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 cables
connected to a transceiver emit laser light that can damage your eyes.
CAUTION: Do not leave a fiber-optic transceiver uncovered except when
you are inserting or removing cable. The safety cap keeps the port clean
and prevents accidental exposure to laser light.
Arrange the cable to prevent it from dislodging or developing stress points. Secure
6.
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.
CAUTION: Avoid bending a 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.
For an FPC3 PIC, loosen the captive screw at the bottom of the PIC faceplate, then
7.
twist the ejector handle at the top of the faceplate counterclockwise to unseat the
PIC.
Slide the PIC out of the FPC card carrier and place it in the electrostatic bag or on the
8.
antistatic mat.
If you are not reinstalling a PIC into the emptied PIC slot within a short time, install a
9.
blank PIC panel over the slot to maintain proper airflow in the FPC card cage.
