Demand test descriptions and error codes - Avaya Support

Procedure 1
SNI-PEER (SNI Peer Link)
Perform the following steps until the problem is resolved:
1. Perform the Fiber link fault isolation procedure in Maintenance Procedures for Avaya
Aura Communication Manager, Media Gateways and Servers (03-300432).
2. Replace the SNI pointed to by the SNI-PEER Error Type. See the SNI Slot column in
Table 237: SNI-PEER Error Log Entries.
3. Replace the SNI reporting the SNI-PEER error.
4. Replace the active SNC.
Procedure 2
Slot Numbers of
Adjacent SNIs
Point to this SNI Pair
17, 18 3073, 3329
19, 20 3585, 3841
If either of the two patterns described before are present, then the clock signal between active
SNC and 2 Adjacent SNIs is suspect. Proceed through the following steps until the problem is
resolved:
1. If only one SNC exists in this switch node carrier, replace the SNC. If two SNCs exist in
this switch node carrier, perform the following steps:
a. Set the standby SNC to active by executing set switch-node-clock location
with the standby SNC’s location.
b. If the problem persists, switch back to the previously active SNC using set
switch-node-clock and go to Step 2 below.
c. If the problem went away, replace the SNC that was previously active. Then set the
newly replaced SNC to active. If the problem returns, assume that the SNC that was
just replaced was not at fault and go to Step 2 below.
2. Replace the left-most SNI from the pair of adjacent SNIs.
3. Replace the right-most SNI from the pair of adjacent SNIs.
4. This could indicate a problem with the switch-node-carrier backplane.
