WARNING:
of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected
to a transceiver emit laser light that can damage your eyes.
7. Arrange the cable in the cable management brackets to prevent it from dislodging or 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. Placing fasteners on the loop helps to maintain its shape.
CAUTION:
allow fastened loops of cable to dangle, which stresses the cable at the fastening
point.
CAUTION:
An arc smaller than a few inches in diameter can damage the cable and cause
problems that are difficult to diagnose.
8. Simultaneously turn both the ejector handles counterclockwise to unseat the FPC.
9. Grasp the handles, and slide the FPC straight out of the card cage halfway.
10. Place one hand around the front of the FPC (the PIC housing) and the other hand 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:
to accept the full weight—up to 18 lb (8.2 kg)—as you slide the FPC out of the
chassis.
When the FPC is out of the chassis, do not hold it by the ejector handles, bus
bars, or edge connectors. They cannot support its weight.
Do not stack FPCs 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.
Do not look directly into a fiber-optic transceiver or into the ends
Do not let fiber-optic cable hang free from the connector. Do not
Avoid bending fiber-optic cable beyond its minimum bend radius.
The weight of the FPC is concentrated in the back end. Be prepared
