NTP- D95 Upgrade Optical Spans Manually
Figure 12-2 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 4 through 5 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.

(one at each end of the span) who can communicate with each other
during the upgrade.
