2-7Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation GuideOL-24247-01Chapter 2 Installing the Access Point Avoiding Damage to Radios in a Testing Environment•Select your installation site with safety, as well as performance in mind. Remember: electric power lines and phone lines look alike. For safety, assume that any overhead line can kill. •Call your electric power company. Tell them your plans, and ask them to come look at your proposed installation. •Plan your installation carefully and completely before you begin. Successful raising of a mast or tower is largely a matter of coordination. Each person should be assigned to a specific task and should know what to do and when to do it. One person should be in charge of the operation to issue instructions and watch for signs of trouble.•When installing the access point and antennas, remember:–Do not use a metal ladder.–Do not work on a wet or windy day.–Do dress properly—shoes with rubber soles and heels, rubber gloves, long sleeved shirt or jacket.•Use a rope to lift the access point. If the assembly starts to drop, get away from it and let it fall. •If any part of the antenna system should come in contact with a power line, do not touch it or try to remove it yourself. Call your local power company. They will remove it safely. If an accident should occur, call for qualified emergency help immediately.Avoiding Damage to Radios in a Testing EnvironmentThe radios on outdoor units (bridges) have higher transmit power levels than radios on indoor units (access points). When you test high-power radios in a link, you must avoid exceeding the maximum receive input level for the receiver. At levels above the normal operating range, packet error rate (PER) performance is degraded. At even higher levels, the receiver can be permanently damaged. To avoid receiver damage and PER degradation, you can use one of the following techniques:•Separate the omnidirectional antennas by at least 2 ft (0.6 m) to avoid receiver damage or by at least 25 ft (7.6 m) to avoid PER degradation.Note These distances assume free space path loss and are conservative estimates. Required separation distances for damage and performance degradation levels in actual deployments are less if conditions are not non-line-of-sight.•Reduce the configured transmit power to the minimum level.•Use directional antennas, and keep them away from each other.•Cable the radios together using a combination of attenuators, combiners, or splitters to achieve a total attenuation of at least 60 dB.For a radiated test bed, the following equation describes the relationships among transmit power, antenna gain, attenuation, and receiver sensitivity:txpwr + tx gain + rx gain - [attenuation due to antenna spacing] < max rx input levelWhere:txpwr = Radio transmit power leveltx gain = transmitter antenna gainrx gain = receiver antenna gain
2-8Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation GuideOL-24247-01Chapter 2 Installing the Access Point Installation GuidelinesFor a conducted test bed, the following equation describes the relationships among transmit power, antenna gain, and receiver sensitivity:txpwr - [attenuation due to coaxial components] < max rx input levelCaution Under no circumstances should you connect the antenna port from one access point to the antenna port of another access point without using an RF attenuator. If you connect antenna ports, you must not exceed the maximum survivable receive level of 0 dBm. Never exceed 0 dBm, or damage to the access point can occur. Using attenuators, combiners, and splitters having a total of at least 60 dB of attenuation ensures that the receiver is not damaged and that PER performance is not degraded.Installation GuidelinesBecause the access point is a radio device, it is susceptible to common causes of interference that can reduce throughput and range. Follow these basic guidelines to ensure the best possible performance:•For information on planning and initially configuring your Cisco Mesh network, refer to the Cisco Wireless Mesh Access Points, Design and Deployment Guide, Release 7.0.•Review the FCC guidelines for installing and operating outdoor wireless LAN devices at http://www.cisco.com/en/US/partner/prod/collateral/routers/ps272/data_sheet_c78-647116_ps11451_Products_Data_Sheet.html.•Perform a site survey before beginning the installation.•Install the access point in an area where structures, trees, or hills do not obstruct radio signals to and from the access point.•The access points can be installed at any height, but best throughput is achieved when all the access points are mounted at the same height. We recommend installing the access points no higher than 40 feet to allow support for wireless clients on the ground.Note To calculate path loss and to determine how far apart to install access points, consult an RF planning expert.Site SurveysEvery network application is a unique installation. Before installing multiple access points, you should perform a site survey to determine the optimum use of networking components and to maximize range, coverage, and network performance.Consider the following operating and environmental conditions when performing a site survey:•Data rates—Sensitivity and range are inversely proportional to data bit rates. The maximum radio range is achieved at the lowest workable data rate. A decrease in receiver sensitivity occurs as the radio data increases.•Antenna type and placement—Proper antenna configuration is a critical factor in maximizing radio range. As a general rule, range increases in proportion to antenna height. However, do not place the antenna higher than necessary, because the extra height also increases potential interference from other unlicensed radio systems and decreases the wireless coverage from the ground.•Physical environment—Clear or open areas provide better radio range than closed or filled areas.
2-9Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation GuideOL-24247-01Chapter 2 Installing the Access Point Installation Guidelines•Obstructions—Physical obstructions such as buildings, trees, or hills can hinder performance of wireless devices. Avoid locating the devices in a location where there is an obstruction between the sending and receiving antennas.Before Beginning the InstallationBefore you begin the installation process:•Ensure that a site survey has been performed.•Ensure that your network infrastructure devices are operational and properly configured.•Ensure that your controllers are connected to switch trunk ports.•Ensure that your switch is configured with untagged access ports for connecting your access points.•Ensure that a DHCP server with Option 43 configured is reachable by your access points, or manually configure the controller information in the access point (for additional information, refer to the “Configuring DHCP Option 43” section on page F-1).•Become familiar with the access point installation components (see the “Becoming Familiar with Access Point Installation Components” section on page 2-9).Becoming Familiar with Access Point Installation ComponentsThe access point is designed to be installed in an outdoor environment, such as the exterior roof overhang of a tall building or a streetlight pole. Carefully review the following figures to become familiar with the system components, connectors, indicators, cables, system interconnection, and grounding:•Components in a typical access point installation (see Figure 2-1)•Pole mount installation (see Figure 2-2)•Cable strand mount installation (see Figure 2-3•Streetlight power tap installation (see Figure 2-4)Note The illustrations in this document show all available connections for the access point. Unused connections are capped with a connector plug to ensure the watertight integrity of the access point. liquid-tight adapters are provided for connector openings, which can be installed before or after deploying the access point.
2-10Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation GuideOL-24247-01Chapter 2 Installing the Access Point Installation GuidelinesFigure 2-1 Components in a Typical Access Point InstallationNote The 1552 access point was designed with consideration for resistance to effects of lightning effects on the access point electronics. The 1552 access point employs lightning arrestor circuitry on the Ethernet and power ports. On the input Ethernet port, Gas Discharge Tubes (GDT) are used for the Power Entry Module (PEM) to mitigate lightning effect. On the AC power, GDTs are also used along with fuses to mitigate high-current condition. For the DC power, a fuse is used to mitigate high current condition.While not a common practice, the user may want to consider using lightning protection at the antenna ports for added protection. To meet EN/IEC60950-22 (Clause 4.2) requirements, the installer must ensure that additional protection is provided external to this equipment to reduce transient surges from Overvoltage IV to Overvoltage Category II at the AC power input of the access point. The over-voltage and fault-current protection components used to achieve this protection must comply with the IEC 61643 1Building roof-overhang 6Ground2Shielded outdoor-rated Ethernet(CAT5e or better) cable11.

To meet CAN/CSA-C22.2 No. 60950-22-07/UL60950-22 requirements, the installer may use alternative components to provide this additional protection. Those components may comply with ANSI/IEEE C62.11, CSA Certification Notice No. 516, CSA C22.2 No. 1, or UL 1449. Suitability of the components for the application must be determined for the intended installation. (For example, some devices are suitable for installation on the load side of the service entrance only, and some are suitable for use with cord-connected equipment only.)WarningInstallation of the equipment must comply with local and national electrical codes.

2-14Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation GuideOL-24247-01Chapter 2 Installing the Access Point Installation GuidelinesStep 5 Enter a description (32 characters maximum) of the access point in the Description field; for example, Fisher_Street_00.0B.91.21.3A.C7 shows the location and MAC address of the access point.Step 6 Choose an interface from the Interface Name pop-up menu, and click Apply.Step 7 Repeat Steps 2 to 6 to add other access points to the list.Step 8 Log out of your controller, and close your web browser.Configuring a RAP The access point defaults to the mesh access point (MAP) radio role. One or more of your access points must be reconfigured as a root access point (RAP). The RAPs connect to a wired Ethernet link through a switch to the controller. The MAPs use their wireless backhaul interface to connect to a RAP to reach the controller.To configure a RAP on the controller GUI, follow these steps:Step 1 Log into your controller using a web browser.Step 2 Click Wireless. When your access point associates to the controller, the name of the access point appears in the AP Name list.Step 3 Double-click your access point name. Step 4 Find Mesh Information, and choose Root AP by clicking the drop-down arrow in the AP Role field.Step 5 Click Apply.Step 6 Repeat Steps 2 through 5 for each RAP.Step 7 Log out from your controller, and close your web browser.Configuring a Bridge Group NameThe bridge group name (BGN) controls the association of the access points to a RAP. BGNs can be used to logically group the radios to avoid different networks on the same channel from communicating with each other. This setting is also useful if you have more than one RAP in your network in the same area.If you have two RAPs in your network in the same area (for more capacity), we recommend that you configure the two RAPs with the same BGN, but on different channels.The BGN is a string of ten characters maximum. A factory-set bridge group name (NULL VALUE) is assigned during manufacturing. It is not visible to you, but allows new access point radios to join a network of new access points. The BGN can be reconfigured from the Controller CLI and GUI. After configuring the BGN, the access point reboots.The BGN should be configured very carefully on a live network. You should always start from the farthest node (last node) from the RAP and move towards the RAP. If you start configuring the BGN in a different location, then the access points beyond this point (farther away) are dropped, as they have a different BGN.

2-21Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation GuideOL-24247-01Chapter 2 Installing the Access Point Installing the Access PointPole MountingThe access point can be installed where power is available, without the need for a wired LAN connection. The access point uses intelligent wireless routing that is based on the Adaptive Wireless Path Protocol (AWPP). AWPP enables a remote access point to dynamically optimize the best route to the wired LAN network using another access point. The 1522 access point uses the 5-GHz radio for the Mesh backhaul and connections. The 2.4-GHz radio is used for local wireless client access. To mount your access point on a vertical pole or streetlight pole, you need to install two metal bands around the pole to support the access point. This process requires extra tools and material not provided in the pole mount kit (see Table 2-2).To mount the access point onto a vertical pole or streetlight pole, follow these steps:Step 1 Select a mounting location on the pole to mount the access point. You can attach the access point to any pole from 2 to 16 inch (5.1 to 40.6 cm) in diameter.Note If you will be using a streetlight power tap adapter, position the access point within 3 ft (1 m) of the outdoor light control.Step 2 For poles larger than 3.5 inch (8.9 cm), mount the pole clamp bracket assembly to a pole (see Figure 2-10) using two metal straps. Following the instructions provided with the banding strap tool (BAND IT) (AIR-BAND-INST-TL=), loop each metal strap twice through the slots on the strap bracket.Caution Do not place the metal straps in the large open area between the pole clamp bracket and the strap brackets, because this does not properly secure the access point.Table 2-2 Material Needed to Mount Access Point on a Pole Mounting Method Materials Required In KitVertical or streetlight pole •Two 0.75-in (1.9 cm) stainless steel bands•Banding strap tool (BAND IT) (Cisco AIR-BAND-INST-TL=)•Ground lug (provided with access point)•Crimping tool for ground lug, Panduit CT-720 with CD-720-1 die (http://onlinecatalog.panduit.com) •#6 AWG ground wireYesNoYesNoNo

Secure any external connections that mate to this equipment by using screws, sliding latches, threaded connectors, or other means provided with this product. Substitution of components may impair suitability for Class I, Zone 2, Division 2. Statement 1062WarningIf you connect or disconnect the console cable with power applied to the unit or any device on the network, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding. To verify unit operation, perform POST on the device in a nonhazardous location before installation. Statement 1080WarningWhen installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046Removing the Access Point from ServiceWhen removing an access point from service, make sure you remove power from the access point before opening the cover and disconnecting the AC input wiring. When removing the AC wiring, the ground connection should be the last to be disconnected.Conducting Periodic InspectionsThe access point should be inspected periodically to ensure normal and airtight operation in the hazardous location environment. Table 2-5 lists the inspection routines and their periodicity.What to Do NextWhen you power up a MAP that is not connected to a wired Ethernet, fiber-optic, or cable network to the controller, the access point uses the Cisco Adaptive Wireless Path Protocol (AWPP) to bind to another mesh access point (MAP) with the best path to a root access point (RAP) connected to the wired network to a controller. The access point sends a discovery request when powered up. If you have configured the access point in the controller correctly, the controller sends back a discovery response to the access point. When that happens, the access point sends out a join request to the controller, and the controller responds with a join confirmation response. Then the access point establishes a Control And Provisioning of Wireless Access Points (CAPWAP) connection to the controller and gets the shared secret configured on the controller. Refer to the Cisco Wireless LAN Controller Configuration Guide for more information on configuring, monitoring, and operating your access points.
