12. Busyout the fiber link (busyout fiber-link number ).
13. Test the fiber link (test fiber-link number long).
14. If any tests in the sequence fail, proceed with
below.
15. If all of the tests pass, clear the alarms by executing test board UUCSS
long clear for all alarmed EXP-INTF circuit packs. Wait 5 minutes for any
SNI-BD, SNI-PEER, FIBER-LK, or DS1C-BD alarms to clear.
Test the fiber link hardware
For each endpoint of the fiber link:
1. Busyout the circuit pack (busyout board UUCSS).
2. Test the circuit pack (test board UUCSS long) and record all test failures.
When looking at test results, consult the explanations for
page 2-31
3. Does Board Not Assigned display for an Expansion Interface in an
EPN?
4. If No , Did EXP-INTF Test #242 fail?
NOTE:
Test #759 may fail if SNI circuit packs are present.
NOTE:
Test attempted on the EI circuit pack in the SREPN do not run.
NOTE:
The clear firmware counters [ a-pnc | b-pnc ] command for the PNC
that was repaired may be quicker than clearing the alarms with the
test board UUCSS long clear command.

a. If Yes , use the test maintenance long command to release an
Expansion Interface that may be held reset by an EPN Maintenance
circuit pack.
NOTE:
Tests attempted on the EI circuit pack in the SREPN do not run.
a. If Yes, replace the EI circuit pack and the lightwave transceiver (if
present) and go back to Step 12 in the
procedure above.
NOTE:
EXP-INTF Test #242 runs an on-board looparound if no lightwave
transceiver is connected to the EI.
