Server Alarms - Avaya Support

SNI-BD (SNI Circuit Pack)
Procedure 1
Suspect TPN link or clock generation out-of-lock problem:
1. Enter display alarms and display errors and follow the procedures for any
on-board SNI-BD error and alarm entries.
2. If more than one SNI circuit pack in the same switch node carrier has SNI-BD error
769 with an off board alarm, replace the active SNC in the same carrier.
3. Replace this SNI.
4. Replace the active SNC in the same carrier.
Procedure 2
Suspect clock generation out-of-lock problem:
5. If only one SNC exists in this switch node carrier, replace the SNC.
6. If two SNCs exist in this switch node carrier, set the standby SNC to active by running
set switch-node-clock location with the standby SNC’s location.
● If the problem goes away, replace the SNC that was previously active. Then use set
switch-node-clock location to set the SNC that was just replaced to active. If
the problem returns, assume that the SNC that was just replaced is not at fault and go
to Step 7.
● If the problem persists, switch back to the previously active SNC using set
switch-node-clock and go to Step 7.
7. Replace the left-most SNI from the pair of adjacent SNIs.
8. Replace the right-most SNI from the pair of adjacent SNIs.
9. If none of the above steps cleared this error, this could be a switch node carrier
backplane problem.
i. Error Type 1025: a failure communicating synchronization control data over the fiber link.
If the error is logged as an ON-BOARD error:
1. Replace the SNI circuit pack.
If the error is logged as an OFF-BOARD error:
1. Enter display errors and follow the repair procedures for FIBER-LK errors.
2. Replace the SNI with this error.
3. Replace the fiber link’s other endpoint if no DS1C complex is administered on the fiber
link. Use list fiber-link to determine if a DS1C complex is administered. If so,
replace the circuit packs in this order:
a. Replace the DS1C circuit pack connected to this SNI.
b. Replace the other DS1C circuit pack.
c. Replace the fiber link’s other endpoint.
