6. Lift the DPC into place, and carefully align the sides of the DPC with the guides inside
the card cage.
7. Slide the DPC all the way into the card cage until you feel resistance.
8. Grasp both ejector handles, and rotate them clockwise simultaneously until the DPC
is fully seated.
9. Remove the rubber safety cap from each fiber-optic transceiver and 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.
10. Insert the cables into the cable connector ports on each DPC (see
Figure 93 on page 237).
11. Arrange the cable in the standard or extended cable manager to prevent it from
dislodging or developing stress points. Secure the cable so that it is not supporting its
own weight 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 arcsmaller than a few inches in diameter can damage the 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 CLI Explorer.
