120 FAIL The SNC circuit pack cannot communicate with the SNI in slot 20.
1. If a standby SNC (one with its yellow LED off) was tested and resulted in
this error code, follow nor mal escalation procedures. (status switch-node
will also display the active and standby SNCs.)
2. Use list configuration carrier to determine whether an SNI is physically
present in slot 20. If the Vintage field indicates that a circuit pack is
present, proceed to step 3. If the Vintage field re ports no board, do one
of the following:
If an SNI is not supposed to be installed in slot 20
a. This failure will not affect service. The missing SNI can be removed from
administration with change circuit-pack.
b. If the error persists, reset the active SNC circuit pack with reset board
UUCSS. If the error still persists, replace the active SNC circuit pack.
If an SNI is supposed to be installed in slot 20, insert one.
3. Display errors for category pnc. If the SNC has SNC-BD error 513, or
SNC-LINK errors with aux data 1 pointing to other SNIs besides the one in
slot 20, replace the active SNC circuit pack.
4. If SNIs in the same carrier have SNI-BD error 257 logged, (indicating they
are having trouble communicating with the SNC), replace the active SNC
circuit pack.
5. If the SNC being tested has SNC-LINK error type 3841, replace the SNI in
slot 20. Replacing an SNI may interrupt service. Refer to the SNI-BD
section for the procedure for replacing an SNI.
6. If the SNC being tested still has SNC-LINK error type 3841, replace the
SNC circuit pack.
PASS The administered data and the circuit packs the SNC can communic ate with
match.
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 should
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.
