Chassis Ambient Temperature Definition
The chassis fan control system uses intake air temperature as the input for
controlling fan speeds when in Auto Fan Speed mode. Because of this, the
chassis ambient temperature is defined as the temperature that exists just
outside of the fan intake vents on the rear of the chassis. Note that this
temperature may be higher than ambient room temperature depending
on the surrounding equipment and/or blockages present. It is the user’s
responsibility to ensure that this ambient temperature does not exceed the
controlling fan speeds when in Auto Fan Speed mode. Because of this, the
