Save:
Press “Right” or “Left” button to select between “Yes” or “No”. Press “Select” to commit the value into NVRAM when
“Yes” is selected. The value in bracket refl ects the current NVRAM contents. If user presses “Select” when display is “No”,
no NVRAM change takes place.
NOTE: Failing to do so may result in the loss of the setting after a reboot/power cycle.
Threshold (dBm):
Press “Right” or “Left” button to increase or decrease the level of threshold in dBm for switching between
primary and secondary optical inputs. The factory default threshold is 0 dBm with the range -13 to 14 dBm.
Save:
Press “Right” or “Left” button to select between “Yes” or “No”. Press “Select” to commit the value into NVRAM when

3.3.2.5.1 Optical Switch Switching Criteria
Switch from primary to secondary:
When the primary optical power drops below the user defi ned threshold and the
secondary optical power is above the user defi ned 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 defi ned threshold for at least one
second, the optical switch recovers back to primary position.
