A8808 airflow

The chassis and power supplies for the A8808 use separate air aisles. For the power supply section

at the bottom, air flows from front to rear; for the chassis, air flows in through the air intake vents at

the lower rear and front of the chassis, and exhausts out the side air outlets and rear air outlets at the

top of the chassis, as shown in Figure 53.
