2. Enter display errors and if no SNI-BD 1025 errors exist in the error
log, replace the active SNC.
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 sec tion
for these errors.
d. This error occurs whenever the ac tive SNC determines that there is a
problem communic ating 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 al so display the
active and standb y SNCs.)
2. If the system originally had duplicate SNCs and the standby SNC
was removed and never replac ed and the active SNC has not been
reset after the standby SNC was removed, this error will occ ur.
If you do not intend to replace the SNC:
a. Remove the standby SNC from circuit p ack administration
via change circuit-pack.
b. If the problem p ersists, replace the activ e SNC circuit pack.
Otherwise:
a. Insert an SNC circuit pac k.
3. Check the error log via display errors. If SNIs in the switch node
carrier also have problems c ommunicating with the ac tive SNC, i.e.
error code 257 is logg ed against SNI-BD, then replac e the active
SNC.
4. Replace the standby SNC c ircuit pack.
5. Retry the test board command. Check the error log via display
errors. If this error is still in the error log, replac e 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 standb y SNC determines that there is a
problem communic ating with the active SNC via the connec ting serial
channel.
1. If the active SNC (the one with its yellow LED on) has this error,
escalate the problem. (Status switch-node will al so display the
active and standb y SNCs.)
2. Check the error log via display errors. If more than one SNI in the
switch node carrier has p roblems communic ating with the active
SNC, i.e. error code 257 is logged against SNI-BD, then replace the
active SNC.
