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 smallerthan a few inches in diameter can damage the cable
and cause problems that are difficult to diagnose.
6. If a MIC uses fiber-optic cable, immediately cover each transceiver and the end of
each cable with a rubber safety cap.
7. Arrange the disconnected cables in the cable management brackets to prevent the
cables from developing stress points.
8. Simultaneously turn both the ejector handles counterclockwise to unseat the MPC.
9. Grasp the handles, and slide the MPC straight out of the card cage halfway.
10. Place one hand around the front of the MPC (the MIC housing) and the other hand
under it to support it. Slide the MPC completely out of the chassis, and place it on the
antistatic mat or in the electrostatic bag.
CAUTION: The weight of the MPC is concentrated in the back end. Be
prepared to accept the full weight—up to 18.35 lb (8.3 kg)—as you slide
the MPC out of the chassis.
When the MPC is out of the chassis, do not hold it by the ejector handles,
bus bars, or edge connectors. They cannot support its weight.
Do not stack MPCs on top of one another after removal. Place each one
individually in an electrostatic bag or on its own antistatic mat on a flat,
stable surface.
11. If necessary, remove each installed MIC from the MPC.
