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 c arrier, replace the SNC.
If two SNCs exist in this switch node carrier, p erform the following
steps:
a. Set the standby SNC to active by running the set
switch-node-clock UUCSS command with the standb y
SNC’s location.
b. If the problem goes aw ay, 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 be low.
c. If the problem p ersists, 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 adjac ent SNIs.
3. Replace the rightmost SNI from the pair of ad jacent SNIs.
4. If none of the above steps cleared this error, this could b e a switch
node carrier backplane problem.
h. This error indicates a failure communic ating synchronization control d ata
over the fiber-link.
If the error is logged as an on-b oard error:
1. Replace the SNI circuit pac k.
If the error is logged as an off-b oard 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 endpoin t 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 i n this order:
i
. Replace the DS1C circuit pac k connected to this SNI.
ii
.. Replace the other DS1C circuit pac k.
iii
.. Replace the other endpoint o f the fiber-link.
i. This error indicates a processor c omplex failure.
1. Replace the SNI circuit pac k.
