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. Determine if the alarm still exists by issuing the test
synchronization r 4 to clear the alarm. If any test
repetitions fail, follow the procedures for those
failures. If the problem persists after you have
performed this procedure three times, follow normal
escalation procedures.
8 FAIL Reference B failed or CI card B failed. This condition
usually indicates a failure of the DS1 reference;
however, there may also be a failure of the CI card to
which the reference is connected. System Technician
dispatched to investigate this problem should take a
spare CI card in case the CI card caused the failure.
If you are NOT ON-SITE, use the following procedure:
1. If there are no DS1-BD errors OR after resolving all
DS1-BD errors, issue the test synchronization r 4
command to determine if the alarm is still present. If
all repetitions of the tests pass, the alarm no longer
exists. Otherwise, system technician should be
dispatched with a spare CI card to use the following
instructions on-site.
If you are ON-SITE, use the following procedure:
1. Look for a red LED on a CI card B (the right CI card).
If there is a red LED, replace the CI card, if a spare
is available. If no spare CI is available on-site,
proceed to Step 3. If after replacing the CI card, the
red LED on the new CI card lights also, proceed to
Step 3.
2. Otherwise, issue the test synchronization r 4
command to clear the alarm. If any test repetitions
fail, follow the procedure for those failures.
