FAIL 3. Look for DS1-BD (DS1 Interface Circuit Pack) errors
using the display error command. Refer to the
DS1-BD Maintenance documentation for
recommended strategy to resolve any DS1-BD
errors found. If there are no DS1-BD errors, proceed
to Step 5.
4. After all DS1-BD errors have been resolved,
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.
5. Check the DS1 reference A connections to the
Stratum 3 clock.
6. 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.
2 FAIL One power supply failed. This error only 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 by looking for a
power supply with a red LED and replace it.
2. Determine if the alarm still exists by issuing the test
synchronization r 4 command to clear the alarm. If
any test repetitions fail, then follow the procedures
for those test failures. If the problem persists after
you have performed this procedure three times, then
follow normal escalation procedures.
