10 Meru AP300 Guide © 2007 Meru Networks, Inc.Install the Access Points Figure 6: Horizontal AP300Mount AP300 on a WallNote: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.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 screws3. 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.A2A2ALANRF1RF2200207
Check AP300 LED Activity © 2007 Meru Networks, Inc. Installing the AP300 11 Figure 7: Connect AP300 to LAN7. 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 ActivityAfter the AP300 is connected, the LEDs should light (see Figure 8).Figure 8: AP300 Status LEDsThe 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.

12 Meru AP300 Guide © 2007 Meru Networks, Inc.Configure AP300 Software Table 5: AP300 LED DescriptionsConfigure AP300 SoftwareYou can configure both the power source the AP300 will use and the channel width the AP300 will use. 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 CLIUse 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 #.

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 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.Note:The Short Preamble Setting affects 11b clients only. The Protection Mechanism setting has no effect at this time.
Troubleshooting © 2007 Meru Networks, Inc. Installing the AP300 17 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.TroubleshootingzIf 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.zWhen 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.zThe 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).

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.
24 Meru Access Point and Radio Switch Installation Guide © 2007 Meru Networks, Inc.USA — Federal Communications Commission (FCC) Radio Frequency Interference RequirementsInterference StatementThese 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. This device must not be co-located or operating in conjunction with any other antenna or transmitter.Note:Meru Networks Meru Access PointThese 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. Note:The Meru Networks Meru Access Point must be installed and used in strict accordance with the manufacturer’s 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.

L’utilisation de ce dispositif est autorisée seulement aux conditions suivantes: (1) il ne doit pas produire de brouillage et (2) l’utilisateur du dispositif doit étre prêt à accepter tout brouillage radioélectrique reçu, même 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 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.
