6.
Using the
REMOVE
poke (or
RMV:MCTSI
input message), remove the
STBY (affected) side from service and proceed to Step
4.
Caution:
Updating the STBY MCTSI from an active MCTSI with
errors could potentially corrupt the STBY MCTSI memory.
4.
On the affected MCTSI, execute the MCTSI diagnostic demand Phase 7 (with the
Trouble Locating Procedure [TLP] option) several times. Type and enter:
DGN:MCTSI=a-b, PH=7,RPT=3,TLP;
Where:
a
=
The switching module number.
b
=
The MCTSI number (0 or 1).
5.
Perform Substep (
a
) or (
b
) as follows:
(a)
If the Phase 7 result is ATP, replace the suspected faulty memory pack (as
determined in Steps 1 & 2), repeat Step
4
, and verify that Phase 7 of the
MCTSI diagnostic runs consistently ATP.
(b)
If the Phase 7 result is not ATP, using the SUSPECTED FAULTY
EQUIPMENT printout, determine which pack is most likely causing the
failure, replace this pack, and verify that Phase 7 of the MCTSI diagnostic
now runs consistently ATP.
6.
Once the previous steps have been completed successfully, using the
RESTORE
poke command or the
RST:MCTSI
input message, restore the MCTSI.
7.
Verify that the MCTSI restored successfully (no hashsum failure after memory
update).
Note:
If after restoring the MCTSI the switching module errors continue, the
UN517 circuit pack could be the faulty pack.
If the MCTSI restores successfully, perform Substep (
a
). If the MCTSI does not
restore successfully, perform Substep (
b
).
(a)
Hold the interrupt and diagnostic printouts along with the suspected faulty
memory pack for a few days to verify that the memory errors have cleared.
Once it is determined that the memory errors have been cleared, attach the
interrupt and diagnostic printouts to the faulty memory pack and return the
pack to the appropriate repair center.
(b)
Hold the interrupt and diagnostic printouts along with the suspected faulty
memory pack and seek the next higher level of technical assistance to clear
the problem.
8.
STOP. YOU HAVE COMPLETED THIS PROCEDURE.
