3. Replace the fiber link’s other endpoint if no DS1C complex is
administered on the fiber link. (Use list fiber-link to
determine whether a DS1C complex is administered). If so,
replace the circuit packs in this order:
i. Replace the DS1C circuit pack connected to this SNI.
ii. Replace the other DS1C circuit pack.
iii. Replace the fiber link’s other endpoint.
i. This error indicates a processor complex failure.
1. Replace the SNI circuit pack.
j. This error indicates that excessive slips have occurred.
Follow the steps for diagnosing synchronization problems when
slips have occurred in the SYNC section.
k. This error indicates that the SNI cannot communicate with its neighbor.
The SNI is at fault.
1. Replace the SNI circuit pack.
l. This error indicates that the SNI cannot communicate with one of its peers.
The SNI is at fault.
1. Replace the SNI circuit pack.

Descriptions and Error Codes
Always investigate tests in the order presented in the table below when inspecting
errors in the system. For example, by clearing error codes associated with the
Configuration audit (#759), you may also clear errors generated from other tests
in the testing sequence.
