Fault Isolation for Fiber Links

■
If there are many SNI-PEER errors with the same error type, replace
the indicted SNI circuit pack using the following table.
■
After replacing an SNI circuit pack, clear alarms by executing test
board UUCSSlong clear for every alarmed EXP-INTF circuit pack.
Wait 5 minutes for any SNI-BD or SNI-PEER alarms to clear. To
speed this process use clear firmware counters [a-pnc | b-pnc]
for the PNC that was repaired.
■
Exit this procedure.
3. Enter list fiber-link to get the physical location of the fiber link’s endpoints.
If a DS1 CONV is administered to the fiber link (DS1 CONV is “y”), use the
display fiber-link command to get the physical location of the DS1 CONV
circuit packs on the fiber link.
4. Execute busyout fiber-link FP, followed by test fiber-link FP long.
If any tests in the sequence fail, proceed with step 5 .
If every test passes, clear alarms by executing test board UUCSS long
clear for every alarmed EXP-INTF circuit pack. Wait 5 minutes for any
SNI-BD, SNI-PEER, FIBER-LK, or DS1C-BD alarms to clear. You can
speed this process with clear firmware counters [a-pnc | b-pnc] for the
PNC that was repaired. You are finished with this procedure.
5. For each of the fiber link’s endpoints, follow this flowchart:
