none FAIL This Tone-Clock circuit pack had an apparent loss of
clock. One or more of error types 2049, 2305, 3834, and
3872 will appear in the error log. Correct the problem
according to the appropriate error log entries. Once this
test fails, the only way to make it pass, and to retire the
associated alarm, is to repair the problem and to
execute the set tone-clock PC override command
against the indicated Tone-Clock circuit pack.
NOTE:
If power is removed from a carrier in a duplicated
system, and that SPE has the active TONE-CLK, a
MAJOR alarm is raised for the TONE-BD. The
TONE-BD will be out of service and when running
Test 46 (Clock Health Test) it will fail, indicating a
loss of any of these three clocks, SYSCLK, SYSFM,
and SYSDCLK.
To restore the TONE-BD to service you must
execute the set tone spe health-override
command.
1 FAIL This Tone-Clock circuit pack is suspect of having a
clock at the edge of its specified frequency. A
Tone-Clock circuit pack with this problem can cause
Expansion Interface circuit packs to go out-of-frame or
report no neighbor conditions, thus causing EPNs to go
down
1. Replace the Tone-Clock circuit pack identified in the
error log. Refer to the ‘‘
How to Replace a Tone-Clock
Circuit Pack’’ section.
2. If the error persists, follow normal escalation
procedures.
PASS This Tone-Clock circuit pack has not reported a loss of
clock.
