For a PIC installed in a Type 1 FPC, use a tool—such as a flat-blade screwdriver—to
press the button slightly beneath the faceplate of the PIC. For a PIC installed in a
Type 2 FPC or Type 3 FPC, use a narrow-ended tool that fits inside the opening that
leads to the button.
Issue the following CLI command:
user@host> request chassis pic fpc-slot fpc-slot pic-slot pic-slot offline
For more information about the command, see request chassis pic.
Label the cables connected to the PIC so that you can later reconnect each cable to
4.
the correct PIC.
Disconnect the cables from the PIC. If the PIC uses fiber-optic cable, immediately
5.
cover each transceiver and the end of each cable with a rubber safety cap.
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.
Arrange the cable in the cable management system to prevent it from dislodging or
6.
developing stress points. Secure the cable so that it is not supporting its own weight
as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop in
the cable management system. Placing fasteners on the loop helps to maintain its
shape.
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.
Unseat the PIC:
7.
Type 1 or Type 2 PIC—Loosen the captive screws at the top and bottom of the PIC
faceplate.
Type 3 PIC—Loosen the captive screw at the bottom of the PIC faceplate, then twist
the ejector handle at the top of the faceplate and counterclockwise to unseat the
PIC.
Type 4 PIC—Twist the ejector handle at the bottom of the PIC faceplate, then twist
the ejector handle at the top of the faceplate and counterclockwise to unseat the
PIC.
