10-1568 Issue 4 May 2002
16 FAIL All power supplies failed.
1. Replace the failed power supplies.
2. If battery backup for the Stratum 3 clock is not supplied or
if the battery backup holdover time has been exceeded,
the system references the local oscillator on the Active
TN780 Tone-Clock circuit pack until software detects one
or both power supplies has(have) been restored
(approximately 40 minutes). To speed up this restoration,
issue the test synchronization r 4 command. All tests
should pass. If any repetitions should fail, follow the
procedures for those failures. If the problem persists after
you have performed this procedure three times, follow
normal escalation procedures.
32 FAIL All clock unit(s) failed.
1. Look at the Stratum 3 cabinet for red LEDs on circuit
cards marked "ST3." Replace the card(s).
2. Determine if the alarm still exists by issuing the test
synchronization r 4 command to clear the alarm. If any
test repetitions fail, follow the procedure for those failures.
If the problem persists after you have performed this
procedure three times, follow normal escalation
procedures.
2101 FAIL The TN780 Tone-Clock circuit pack detects loss of signal.
Refer to Note (b) of the STRAT-3 Hardware Error Log Entries
table in the STRAT-3 (Stratum 3 Clock) Maintenance
documentation for replacement procedures.
PASS The Stratum 3 clock has reported that it has no alarm
conditions. If synchronization problems have been reported,
look for SYNC errors and refer to SYNC (Synchronization)
Maintenance documentation for recommended strategy for
those errors.
