radiation. Eye damage may occur if beam is viewed directly
or with improper optical instruments. Avoid direct exposure
to the beam.

CAUTION:
An automatic protection switch service hit may occur when
the correct optical fibers are cut. Cutting the wrong fiber lines
will cause a service interruption.
At the point where the new DDM-2000 OC-12 shelf will be added,
use local procedures to cut the two fiber lines connecting the
existing OC-3 shelf at the CO with the adjacent OC-3 shelf
equipped with both 24/29-Type OLIUs. Condition the fiber for
connection to the new shelf.
