The AP300 standard mounting bracket can be removed. The AP300 is also designed to be used
with brackets supplied by other vendors; if you use a bracket other than an AP150 bracket
(which is identical), you need to obtain three shoulder screws (see Appendix A). Meru APs can
be mounted on Cisco 1230 series brackets, but the Cisco 1240 and 1250 series brackets are new
and not compatible with the Meru bracket.
The AP300 has a security cable slot so you can lock the AP300 with a standard security cable,
such as those used to secure laptop computers. See Figure 3.

Additional Equipment
A power source is provided with the AP300. 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

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.

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.

Configure AP300 Software
You 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 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:

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).
