Corrective Action
NOTICE
Service-disruption hazard
A cold reset, reseat, or replacement of a card is service impacting if the card is currently
carrying services. To determine if any services are currently carried over a card, perform
the procedure “Reseating a Card” (p. 3-19).
If
there are services currently carried over the card, it may be best to wait for a
maintenance window before resetting, replacing, or reseating the card.
At the end of each step wait to see if the fault clears. If not, continue with the next step.

1
Perform a warm reset on the card where the MOD condition is raised.
CLI config card card_type shelf slot reset warm
WEBUI Select the card, click the Reboot tab, select Warm Reboot >Submit.

Do the following for MVAC, SVAC or VA ports:
1. Verify that the fiber patch cable(s) between the source optical port and the encoder
port input are not kinked or bent at a tight radius, which could increase optical
insertion loss between components. If any are kinked or bent, gently correct, and then
wait 5 minutes before proceeding to the next step.
2. Verify that the fiber patch cable(s) between the source optical port and the encoder
port input are not dirty or damaged (this step is service affecting). Verifying and
cleaning the fiber connectors requires disconnecting the output of the source optical
port (for example, the L1 port of a 4DPA4 pack). After cleaning or patch cable
replacement, wait 5 minutes to see if the alarm clears.
3. Verify that the output power from the source optical port is as expected given the
interface type. Measuring with an optical power meter is service affecting, as it
requires disconnecting the output of the source optical port. If necessary, replace the
source optical transmitter and wait 5 minutes to see if the alarm clears.

Perform a cold reset of the card.
Note: Refer to Caution at the beginning of this procedure.
CLI config card card_type shelf slot reset cold
WEBUI Select the card, click the Reboot tab, select Cold Reboot >Submit.
