FAIL

PN’s Maintenance circuit pack did not respond to Sanity Handshake and 
the test timed out.

1. Verify that the carrier A power units are good. If the -5 Volt unit is 

defective in the A carrier, then communication with the PN’s 
Maintenance circuit pack will not be possible.

2. If the -5 Volt unit is good and this test continuously fails, background 

maintenance will automatically escalate to a PN’s Maintenance 
circuit pack Reset test (#306). Otherwise, manually reset a PN’s 
Maintenance circuit pack by issuing test maintenance long 

and evaluating any generated Error Codes from Test #306. If Test 
#306 passes, this test should also PASS. Use the following steps to 
determine whether the PN’s Maintenance circuit pack or its serial 
link, is defective:

Duplicated Port Network Connectivity (PNC):

1. Switch PNC by entering reset pnc interchange.
2. Run the short test sequence against the PN’s Maintenance circuit 

pack. If Test #106 still fails, replace the Maintenance circuit pack and 
retest. Otherwise, follow the error routines for any errors that are 
logged by this short test.

Unduplicated PNC:

1. Replace the PN’s Maintenance circuit pack, and invoke the short 

test sequence against it.

2. If error persists, replace the PN Expansion Interface 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.

PASS

The communications path to and from the PN’s Maintenance circuit pack 

is sane, and the Maintenance circuit pack can read and report the correct 

PN cabinet type. The Maintenance circuit pack may still have problems 

related to Tests #228, #229, #303, or #306.
