Rack-Mounting the Chassis
This section describes how to rack-mount the chassis. The universal gateway arrives with 19-inch
rack-mount brackets and larger brackets for use with a 23- or 24-inch rack (See Figure 3-2).
The following information will help you plan your equipment rack configuration:
•Enclosed racks must have ad equate ventilation. Ensu re that the rack is no t congested, because ea ch
unit generates heat. An enclosed rack should h ave lo u ver ed si de s an d a f an to p rovid e co ol in g air.
Heat generated by equipment ne ar the bottom of th e rack can be draw n upward into th e intake ports
of the equipment above.
•When mounting a chas si s in a n op en r ack , en sur e t h at th e r ac k frame does not blo ck th e i ntake or
exhaust ports. If the chassis is installed on slides, check the position of the chassis when it is seated
in the rack.
•Baffles can isolate exhaust air from intake air, which also helps to draw cooling air through the
chassis. The best pla cement of the baffl es depends on the airflow patterns in the rack, which can be
found by experimenting with different configurations.

Before working on a chassis or working near power supplies, unplug the power cord on AC units;
disconnect the power at the circuit breaker on DC units. To see translations of the warnings that
