4. Replace the active SNC in the same carrier.
Procedure 2 (suspect clock generation out of lock problem):
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 running the
set
switch-node-clock UUCSS
command with the standby
SNC’s location.
b. If the problem goes away, replace the SNC that was
previously active. Then set the SNC that was just replaced to
active via the
set switch-node-clock UUCSS
command. If
the problem returns, assume that the SNC that was just
replaced was not at fault and go to step 2 below.
c. If the problem persists, switch back to the previously active
SNC via the
set switch-node-clock
command and go to
step 2 below.
2. Replace the leftmost SNI from the pair of adjacent SNIs.
3. Replace the rightmost SNI from the pair of adjacent SNIs.
4. If none of the above steps cleared this error, this could be a switch
node carrier backplane problem.
h. This error indicates a failure communicating synchronization control data
over the fiber-link.
If the error is logged as an on-board error:
1. Replace the SNI circuit pack.
If the error is logged as an off-board error:
1. Enter
display errors
and follow the associated repair
procedures for FIBER-LK errors.
2. Replace the SNI with this error.
3. Replace the other endpoint of the fiber-link if no DS1C
complex is administered on the fiber-link (use
list fiber-link
to determine whether a DS1C complex is administered). If a
DS1C complex is administered on the fiber-link, replace the
circuit packs in this order:
i
. Replace the DS1C circuit pack connected to this SNI.
ii
.. Replace the other DS1C circuit pack.
iii
.. Replace the other endpoint of the fiber-link.
i. This error indicates a processor complex failure.
1. Replace the SNI circuit pack.
