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.
Insert the cable connector into the cable connector port on the PIC faceplate.

Arrange the cable in the cable management system, to prevent it from dislodging or
4.
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 in
the cable management system. Placing fasteners on the loop helps to maintain its
shape.
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.
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.
Insert the other end of the cable into the destination port.
5.
Repeat the previous steps for any additional cables.
6.
If the PIC is offline (its failure indicator LED is lit), use one of the following methods
7.
to bring the PIC online:
Press the PIC offline/online button until the PIC LED lights green. 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.
Issue the following CLI command:
user@host>request chassis pic fpc-slot fpc-slot pic-slot pic-slot online
For more information about the command, see the Junos OS System Basics and
Services Command Reference.
The normal functioning indicator LED confirms that the PIC is online. You can also
verify correct PIC functioning by issuing the
described in "Maintaining T1600 PICs and PIC Cables" on page 166.
