Disconnect the cables from the MICs installed in the MPC.

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.
If a MIC uses fiber-optic cable, immediately cover each transceiver and the end of
6.
each cable with a rubber safety cap.
Arrange the disconnected cables in the cable management brackets to prevent the
7.
cables from developing stress points.
Simultaneously turn both the ejector handles counterclockwise to unseat the MPC.
8.
Grasp the handles, and slide the MPC straight out of the card cage halfway. See

Figure 49 on page 121.
Figure 49: Removing an MPC
Place one hand around the front of the MPC (the MIC housing) and the other hand
10.
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.
