3 FAIL The reset over the optical fiber failed.
1. Execute the test board PCSS command on the PN neighbor EI circuit
pack located on the opposite end of the fiber from this EI circuit pack. If
Test #238 does not pass, follow the maintenance procedure associated
with this test result. Then perform the reset again.
2. If the EI circuit pack is in the PN, temporarily remove the PN’s Maintenance
circuit pack.
3. Repeat the reset board PCSS command.
4. Reinsert PN’s Maintenance circuit pack if it was removed.
5. Follow the procedure described in the “Relationship Between Expansion
Interface and Tone-Clock Circuit Packs” section if the symptoms match
those described there.
6. Check the Error Log for the PN Tone-Clock errors that were resolved about
the same time when the PN went down. These PN Tone-Clock errors may
have been resolved because the PN went down. When there is no
Tone-Clock generating the system clock on an PN, then an EI circuit pack
can only be reset once. Every subsequent reset attempt fails. It is also
possible that the system itself may have already tried to reset the EI circuit
pack. See ‘‘TONE-BD (Tone-Clock Circuit)’’ on page 8-1659 for
recommended maintenance strategy for Tone-Clock problems.
7. If the reset still fails, execute the Manual Loop Back Procedure on the
opposite PN EI circuit pack. This procedure is described in the section
preceding the Hardware Error Log Entries and Test to Clear Values table
for this MO. If the EI circuit pack and the lightwave transceiver are healthy,
the problem must lie with the EI circuit pack and its lightwave transceiver
on the PN end of the fiber or with the fiber itself. Test the PN EI circuit pack
with the manual loop back procedure and investigate the test results.
