Ubiquiti Networks airFibe5X - Manual (Page 25)

4. Slave Aim the Slave at the Master to achieve the strongest
signal level on the Master.
Note: Refer to the Signal LEDs section for details on
the signal values.
Note: Maximum signal strength can best be
achieved by iteratively sweeping through both
azimuth and elevation.
5. Master Aim the Master at the Slave to achieve the
strongest signal level on the Slave.
6. Repeat steps 4 and 5 until you achieve an optimal link, with
all four Signal LEDs solidly lit. This ensures the best possible
data rate between the airFiber radios.
7. Lock the alignment on both airFiber antennas by
tightening all the nuts and bolts.
8. Observe the Signal LEDs of each airFiber radio to ensure
that the values remain constant while tightening the nuts
and bolts. If any LED value changes during the locking
process, loosen the nuts and bolts, finalize the alignment
of each airFiber antenna again, and retighten the nuts
and bolts.
