The ALARM C command cleas the alarm after you determine and correct the problem, or you can use
it to test a solution to a problem with the ONS 15216 EDFA1. Clearing active alarms resets
alarm-monitoring circuitry within the ONS 15216 EDFA1 and is useful in verifying whether alarm
conditions are present.
Alarm Enable/Disable Commands
Use the ALMDSBL command to disable a specific alarm. Use the ALMENBL command to enable the
specific alarm. Both commands are useful in determining the source of a problem, masking specific
alarms, or testing the ONS 15216 EDFA1.
See the “ALMENBL” section on page 5-13 for additional information about this command.

LOS Alarm Threshold Commands
Use the SET_LOS command to set, enable, disable, or display loss-of-input signal threshold. The
factory default is set to -30 dBm. Use this command to review the loss-of-signal threshold and (if
necessary) reset this value.
Note Changing the LOS alarm threshold requires a password.
