Notes:
a. This error occurs whenever the active SNC determi nes that there is a
problem communic ating with an SNI circuit pac k in the same carrier via
the connecting multip rocessor serial channel used for transmitting CSCN
messages. The slot location of the SNI with which the SNC cannot
communicate is given in Table 9-556.
1. Check the error log via display errors.
2. If any SNI-PEER errors exist in the hardware error log, follow the
assoc iate d rep air p roc edu res fo r SNI-PEER e rrors .
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 pac k.
4. If SNIs in the same carrier have SNI-BD error 257 logged indicating
they are having trouble communic ating with the SNC, replace the
SNC circuit pack.
5. Use list configuration carrier to determine whether an SNI is
physically present in the slot p ointed to by the SNC-LINK error. If
the Vintage field indicates that a circ uit pack is present, p roceed
to step 6. If the Vintage field repor ts no board, do one of the
following:
■If an SNI is not supposed to b e installed in this slot:
■Remove the SNI from circuit pack administr ation with
change circuit-pack.
■If the error remains, readminister the SNI circuit pac k and
then remove it from administration again.

2. Run the Short Test S e quence first. If all tests pass, run the Long Test Sequence. Refer to the appropriate
test description and follow the recommended proc edures.
