On the MPC, pull the ejector lever that is adjacent to the MIC you are installing away
4.
from the MPC faceplate.
Align the rear of the MIC with the guides located at the corners of the MIC slot.
5.
Slide the MIC into the MPC until it is firmly seated in the MPC.
6.
CAUTION: Slide the MIC straight into the slot to avoid damaging the
components on the MIC.
Verify that the ejector lever is engaged by pushing it toward the MPC faceplate.
7.
If the MIC uses fiber-optic cable, remove the rubber safety cap from each transceiver
8.
and the end of each 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.
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.
Insert the appropriate cables into the cable connectors on the MIC.
9.
Arrange each cable to prevent the cable from dislodging or developing stress points.
10.
Secure 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: 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.
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.
Use one of the following methods to bring the MIC online:
