Disconnect the cables from the MIC. If the MIC uses fiber-optic cable, immediately
5.
cover each transceiver and the end of each cable 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.
CAUTION: Do not leave a fiber-optic transceiver uncovered except when
you are inserting or removing cable. The safety cap keeps the port clean
and prevents accidental exposure to laser light.
Arrange the cable to prevent it from dislodging or developing stress points. Secure
6.
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.
CAUTION: Avoid bending a 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.
On the MPC, pull the ejector lever that is adjacent to the MIC you are removing away
7.
from the MPC faceplate. Pulling the ejector lever disconnects the MIC from the MPC.
NOTE: To remove a dual-wide MIC that takes up both MIC slots, you must
pull both ejector levers away from the MPC faceplate.
Grasp the handles on the MIC faceplate, and slide the MIC out of the MPC card carrier.
8.
Place it in the electrostatic bag or on the antistatic mat.
If you are not reinstalling a MIC into the emptied MIC slot within a short time, install
9.
a blank MIC panel over the slot to maintain proper airflow in the MPC card cage.
