Label the cables connected to each PIC on the FPC so that you can later reconnect
3.
the cables to the correct PICs.
Use one of the following methods to take the FPC offline:
4.
Press and hold the FPC online/offline button. The green
begins to blink. Hold the button down until the LED goes off. The LEDs and
online/offline button for each FPC are located directly above it on the craft interface.
Issue the following CLI command:
user@host>request chassis fpc slot slot-number offline
For more information about the command, see the
NOTE: The slot number corresponds to the lowest numbered slot for
which the FPC is installed.
Disconnect the cables from the PICs installed in the FPC.
5.
Immediately cover each fiber-optic transceiver and the end of each fiber-optic cable
6.
with a rubber safety cap.
WARNING: Do not look directly into a fiber-optic transceiver or into the
ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables
connected to a transceiver emit laser light that can damage your eyes.
Arrange the cable in the cable management brackets to prevent it from dislodging or
7.
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 arc smaller than a few inches in diameter can damage the cable
and cause problems that are difficult to diagnose.
Simultaneously turn both the ejector handles counterclockwise to unseat the FPC.
8.
Grasp the handles, and slide the FPC straight out of the card cage halfway.
