CAUTION: Take care not to bend or otherwise damage the power
connector prongs.
13. Slowly slide the FPC into the slot until you feel resistance.
14. Align the ejector handles on the FPC faceplate in a position close to horizontal.
15. Simultaneously turn both ejector handles clockwise until you cannot turn them farther.
16. Remove the rubber safety cap from each fiber-optic transceiver and fiber-optic cable.
WARNING: Do not look directly into a fiber-optic transceiver or into the
ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable
connected to a transceiver emit laser light that can damage your eyes.
17. 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. 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 smaller than a few inches in diametercan damage the cable
and cause problems that are difficult to diagnose.
18. 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.
•
Issue the following CLI command:
user@host>request chassis fpc slot slot-number online
For more information about the command, see the Junos OS System Basics and
Services Command Reference.
CAUTION: After the OK LED lights steadily, wait at least 30 seconds before
removing the FPC again, removingan FPC from a differentslot,or inserting
an FPC in a different slot.
