Fans
The system has five hot-swap 8-cm exhaust fans accessible from the rear of the chassis.
They can be removed or replaces individually by pinching the top and bottom release tabs.
One or two fans should be removed to install or replace memory or PCI expansion cards.
Fan speed is controlled by a system temperature setting in the BMC. If a fan fails, the
remaining fans will ramp up to full speed, and the system can continue to operate. Replace
any failed fan at your earliest convenience with the same type and model.
Removing or Replacing a System Fan
1. While the system is running, examine the fans to determine which fan has failed.
2. Pinch together the upper and lower release tabs and pull the fan out of the bay.

Caution:
Fans will continue to rotate for a brief time after removing them from the chassis.
To avoid injury, keep fingers clear of the rotating fan blades.
3.
Slide the new fan into the vacant bay. Confirm that the fan is fully seated in the bay and
functioning.
