2 FAIL One power supply failed. This error occurs when the Stratum-3 clock has
two power supplies, and one of them has failed. However, the clock can
function with one power supply.
1. Locate the failed power supply (the one with a red LED), and replace it.
The power supplies reside under the Stratum-3 clock’s carrier.
2. To determine whether the alarm still exists, use test
synchronization r 4 to clear the alarm. If any test repetitions fail,
then follow the procedures for those failures.
4 FAIL One clock unit failed.
1. Look at the Stratum-3 cabinet for a red LED on a circuit card marked
“ST3.” Replace the card.
2. To determine whether the alarm still exists, use test
synchronization r 4 to clear the alarm. If any test repetitions fail,
then follow the procedures for those failures.
