Failure Audit (#777)
This test is non-destructive.
This test queries the SNC for any existing failures and any unac knowledged cleared failure messages. Each failure g enerates an error and alarm entry against SNC-BD, SNC-LINK, or SNC-REF. An unacknowledged cleared failure message is a message the SNC circuit p ack sent to software indicating a previous failure is now gone and the SNC circuit pack did not receive a message from software indicating that the failure mess age was received by softwa re.If no failures are detected b y the SNC circuit pack, this test will p ass.
FAIL If this test fails, not all of the administered circuit packs in this switch node
carrier responded with an up-link board insertion message. Check to see that
administered SNI and SNC boards match the physically installed SNI and SNC
boards by entering list config carrier UUC. The command output will show
"NO BOARD" for every board that is administered , but not inserted.
■If all administered b oards are inserted, run this test ag ain.
■If administration does not match the physical configuration, and is correct,
insert the missing circuit packs in this switch node carrier.
■If

none

of the administered boards in this switch node carrier were inserted,
fix any other SN-CONF errors by following the associated repair
procedures for SN-CONF. Use display errors with category pnc to view
SN-CONF errors. Next check if any INLs, LNLs, or RNLs are down, refer to
the SYS-LINK section for fixing link problems.
PASS If this test passes, all of the administered circuit packs in this switch node
carrier were inserted.
0NO
BOARD No board was detected by the test.
1. Check that SNC board is properly translated and inserted.
2. Run the test again. If it fails, reset the board. An SNC should be reset
instead of reseating the circuit pack. The reset board command shoul d
almost never be used on an SNC. It may be necessary to use the reset
board command if the SNC circuit pack gets into a mode where it cannot
communicate with software. If an SNC with active errors and alarms is
reset, the errors and alarms may take a while to come back, therefore the
reset board command can mask real problems.
3. Run the test again. If it fails, the ID chip on board may be bad. Replace the
board and retest.
