After installing the router into the rack as described in "Installing the M40e Router Using
a Mechanical Lift" on page 81 or "Installing the M40e Chassis into the Rack" on page 95,
complete the installation by connecting management and alarm devices, PICs, and power
cables.
Now connect PICs to the network by plugging in network cable. To connect cable to the
PICs (see Figure 69 on page 117, which shows a fiber-optic PIC):
Have ready a length of the type of cable used by the PIC. For cable specifications, see

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.
