Error<br />

Code<br />

Test<br />

Result<br />

FAIL<br />

(cont’d)<br />

Description and recommendation<br />

4. Run list configuration power-supply C to determine if<br />

some power supplies are still not showing and the Serial Bus fault<br />

is still present.<br />

5. If the fault is still present:<br />

1. Check if the backplane pins in the removed circuit pack’s slot<br />

appear to be bent.<br />

2. If the backplane pins are not bent, reinsert the circuit pack(s),<br />

and perform this Procedure 1 for the next set of circuit packs.<br />

3. If the backplane pins are bent, remove power to the carrier by<br />

unplugging the two AC cords on the back, and the one DC input<br />

cord on the back, if there is one.<br />

4. Straighten or replace the pins and reinsert the circuit pack.<br />

5. Restore power and repeat Procedure 1, beginning with Step 2,<br />

for the same circuit pack(s).<br />

6. If the fault is not present:<br />

1. Reinsert the circuit pack(s) one at a time, and repeat the<br />

following substeps until all of the circuit packs have been<br />

reinserted.<br />

2. Run list configuration power-supply C to determine if<br />

the Serial Bus fault has returned.<br />

3. If any of the power supplies don’t show, the reinserted circuit<br />

pack is defective. Replace this circuit pack and repeat this<br />

procedure for the next circuit pack.<br />

4. If none of the power supplies fail to show when all of the circuit<br />

packs have been reinserted, the problem has been fixed and the<br />

procedure is completed.<br />
