3.10 Fans
Six hot swappable fans are mounted in a fan gantry that is located in the chassis behind the
processors. Each fan has a blind mate 2x2 connector that plugs directly into the CPU Board. There is
an additional fan integrated in each power supply to cool the power supply subsystem and also
provide additional cooling for the whole system.
The Embedded Server Management logic in the system monitors the speed of the fans. A fan failure
or over-temperature in the system results in a notification by iDRAC6. All system fans are pulse width
modulated fans. Redundant cooling is supported with one fan failing at a time.
