Meru Access Points and Radio Switch 1 Chapter 1Meru Access Points and Radio SwitchMeru Access Points and Radio Switches contain radio devices that communicate with the Meru Controller and form the wireless LAN (WLAN). The Meru Controller, Radio Switches, and Access Points connect to the site’s wired LAN through wired switches. Wireless clients associate with the Radio Switches and Access Points as they roam throughout the WLAN. As such, the Meru Wireless LAN System is an extension of the wired LAN, providing the wireless benefits of client mobility, enhanced access, and dynamic network configuration. Introducing the Radio Switch RS4000The Radio Switch RS4000 enables high-capacity enterprise-class wireless LAN connec-tivity with full support of standard 802.11 security and network management features. Each RS4000 contains four 802.11 radios (two 802.11b/g, two 802.11a) for high data and voice throughput – an essential requirement for high user-density envi-ronments with several simultaneous users. Classrooms and convention halls are typical deployment applications of the Radio Switch. Deploying the Radio Switch is Meru AP
© 2007 Meru Networks, Inc. Meru Access Points and Radio Switch 2 easy— as with wireless access points, the Radio Switch can be installed wherever wireless coverage is needed. For large buildings with multiple rooms and floors, more than one Radio Switch can be installed to cover the desired area. Wireless users can seamlessly roam from one Radio Switch to another, getting high-capacity WLAN access throughout the wireless enterprise enabled with multiple Radio Switches. The RS4000 also balances radio traffic across its RF channels and resolves contention within each RF channel such that users receive a switched wireless experience with dedicated bandwidth to execute a variety of applications ranging from web browsing and VoIP mobility to multimedia streaming.The RS4000 ships with either a high-gain omni-directional indoor antenna or a 180-degree directional indoor antenna that aggregates and layers radio transmissions from each of the built-in radios. The antenna can broadcast every channel available to blanket the area around the Radio Switch, yet avoid interference and contention. This simplifies deployment efforts by eliminating the need for additional antennas for each radio. More importantly, RF channel planning efforts are greatly simplified. Using the RS4000, wireless users experience the benefits of switching technology on Wi-Fi—dedicated bandwidth, traffic separation, and multi-service network support. The RS4000 can be deployed with up to two 802.11b/g and two 802.11a channels active on the radio interfaces. The 802.11b/g channels must be separated by a minimum of 8 channels (for example, channels 1 and 9), so the recommended set is channels 1 and 11, typically. The 802.11a channels must be separated by a minimum of 80MHz/16 channels for best performance (for example, channels 36 and 52).Figure 1: Radio Switch RS4000POWERRADIO IRADIO IIETHERNET00178

Meru Access Points and Radio Switch 3 RS4000 Hardware Features and SpecificationsThe RS4000 has four 802.11 radios (two 802.11a and two 802.11bg) that transmit and receive simultaneously on four different channels to increase the total available wireless bandwidth at a given area. The RS4000 connects to the LAN using one 10/100 Mbps Ethernet connection for each radio pair. The RS4000 is powered using two IEEE 802.3af POE connections, each with 15W power. .The RS4000 works in conjunction with a wideband RF combination omni directional (WRC/OD) indoor antenna or a 180-degree directional indoor antenna. Only one antenna is needed for simultaneous operation of all radios of an RS4000 in both the 2.4GHz and 5GHz bands. The antenna must be connected to the Radio Switch using any one of the low-loss antenna cables provided in the antenna packaging.The following table lists the key hardware features of the RS4000.Note:PoE must be provided on the first Ethernet connector (ETH1); the antenna cannot operate correctly without that power source. Power to the second Ethernet connector (ETH2 ) is optional; if not connected, two of the radios will not operate.Table 1: RS4000 Hardware FeaturesFeature Description802.11 Connectivity Two 802.11b/g radios (2.4GHz)Two 802.11a radios (5 GHz)Ethernet Connectivity Two auto-sensing 10/100 Mbps ports, one for each radio pairPowerProvided by two 802.3af POE connec-tions, one for each radio pair (15W per connector)LEDs Power, Radio Activity, and Ethernet Activity LEDs per radioDimensions 9.5" x 8.5" x 3.875"

Installation Requirements © 2007 Meru Networks, Inc. Installing the RS4000 11 The RS4000 obtains power from 802.3af standard Power over Ethernet (PoE)-compat-ible network switch or PoE power injector installed between the switch and the RS4000. At least one PoE connection must be connected.Select a location with minimal physical obstructions between the RS4000 antenna and the wireless stations. In many cases, mounting the RS4000 antenna on the wall near the ceiling provides the least obstructed communications path. Most installations receive the best coverage using the following guidelines:zDo not install the antenna near metal objects, such as heating ducts, metal doors, or electric service panels.zRelative to the ground, orient the antenna up or down, not sideways.The RS4000 is only intended for installation in Environment A as defined in IEEE 802.3af. All interconnected equipment must be contained within the same building, including the interconnected equipment's associated LAN connection.Note:The previous guidelines are general guidelines. Each site has its own unique environment. Place antenna accordingly.
12 Meru Access Point and Radio Switch Installation Guide © 2007 Meru Networks, Inc.Installation Requirements You need the tools listed in Tab le 2 .Table 2: RS4000 Installation ToolsAbout an Hoffman/NEMA Enclosure InstallationThe recommended RS4000 installation is a wall mount, but if necessary the RS4000 can be housed inside a protective NEMA or Hoffman box that is manufactured with external corner tabs for standard wall mounting, above or below a ceiling. When installing in the Hoffman/NEMA box, the RS4000 attaches to an optional Hoffman/NEMA box mounting plate, which replaces the standard wall mount bracket.Meru leaves the placement and orientation of the Hoffman/NEMA enclosure to the customer. It will be necessary to drill holes through the plastic NEMA enclosure with a Meru-provided template to enable the antenna and Ethernet cabling to exit the enclosure. Instructions for performing this task are provided in the section “Creating Installation Type Tools RequiredVertical mounting over a wall studzDrill z1/8"drill bitzScrewdriverz(Optional) PliersVertical mounting on sheetrockzDrillz3/16" drill bitzScrewdriverz(Optional) PliersHorizontal mounting below a hanging ceilingzTwo caddy fastenerszTwo plastic spacerszTwo keps nuts (with attached lock washer)zMounting bracketMounting above a ceiling tilezTwo T-ra i l cl i p szOne T-box hangerzOne bracket mounting clipzMounting bracketCaution!This method of mounting has not been evaluated by Underwriters Laboratories.

To install in the Hoffman/NEMA Enclosure, see the section “Hoffman/NEMA Enclosure RS4000 Instal-lation” on page 25.Figure 5: Open NEMA Box Showing Mounting HolesOptimum Antenna Positioning and Placement00187NEMA boxAttach to wall with 4 screwsWarning! Inside antennas must be positioned to observe minimum separation of 20 cm. (~ 8 in.) from all users and bystanders. For the protection of personnel working in the vicinity of inside (downlink) antennas, the following guidelines for minimum distances between the human body and the antenna must be observed. The installation of the indoor antenna must be such that, under normal conditions, all personnel cannot come within 20 cm. (~ 8.0 in.) from any inside antenna. Exceeding this minimum separation will ensure that the employee or bystander does not receive RF-exposure beyond the Maximum Permissible Exposure according to FCC CFR 47, section 1.1310 i.e. limits for General Population/Uncontrolled Exposure.

It will be necessary to modify the NEMA enclosure by drilling cable pass-through holes before installing the RS4000.Creating Cable Pass-through Holes in the NEMA EnclosureTo create cable pass-through holes in the NEMA enclosure, Meru supplies a template with markings that coincide with the placement of the Ethernet and antenna cable locations on the RS4000. Depending on the orientation of the RS4000 installation in the NEMA enclosure, the template is to be used on the side of the enclosure adjacent to the RS4000 top panel, where the cables connect.1. Open the lid of the empty NEMA enclosure to provide unimpeded access to the enclosure sides.2. On the outside of the empty NEMA enclosure, locate the top center of the side where the cables will exit.3. Using the pattern on the supplied template, mark the center of the holes and drill a 1/2" to 1" hole at each of the three locations specified by the template.Note:The recommended Meru installation is a vertical wall mount, which allows for unimpeded air flow through the unit. The option to install the RS4000 within a Hoffman/NEMA enclosure is left to the customer’s discretion, based on site-specific factors such as protection and accessibility, etc. Installation in the Hoffman enclosure requires drilling air vents and cable pass-through holes.

Installing the Access Points © 2007 Meru Networks, Inc. Installing the AP200 35 Most installations receive the best coverage using the following guidelines:Install APs toward the center of the building.zDo not install APs near metal objects, such as heating ducts, metal doors, or electric service panels.zRelative to the ground, orient the antenna up or down, not sideways.The AP200 is only intended for installation in Environment A as defined in IEEE 802.3af. All interconnected equipment must be contained within the same building, including the interconnected equipment's associated LAN connection.Attaching the AP200 AntennasThe AP200 is provided with external antenna ports. Make sure that all external antennas and their associated wiring are located entirely indoors. The external antennas are not suitable for outside use.If the AP200 does not have external antennas, attach the antennas to the connectors on the AP200 (see Figure 21). Rotate the knurled ring at the base of the antenna clockwise to attach the antenna. The ring should be finger-tight.Mounting the Access PointYou can mount an AP200 in the following ways:zHorizontally, as described in the “Horizontal Mounting” section.zVertically, as described in the “Vertical Mounting” section.zBelow a hanging ceiling, as described in the “Mounting Below a Suspended Ceiling” section.zAbove a tiled hanging ceiling, as described in the “Mounting Above a Suspended Ceiling” section.Note:The previous guidelines are general guidelines. Each site has its own unique environment. Place access points accordingly.Caution!When changing the orientation of the antennas, be sure to slightly loosen the knurled ring before moving the antenna. Retighten the ring afterward. Otherwise, you might damage the internal cabling in the AP.

Installing the Access Points © 2007 Meru Networks, Inc. Installing the AP150 51 Most installations receive the best coverage using the following guidelines:Install APs toward the center of the building.zDo not install APs near metal objects, such as heating ducts, metal doors, or electric service panels.zRelative to the ground, orient the antenna up or down, not sideways.The AP150 is only intended for installation in Environment A as defined in IEEE 802.3af. All interconnected equipment must be contained within the same building, including the interconnected equipment's associated LAN connection.Attaching the AP150 AntennasThe AP150 is provided with external antenna ports. Make sure that all external antennas and their associated wiring are located entirely indoors. The external antennas are not suitable for outside use.If the AP150 does not have external antennas, attach the antennas to the connectors on the AP150 (see Figure 33). Rotate the knurled ring at the base of the antenna clockwise to attach the antenna. The ring should be finger-tight.Mounting the Access PointYou can mount an AP150 in the following ways:zHorizontally, as described in the “Horizontal Mounting” section.zVertically, as described in the “Vertical Mounting with the Mounting Bracket” section.zBelow a hanging ceiling, as described in the “Mounting Below a Suspended Ceiling” section.Horizontal MountingTo horizontally mount an AP150:1. Place the AP150 flat on the horizontal surface.2. For each antenna, loosen the knurled ring at the base of the antenna (see Figure 33), point the antenna straight up, then retighten the ring.Note:The previous guidelines are general guidelines. Each site has its own unique environment. Place access points accordingly.Caution!When changing the orientation of the antennas, be sure to slightly loosen the knurled ring before moving the antenna. Retighten the ring afterward. Otherwise, you might damage the internal cabling in the AP.
