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 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.
FAIL The SNI circuit pack reported failures or retransmitted a “cleared failure”
message.
1. If this is the first time this test was run, run the test again. If there were any
previous failure messages that software did not acknowledge, this test will
FAIL even if the failure messages indicate a FAIL to PASS transition (i.e., a
problem has gone away). If this test is run twice and FAILs both times,
then at least one problem still exists.
2. Fix any SNI-BD, SNI-PEER, and FIBER-LK errors by following the
associated repair procedures. Use the display errors and display
alarms commands with category PNC for SNI-BD and FIBER-LK and
category PNC-PEER for SNI-PEER. Fix any problems found by referring
to the SNI Board or SNI Peer Error Log Entries tables in this section or
Fiber Link Error Log Entries tables in the ‘‘FIBER-LK (Fiber Link)’’ section.
3. If no SNI-BD, SNI-PEER, or FIBER-LK entries exist in the error and alarm
logs, retry the command.
PASS No problems are detected on the board.
