12. Insert the appropriate cable into the cable connector ports on each MIC on the MPC.
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.
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.
13. Use one of the following methods to bring the MPC online:
•
Press and hold the corresponding MPC online button on the craft interface until the
green OK/FAIL LED next to the button lights steadily, in about 5 seconds.
•
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: After the OK/FAIL LED lights steadily, wait at least 30 seconds
before removing the MPC again, removing an MPC from a different slot,
or inserting an MPC in a different slot.
You can also verify correct MPC and MIC functioning by issuing the show chassis fpc and
show chassis fpc pic-status commands described in“Maintaining MX480 MPCs” on
page 431 and “Maintaining MX480 MICs” on page 430.
