About This Guide xii Chapter 1 Meru Access Points and Radio Switch Meru 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 sites 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. Meru AP Introducing the Radio Switch RS4000 The 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 2007 Meru Networks, Inc. Meru Access Points and Radio Switch 1 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-Fidedicated 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). POWER RADIO I RADIO II ETHERNET 8 7 1 0 0 Figure 1: Radio Switch RS4000 2007 Meru Networks, Inc. Meru Access Points and Radio Switch 2 RS4000 Hardware Features and Specifications The 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. 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. 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.

Ensure your network supports the full breadth of wireless LAN clients with Meru Access Points. Dual 802.11b/g and 802.11a software programmable radios Simultaneously support 802.11b, 802.11g and 802.11a clients Introducing the Meru Access Point AP200 Series The Meru Access Point AP200 series provides two models that conform to the speci-

fications provided by the IEEE 802.11a and 802.11g protocols and provide backward compatibility for the 802.11b protocol. An AP200 works with most standard Wi-Fi clients.

The AP201 houses a single 802.11a/b/g radio device

The AP208 supports a maximum of two radio devices that can simultaneously run two protocols (802.11b, g or b/g on interface 1 and 802.11a on interface 2). Alternately the second radio can be configured to run as an RF monitor to the Meru Controller, providing real-time status of RF activity to optimize the wireless network. The Meru Access Point AP200 series (referred hereafter as the AP200, unless specif-

ically referring to the AP201 or AP208) is housed in a metal case with a plastic remov-

able cover. As such, it can be used for plenum installations when the plastic cover is removed. 2007 Meru Networks, Inc. Meru Access Points and Radio Switch 5 AP200 9 0 1 0 0 Figure 2: Access Point AP200 Introducing the Meru Access Point AP150 Series Note:

Mounting bracket About an Hoffman/NEMA Enclosure Installation The 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. Caution!

Laboratories. This method of mounting has not been evaluated by Underwriters 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 12 Meru Access Point and Radio Switch Installation Guide 2007 Meru Networks, Inc. Installation Requirements Cable Pass-through Holes in the NEMA Enclosure on page 25. To install in the Hoffman/NEMA Enclosure, see the section Hoffman/NEMA Enclosure RS4000 Instal-

lation on page 25. NEMA box Attach to wall with 4 screws 7 8 1 0 0 Figure 5: Open NEMA Box Showing Mounting Holes Optimum Antenna Positioning and Placement Warning! 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. 2007 Meru Networks, Inc.

The bracket also allows for junction box mounting. The RS4000 has a security cable slot so you can secure the RS4000 with a Note:

standard security cable (for example, Kensington cable locks), such as are used to secure laptop computers. To wall mount an RS4000:

1. Remove the bracket from back side the RS4000, if it is attached, by unscrewing each of the 4 knurled thumbscrews (see Figure 6). 14 Meru Access Point and Radio Switch Installation Guide 2007 Meru Networks, Inc. Installing the RS4000 Figure 6: Bracket Attached to RS4000 2. Choose the location on the wall where the RS4000 will be mounted. The RS4000 can be oriented in any direction, but it is probably more convenient if the SMA antenna mounts are at the top. This orientation is more convenient for reading LED status. 3. Using the bracket holes as a template, mark the location on the wall for the two RS4000 bracket mounting screws. They are placed 5 25/32" (147mm) apart, center-to-center, one above the other. If you are not using plastic wall anchors, you must center the mounting screws on a wall stud. Note:

The RS4000 mounting bracket provides holes to accommodate many types of common installations such as over a junction box, etc. This procedure describes only the standard wall mount. 4. Drill holes at the locations you marked:

3/16-inch holes if you are using plastic anchors 1/8-inch holes if you are using only the screws If you are using plastic anchors, install them in the holes. 5. 2007 Meru Networks, Inc.

Hoffman/NEMA Enclosure RS4000 Installation Use the procedures in this section to mount the RS4000 within the Hoffman or NEMA enclosure. It will be necessary to modify the NEMA enclosure by drilling cable pass-

through holes before installing the RS4000. The recommended Meru installation is a vertical wall mount, which allows for Note:

unimpeded air flow through the unit. The option to install the RS4000 within a Hoffman/NEMA enclosure is left to the customers 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. Creating Cable Pass-through Holes in the NEMA Enclosure To 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. 2007 Meru Networks, Inc.

Power over Ethernet (PoE) connection to the network switch servicing the controller. APs can obtain their power from 802.3af standard Power over Ethernet (PoE)-compat-

ible network switch or PoE power injector installed between the switch and the AP200. Select a location with minimal physical obstructions between the AP and the wireless stations. In an office with cubicles, mounting the APs below a hanging ceiling or the wall near the ceiling provides the least obstructed communications path. For an external power supply connection, ensure the power source is near to where the AP200 will be mounted. 34 Meru Access Point and Radio Switch Installation Guide 2007 Meru Networks, Inc. Installing the Access Points Most installations receive the best coverage using the following guidelines:

Install APs toward the center of the building.

Do not install APs near metal objects, such as heating ducts, metal doors, or electric service panels.

Relative to the ground, orient the antenna up or down, not sideways. Note:

environment. Place access points accordingly. The previous guidelines are general guidelines. Each site has its own unique 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 Antennas The 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. 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. Mounting the Access Point You can mount an AP200 in the following ways:

Each site has its own unique 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 Antennas The 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. 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. Mounting the Access Point You can mount an AP150 in the following ways:

Horizontally, as described in the Horizontal Mounting section.

Vertically, as described in the Vertical Mounting with the Mounting Bracket section.

Below a hanging ceiling, as described in the Mounting Below a Suspended Ceiling section. Horizontal Mounting To 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. 2007 Meru Networks, Inc.

Network configuration 2007 Meru Networks, Inc. About This Guide xi 2007 Meru Networks, Inc. About This Guide xii Chapter 1 Meru Access Points and Radio Switch Meru 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 sites 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. Meru AP Introducing the Radio Switch RS4000 The 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 2007 Meru Networks, Inc. Meru Access Points and Radio Switch 1 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-Fidedicated 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).

Meru Access Points and Radio Switch 2 RS4000 Hardware Features and Specifications The 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. 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. 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.

Mounting bracket About an Hoffman/NEMA Enclosure Installation The 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. Caution!

Laboratories. This method of mounting has not been evaluated by Underwriters 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 12 Meru Access Point and Radio Switch Installation Guide 2007 Meru Networks, Inc.

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. 2007 Meru Networks, Inc.

Hoffman/NEMA Enclosure RS4000 Installation Use the procedures in this section to mount the RS4000 within the Hoffman or NEMA enclosure. It will be necessary to modify the NEMA enclosure by drilling cable pass-

through holes before installing the RS4000. The recommended Meru installation is a vertical wall mount, which allows for Note:

unimpeded air flow through the unit. The option to install the RS4000 within a Hoffman/NEMA enclosure is left to the customers 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. Creating Cable Pass-through Holes in the NEMA Enclosure To 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. 2007 Meru Networks, Inc.

Relatively unobstructed access to the stations the AP serves

Power over Ethernet (PoE) connection to the network switch servicing the controller. APs can obtain their power from 802.3af standard Power over Ethernet (PoE)-compat-

ible network switch or PoE power injector installed between the switch and the AP200. Select a location with minimal physical obstructions between the AP and the wireless stations. In an office with cubicles, mounting the APs below a hanging ceiling or the wall near the ceiling provides the least obstructed communications path. For an external power supply connection, ensure the power source is near to where the AP200 will be mounted. 34 Meru Access Point and Radio Switch Installation Guide 2007 Meru Networks, Inc. Installing the Access Points Most installations receive the best coverage using the following guidelines:

Install APs toward the center of the building.

Do not install APs near metal objects, such as heating ducts, metal doors, or electric service panels.

Each site has its own unique 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 Antennas The 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. 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. Mounting the Access Point You can mount an AP200 in the following ways:

The radiated output power of the Meru Networks devices is well below the FCC radio frequency exposure limits. However, the Meru Access Points should be used in such a manner that the potential for human contact dur-

ing normal operation is minimized. When installing and operating these devices, keep a minimum distance of 20 cm (8 inches) between the anten-

nas and any persons/users in the vicinity. Radio Frequency Interference Requirements Interference Statement Note:

Meru Access Point These devices are restricted to indoor use because they operate in the 5.15 to 5.25 GHz frequency range. The FCC requires such products to be used indoors for the frequency range 5.15 GHz to 5.25 GHz to reduce the potential for harmful interference to co-channel Mobile Satellite systems. These devices comply with Part 15 of the FCC Rules. Operation of the devices is subject to the following two conditions: (1) The devices may not cause harmful inter-

ference, and (2) The devices must accept any interference that may cause undesired operation. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installa-

tion. This equipment generates, uses, and can radiate radio frequency energy. If the equipment is not installed and used in accordance with the instructions, the equip-

ment may cause harmful interference to radio communications. There is no guar-

antee, however, that such interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception

(which can be determined by turning the equipment off and on), the user is encour-

aged to try to correct the interference by taking one or more of the following measures:

Relocate this device.

Increase the separation between the device and the receiver.
