Disconnect the cables from the PICs installed in the FPC. If a PIC uses fiber-optic
5.
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.
If necessary, remove each installed PIC from the FPC.
6.
After you remove each PIC, immediately place it on an antistatic mat or in an
7.
electrostatic bag.
Do not stack components on top of one another after removal. Place each one
individually in an electrostatic bag or on its own antistatic mat on a flat, stable surface.
Simultaneously turn both the ejector handles counterclockwise to unseat the FPC.
8.
Grasp the handles, and slide the FPC straight out of the card cage halfway.
9.
Place one hand around the front of the FPC (the PIC housing) and the other hand
10.
under it to support it. Slide the FPC completely out of the chassis, and place it on the
antistatic mat or in the electrostatic bag.
CAUTION: The weight of the FPC is concentrated in the back end. Be
prepared to accept the full weight—up to 33.5 lb (15.1 kg)—as you slide
the FPC out of the chassis.
