C3000 and C5000 Fan Module Description
The C3000 and C5000 Controllers have three individual cooling fan modules that work together to keep all components within the acceptable temperature range. The fan modules install in the rear of the controller and are hot-swappable.
The air intake is located on the front sides of the chassis. Air is pulled through the chassis and is exhausted out the rear by the fans. The power supplies are self-cooling and are located in the rear of the controller to the right of the fans. The exhaust for the power supplies is located on the right side of the rear of the chassis.

The chassis monitors the temperature of the components. When the controller is operating normally, the fan modules function at lower than full speed. If a fan module fails or the ambient temperature rises above a threshold, the speed of the remaining fan modules is automatically adjusted to keep the temperature within the acceptable range. If the ambient maximum temperature specification is exceeded and the system cannot be adequately cooled, the system shuts down by disabling output power from each power supply.
