Site Requirements for the Sentriant NG Appliance

The Sentriant NG appliance can be rack-mounted in a standard 19-inch rack.
Be sure to locate the system away from heat sources and in an area that provides unobstructed air flow
to the chassis cooling vents. The chassis intake ambient air temperature should not exceed 95 ºF (35 ºC)
or drop below 41ºF (5º C).
CAUTION
Do not place a monitor or other object on top of the system. The mounting brackets and chassis cover are not
designed to support additional weight.
Make sure that the voltage and frequency of the power source matches the electrical ratings of the
Sentriant NG appliance, and that the building and/or power source provides overload protection.
In regions that are susceptible to electrical storms, we recommend that you plug your system into a
surge suppressor.

Rack Ventilation Requirements

Make sure that there is a minimum of 3 inches of airspace at the back of the chassis.
Open-type racks should meet the manufacturer's recommended ventilation requirements.
Enclosed-type racks should have a louvered front and back with a fan to dissipate heat generated by
equipment mounted in the rack.
If you are installing the Sentriant NG appliance in enclosed racks with top-mounted ventilation fans,
make sure that there is adequate ventilation for the racks. Heat generated by equipment mounted in
the bottom of the rack can be drawn up into equipment mounted in the top of the rack.
Chassis intake ambient air temperature should not exceed 95º F (35º C).
Operating humidity should be kept between 10% and 95% relative humidity (noncondensing).
