1
Pan the antenna horizontally back and forth while checking the LEDs. If using the pole-
mounting bracket with the unit, you must rotate the mounting bracket around the pole.
Other external antenna brackets may require a different horizontal adjustment.
2
Find the point where the signal is strongest (all LEDs on) and secure the horizontal
adjustment in that position.
3
Loosen the vertical adjustment on the mounting bracket and tilt the antenna slowly up and
down while checking the LEDs.
4
Find the point where the signal is strongest and secure the vertical adjustment in that
position.
Troubleshooting
Refer to the 3Com WL-575 Outdoor Building-to-Building Bridge and Access Point User's Guide or
the 3Com website (www.3Com.com) for troubleshooting information.
Note:
The RSSI value can be configured through management interfaces to display a value
for specific WDS bridge links.
Note:
Sometimes there may not be a central lobe peak because vertical alignment is too
far off; only two similar peaks for the side lobes are detected. In this case, fix the antenna
so that it is halfway between the two peaks.
