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/n Radios or 802.11b/g/n Radios and a list of associated access points
appears.
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 18 lists the controller power settings and the corresponding output power levels for these two
examples:
• 2.4 GHz ) operation in EMEA (–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
• For 802.11b/g/n (see Table 7-4 and Table 18), the manual controller Tx Power Level setting is 2.
• For 802.11a/n (see Table 7-5 and Table 18), the manual controller Tx Power Level setting is 2.
Step 8 Click Apply.

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.
