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.
