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 

 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 

 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.

Investigate tests in the order presented below. Clearing error codes associated with the one test 
may also clear errors generated from other tests in the sequence.
