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 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. 2008 Meru Networks, Inc. Meru Access Points and Radio Switch 6 Internal Use OnlyBeta Draft 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 5: Radio Switch RS4000 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. 2008 Meru Networks, Inc. Meru Access Points and Radio Switch 7 Internal Use OnlyBeta Draft

. 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

connected equipment's associated LAN connection. In addition, the AP300 should be mounted in a loca-

tion that meets the following conditions:

Relatively unobstructed access to the stations the AP serves. 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 (plenum is supported) 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 AP300 will be mounted.

Access to wall outlet or a to a Power over Ethernet (PoE) connection to the network switch servicing the controller. 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 Attach the Antennas The AP320, AP311, and AP302 have six external antenna ports, labeled 1 - 6.

LAN Switch Power Injector AC Power External Antenna Indoor Outdoor RF Coaxial Cable OAP 180 Ethernet Cable Ground Wire 6 9 1 0 0 Figure 27: Sample Physical Layout Radio Position Planning Never construct a radio mast, pole, or tower near overhead power lines. In addition, local regulations may limit or prevent construction of a high radio mast or tower. If your OAP180 link requires a high radio mast or tower, consult a professional contractor for advice. Once the required antenna height has been determined, other factors affecting the precise position of the OAP180 must be considered.

Be sure there are no other radio antennas within 2 m (6 ft.) of the OAP180.

Place the OAP180 away from power and telephone lines.

Avoid placing the OAP180 too close to any metallic, reflective surfaces, such as roof-

installed air-conditioning equipment, tinted windows, wire fences, or water pipes. Radio Interference Avoiding radio interference is an important part of wireless planning. Interference is caused by other radio transmissions using the same or an adjacent channel frequency. You should first scan your proposed site using a spectrum analyzer to determine if there are 2008 Meru Networks, Inc. Installing the OAP180 47 Installing the Access Points any strong radio signals using the 802.11a or 802.11bg channel frequencies. Always use a channel frequency that is furthest away from another signal. Weather Conditions Take into account any extreme weather conditions that are known to affect your loca-

tion. Consider these factors:

Temperature The OAP180 is tested for normal operation in temperatures from - 40F to 140F. Operating in temperatures outside of this range may cause the unit to fail.

Wind Velocity The OAP180 can operate in winds up to 44 m/s and survive higher wind speeds up to 66 m/s. You must consider the known maximum wind velocity and direction at the site and be sure that any supporting structure, such as a pole, mast, or tower, is built to withstand this force.

Lightning The OAP180 includes its own built-in lightning surge protection. However, you should make sure that the unit, any supporting structure, and cables are all properly grounded. Additional protection using lightning rods, lightning arrestors, or surge suppressors may also be employed. Antenna sockets should point upwards in a vertical manner

Rain The OAP180 is weatherproofed against rain. Also, prolonged heavy rain has no significant effect on the radio signal. However, it is recommended to apply weatherproof sealing tape around the Ethernet port and antenna connectors for extra protection. If moisture enters a connector, it may cause a degradation in performance or even a complete failure of the link.

Snow and Ice Falling snow, like rain, has no significant effect on the radio signal. However, a build up of snow or ice on antennas may cause the link to fail. In this case, the snow or ice has to be cleared from the antennas to restore operation of the link. Ethernet Cabling When a suitable antenna location has been determined, plan a cable route from the OAP180 outdoors to the power injector module indoors. Consider these points:

The Ethernet cable length should never be longer than 100 ft.

Determine a building entry point for the cable.

Determine if conduits, bracing, or other structures are required for safety or protection of the cable.

For lightning protection at the power injector end of the cable, consider using a lightning arrestor immediately before the cable enters the building.

The shield of the ethernet cable needs to be grounded at the lightning arrestor. If, by design, the lightning arrestor cannot provide this ground, the shield of the ethernet cable will need to be grounded by the installer. 48 Meru Access Point and Radio Switch Installation Guide 2008 Meru Networks, Inc. Installing the Access Points Grounding It is important that the OAP180, cables, and any supporting structures are properly grounded. The OAP180 unit includes a grounding screw to attach a ground wire. Be sure that grounding is available and that it meets local and national electrical codes. Test Basic Link Operation Set up the OAP180 on the ground, either outdoors or indoors. Connect the unit as indi-

cated in this document and perform the basic configuration tasks outlined below. When you are satisfied that the OAP180 is operating correctly, proceed to mounting the unit in the intended location. Mounting the Access Point The OAP180 can be mounted on the following (brackets are included):

Align Antenna After the OAP180 unit is mounted, connected, and the radios are operating, the anten-

nas must be accurately aligned to ensure optimum performance of the OAP180 links. In 54 Meru Access Point and Radio Switch Installation Guide 2008 Meru Networks, Inc. this point-to-multipoint configuration all OAP180 nodes must be aligned with the root OAP180 antenna.

The 11a connection LED blinks green when radio packets are being transmitted and when the radio is beaconing. If there is traffic over the air on this radio, the blinking rate increases. Ethernet The Ethernet Link LED blinks green when a link has been detected and is in use. Antenna Gain Recommendations The OAP180 auto-adjusts the power level sent from the radio to the antenna, so that the EIRP emitted from the antenna is the value defined by the controller (100mW by default). You can increase this setting if you are compensating for signal loss from long inexpensive cables connecting external antennas. (Configure a false/low dBi antenna gain to trick the radio into supplying more transmit power to that antenna, which would then make up for the cable loss.) You may also need to decrease the EIRP from 100mW to 30mW for a device that only transmits at 30mW. The Antenna Gain values can be changed from the Web UI Configuration>APs>Antenna Properties view, or from the CLI using the antenna-

property command. Determine the appropriate gain for your antenna by checking the following chart. 56 Meru Access Point and Radio Switch Installation Guide 2008 Meru Networks, Inc. Checking LED Activity Table 12: Antenna Gain Antenna MN-ACC-ANT-BG08O-NM 802.11 b/g 8 dBi Omni-

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.

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 76 Meru Access Point and Radio Switch Installation Guide 2008 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. 2008 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. 2008 Meru Networks, Inc.

RS4000 2008 Meru Networks, Inc. Regulatory Information 117 Internal Use OnlyBeta Draft USA Interference Statement Note:

Meru Access Points 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. High-power radars are allocated as primary users of the 5.25 to 5.35 GHz and 5.65 to 5.85 GHz bands. These radar stations can cause interference with or damage to these devices, or both. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and

(2) this device must accept any interference received, including 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:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and receiver.

Connect the equipment into an outlet on a circuit different from to which the receiver is connected.

Consult the dealer or an experienced radio/TV technician for help. Note:

The Meru Access Point must be installed and used in strict accordance with the manufacturers instructions as described in the user documenta-

tion that comes with the product. Any other installation or use may violate FCC Part 15 regulations. Modifications not expressly approved by Meru Networks, Inc. could void your authority to operate the equipment. This device must not be co-located or operating in conjunction with any other antenna or transmitter. For products available in the USA and Canadian markets, only channels 1 through 11 can be operated. Selection of other channels is not authorized. 118 Meru Access Point and Radio Switch Installation Guide 2008 Meru Networks, Inc. Internal Use OnlyBeta Draft Canada. Industry Canada (IC) Canada. Industry Canada (IC) The Class B digital portion of this apparatus complies with Canadian standard ICES-

003. These devices comply with RSS210 of Industry Canada. Per RSS 210 A9.5 point 7:

(i) the device for the band 5150-5250 MHz is only for indoor usage to reduce potential for harmful interference to co-channel mobile satellite systems;

(ii) the maximum antenna gain permitted (for devices in the bands 5250-5350 MHz and 5470-5725 MHz) to comply with the e.i.r.p. limit; and

(iii) the maximum antenna gain permitted (for devices in the band 5725-5825 MHz) to comply with the e.i.r.p. limits specified for point-to-point and non point-to-point operation as appropriate, as stated in section A9.2(3). In addition, users should also be cautioned to take note that high-power radars are allocated as primary users (meaning they have priority) of the bands 5250-5350 MHz and 5650-5850 MHz and these radars could cause interference and/or damage to LE-

LAN devices.

(iv) These devices are not permitted to operate in the 5600 - 5650 MHz band. For products available in the USA and Canadian markets, only channels 1 through 11 can be operated. Selection of other channels is not authorized. Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interfer-

ence that may cause undesired operation of this device. This device and its listed antenna(s) must not be co-located or operated in conjunc-

tion with any other antenna or transmitter Lutilisation de ce dispositif est autorise seulement aux conditions suivantes: (1) il ne doit pas produire de brouillage et (2) lutilisateur du dispositif doit tre prt accepter tout brouillage radiolectrique reu, mme si ce brouillage est susceptible de compromettre le fonctionnement du dispositif. The term "IC" before the equipment certification number only signifies that the Industry Canada technical specifications were met. To reduce the potential radio interference to other users, the antenna type and gain should be chosen so that the equivalent isotropically radiated power (EIRP) is not more than that required for successful communication. To prevent radio interference to the licensed service, this device is intended to be operated indoors and away from windows to provide maximum shielding. Equipment

(or its transmit antenna) that is installed outdoors is subject to licensing. Pour empecher que cet appareil cause du brouillage au service faisant lobjet dune licence, il doit etre utilze a linterieur et devrait etre place lin des fenetres afin de Fournier un ecram de blindage maximal. Si le matriel (ou son antenne demission) est installe a lexterieur, il doit faire lobjet dune licence. 2008 Meru Networks, Inc. Regulatory Information 119 Internal Use OnlyBeta Draft Canada.
