Each FPC slot not occupied by an FPC must be covered by an FPC blank panel. An FPC blank panel
weighs 6.9 lb (3.1 kg).
To remove an FPC (see Figure
1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to
one of the ESD points on the chassis.
3. Use one of the following methods to take the FPC offline:
• Press and hold the FPC online/offline button. The green OK LED next to the button begins to
blink. Hold the button down until the LED goes out.
• Issue the following CLI command:
user@host>request chassis fpc slot
4. Disconnect the cables from the PICs installed in the FPC. Immediately cover each transceiver and
the end of each cable with a rubber safety cap. Arrange the disconnected cables in the cable
management system, to prevent the cables from developing stress points.
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.
CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting
or removing cable. The safety cap keeps the port clean and prevents accidental
exposure to laser light.
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.
5. If necessary, remove each installed PIC from the FPC.
6. After you remove each PIC, immediately place it on an antistatic mat or in an electrostatic bag.
7. 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.
