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.

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.
