As shown in Figure 1-1, the airflow in the server chassis flows through the mesh grill at the front of the chassis through the power supply, and over the motherboard. The hot air exhausts out the back of the chassis.


Caution: Always keep at least 2 inches (5.1 cm) of clearance at the back of the chassis for cooling.
