ABORT
SNC firmware is not able to run the test.
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
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.
101
FAIL
The SNC circuit pack has on-board microcontroller failure.
128
FAIL
The SNC circuit pack has a problem with its clock; firmware has detected a
phase-locked loop failure, an inability to lock, or a failure of the clock drivers.
129
FAIL
The SNC circuit pack has a problem with the SNC on-board Stratum-3
oscillator.
130
FAIL
The SNC circuit pack has a problem with the TPN microcontroller.
1. Replace the SNC circuit pack.
PASS
No problems exist with the on-board functions verified by this test.
