If resolving upstream alarms does not clear the alarm on the local NE, then the problem
may be with this NE. Find the source of the channel's service and ensure that the add
cross connect is administratively up and that there are no Wavelength Tracker or channel
alarms/conditions for the associated OT or SVAC. If there are, clear those
alarms/conditions.

3
Retrieve the configured topology upstream from this port to the service's ingress point
into the NE. Ensure that the physical fiber topology matches.

If there are numerous instances of this condition occurring on a particular card, check to
see if these alarms are also occurring on the next downstream card. If they are, then
continue with Step 5. If they are not occurring at the next downstream card, then there
may
be a problem with the indicated card. Reset the card, and wait for one minute. If the
alarms do not clear, continue with Step 5.

Verify that the loss in the fiber feeding the port is not higher than expected by comparing
the bulk powers ending and leaving the fiber. If the loss is higher than expected, clean the
fiber ends, and if this does not solve the problem, replace the fiber.

6
Perform a warm reset of the card.
CLI config card card_type shelf slot reset warm
WEBUI Select the card, click the Reboot tab, select Warm Reboot >Submit.

7
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.
