FIBER-LK (Fiber Link)
Issue 1 June 2005 1291
2306 ABRT A fiber link’s SNI circuit pack is not responding to test requests sent by
software.
1. Run the test led switch-node for the switch node where the SNI
board(s) reside to verify whether their LEDs light. If not, continue with
the following steps.
2. If LEDs light on other boards in the same carrier (but not on this
board), enter test board location long (#760) for the active
SNC in this carrier. Wait 5 minutes, and try step 1 again. If the board’s
LEDs still do not light, replace the board. (Replacing an SNI may be
service interrupting. Refer to the SNI-BD section for the procedure to
replace an SNI.)
3. If no LEDs light on any board in the same carrier, fix any connectivity
problems between this carrier and the media server. Use list
fiber-link to list the fiber connections to this carrier. Check the
LEDs on every SNI and EI, and fix any fiber problems. Enter display
errors, and resolve any SYNC, SNI-BD, SNC-BD, FIBER-LK, or
SNI-PEER error entries.
2500 ABRT Internal system error
1. Retry the command at 1-minute intervals up to 3 times.
141 FAIL The SNI circuit pack (Endpoint 1 of the fiber link) has a fiber out-of-frame
condition, but no loss-of-signal condition. Also, a 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.
