5.5 Chassis Installation
5.5.1 Airflow
WARNING:
Airflow is critical to the cooling of the CPU and other onboard
components. The chassis in which the PICOe-9452 must have air
vents to allow cool air to move into the system and hot air to move out.
The PICOe-9452 must be installed in a chassis with ventilation holes on the sides allowing
airflow to travel through the heat sink surface. In a system with an individual power supply
unit, the cooling fan of a power supply can also help generate airflow through the board
surface.
