3. If the PIC has multiple cable connector ports, label the cable connected to each port

so that you can later reconnect the cables correctly.

4. Press and hold the PIC offline button on the FIC until its failure indicator LED lights,

which usually takes about 5 seconds. The failure LED is usually red; for more

information, see the M7i Multiservice Edge Router PIC Guide.

5. Disconnect the cables from the PIC. If the PIC uses fiber-optic cable, immediately

cover each transceiver and the end of each cable with a rubber safety cap.

6. Arrange the cable 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.

7. Pull the right end of the PIC ejector lever away from the PIC faceplate. This disconnects

the PIC from the midplane.

8. Slide the PIC out of the chassis and place it in the electrostatic bag or on the antistatic

mat.

9. If you are not reinstalling a PIC into the empty PIC slot within a short time, install a

blank PIC panel over the slot to maintain proper airflow in the chassis.

Installing an M7i PIC

WARNING: Do not lookdirectly into transceivers or into the ends of fiber-optic

cables connected to a transceiver. Fiber-optic transceivers emit laser light

that can damage your eyes.

CAUTION: When handling fiber-optic transceivers and fiber-optic cable,

observe the following precautions:

•

Do not leave a fiber-optic transceiver uncovered except when inserting or

removing cable. The safety cap keeps the port clean and prevents

accidental exposure to laser light.

•

Do not bend 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.
