5.
Disconnect the cables from the PICs on the FPC. If a PIC uses fiber-optic cable,
immediately cover each transceiver and the end of each cable with a rubber safety cap.
Carefully thread each disconnected cable through the hooks in the cable management
system, to prevent the cables from developing stress points.

Unscrew the thumbscrew at each end of the FPC, using a Phillips screwdriver if
necessary.

Pull the ends of the extractor clips, which are adjacent to the thumbscrews, outward
toward the ends of the FPC (see Figure 75).

8.
Grasp the FPC with both hands and slide it about halfway out of the chassis.
9.
Place one hand underneath the FPC to support it, and slide it completely out of the
chassis. Set the FPC on the antistatic foam mat prepared in Step 1.

Do not look directly into the ends of fiber-optic cables or
into the transceivers on the PIC faceplate. Single-mode
fiber-optic cable and the PICs that use it (such as ATM and
SONET/SDH interfaces) emit laser light that can damage
your eyes.

Do not leave a transceiver uncovered except when
removing or inserting the cable. The safety cap keeps the
port clean and prevents accidental exposure to laser light.
