Press and hold the FPC online/offline button. The green
begins to blink. Hold the button down until the LED goes out. The LEDs and
online/offline button for each FPC are located directly above it on the craft interface.
Issue the CLI command:

For more information about the command, see show chassis fpc.
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 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.
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 you are removing a Type 2 or a Type 3 FPC, loosen the screws inside the ejector
6.
handles at the top and bottom of the FPC faceplate.
Simultaneously turn both the ejector handles counterclockwise to unseat the FPC.
7.
Grasp the handles and slide the FPC straight out of the card cage halfway.
8.
Place one hand around the front of the FPC (the PIC housing) and the other hand
9.
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 19 lb (8.6 kg)—as you slide the
FPC out of the chassis.
