Demand test descriptions and error codes - Avaya Support

. This error occurs when the active SNC determines that there is a problem communicating
with an SNI circuit pack in the same carrier via the connecting multiprocessor serial chel
used for transmitting CSCN messages. The slot location of the SNI with which the SNC cot
communicate is given in SNC-LINK Error Log Entries.
1. Use display errors to check the error log.
2. If a SNI-PEER error exists in the error log, follow the repair procedures for SNI-PEER
(SNI Peer Link).
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 shows no board:
If an SNI should not be installed in this slot:
- Remove the SNI from circuit pack administration with change circuit-pack.
- If the error remains, re-administer 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:
8. Replace the SNC circuit pack.
9. If a standby SNC (the one with its yellow LED off) has this error, escalate the problem.
Use status switch-node to show the active and standby SNCs.
c. This error occurs when the active SNC determines that there is a problem communicating
with an SNI circuit pack in the same carrier via the TPN communication chel. The slot
location of the SNI with which the SNC cot communicate is given in Table 233: SNC-LINK
Error Log Entries.
1. Use display errors to check the error log. If more than one SNI in the same carrier
have SNI-BD errors with Error Type 769, replace the SNC.
2. Use display errors to check the error log. If the SNC has more than one
SNC-LINK error with Aux Data of 2, replace the SNC.
