Removing a T1600 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 Type 1 PIC, use a tool—such as a flat-blade
screwdriver—to press the button slightly beneath the faceplate of the PIC. For a
Type 2 , Type 3, or Type 4 PIC, 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.

Installing a T1600 PIC Cable

To install a PIC cable (see Figure 142 on page 252):
Have ready a length of the type of cable used by the PIC. For cable specifications, see
