Table 8-577. TEST #756 SNI Off-Board Destructive Facility Test — Continued
Error Test
Code Result Description / Recommendation
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
2. If the LEDs on the other boards in the carrier light, but the LEDs on this
3. If none of the LEDs light for the boards in the same carrier as this board, fix
4. Follow the procedure described above, SNI Manual Loopback to determine
127 FAIL The data is not correctly looped around.
1. Check the lightwave transceiver or metallic physical connections.
2. If connections OK, replace the lightwave transceiver or the metallic
3. If the test still fails, replace the SNI circuit pack.
PASS No problems associated with this test are detected on the SNI.
0 NO No board was detected by the test.
BOARD
1. Check that board is properly translated and inserted.
2. Run the test again. If it fails, reset the board. An SNI should be reset
3. Run the test again. If it fails, the ID chip on board may be bad. Replace

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
8-1429 for the procedure for replacing an SNI.
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.

instead of reseating the circuit pack. The reset board command should
almost never be used on an SNI. It may be necessary to use the reset
board command if the SNI circuit pack gets into a mode where it cannot
communicate with software. If an SNI with active errors and alarms is
reset, the errors and alarms may take a while to come back, therefore the
reset board command can mask real problems.
