8. If the MIC uses fiber-optic cable, remove the rubber safety cap from each transceiver 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 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.
9. Insert the appropriate cables into the cable connectors on the MIC.
10. Arrange each cable to prevent the cable 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.
CAUTION: Do not let fiber-optic cables hang free from the connector. Do not
allow the fastened loops of a cable to dangle, which stresses the cable at the
fastening point.
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.
11. Power on the services gateway. The OK LED on the power supply faceplate should blink, then light
steadily.
12. Verify that the MPC and MICs are functioning correctly by issuing the show chassis fpc and show
chassis fpc pic-status commands.
