Juniper Networks MX480 - Manual (Page 231)

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.
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 Junos OS Operational Mode
Commands.
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 135 and “Maintaining MX480 MICs” on page 137 .
