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
