If you want to use a PoE, you need to provide one of the following: z 802.3af compliant PoE device (for 2x2 mode) z 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 interconnected equipment's associated LAN connection. In addition, the AP300 should be mounted in a location that meets the following conditions: z 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 Install the Access Points z 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: z Install APs toward the center of the building. z Do not install APs near metal objects, such as heating ducts, metal doors, or electric service panels. z Relative to the ground, orient the antenna up or down, not sideways. The previous guidelines are general guidelines. Each site has its own unique environment. Place access points accordingly. Note: 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. 00207 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: z Antenna Standard multiband, omni-directional white antenna (included) z Standard Antenna Gain ~ 2.2 dBi for 2.4 GHz,and 3 dBi for 5 GHz z 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. Meru AP300 Guide © 2007 Meru Networks, Inc. Install the Access Points 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. antenna connector Figure 5: AP300 Antenna Connection 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. Caution! 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: z Horizontally on a surface, for example set the AP300 on a shelf z Vertically on a wall z 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 Install the Access Points 00207 Figure 6: Horizontal AP300 Mount AP300 on a Wall 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 don’t have to remove the old brackets. Note: 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 3. If you are using plastic anchors, install them in the holes. 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 CON 00209 5V DC LAN Ethernet Port Figure 7: Connect AP300 to LAN 7. Either connect an external power supply to the power connector and plug it into the wall, or connect an appropriate PoE power device to the Ethernet port (see Figure 7). Check AP300 LED Activity After the AP300 is connected, the LEDs should light (see Figure 8). 00208 power status LAN RF1 RF2 Figure 8: AP300 Status LEDs The functions of the five LEDs are described in Table 5. When the AP300 is first connected to the controller and any time the access point is rebooted thereafter, the AP initializes with and then is programmed by the controller. When the AP is first powered up, all LEDs are green. Thereafter, the Status LED (see Figure 8) color reflects the various operating states ( Table 5). © 2007 Meru Networks, Inc.

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.

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 z 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. z 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. z The ChannelWidth field value 40 Mhz-extension-channel-above is only applicable if the extension channel above is available in the country code. For example, A_EXT_CHANNELS=36:40 case, 40 Mhz-extension-channel-above configuration is valid for channel number 36. Currently we support extension channels in only the US country code. In addition, the default channel numbers for RF mode BG or A mode are changed in the US country code (DEFAULT_B_CHANNEL=6, DEFAULT_A_CHANNEL=36). © 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 interference, 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 installation. This equipment generates, uses, and can radiate radio frequency energy. If the equipment is not installed and used in accordance with the instructions, the equipment may cause harmful interference to radio communications. There is no guarantee, 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 encouraged 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.

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 l’objet d’une licence, il doit etre utilze a l’interieur et devrait etre place lin des fenetres afin de Fournier un ecram de blindage maximal. Si le matriel (ou son antenne d’emission) est installe a l’exterieur, il doit faire l’objet d’une 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 Canada’s website http://www.hc-sc.gc.ca/rpb.
