SNI-BD (SNI Circuit Pack)

2306 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 carrier 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
8-1429 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 packet
path.
1. Fix any on-board SNI-BD errors against this SNI and the SNI in slot 2. Use
the display errors command to find any SNI-BD errors and use the display
alarms command to determine whether the errors have on-board alarms.
Then, follow the associated repair procedures for the SNI-BD as described
in the Maintenance manual.
2. Using the display errors command, check the error log for other SNI
circuit packs with SNI-PEER error type 1. If other SNI circuit packs have
SNI-PEER error type 1 errors, 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.
NOTE:
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.
3. Replace the SNI being tested.
4. Replace the SNI in slot 2.
