120 FAIL The SNI circuit pack cannot communicate with the SNI in slot 20 over the circuit
path.
1. Fix any on-board SNI-BD errors against this SNI and the SNI in slot 20.
Use display errors to find any SNI-BD errors and check display alarms
to see whether the errors have on-board alarms. Then follow the
associated repair procedures for SNI-BD.
2. Check the error log via display errors for other SNI circuit packs with
SNI-PEER error type 3841. If other SNI circuit packs have SNI-PEER
error type 3841, then 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. Proceed as follows:
3. Replace this SNI.
4. Replace the SNI in slot 20.
122 FAIL The SNI circuit pack cannot communicate with its neighbor via the circuit path.
1. Fix any on-board errors (SNI-BD, EXP-INTF, and/or DS1C-BD) against the
components of this fiber link by using display errors and display alarms
and following the associated repair procedures. (Use the list fiber-link
command to find the fiber link associated with this SNI. The display
fiber-link command can then be used to find the endpoints of the fiber link
and the DS1C circuit pack locations if this fiber link has a DS1 Converter
complex administered.)
2. Enter display errors and follow the associated repair procedures for any
FIBER-LK entries for the fiber this SNI is administered on. Check list
fiber-link to determine the administered fiber.
3. If this fiber link has a DS1 converter complex administered, enter display
errors and display alarms and follow the associated repair procedures for
any off-board DS1C-BD or DS1-FAC entries for either of the DS1C boards
administered or for the DS1 facilities associated with either of the DS1C
boards administered.
4. Replace this SNI.
