5. If none of the TDM Bus tests fail:
■
Re-insert the circuit pack.
■
Run the test tdm system technician command.
■
If any of the TDM Bus tests fail, the re-inserted circuit pack is faulty.
Replace the circuit pack and do this procedure again for the new
circuit pack.
■
If none of the TDM Bus tests fail, then the problem has been fixed.
Procedure 3
This procedure removes and re-inserts control carrier circuit packs one at a time.
The Network Control circuit pack and the Processor Interface circuit pack are the
only processor complex circuit packs that communicate on the TDM Bus, and thus
are the only processor complex circuit packs likely to cause a TDM Bus problem
in a stable system. This procedure should be performed for the Processor
Interface circuit pack before it is attempted for any other processor complex circuit
packs.
In a System Without High or Critical Reliability
To perform this procedure for the Network Control circuit pack, this circuit pack
must be replaced. The system cannot operate without the Network Control circuit
pack.
1. Power down the control carrier.
2. Remove the suspected circuit pack.
3. Check if the backplane pins in the removed circuit pack’s slot appear to be
bent.
4. If the backplane pins are bent:
■
Straighten or replace the pins.
■
Insert the same circuit pack.
■
Repeat from Step 2 with the same circuit pack.
5. If the backplane pins are not bent, insert or replace the circuit pack.
6. Turn the power back on to reboot the system.
7. Run the test tdm P command.
8. If any of the TDM Bus tests fail:
■
If the circuit pack in Step 5 was inserted, do this step again replacing
the circuit pack.
■
If the circuit pack in Step 5 was replaced, do this step again with the
next circuit pack.
9. If none of the TDM Bus tests fail, the problem has been fixed.
10. If this step fails to identify the cause of the problem, go to Procedure 4.
