Installing a Cable on an MX5, MX10, MX40, and MX80 MIC
To install a cable:
1. Have ready a length of the type of cable used by the component. For cable
specifications, see the MX Series Interface Module Reference.
2. If the cable connector port is covered by a rubber safety cap, remove the 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 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.
3. Insert the cable connector into the cable connector port on the MIC faceplate.
4. Arrange the cable in the cable management bracket to prevent it from dislodging or
developing stress points. 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.
Placing fasteners on the loop helps to maintain its shape.
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.
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.
5. Insert the other end of the cable into the destination port.
6. Repeat the previous steps for any additional cables.
7. If the MIC is offline (its failure indicator LED is lit), use one of the following methods
to bring it online:
•
Press the MIC offline/online button until the MIC LED lights green.
