WARNING:
Unterminated optical connectors may emit invisible laser
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 shelf will be added, use
local procedures to cut the two fiber lines connecting existing
shelves and condition the fiber for connection to the new shelf.
