3. Enter display errors and if any SNI-BD 1025 errors exist in the
error log, follow the associated repair procedure in the SNI-BD
section for these errors.
d. This error occurs whenever the active SNC determines that there is a
problem communicating with the standby SNC via the connecting serial
channel.
If the switch node carrier is administered with duplicate SNCs:
1. If the standby SNC (the one with its yellow LED off) has this error,
escalate the problem. (Status switch-node will also display the
active and standby SNCs.)
2. If the system originally had duplicate SNCs and the standby SNC
was removed and never replaced and the active SNC has not been
reset after the standby SNC was removed, this error will occur.
If you do not intend to replace the SNC:
a. Remove the standby SNC from circuit pack administration via
change circuit-pack.
b. If the problem persists, replace the active SNC circuit pack.
Otherwise:
a. Insert an SNC circuit pack.
3. Check the error log via display errors. If SNIs in the switch node
carrier also have problems communicating with the active SNC (i.e.,
error code 257 is logged against SNI-BD), then replace the active
SNC.
4. Replace the standby SNC circuit pack.
5. Retry the test board command. Check the error log via display
errors. If this error is still in the error log, replace the active SNC.
If the switch node carrier is administered with only one SNC:
1. If step 2 above does not apply, replace the SNC.
e. This error occurs whenever the standby SNC determines that there is a
problem communicating with the active SNC via the connecting serial
channel.
1. If the active SNC (the one with its yellow LED on) has this error,
escalate the problem. (Status switch-node will also display the
active and standby SNCs.)
2. Check the error log via display errors. If more than one SNI in the
switch node carrier has problems communicating with the active
SNC (i.e., error code 257 is logged against SNI-BD), then replace
the active SNC.
3. If a single SNI has SNI-BD error 257, replace the SNI circuit pack.
