Carefully plug the fiber optic cables through the access slot
on the front of the base and into the fiber optic connectors
located on the front of the mast.
Two of the cables are marked UPPER and two are marked
LOWER; plug the two UPPER cables into the connectors
marked U on the mast, and plus the two LOWER cables into
the connectors marked L.
Either UPPER cable can be plugged into either of the
U connectors; either LOWER cable can be plugged into
either of the L connectors.
When completely plugged in, the outer flange on the cable
should be flush with the surface of the mast.
Always use the flange on the cable to connect or disconnect
the fiber optic cables; never pull or push the fiber optic cable
using the collar or the cable.
