2304 ABORT SNC circuit pack responded that it is not able to run the test requested by
software.
1. Retry the command at 1-minute intervals up to 3 times.
2306 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
Pack)’’ on page 8-1384 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 test failed. Replace the SNC circuit pack.
PASS No problems exist with the TPN microcontroller.
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.
