Lift the FPC into place and carefully align first the bottom, then the top of the FPC

with the guides inside the card cage. Be sure the FPC is right-side up, with the
components on the right of the FPC.
CAUTION: 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.
Slide the FPC all the way into the card cage until you feel resistance.

turn both ejector handles clockwise to seat the FPC.
If any of the PICs on the FPC connect to fiber-optic cable, remove the rubber safety

cap from each transceiver and cable.
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.
Insert the appropriate cable into the cable connector ports on each PIC on the FPC.
11.
Secure the cables so that they are not supporting their own weight. Place excess cable
out of the way in a neatly coiled loop, using the cable management system. Placing
fasteners on a loop helps to maintain its shape.
CAUTION: Do not let fiber-optic cable hang free from the connector. Do
not allow fastened loops of cable to dangle, which stresses the cable at
the fastening point.
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.
Use one of the following methods to bring the FPC online:
