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 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 MX240 MPCs” on
page 393 and “Maintaining MX240 MICs” on page 393.
