ABORT
The SNC circuit pack is not responding to test requests sent by software.
1. Run the test led switch-node for the switch node where this board resides
to verify whether the LEDs on the board light.
2. If the LEDs on the other boards in the carrier light, but the LEDs on this
board do not light, run test 760 via test board UUCSS l for the active SNC
in this carrier. Wait 5 minutes and then try step 1 one more time. If the
LEDs on this board still do not light, replace this board. Replacing an SNC
may be service interrupting. See
‘‘SNC-BD (Switch Node Clock Circuit
for the procedure for replacing an SNC.
3. If none of the LEDs light for the boards in the same carrier as this board, fix
any problems associated with the connectivity of this carrier to the server.
a. Use the list fiber link command to obtain a list of the fiber connections
to this carrier.
b. Check the LEDs on every SNI and EI, and fix any fiber problems.
c. Enter display errors, and follow the associated repair procedures for
any EXP-INTF error entries associated with the controlling
IPSI-connected EPN.
d. Follow the associated repair procedures for any SYNC, SNI-BD,
SNC-BD, FIBER-LK, or SNI-PEER error entries.
FAIL
The SNC circuit pack reported failures or retransmitted a “cleared failure”
message.
1. Check the error and alarm logs for SNC-BD, SNC-LINK, or SNC-REF
entries. Use the display errors and display alarms commands with
category PNC. Fix any problems found by referring to the SNC Board,
SNC Link, or SNC Reference Error Log Entries tables in this section and
follow the associated repair procedures.
2. If no SNC-BD, SNC-LINK, or SNC-REF errors exist in the error and alarm
logs, retry the command.
PASS
No problems are detected on the board.
