Span Upgrade Wizard
Caution
As indicated by the wizard, when installing cards you must wait for the cards to boot up and become
active before proceeding to the next step.
Note
If you install STM-64 cards, a disabled STM-64 laser causes an LOS alarm to be reported for
each STM-64 slot. Enable the STM-64 laser by setting the safety key lock on the STM-64
faceplate to the ON position (labeled 1).
Note
Remember to attach the fiber after installing the STM-N cards.
Step 6
Repeat Steps
through
for additional spans in the ring.
Note
The span upgrade process resets the line’s CV-L threshold to factory default. The CV-L threshold
is reset because the threshold is dependent on line rate.
Stop. You have completed this procedure.
