12. Insert the appropriate cable into the cable connector ports on each PIC on the FPC.
13. Arrange the cable in the cable management brackets to prevent it from dislodging or
developing stress points. Secure the cable so that it is not supporting its own weight
as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop.
Placing fasteners on the 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 smallerthan a few inches in diameter can damage the cable
and cause problems that are difficult to diagnose.
14. Use one of the following methods to bring the FPC online:
•
Press and hold the FPC online/offline button until the green OK LED next to the
button lights steadily, in about 5 seconds. The LEDs and online/offline button for
each FPC are located directly above it on the craft interface.
•
Issue the following CLI command:
user@host>request chassis fpc slot slot-number online
For more information about the command, see the CLI Explorer.
CAUTION: Afterthe OK LED lights steadily, wait atleast 30 seconds before
removing the FPC again,removing an FPC from a different slot, or inserting
an FPC in a different slot.
You can also verify correct FPC and PIC functioning by issuing the show chassis fpc and
showchassis fpc pic-status commands describedin “Maintaining MX480 FPCs”on page425
and “Maintaining MX480 PICs” on page 433.
