SNI Fiber Out of Frame Query (#989)
This test is nondestructive.
The SNI circuit pack reports whether a fiber out-of-frame condition exists, whether
a loss-of-signal condition exists, and whether the lightwave transceiver is present.
2306 ABORT An SNI circuit pack on the fiber link is not responding to test requests sent by
software.
1. Run the test led switch-node for the switch node(s) where the SNI(s)
reside to verify whether the LEDs on the board(s) light. Follow the steps
below for the SNI(s) from step 1 that had no LEDs 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. Refer to the SNI-BD section for the procedure
to replace 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 media
server. Use list fiber-link to determine the fiber connections to this carrier.
Check the LEDs on every SNI and EI, and fix any fiber problems. Enter
display errors and resolve any EXP-INTF error entries associated with
the PPN. Also, resolve any SYNC, SNI-BD, SNC-BD, FIBER-LK, or
SNI-PEER error entries.
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. Resolve any errors or alarms (display errors and display alarms) for
SNI-BD, SNI-PEER, and FIBER-LK entries.
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.
