Juniper Networks MX480 - Manual (Page 224)

• Press its online/offline button. For a PIC installed in FPC3, use a narrow-ended tool
that fits inside the opening that leads to the button. Press and hold the button until
the PIC LED goes off (about 5 seconds).
• Issue the following CLI command:
user@host> request chassis pic fpc-slot fpc-slot pic-slot pic-slot offline
For more information about the command, see the Junos OS Operational Mode
Commands.
4. Label the cables connected to the PIC so that you can later reconnect each cable to
the correct PIC.
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.
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.
6. Arrange the cable in the cable management brackets 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: 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.
7. For an FPC3 PIC, loosen the captive screw at the bottom of the PIC faceplate, then
twist the ejector handle at the top of the faceplate counterclockwise to unseat the
PIC.
8. Slide the PIC out of the FPC card carrier and place it in the electrostatic bag or on the
antistatic mat.
9. If you are not reinstalling a PIC into the emptied PIC slot within a short time, install a
blank PIC panel over the slot to maintain proper airflow in the FPC card cage.
