Cooling Zones and Airflow Clearance

Note – Proper airflow into and out of the server is essential for keeping the server's
internal temperatures within a safe operating range.
The server contains two pressurized cooling zones: the main cooling zone and the
power supply cooling zone. In the main cooling zone, six fans, arranged in two
redundant rows, cool the motherboard, memory risers, and I/O cards. In the power
supply cooling zone, the rear power supply fans cool the power supplies and the
front drive bays. The server must maintain a pressurized plastic dividing wall seal so
that the power supply fans can draw air through the front drive bays.
The server draws cool air from the front of the server and expels hot air out the rear.
