|
Warning Do not locate the antenna near overhead power lines or other electric light or power circuits, or where it can come into contact with such circuits. When installing the antenna, take extreme care not to come into contact with such circuits, because they may cause serious injury or death. For proper installation and grounding of the antenna, please refer to national and local codes (for example, U.S.:NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code, Section 54). Statement 1052

Caution Before connecting or disconnecting a power cord, you must remove AC power from the power cord using a suitable service disconnect.
Installation Guidelines
Because the access point is a radio device, it is susceptible to common causes of interference that can reduce throughput and range. Follow these basic guidelines to ensure the best possible performance:
•For information on planning and initially configuring your Cisco Mesh network, refer to the Deployment Guide: Cisco Mesh Networking Solution.
•Perform a site survey before beginning the installation.
•Install the access point in an area where structures, trees, or hills do not obstruct radio signals to and from the access point.
•The access points can be installed at any height, but best throughput is achieved when all the access points are mounted at approximately the same height. We recommend installing the access points no higher than 40 feet (12.2 meters) to allow support for wireless clients on the ground in the immediate vicinity of the access point; for example, directly below the access point.
Note To calculate path loss and to determine how far apart to install access points, consult an RF planning expert.
Site Surveys
Every network application is a unique installation. Before installing multiple access points, you should perform a site survey to determine the optimum use of networking components and to maximize range, coverage, and network performance.
Consider the following operating and environmental conditions when performing a site survey:
•Data rates—Sensitivity and range are inversely proportional to data bit rates. The maximum radio range is achieved at the lowest workable data rate. A decrease in receiver sensitivity occurs as the radio data increases.
•Antenna type and placement—Proper antenna configuration is a critical factor in maximizing radio range. As a general rule, range increases in proportion to antenna height. However, do not place the antenna higher than necessary, because the extra height also increases potential interference from other unlicensed radio systems and decreases the wireless coverage from the ground.
•Physical environment—Clear or open areas provide better radio range than closed or filled areas.
•Obstructions—Physical obstructions such as buildings, trees, or hills can hinder performance of wireless devices. Avoid locating the devices in a location where there is an obstruction between the sending and receiving antennas.

Step 1 Log into your controller web interface using a web browser.
You can also use the controller CLI show ap summary command from the controller console port.
Step 2 Click Wireless, and verify that your access point MAC address is listed under Ethernet MAC.
Step 3 Log out of the controller, and close your web browser.
Using the Reset Button
The access point has a reset button located on the bottom of the unit (see Figure 5). The reset button is recessed in a small hole that is sealed with a screw and a rubber gasket. The reset button can be used to perform these functions:
•Reset (power cycle) the access point—press the reset button for less than 10 seconds.The LEDs turn off for 5 seconds and then resume normal indication.
•Disable battery backup power—press the reset button for more than 10 seconds. The LEDs turn off for 5 seconds, turn back on for 5 seconds, then turn off and stay off.
