The router holds up to eight FPCs, which are installed vertically in the front of the router.
An empty FPC weighs approximately 25 lb (11.3 kg), and an FPC with PICs installed can
weigh up to 33.5 lb (15.1 kg).
Each FPC slot not occupied by an FPC must be covered by an FPC blank panel. An FPC
blank panel weighs 9 lb (4.2 kg).

Disconnect the cables from the PICs installed in the FPC. If a PIC uses fiber-optic

cable, immediately cover each transceiver and the end of each cable with a rubber
safety cap. Arrange the disconnected cables in the cable management system, to
prevent the cables from developing stress points.
WARNING: Do not look directly into a fiber-optic transceiver or into the
ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable
connected to a transceiver emit laser light that can damage your eyes.
CAUTION: Do not leave a fiber-optic transceiver uncovered except when
inserting or removing cable. The safety cap keeps the port clean and
prevents accidental exposure to laser light.
CAUTION: Avoid bending fiber-optic cable beyond its minimum bend
radius. An arc smaller than a few inches in diameter can damage the cable
and cause problems that are difficult to diagnose.
