Take each MIC to be installed in the replacement MPC out of its electrostatic bag and
3.
identify the slot on the MPC where it will be connected.
Verify that each fiber-optic MIC has a rubber safety cap covering the MIC transceiver.
4.
If it does not, cover the transceiver with a safety cap.
Install each MIC into the appropriate slot on the MPC.
5.
Locate the slot in the card cage in which you plan to install the MPC.
6.
Orient the MPC so that the faceplate faces you.

the card cage.
CAUTION: 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.
Slide the MPC all the way into the card cage until you feel resistance.
9.
Grasp both ejector handles and rotate them clockwise simultaneously until the MPC

is fully seated.
If any of the MICs on the MPC connect to fiber-optic cable, remove the rubber safety
11.
cap from each 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.
Insert the appropriate cable into the cable connector ports on each MIC on the MPC.
12.
Secure the cables so that they are not supporting their own weight. Placing fasteners
on a 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.
