Removing an M320 PIC Cable

Removing and installing PIC cables do not affect router function, except that a PIC does
not receive or transmit data while its cable is disconnected.
To remove a PIC cable:
If the PIC connects to fiber-optic cable, have ready a rubber safety cap for each cable
1.
and transceiver.
If removing all cables connected to the PIC, use one of the following methods to take
2.
the PIC offline:
Press its online/offline button. For a PIC installed in an FPC1, use a tool—such as a
flat-blade screwdriver—to press the button slightly beneath the faceplate of the
PIC. For a PIC installed in an FPC2 or 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 out (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 System Basics and
Services Command Reference.
Unplug the cable from the cable connector port. If the PIC uses fiber-optic cable,
3.
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
inserting or removing cable. The safety cap keeps the port clean and
prevents accidental exposure to laser light.
Remove the cable from the cable management system and detach it from the
4.
destination port.
