using the rept-stat-trbl command. Replace the card if necessary. If the bad
clock error cannot be resolved, contact the

Note:
There should be no cards using bad clocks. If any card indicates a bad
clock, troubleshoot the card using the rept-stat-trbl command. Replace
the card if necessary. If the bad clock error cannot be resolved, contact

replacement.
From the output in 5, determine the IDLE clock cable.

Caution:
Always replace the IDLE clock cable first, whether it is the primary or
secondary cable position. After the replacement of the first (IDLE) cable
position, ensure the system reports the clock status properly with an
ACTIVE and IDLE clock output. If the output reports the correct status
the ACTIVE cable can be disconnected for replacement. Disconnecting
the ACTIVE cable will transition the previously IDLE clock to the ACTIVE
clock forcing the system to use the new clock cable that was installed.
Perform the following to prepare the open end of the new IDLE high‑speed source

and composite clock cable (P/N 830‑0873‑xx or P/N 830‑1189‑xx) for connection
to the customer's high‑speed and composite clock sources.
Remove the outer insulation to expose the wires.

Caution:
A system with DS0A links cannot run without a composite clock source.
Take extreme caution when replacing the composite clock source cables.
Remove one cable at a time and confirm between removal that the other
composite clock source is active.
