FIBER-LK (Fiber Link)
Issue 1 June 2005 1293
144 FAIL The SNI circuit pack (Endpoint 1 of the fiber link) has a loss-of-signal
condition, but no fiber out-of-frame condition. Also, no lightwave
transceiver is connected to the SNI circuit pack.
1. Check that the connected circuit pack is physically installed. The
connected circuit pack is the other endpoint of the fiber link if no DS1
converter complex is administered (check via list fiber-link).
Otherwise, if a DS1 converter complex is administered, the connected
circuit pack is the DS1 converter circuit pack connected to the SNI
circuit pack.
2. Perform the Fiber link fault isolation
in Chapter 4: General
troubleshooting in Maintenance Procedures (03-300192) in Chapter 5.
3. Replace this SNI circuit pack.
4. Replace the connected circuit pack.
