SNI-BD (SNI Circuit Pack)
Issue 1 May 2002

120 FAIL The SNI circuit pack cannot communicate with the SNI in slot 20 over the
packet path.
1. Fix any on-board SNI-BD errors against this SNI and the SNI in slot 20.
Use the display errors command to find any SNI-BD errors and use the
display alarms command to determine whether the errors have on-board
alarms. Then, follow the associated repair procedures for the SNI-BD as
described in the Maintenance manual.
2. Using the display errors command, check the error log for other SNI
circuit packs with SNI-PEER error type 3841. If other SNI circuit packs
have SNI-PEER error type 3841 errors, replace the SNI in slot 20.
Replacing an SNI may be service interrupting. See ‘‘SNI-BD (SNI Circuit
Pack)’’ on page 8-1429 for the procedure for replacing an SNI.
NOTE:
If other SNI circuit packs do not have SNI-PEER error type 3841 errors,
the problem could be at either of the peer SNI boards. It is arbitrary as to
which SNI is replaced first.
3. Replace the SNI being tested.
4. Replace the SNI in slot 20.
