9. Insert the appropriate cables 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.
10. Press and hold the FPC offline button on the craft interface.
The green LED labeled
OK blinks for about 5 seconds while the Routing Engine
downloads the FPC software, the FPC runs its diagnostics, and the PICs housed in the
FPC are enabled. Router forwarding operations then halt for about 200 ms while the
Packet Forwarding Engine incorporates the memory on the new FPC into the memory
buffers shared by all FPCs. When the FPC is online, the
OK LED lights steadily and you
can release the offline button.
You can also verify correct PIC and FPC functioning by issuing the
show chassis fpc
commands described in “Maintain FPCs and PICs” on page 162.
11. If you are installing multiple FPCs, repeat Steps 2 through 10 for each one. Wait
30 seconds after installing each FPC to allow the FPC and PICs to come online.

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.
