THIRD FCC DRAFT (CISCO CONFIDENTIAL)
Note For the signal level (dBm), a smaller number represents a stronger signal because the signal
level is given as a negative value.
When using LEDs to maximize the signal, adjust the antenna
until as many LEDs as possible are turned
on and the rest are blinking as fast as possible.
Aligning the Antenna Using the RSSI Voltage
The RSSI port produces a DC voltage that is proportional to the received signal level. The RSSI voltage
is available whenever a signal is present, regardless of the bridge mode (installation or normal),
association status, or pre configuration role setting. In Install mode, the RSSI voltage provides an
