the IP address of the system or router on the subscriber station side as a classifier. Dynamic: If DHCP is enabled at the subscriber station side, it will obtain an IP address dynamically. In this case DHCP must be enabled at PC/Router connected to the subscriber station. Index – This specifies the priority for the classifier, which is used for determining the order of the classification. Classifiers may have priorities in the range 0–255 with the default value being 0. Type of Service – The values of this field specify the matching parameters for the IP type of service byte range and mask. An IP packet with IP type of service (ToS) byte value “ip-tos” matches this parameter if tos-low ≤ (ip-tos AND tos-mask) ≤ tos-high. If this field is omitted, then comparison of the IP packet ToS byte for this entry is irrelevant. Minimum: 0 (for low, high and mask) Maximum: 65535 (for low, high and mask) IP Source Address and Mask – This parameter specifies a IP source address (designated “src”) and its corresponding address mask (designated “dmask”). An IP packet with IP destination address “ip-dst” matches this parameter if src = (ip-dst AND dmask). If this parameter is omitted, then comparison of the IP packet source address for this entry is irrelevant. Protocol Source Port Range: The value of the field specifies a range of protocol source port values. Classifier rules with port numbers are protocol specific; i.e., a rule on port numbers without a protocol specification shall not be defined. An IP packet with Libra MAX User Guide  Base Station Configuration: Subscriber Station Association (SS)  Page 90 of 120
 protocol port value “src-port” matches this parameter if src-port is greater than or equal to sport low and src-port is less than or equal to sport high. If this parameter is omitted, the protocol source port is irrelevant. This parameter is irrelevant for protocols without port numbers.  Minimum: 0 (low, high and mask) Maximum: 65535 (low, high and mask) Protocol Destination Port Range – The value of the field specifies a range of protocol destination port values. Classifier rules with port numbers are protocol specific; i.e., a rule on port numbers without a protocol specification shall not be defined. An IP packet with protocol port value “dst-port” matches this parameter if dst-port is greater than or equal to dport low and dst-port is less than or equal to dport high. If this parameter is omitted the protocol destination port is irrelevant. This parameter is irrelevant for protocols without port numbers. Minimum: 0 (low, high and mask) Maximum: 65535 (low, high and mask) Ethernet Source MAC Address – This parameter specifies a MAC source address (designated “src”) and their corresponding address mask (designated “msk”). An IEEE 802.3/Ethernet packet with MAC source address “ethersrc” corresponds to this parameter if src = (ethersrc AND msk). If this parameter is omitted, then comparison of the IEEE 802.3/Ethernet source MAC address for this entry is irrelevant. Notation: xx:xx:xx:xx:xx:xx Ethernet Destination MAC Address – This parameter specifies a MAC destination address (designated “dst”) and its corresponding address mask (designated “msk”). An IEEE 802.3/Ethernet packet with MAC destination address “etherdst” corresponds to this parameter if dst = (etherdst AND msk). If this parameter is omitted, then comparison of the IEEE 802.3/Ethernet destination MAC address for this entry is irrelevant.  Notation: xx:xx:xx:xx:xx:xx The format of the Layer 3 protocol ID in the Ethernet packet is indicated by type, eprot1, and eprot2 as follows: If type = 0, the rule does not use the Layer 3 protocol type as a matching criteria. If type = 0, eprot1, eprot2 are ignored when considering whether a packet matches the current rule. If type = 1, the rule applies only to SDUs that contain an Ethertype value. Ethertype values are contained in packets using the DEC-Intel-Xerox (DIX) encapsulation or the Sub-Network Access Protocol (SNAP) encapsulation (IEEE 802.2, IETF RFC 1042) format. If type = 1, then eprot1, eprot2 gives the 16 bit value of the Ethertype that the packet shall match in order to match the rule. If type = 2, the rule applies only to SDUs using the IEEE 802.2 encapsulation format with a Destination Service (DSAP) other than 0xAA (which is reserved for SNAP). If type = 2, the lower 8 bits of the eprot1, eprot2 shall match the DSAP byte of the packet in order to match the rule. Libra MAX User Guide  Base Station Configuration: Subscriber Station Association (SS)  Page 91 of 120
 If the Ethernet SDU contains an IEEE 802.1D and IEEE 802.1Q Tag header (i.e., Ethertype 0x8100), this object applies to the embedded Ethertype field within the IEEE 802.1D and IEEE 802.1Q header. To add a classifier, go to ‘SS List’ window and click on the subscriber of interest in the list. Then on the screen that appears as shown on Figure 0-24. Click on ‘Add Classifier’ next to ‘QoS Name’ and the following screen appears.  Figure 0-25: Adding Classifier Next, select the classifier type to be based upon. Ethernet Destination Address is chosen in the following example.

Libra MAX User Guide  Base Station Configuration: Utilities  Page 94 of 120
 1.42.4 Backup Configuration Use this feature to save an existing configuration file. When the “Download” button is pressed, the user will be prompted to download a compressed configuration file that can be saved on the local computer. This file can be used to recover a lost configuration, or to load a second base station with similar settings. The configuration can be re-loaded using the Upload Configuration function.  Figure 0-29: Download Backup Configuration 1.42.5 Upload Configuration Once you have saved a configuration file, the tar.gz file can be used to restore the previous configuration of the base station, or to load a known good configuration from another base station. NOTE: Prior to restoring a configuration, EION recommends that the Base Station is reset to default values and rebooted. ATTENTION: Ensure that the configuration filename is saved as “config.tar.gz” Special characters in the filename will cause the upload configuration to fail.  Figure 0-30: Upload Configuration Page To restore a configuration tar.gz file, place the file on an FTP server that is accessible from the base station. Enter the path to the configuration file in the “configuration file” field and the coordinates of the FTP server as shown in the example above. When the upload button is pressed, the tar.gz file will be loaded into the base station and the configuration will be overwritten. In order for the new settings to take effect, the base station must be rebooted.  NOTE: The existing GUI password will be overwritten by the password that was saved in the configuration being uploaded. 1.43 Restore Factory Default This feature sets all configurations to factory default, including IP address and frequency configuration. Major factory settings are as follows: Libra MAX User Guide  Base Station Configuration: Restore Factory Default  Page 95 of 120
          Parameter Value IP Address  192.168.1.40 NMS Server  192.168.1.40 AAA Server  192.168.1.40 Frequency: 5725000 kHz Channel Bandwidth  10 MHz BS Transmit Power  -50 dBm  Subscriber stations and QoS parameters are not restored by factory default. You will have to configure them manually. 1.44 IP Address Recovery Loss of the Base Station’s IP address leads to loss of accessibility to the Base Station and ability to manage the Base Station. This feature provides the ability to recover the accessibility to the Base Station by assigning a new IP address to the Base Station.   This feature would require a utility program called “iprecover” to be executed from a linux desktop that is connected to the Ethernet interface of the Base Station.  The iprecover utility can be executed as shown below. Executing the utility without specifying any parameters will display a brief help on the various parameters that should be provided while executing the utility.  Figure 0-31: Executing the IP recovery utility without specifying any parameters will display a help file  The values for each of the parameters in the iprecover utility adhere to the following: Libra MAX User Guide  Base Station Configuration: IP Address Recovery  Page 96 of 120
 • Source-intf-name is the name of the interface which is connected to the Base Station • Dest-MAC is the MAC Address of the Base Sation for which a new IP address has to be assigned. • New-IP-Addr is the IP Address that will be assigned to the Base Station • Target-intf-name must be IXP0 when assigning a new IP Address for the Base Station  An illustration of the command usage is shown below:  Figure 0-32: In this example, the IP address 192.168.2.41 is assigned to the Base Station having a MAC address 00:10:30:90:00:11 NOTE: The new IP address assigned after the above step is complete is only a temporary IP address and will not be reflected in the Base Station GUI. Also, the new IP Address will be lost when the Base Station is rebooted. Once the above step is completed and the Base Station is accessible with the new IP address, the IP address should be updated (or recorded) appropriately from the Base Station GUI to make it as a permanent IP address.

 Sector Card/Indoor Unit 1.45 Sector Card Management Sector card plugs into any of the gray slots of the indoor unit chassis and is a part of Libra MAX-HD Chassis. This allows configuration of multiple Base Stations as well as their monitoring. It also provides the data path for multiple BS ODUs to their data source (such as router or a switch) inside the NOC. Since one sector card can manage multiple BS ODUs, management of sector card itself is less frequent and is usually done at the time of its installation only. Most common parameters to be changed on sector card are time zone and its network parameters (such as IP address and subnet mask). Besides, sector card can be reset or shutdown using its management interface. 1.45.1 Accessing Sector Card  In order to access sector card, open a web browser and type the following URL: https://192.168.1.200:10101 Please note that it uses ‘HTTPS’ and that the IP address is factory default.

It contains two sub-sections – WiMAX Radio and Network. WiMAX settings deal with RF portion whereas Network is for IP settings. WiMAX Radio This section can be accessed by clicking on ‘Configuration’ and then on ‘WiMAX’. Radio or RF configuration is done on this section. It allows configuration of the following: Libra MAX User Guide  Subscriber Station Configuration: Screen Layout  Page 107 of 120
  Figure 0-3: WiMAX Radio Settings, AFS Disabled  Figure 4: WiMAX Radio Settings with AFS Enabled BS ID – It is the identifier of the BS to which the subscriber station is to be associated. It is usually the MAC of the BS ODU. By default, SS is configured to be associated with any Libra MAX-58 BS ODU. BS ID Mask – This is the mask for BS ID. Its default value is 00:00:00:00:00:00 Duplex Mode – This is set to TDD as only TDD is supported at present. AFS Support – Automatic Frequency Scanning mode allows selection of frequency automatically within the range and in step size specified. Set the start and end frequency range including the step size and a center frequency. Subscriber station will then scan within the range of frequencies and locks the center frequency to the one where the signal strength is optimum. DL-Center Frequency – This should be set to that of the BS ODU. For a SS to communicate with the BS, both have to be on the same frequency.  Since, it’s a TDD system, both uplink and downlink frequency will be the same. Channel Bandwidth – For BS Type FBW-1050 (5.725 to 5.875 GHz), channel bandwidth is 10 MHz. Larger the bandwidth, higher the throughput. Encryption Support – This field indicates Encryption Support is Enabled or not. This Libra MAX User Guide  Subscriber Station Configuration: Configuration  Page 108 of 120
 is disabled by default. DBPC Support – This field indicates DBPC (Down-Link Burst Profile Change) Support is Enabled or not. It is disabled by default. SMC Support – This field indicates SMC (Secondary Management Connection) is Enabled or not. It is disabled by default. 1.52 Network The following network related parameters are configured in this section.   Figure 0-4: Network Settings – Bridge Mode SS IP Address – This is the IP address of the subscriber station. SS Subnet Mask – Subnet mask of the subscriber station is configures in this section. SS MAC Address – MAC Address of the subscriber station is displayed here. This MAC address needs to be configured in the list of SS in the Base Station for them to communicate. Operation Mode – Subscriber station can work either in bridge mode or router mode. It operates at bridge mode by default. In the router mode, traffic IP and its subnet has to be configured.  Figure 0-5: Network Settings – Router Mode 1.53 Reboot This will reset the subscriber station. Configurations are still retained on reboot. 1.54 Restart This will stop and then restart the wireless interface of the subscriber station. It is recommended to restart subscriber station after making changes.

 Troubleshooting 1.60 Preventative Maintenance Administering and maintaining your system properly can prevent many problems and alert you to minor problems before they become serious. Some recommendations follow. • Measure and document system performance at the time of the original installation. • Change menu passwords so that only authorized people can reconfigure the system. • Maintain the integrity of the system design when adding to or changing a system. The introduction of new elements to a system can cause problems unless you revise the network plan to take into account the changes. For example, improper installation of a co-located antenna can add unwanted system interference. • Keep records of all changes. Especially document the addition of units, hardware and software changes, and changes to configuration settings. Configuration errors often cause other problems. Current records can be compared with original installation records and function as benchmarks to help in troubleshooting. • Keep a log of past and present problems and solutions. Store the log on-site for easy reference, if possible. The log identifies common failure points and fixes. Before contacting EION’s Technical Assistance Center, document the symptoms of the fault and the steps taken to diagnose and fix the problem. Record the current configuration of the system. • Perform preventive maintenance at a regular interval, for example every six months. • Perform link monitor tests to verify the system after periods of extreme weather, and inspect towers, antennas, ODUs, cables, and connectors for damage. • Monitor system performance regularly. Environmental change as well as normal wear and tear on components can affect system performance. • In some cases a bench test is a useful tool in diagnosing problems. 1.61 Troubleshooting Areas There are four areas to keep in mind with troubleshooting: 1. Network integrity: The continued performance and reliability of a network depend upon maintaining the integrity of the network. If you change a network’s design, you will affect its operation. Be aware of recent changes to your network. 2. Quality of RF links: Data communication depends first on good RF links. If you establish and maintain high-quality RF links, then you can be sure the links will carry high-speed data. If the quality of the RF links degrades for some reason, the quality of the data and the associated performance will also degrade. Libra MAX User Guide  Troubleshooting: Preventative Maintenance  Page 112 of 120
 3. Radio Hardware: This consists of three parts: Main unit, antenna, and mounting hardware.. (To verify the radio performance, you can run diagnostic tests, such as RSSI and CINR) 4. Correct Unit Configuration: Units must be configured properly, according to the network plan. Configuration errors can cause an inability to communicate or poor performance. The addition of units or other changes to your system may require you to change configuration settings. 1.62 Troubleshooting Chart Indication  Possible Cause  Corrective Action High BER  Signal strength is too low • Record RSSI to determine fade margin • Check for RF absorbent obstacles in the antenna path • Search for indirect RF paths between antennas (i.e. ones that use beneficial reflections or multipaths) • Check and replace cables if necessary • Reposition antenna or if possible remove obstruction High BER  Signal strength is too high • Adjust antennas • Increase distance between units to add attenuation • Adjust Tx Power level High BER  Interference  • Change center frequency • Increase RF power • Change polarization of antennas • Increase separation or change location of antenna • Increase separation between co-located antennas High BER  Radio Performance (Tx/Rx) • Contact EION Inc.

 Appendix A: Definitions Base station (BS): Generalized equipment set providing connectivity, management, and control of the subscriber station (SS). Subscriber station (SS): Generalized equipment set providing connectivity between subscriber equipment and a base station (BS). Multicast polling group: A group of zero or more subscriber stations (SSs) that are assigned a multicast address for the purposes of polling. Security association identifier (SAID): An identifier shared between the base station (BS) and subscriber station that uniquely identifies a security association (SA). IPV6: A network layer for packet-switched internetworks. It is designated as the successor of IPv4, the current version of the Internet Protocol, for general use on the Internet. Ipv4: The fourth iteration of the Internet Protocol (IP) and the first version of the protocol to be widely deployed. IPv4 is the dominant network layer protocol on the Internet and apart from IPv6 it is the only standard internetwork-layer protocol used on the Internet. MAC Address: Media Access Control Address, a quasi-unique identifier attached to most network adapters (NICs). It is a number that acts like a name for a particular network adapter. IP Address: A unique address that certain electronic devices currently use in order to identify and communicate with each other on a computer network utilizing the Internet Protocol standard (IP). SAID: Security Association Identifier is an identifier shared between the base station and a subscriber station that uniquely identifies a security association (SA). PCID: Provisional Connection identifier. It’s a provisional service given by the operator. PCID is equivalent to provisional service flow in IEEE 802.16D standard. QOS: Quality of Service refers to resource reservation control mechanisms rather than the achieved service quality. Quality of Service is the ability to provide different priority to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow. Classifier: A classifier is a set of matching criteria applied to each packet entering the IEEE standard 802.16 network. It consists of some protocol-specific packet matching criteria (destination IP address, for example), a classifier priority, and a reference to a CID. If a packet matches the specified packet matching criteria, it is then delivered to the SAP for delivery on the connection defined by the CID. Implementation of each specific classification capability (as, for example, IPv4 based classification) is optional. The service flow characteristics of the connection provide the QoS for that packet. Configuration: A set of parameters by which a BS (base station) is configured to take specific values and operate in that range.  Events: The information of the particular BS (base station) which is reported by a BS on occurrence of state changes and faults.  Slab: Identifies a period of time used for billing purposes. Upgrade: To update the software on the BS from existing load to another load. Mapped SS: Shows the numbers and the detail of the SS which are associated to the Libra MAX User Guide  Appendix A: Definitions: Troubleshooting Chart  Page 118 of 120
 Libra MAX User Guide  Appendix A: Definitions: Troubleshooting Chart  Page 119 of 120 particular BS UN Mapped SS: Unmapped SS are the SS which have been created by the operator and have not been associated to any BS yet. The SS will get associated with the BS once it starts communicating with the BS.  Deregister: This is the operation to delink the connectivity between the SS and BS.
