Changing the Lightweight Access Point Output Power
Follow these steps to change the access point’s output power to meet local regulations using a controller:
Step 1 Open your Internet browser. You must use Microsoft Internet Explorer 6.0.2800 or a later release.
Step 2 Enter https://IP address (where IP address is the controller’s IP address) in the browser address line
and press Enter. A user login screen appears.
Step 3 Enter the username and password and press Enter. The controller’s summary page appears.
Note The username and password are case-sensitive.
Step 4 Click Wireless > 802.11a Radios or 802.11b/g Radios and a list of associated access points displays.
Step 5 Choose the desired access point and click Configure. The radio settings page appears.
Step 6 Scroll down to the Tx Power Level Assignment field, and click Custom.
Custom indicates that the radio output power is manually controlled by the Tx Power Configuration
setting field.
Step 7 In the Tx Power Level field, select the appropriate power level setting (1 to 8).
Based on the operating channel, the regulatory domain, and the controller power level setting (1 to 8),
the actual transmit power at the access point can be reduced to comply with special regulatory or country
restrictions.
Table 6-7 lists the controller power settings and the corresponding output power levels for these two
examples:
• 2.4 GHz (802.11b/g) operation in –E regulatory domain:
–
Channel 2 using 11-Mbps data rates with 6-dBi external antenna
• 5 GHz (802.11a) operation:
–
Channel 52 with 6-dBi external antenna

1. The Tx Power Level setting of 1 represents the maximum conducted power setting for the
access point. Each subsequent controller power level (such as 2, 3, 4, etc.) represents
approximately a 3-dBm reduction in transmit power from the previous power level.
