SNI Off-Board Destructive Facility Test (#756)
This test is destructive.
The SNI runs a destructive loop around of the on- and off-board loop arounds.
This test returns the result of the off-board loop around, while Test 757 returns the
result of the on-board loop around. For SNI-to-SNI fiber links, this test is run on
both SNI circuit pack endpoints of the fiber link.

Result Description / Recommendation
1015 ABORT The system will not allow this test to be run because the fiber link has not been
busied out. Busyout the fiber link with busyout fiber-link F P. Repeat the test
fiber-link F P long command.
2100 ABORT Could not allocate the necessary system resources to run this test.
2300 ABORT The downlink message necessary to run this test could not be sent.
2301 ABORT The software timer could not be set before sending the downlink message
necessary to run this test.
2304 ABORT SNI circuit pack responded that it is not able to run the test requested by
software.
1. Retry the command at 1-minute intervals up to 3 times.
2306 ABORT A fiber link’s 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 board(s)
reside to verify whether their LEDs light. If not, continue with the following
steps.
2. If LEDs light on other boards in the same carrier (but not on this board),
issue test board UUCSS l (#760) for the active SNC in this carrier. Wait 5
minutes, and try step 1 again. If the board’s LEDs still do not light, replace
the board. (Replacing an SNI may be service interrupting. Refer to the
SNI-BD section for the procedure to replace an SNI.)
3. If no LEDs light on any board in the same carrier, fix any connectivity
problems between this carrier and 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 SYNC, SNI-BD, SNC-BD, FIBER-LK, or SNI-PEER error entries.
