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 further.
16. Remove the rubber safety cap from each fiber-optic transceiver and fiber-optic cable.
LASER 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 diameter can 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
begins to blink, in about 5 seconds.
• Issue the following CLI command:
user@host> request chassis fpc slot
