Juniper Networks MX480 - Manual (Page 222)

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.
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 Junos OS Operational Mode
Commands.
CAUTION: After the OK LED lights steadily, wait at least 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
show chassis fpc pic-status commands described in “Maintaining MX480 FPCs” on page 132
and “Maintaining MX480 PICs” on page 134 .
