CAUTION: Avoid bending fiber-optic cable beyond its minimum bend
radius.An arc smaller than a few inches in diametercan damage the cable
and cause problems that are difficult to diagnose.
5. If necessary, remove each installed PIC from the FPC.
6. After you remove each PIC, immediately place it on an antistatic mat or in an
electrostatic bag.
7. Simultaneously turn both the ejector handles counterclockwise to unseat the FPC.
8. Grasp the handles and slide the FPC straight out of the card cage halfway.
9. 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: The weight of the FPC is concentrated in the back end. Be
prepared to accept the full weight—up to 30 lb (13.6 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.
10. If you are not reinstalling a FPC into the emptied FPC slot within a short time, install
a blank FPC panel over the slot to maintain proper airflow in the FPC card cage.
CAUTION: After removing an FPC from the chassis, wait at least 30
seconds before reinserting it, removing an FPC from a different slot, or
inserting an FPC into a different slot.
