802.3af compliant PoE device (for 2x2 mode)

802.3at compliant PoE device (needed for 3x3 mode) Install the Access Points Select a Location The AP300 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 inter-

connected equipment's associated LAN connection. In addition, the AP300 should be mounted in a location 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 testing is not complete at this time) 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. 2007 Meru Networks, Inc. Installing the AP300 7 Install the Access Points

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 AP300 Antennas The AP300 has six external antenna ports, labeled 1 - 6. AP320 and AP311 use all six antennas. AP310 uses three antennas (1 - 3). Make sure that all external antennas and their associated wiring are located entirely indoors. The external antennas are not suitable for outside use. 5 6 3 4 R F 2 R F 1 L A N A 2 A 2 2 A 2 1 7 0 2 0 0 Figure 4: AP320 Antennas 1-6 Attach Standard Antennas All standard attached antennas must be the same model. If you replace one antenna, replace them all. These antennas are supported:

Antenna Standard multiband, omni-directional white antenna (included)

Standard Antenna Gain ~ 2.2 dBi for 2.4 GHz,and 3 dBi for 5 GHz

RP SMA connectors for external antenna options Make sure that all external antennas and their associated wiring are located entirely indoors. The external antennas shipped are not suitable for outside use. 8 Meru AP300 Guide 2007 Meru Networks, Inc. Attach the antennas to the connectors on the AP300 (see Figure 5). Rotate the knurled ring at the base of the antenna clockwise to attach the antenna. The ring should be finger-tight. Install the Access Points antenna connector Figure 5: AP300 Antenna Connection 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. Attach Remote Antennas Remote antenna testing is not complete at this time. Mount the Access Point You can mount an AP300 in the following ways:

Horizontally on a surface, for example set the AP300 on a shelf

Vertically on a wall

In the ceiling (plenum testing is not complete at this time) Mount AP300 Horizontally When mounting an AP300 horizontally, remove the mounting bracket. Be sure to position the antennas vertically when an AP300 sits on a surface. See Figure 6. 2007 Meru Networks, Inc. Installing the AP300 9 Install the Access Points R F 2 R F 1 L A N A 2 A 2 A 2 7 0 2 0 0 Figure 6: Horizontal AP300 Mount AP300 on a Wall Note:

If you are replacing AP150s, you can use the existing brackets: the AP150 and AP300 use the same bracket. If you are replacing AP200s, the AP300 bracket can be attached to the old bracket with shoulder screws (see Appendix A); you dont have to remove the old brackets. The AP300 ships with the mounting bracket attached. To mount an AP300 on a wall:

1. Using the bracket holes as a guide, mark the location on the wall for the two AP bracket mounting screws. If possible, center the mounting screws on a wall stud. If you do not center the mounting screws on a wall stud, use plastic wall anchors. 2. 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. 3. 4. Screw in the screws most of the way. 5. Mount the bracket on the screws, placing the circular portion of the keyhole mounts over the screw heads and sliding the bracket down. 6. Connect one end of the Ethernet cable to the AP300 Ethernet port shown in Figure 7. 10 Meru AP300 Guide 2007 Meru Networks, Inc. Check AP300 LED Activity A 5 CON LAN Ethernet Port A 6 5V DC 9 0 2 0 0 Figure 7: Connect AP300 to LAN 7.

The default power source is 802.3af, and the default channel width is 20 MHz; these are the lowest (and slowest) settings. Increase range and throughput by changing MIMO mode to 3x3. The power supply option that you select determines whether or not you can use 3x3 MIMO. Be sure to change the power supply setting to either a DC power supply (provided) or a 802.11at PoE before changing MIMO mode to 3x3. Configure AP300 Using the CLI Use the CLI command configure ap to set the Power Supply Type and configure interface Dot11Radio to set the Channel Width, and MIMO Mode. For example:

1. Access the controller from a browser by entering the IP address of the controller. 2. Switch to configuration mode by entering terminal configuration at the CLI prompt. The prompt changes to controller name (config). 3. Select an AP by entering the command ap #. For example:

1. Enter the IP address of the controller in your browser. You see the controller GUI interface. 2. From the controller GUI, click Configuration > Devices > APs. The AP Table shown in Figure 9 is displayed. 14 Meru AP300 Guide 2007 Meru Networks, Inc. Configure AP300 Software Figure 9: AP Table Configuration Window 3. Click the arrow that corresponds to the AP300 to change. The AP configuration for that AP is displayed. See Figure 10. Figure 10: Changing Power Supply Type 4. Click the Power Supply Type drop-down list and select one of the following options. The included DC power block corresponds to the option 5V DC. 2007 Meru Networks, Inc. Installing the AP300 15 Configure AP300 Software 802.3-af: Default power supply. Select this when using a traditional PoE. This power supply type only supports 2x2 MIMO mode. 802.3-at: Select when using a higher-powered, next generation PoE. This power supply type supports 3x3 MIMO mode. 5V-DC: Select when AP300 is plugged into a wall outlet. This power supply type supports 3x3 MIMO mode. dual-802.3: Select when using a dongle that combines power from two traditional PoEs. This power supply type supports 3x3 MIMO mode. 5. Click OK. 6. Next, configure MIMO mode and Channel Width. Click the Wireless Interface tab. You see the Wireless Interface Configuration window shown in Figure 11. Figure 11: Wireless Interface Tab - Set MIMO Mode and Channel Width Note:

The Short Preamble Setting affects 11b clients only. The Protection Mechanism setting has no effect at this time. 7. Configure RF Band Selection by selecting a value from the drop-down list. To configure the band as N only, select a setting that includes N and change the data rates setting to make only N viable. 8. Configure MIMO mode by clicking the drop-down list and selecting either 2x2 or 3x3. Be sure you have already configured an appropriate power source for 3x3 MIMO Mode. 3x3 MIMO Mode produces higher reliability, range, and speed but both settings (2x2 and 3x3) should approach 320 mbps. 16 Meru AP300 Guide 2007 Meru Networks, Inc. Troubleshooting 9. Configure Channel Width by clicking the drop-down list and selecting either 40 MHz Extension channel above or 40 MHz Extension channel below. The channel above and channel below are relative to the value set in the Channel control setting (see Figure 11, the third setting from the top). This configures the channel bonding. 10. Click OK. Troubleshooting

If an AP320 continually reboots or demonstrates other unusual behavior, and MIMO Mode is set to 3x3, there may be a mismatch of power and MIMO Mode. Make sure that you have an appropriate power source configured, as well as attached to an AP320 with MIMO Mode set to 3x3.

When RF band selection is set to 802.11n, the security mode can only be set at clear, wpa2 or wpa2psk. This is an 802.11n restriction.

The ChannelWidth field value 40 Mhz-extension-channel-above is only applicable if the extension channel above is available in the country code.

Meru Access Points (APs) must be installed and used in strict accordance with the manufacturers instructions as described in the user documen-

tation that comes with the product. For country-specific approvals, see below. Meru Networks, Inc. is not responsible for any radio or television interference caused by unauthorized modification of APs, or the substitution or attachment of connecting cables and equipment other than that specified by Meru Networks, Inc. The correc-

tion of interference caused by such unauthorized modification, substitution or attachment is the responsibility of the user. Meru Networks, Inc. and its authorized resellers or distributors are not liable for any damage or violation of government regulations that may arise from the user failing to comply with these guidelines. USA Federal Communications Commission

(FCC) FCC Radiation Exposure Statement Caution! The radiated output power of the Meru Networks, Inc. devices is well below the FCC radio frequency exposure limits. However, the Meru Net-

works, Inc. Meru Access Points should be used in such a manner that the potential for human contact during normal operation is minimized. To avoid the possibility of exceeding the FCC radio frequency exposure limits, you should keep a distance of at least 20 cm between you (or any other person in the vicinity) and the Access Point antennas. 2007 Meru Networks, Inc. Regulatory Information 23 USA Federal Communications Commission (FCC) Radio Frequency Interference Requirements Interference Statement Note:

Meru Networks 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. Connect the device into an outlet on a circuit different from that of other electronics. Consult the dealer or an experienced radio technician for help. Note:

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

ment. This device must not be co-located or operating in conjunction with any other antenna or transmitter. 24 Meru Access Point and Radio Switch Installation Guide 2007 Meru Networks, Inc. Canada. Industry Canada (IC) Canada. Industry Canada (IC) This device complies with RSS210 of Industry Canada. 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. 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. Caution! Exposure to Radio Frequency Radiation. The installer of this radio equipment must ensure that the antenna is located or pointed such that it does not emit an RF field in excess of Health Canada limits for the general population; consult Safety Code 6, obtainable from Health Canadas website http://www.hc-sc.gc.ca/rpb.
