LED Indicators
The LEDs are used for RSSI signal strength measurements to aim directional antennas
and to indicate the state of the WLA. The access point includes eight status LED
indicators, as shown below. The LEDs are viewed right to left as you look at the back of
the WLA.
The table below describes the system status LEDs.
The 11a and 11b/g LEDs operate in two display modes, which are configurable through
the management interface. The RSSI mode is for aligning antennas in a bridge link. The
WLA mode is for indicating data traffic rates.
The table below describes the wireless status LEDs in WLA mode.
