If a PIC uses fiber-optic cable, immediately cover each transceiver and the end of each
6.
cable with a rubber safety cap. Arrange the disconnected cables in the cable manager
to prevent the cables from developing stress points.
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 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.
If necessary, remove each installed PIC from the FPC.
10.
After you remove each PIC, immediately place it on an antistatic mat or in an
11.
electrostatic bag.
If you are not reinstalling an FPC into the emptied DPC slots within a short time, install
12.
a blank DPC panel over each slot to maintain proper airflow in the card cage.
CAUTION: After removing an FPC from the chassis, wait at least 30
seconds before reinserting it or inserting an FPC into a different slot.
