as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop.
Placing fasteners on the 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 smaller than a few inches in diameter can damagethe cable
and cause problems that are difficult to diagnose.
12. Use one of the following methods to bring the DPC online:
•
Press and hold the corresponding DPC online button on the craft interface until the
green OK 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 LED turns green, wait at least 30 seconds before
removing the DPC again, removing a DPC from a different slot, or inserting
a DPC in a different slot.
You can also verify that the DPC is functioning correctly by issuing the show chassis fpc
and show chassis fpc pic-status commands.
