Setting the Chassis on a Desktop

Rack-Mounting the Chassis


Warning When installing the unit, the ground connection must always be made first and disconnected last. To see translations of the warnings that appear in the publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.



Warning This unit is intended for installation in restricted access areas. A restricted access area is where access can only be gained by service personnel through the use of a special tool, lock and key, or other means of security, and is controlled by the authority responsible for the location. To see translations of the warnings that appear in the publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.


Setting the Chassis on a Desktop

The location of the chassis is extremely important for proper operation. Equipment placed too close together, inadequate ventilation, and inaccessible panels can cause malfunctions and shutdowns, and can make maintenance difficult. The following information will help you plan the location of the chassis:

Plan for access to both front and rear panels of the chassis.

Ensure that the room where the chassis operates has adequate ventilation. Remember that electrical equipment generates heat. Ambient air temperature may not cool equipment to acceptable operating temperatures without adequate ventilation.

Attaching the Rubber Feet

To attach the rubber feet to the chassis, follow this procedure:


Step 1 Carefully turn the chassis over so you can see the four small depressions made for attaching the rubber feet. (See Figure 3-1.) The rubber feet are included in the accessory kit that shipped with your universal gateway.

Step 2 Remove the wax paper from the bottom of each rubber foot and press the foot into the small depression on the bottom of the chassis. (See Figure 3-1.)

Figure 3-1 Attaching the Rubber Feet


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 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.


Warning 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 appear in the publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.
