Warning

To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure

that the system remains stable. The following guidelines are provided to ensure your safety:

This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest

component at the bottom of the rack.

If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the

rack. Statement 1006

Warning

To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles on

modules (such as power supplies, fans, or cards); these types of handles are not designed to support the weight

of the unit. Statement 1032

While keeping the brackets flush against the posts or mounting strips, position the router so that the holes in the
