3. If the SNC has SNC-LINK errors with aux data of 1 against other
SNIs and/or has SNC-BD error 513, replace the SNC circuit pack.
4. If SNIs in the same carrier have SNI-BD error 257 logged indicating
they are having trouble communicating with the SNC, replace the
SNC circuit pack.
5. Use list configuration carrier to determine whether an SNI is
physically present in the slot pointed to by the SNC-LINK error. If
the Vintage field indicates that a circuit pack is present, proceed
to step 6. If the Vintage field reports no board, do one of the
following:
■ If an SNI is not supposed to be installed in this slot:
■ Remove the SNI from circuit pack administration with change
circuit-pack
.
■ If the error remains, readminister the SNI circuit pack and
then remove it from administration again.
■ If the error still remains, replace the active SNC circuit pack.
■ If an SNI should be installed in this slot, but is missing, insert
an SNI circuit pack.
6. Replace the SNI that the SNC is complaining about.
7. Retry the command. If this error is still in the error log, continue with
the following steps.
8. Replace the SNC circuit pack.
9. If a 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.)
b. This error occurs whenever the active SNC determines that there is a
problem communicating with an SNI circuit pack in the same carrier via the
TPN communication channel. The slot location of the SNI with which the
SNC cannot communicate is given in Table 8-573 on page 8-1422.
1. Check the error log via display errors. If more than one SNI in the
same carrier have SNI-BD errors with error type 769, replace the
SNC.
2. Check the error log via display errors. If the SNC has more than
one SNC-LINK error with aux data of 2, replace the SNC.
