Cooling

There are six system fans assemblies that cool the server. The fans are redundant, hot-swappable, and
interchangeable. You service the fans through the top and rear of the chassis. The fans are N+1, meaning that

reached, the server automatically shuts down to prevent an overtemperature condition.
General Airflow
Airflow enters through the front and exhausts out the rear. Airflow baffles may be required to optimize air
circulation within the enclosure. Fans are monitored by the system to indicate performance.

fan units in the upper zone along with two power supplies that provide their own individual cooling.
