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.

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.
