After installing the router into the rack as described in "Installing the M120 Router Using
a Mechanical Lift" on page 55 or "Installing the M120 Router Without Using a Mechanical
Lift" on page 69, complete the installation by connecting management and alarm devices,
PICs, and power cables.
Now connect PICs to the network by plugging in network cables. To connect cable to the
PICs (see Figure 48 on page 88, which shows a fiber-optic PIC):
Have ready a length of the type of cable used by the PIC. For cable specifications, see
1.
the M20 PIC Guide.
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.
3.
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.
