To align the antennas in the link using the RSSI output voltage, start with one antenna fixed and then perform the following procedure on the other antenna:

Note: The RSSI output can be configured through management interfaces to output a value for specific WDS ports. See page 6-54 for more information.

1.Remove the RSSI connector cover and connect a voltmeter using a cable with a male BNC connector (not included).
