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 R elatively 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.

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 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. I f 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 anchors1/8-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

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).
