PN Maintenance Circuit Pack Serial Link
Test (#337)
This test is destructive.
This test checks the serial link from the standby EI circuit pack to the PN’s
Maintenance circuit pack. If there is no standby link, or the standby link is down at
the time of the test, this test will abort.
NOTE:
The status of the link is changed to “down” when the standby EI circuit pack
begins initialization tests (for example, after being reset). The link status is
then updated at the conclusion of these tests.

Result Description / Recommendation
1000 ABORT System resources required for this test are not available.
1. Retry the command at 1-minute intervals up to 5 times.
2029 ABORT
2500 Internal system error.
1. Retry the command at 1-minute intervals up to 5 times.
FAIL The serial link between the currently standby EI circuit pack and the PN’s
Maintenance circuit pack is defective. If the standby EXP-INTF is on the A
carrier, then error type 3329 is logged. If the standby EXP-INTF is on the B
carrier, then error type 3585 is logged.
1. If error type 3585 was logged, check to see if the ICCA/ICCB cables
between carriers A and B are present and properly connected (ICCA to
ICCA, and ICCB to ICCB). Install or reconnect the cables if necessary, and
rerun the test.
2. Replace the PN’s Maintenance circuit pack.
3. Rerun the test. If the test continues to fail, replace the standby PN
Expansion Interface circuit pack.
4. Rerun the test. If the test continues to fail and the standby link is on the
B carrier, then replace the ribbon cable that carries the serial link from
Expansion Interface circuit pack B to the PN’s Maintenance circuit pack.
PASS The serial link from the standby Expansion Links to the PN’s Maintenance
circuit pack is working.
