2140 Maintenance Procedures for Avaya Communication Manager 3.0, Media Gateways and Servers
16 FAIL Every power supply 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, then the system will be
referencing the local oscillator on the active TN780 Tone-Clock circuit
pack until software detects that one or both power supplies have been
restored (approximately 40 minutes). To speed up this restoration, use
test synchronization r 4.
3. Every test should pass. If any repetitions should fail, then follow the
procedures for those failures.
Note: The battery backup resides under the Stratum-3 clock’s carrier.
32 FAIL Every clock unit failed.
1. Look at the Stratum-3 cabinet for red LEDs on circuit cards marked
“ST3.” Replace the card(s).
2. To determine whether the alarm still exists, execute
test synchronization r 4 to clear the alarm.
3. If any test repetitions fail, then follow the procedures for those failures.
2101 FAIL The TN780 Tone-Clock circuit pack detects loss of signal. See note h 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
see SYNC (Port-Network Synchronization)
on page 2143 for recommended
strategy for those errors.
