MAINT (PN’s Maintenance Circuit Pack)

3. Replace the PN’s Maintenance circuit pack, and run the test again. If
the test passes, the problem is with the Maintenance circuit pack.
Interchange the PNC by entering reset pnc interchange, and
run the test again. The test should pass with both EI circuit packs
being active.
4. If the B carrier EI circuit pack is active, the ribbon cable connecting
the Expansion Interface circuit pack and the PN’s Maintenance
circuit pack may be defective. Check the ribbon cable to make sure it
is connected properly and is not damaged.
For unduplicated Port Network Connectivity:
1. Replace the PN’s Maintenance circuit pack, and run the test again. If
it passes, the problem is with the Maintenance circuit pack.
2. If the test fails, replace the EI circuit pack. If the tests passes, the
problem is with the EI circuit pack.
3. If the test still fails, the problem is with the serial link wired into the
backplane of carrier A.
2005 FAIL PN Maintenance Circuit Pack reset passed, but the PN’s Maintenance
circuit pack did not respond to subsequent handshake message. Retry
this command three more times. If it continues to fail, the Maintenance
circuit pack, the active EI circuit pack, or the serial link is defective. To
determine which is defective:
For Duplicated Port Network Connectivity:
1. Interchange PNCs by entering reset pnc interchange.
2. Run the short test sequence against the PN’s Maintenance circuit
pack. If Test #306 still fails, replace the Maintenance circuit pack and
retest. Otherwise, follow the error routines for any errors that are
logged by this short test sequence.
For Unduplicated Port Network Connectivity:
1. Replace the PN’s Maintenance circuit pack, and invoke the short
test sequence against it.
2. If the error persists, replace the EI circuit pack, at a time when the
PN can go down with minimal inconvenience.
3. If the error still persists, the problem is with the actual serial link in A
carrier backplane and not with the PN’s Maintenance circuit pack.
