the boards to work properly. The heat dissipation system is composed of a fan frame, an air
intake vent, an air exhaust vent, and an air channel. All the fans in the fan frame work
simultaneously, and their rotation speeds can be adjusted by area. When one fan fails, the heat
dissipation system can still allow the device to work at an ambient temperature of 40°C (104°
F) for a short period. The temperature sensors, which are located on the air exhaust vent and
boards, monitor the temperatures of the components on the boards and adjust the fan rotation
speeds according to the commands delivered by the MPU to control the board temperatures.

3.3.2 Fan Module
The air intake vent of the CX600-X2-M16 is 8 U ( 311.15 mm or 12.25 in. )high and 220 mm
( 8.66 in. ) deep.
There are six fans in the fan frame of the CX600-X2-M16. When one fan fails, the device can
still work at the ambient temperature of 40°C ( 104°F ) for a short period.
The rotation speeds of the fans can be adjusted based on the device temperature.
