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 that the SNI resides in
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. Refer to the SNI-BD section 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 SPE.
Check list fiber-link to determine the fiber connections to this carrier.
Check the LEDs on all SNIs and EIs and fix any fiber problems. Enter
display errors and follow the associated repair procedures for any
EXP-INTF error entries associated with the PPN. Also, follow the
associated repair procedures for any SYNC, SNI-BD, SNC-BD, FIBER-LK,
or SNI-PEER e rror entr ies.
4. Follow the procedure described above, SNI Manual Loopback to
determine whether the circuit pack or the fiber connection is faulty.
127 FAIL The data is not correctly looped around.
1. Check the lightwave transceiver or metallic physical connections.
2. If connections OK, rep lace the lightwave transceive r or the metallic
interconnect.
3. If the test still fails, replace the SNI circuit pack.
PASS No problems associated with this test are detected on the SNI.
0NO
BOARD No board was detected by the test.
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
instead of reseating the c ircuit 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 p roblems.
3. Run the test again. If it fails, the ID chip on board may be bad. Replace
the board and retest.
