ABORT
The SNI circuit pack is not responding to test requests sent by software.
1. Run the test led switch-node for the switch node where the SNI 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 SNI
may be service interrupting. See
‘‘SNI-BD (SNI Circuit Pack)’’ on page
for the procedure for replacing an SNI.
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. Check list fiber-link to determine 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.
4. Follow the procedure described above, SNI Manual Loopback to determine
whether the circuit pack or the fiber connection is faulty.
102
FAIL
The SNI circuit pack cannot communicate with the SNI in slot 2 over the circuit
path.
1. Fix any on-board SNI-BD errors against this SNI and the SNI in slot 2. Use
display errors to find any SNI-BD errors and check display alarms to see
whether the errors have on-board alarms. Then follow the associated
repair procedures for SNI-BD.
2. Check the error log via display errors for other SNI circuit packs with
SNI-PEER error type 1. If other SNI circuit packs have SNI-PEER error
type 1, then replace the SNI in slot 2. Replacing an SNI may be service
interrupting. See
‘‘SNI-BD (SNI Circuit Pack)’’ on page 8-1429
for the
procedure for replacing an SNI.
3. If other SNI circuit packs do not have SNI-PEER error type 1 errors, the
problem could be at either of the peer SNI boards. It is arbitrary as to
which SNI is replaced first. Proceed as follows:
4. Replace this SNI.
5. Replace the SNI in slot 2.
