4.3.7.1 Optical Switch Switching Criteria
Switch from primary to secondary:
When the primary optical power drops below the user defined threshold and the
secondary optical power is above the user defined threshold, the optical switch position moves over to the secondary optical
power immediately.
Recover from secondary to primary:
When the primary optical power is above the user defined threshold for one second,
the optical switch recovers back to primary position.
The optical switch position is persistently stored and the unit that recovers from power cycle will restore the optical switch
initial position according to its persistent value. The factory default is primary.
