Also, when installing the chassis in Telco-type racks, ensure that the rack is secured to the floor or
otherwise stabilized. Center-mount the chassis if possible (and practical for your installation). Doing
so places the center of gravity closest to the center of the mounting posts. Figure 8 shows the center
of gravity for both center-mounted and flush-mounted installations. (The center of gravity will shift
somewhat depending on which end of the chassis is positioned at the front of the rack.)

As an alternative, you can install an equipment shelf in the rack if both the rack dimensions allow
the router to be secured to the shelf, and the overall configuration permits safe installation and
access. If you install a customized shelf or install the router on slides, be aware of potential hazards
of tip-over from an unbalanced rack.
To prevent bodily injury when mounting or servicing this unit in a rack, you must take
Warning
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. (For translations of this safety warning, refer to the section
"Chassis Warning—Rack-Mounting and Servicing" on page 35.)
Do not use a ramp inclined at more than 10 degrees. (For translations of this safety
