Align the rear bottom corners of the FPC with the guides at the bottom of the FPC

slot. Slide the FPC into the card cage until it contacts the midplane.
Push the ends of the ejector levers inward until they are nearly flush with the face of
5.
the FPC.
Tighten the thumbscrew at each end of the FPC to seat the FPC securely in the chassis.
6.
For each different PIC you install in the FPC:
7.
If the PIC uses fiber-optic cable, verify that there is a rubber safety cap over each
a.
transceiver on the faceplate. Install a cap if necessary.
Slide the PIC into a slot in the FPC, aligning the notches in the connector at the rear
b.
of the PIC with the notches in the FPC slot and then firmly pushing the PIC into
place.
CAUTION: Insert the PIC straight into the FPC slot to avoid damaging
the components on the bottom of the PIC.
Tighten the thumbscrews at the ends of the PIC faceplate simultaneously and at
c.
about the same rate (tightening the two screws alternately or at very different
rates can cause the PIC to become lodged in the FPC slot, making it difficult to
turn the screws). Verify that the PIC is seated properly.
If any of the PICs on the FPC connect to fiber-optic cable, remove the rubber safety
8.
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.
9.
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:
