FPC Installation Instructions
15
Replace an FPC in an M40 Router
6. If any of the PICs on the FPC connect to fiber-optic cable, remove the rubber safety cap
from each transceiver and each cable.
7. Insert the appropriate cable into the cable connector ports on each PIC on the FPC.
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.
8. If installing multiple FPCs, repeat Steps 2 through 7 for each one. Wait 30 seconds after
installing each FPC to allow the FPC and PICs to come online.

Do not look directly into the ends of fiber-optic cables or
into the transceivers on the PIC faceplate. Single-mode
fiber-optic cable and the PICs that use it (such as ATM and
SONET/SDH interfaces) emit laser light that can damage
your eyes.
Do not let cable hang free from the connector. Do not
allow fastened loops of cable to dangle from the ladder
rack, because this stresses the cable at the fastening point.
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.
