Alarm Parameters
The following table defines the alarm parameters for the optical switch.
Alarm Name Error Condition
Loss of Input Optical input at path A is less than the
Light at Path A switching threshold at path A
Loss of Input Optical input at path B is less than the
Light at Path B switching threshold at path B
Both Dark Loss of light at both inputs
(Loss of Input Light at Path A and Loss of
Input Light at Path B)
