Fiber Misconnection—DPT Uplink Cards

Check for misconnected fiber cables (Side A to side A, TX to TX, span East to span East, and so forth) using the show srp command. Misconnection Alarm appears at the top of the show srp command output.

One alarm—Problem is with another node on the ring; for example, side A connected to side A.

Two alarms—Problem is your node.; for example, side A to side A and side B to side B.

Ensure that the duplex cables are not misconnected.

Fiber Misconnection—RPR/SRP Uplink Card

Check for misconnected fiber cables (span West to span West or TX to TX, and so forth) using the show rpr-ieee protection command. Misconnection Alarm appears at the bottom of the show rpr-ieee protection command output.

One alarm—Problem is with another node on the ring; for example, side West connected to side West.

Two alarms—Problem is your node; for example, span West to span West and span Eastto apan East

Ensure that the duplex cables are not misconnected.
