14. Enter the update (upd) command using the CIT. If the MAIN 1
update is successful, you will see the following message:
main-2 OLIU not updated - no change in provisioning
The FAULT LED on the 29-type OLIU in MAIN 1 will initially be lit
but should extinguish. This may take up to 5 minutes. The FAULT
LED on MAIN 2(P) OLIU will light. Perform a rtrv-alm and
verify that only a minor alarm "main-2 CP not allowed" is present.
Remotely log in to the connected node and verify that only VT AIS
and/or STS AIS alarms are present. If the update is successful,
proceed to Step 14.
If the MAIN 1 update fails, you will see the message:
main-1 OLIU not updated - OC12 upgrade aborted
followed by one or more descriptive messages indicating the
reason for the failure.
• A "Line Fault" message indicates that the shelf has detected
a degradation of the incoming OC-12 optical signal. Verify the
optical input level and fiber connections and far-end OLIU
before attempting the upgrade procedure again.
• A "Pack Failure" message indicates a problem with the pack.
The upgrade procedure should be re-attempted with a
different 29-type OLIU.
NOTE:
A CP removed alarm will occur in this step when the MAIN
2(P) OLIU is removed. A inc. OC-12 LOS alarm will occur at
the connecting Node.
15. At the starting node, remove optical fibers from MAIN 2(P) OLIU
and lift the faceplate latch, then remove MAIN 2(P) OLIU.
