Serial Bus Status Test (#1531)
4. Run list configuration power-supply C to determine if
some power supplies are still not showing and the Serial Bus fault
is still present.
5. If the fault is still present:
1. Check if the backplane pins in the removed circuit pack’s slot
appear to be bent.
2. If the backplane pins are not bent, reinsert the circuit pack(s),
and perform this Procedure 1 for the next set of circuit packs.
3. If the backplane pins are bent, remove power to the carrier by
unplugging the two AC cords on the back, and the one DC
input cord on the back, if there is one.
4. Straighten or replace the pins and reinsert the circuit pack.
5. Restore power and repeat Procedure 1, beginning with Step
2, for the same circuit pack(s).
6. If the fault is not present:
1. Reinsert the circuit pack(s) one at a time, and repeat the
following substeps until all of the circuit packs have been
reinserted.
2. Run list configuration power-supply C to
determine if the Serial Bus fault has returned.
3. If any of the power supplies don’t show, the reinserted circuit
pack is defective. Replace this circuit pack and repeat this
procedure for the next circuit pack.
4. If none of the power supplies fail to show when all of the
circuit packs have been reinserted, the problem has been
fixed and the procedure is completed.
