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 the SNC 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.
2500 ABORT Internal system error
1. Retry the command at 1-minute intervals up to 3 times.
PASS The “reset” message was sent out successfully to the active SNC or to an SNI.
A PASS does not necessarily mean the SNC circuit pack was successfully
reset. The reset can be verified by checking that the red and green LEDs turn
on and then turn off. If an SNC circuit pack fails one of the firmware tests run
during its reset sequence, the red LED will stay on and the circuit pack should
be replaced.
