This section describes how to rack-mount the chassis. The universal gateway arrives with 19-inch 
(48.26-cm) rack-mount brackets and larger brackets for use with a 23- (58.429-) or 24-inch (60.96-cm) 
rack (See 

The following information will help you plan your equipment rack configuration:

Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because each 
unit generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. 
Heat generated by equipment near the bottom of the rack can be drawn upward into the intake ports 
of the equipment above. 

When mounting a chassis in an open rack, ensure that the rack frame does not block the intake 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 placement of the baffles 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. Statement 12
