EXP-INTF (Expansion Interface Circuit Pack)
Issue 1 June 2005 1221
3 FAIL The reset over the optical fiber failed.
1. Execute test board location on the PN neighbor EI circuit pack
located on the opposite end of the fiber from this EI circuit pack. If Test
#238 fails, 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 reset board location.
4. Reinsert PN’s Maintenance circuit pack if it was removed.
5. If the symptoms match those described in the EI and Tone-Clock
Interactions on page 1186 section, follow those guidelines.
6. Check the Error Log for the PN Tone-Clock errors that were resolved
when the PN went down. These errors may have been resolved
BECAUSE the PN went down. When there is no Tone-Clock
generating the system clock on a 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. Refer to TONE-BD (Tone-Clock Circuit)
on page 2327 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 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 is the EI circuit pack and its lightwave transceiver on the
PN end of the fiber or the fiber itself. Test the PN EI circuit pack with
the manual loop back procedure and investigate the test results.
PASS The EI was successfully reset. Remove the EI circuit pack from the
busyout state by using release board location.
1. Execute test board location short. Refer to errors for each
test.
