Table 8-583. TEST #989 SNI Fiber Out of Frame Query — Continued
Error Test
Code Result Description / Recommendation
146 FAIL The SNI circuit pack has a fiber out of frame condition, and a loss of signal
condition. Also, no lightwave transceiver is connected to the SNI circuit pack.
1. Check that the connected circuit pack is physically installed. The
2. If a lightwave transceiver is not supposed to be present, go to step 2. For
3. Perform the Fiber Fault Isolation Procedure described in Chapter 5.
4. Replace this SNI circuit pack.
5. Replace the connected 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

connected circuit pack is the other endpoint of the fiber-link if no DS1C
complex is administered (check via list fiber-link). Otherwise, if a DS1C
complex is administered, the connected circuit pack is the DS1C circuit
pack connected to the SNI circuit pack.
example, an SNI connected to a DS1C circuit pack or an SNI with a
metallic connection does not have a lightwave transceiver. Otherwise,
check the lightwave transceiver connections. If OK, replace the lightwave
transceiver. If a fiber out-of-frame condition exists and lightwave
transceivers are used, check that the lightwave transceivers are of the
same type, that is, both are 9823a or both are 9823b. If they are not the
same type, replace one of the lightwave transceivers:
9823a is used for distances up to 4900 feet.
9823b is used for distances up to 25,000 feet.
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.
