Juniper MX240 - Figure 94: Installing an FPC

12. 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. 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 arcsmaller than a few inches in diameter can damage the cable
and cause problems that are difficult to diagnose.
13. 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 lightssteadily, waitat least 30 secondsbefore
removing the FPC again, removing an FPC from a differentslot, 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 described in “Maintaining MX240 FPCs” on page 387
and “Maintaining MX240 PICs” on page 395.
