Connecting PIC Cables to the T640 Router

The router supports PICs that use various kinds of network cable, including multimode
and single-mode fiber-optic cable. For information about the type of cable used by each
PIC, see the PIC guide for your router.
You connect PICs to the network by plugging in network cable. To connect cable to the
PICs (see Figure 89 on page
Have ready a length of the type of cable used by the PIC. For cable specifications, see

If the PIC cable connector port is covered by a rubber safety plug, remove the plug.

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

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.
