System Cooling

Five hot-swap, heavy-duty rear mounted fans provide cooling. They can be replaced without
powering down the system.
Fan speed is controlled by a system temperature setting in IPMI. If a fan fails, the remaining
fans will ramp up to full speed. Replace any failed fan at your earliest convenience with the
same type and model. The system can continue to run with a failed fan.
Replacing a System Fan
1. While the power is running, examine the fans to determine which fan has failed.
2. Simultaneously press down on the upper release tab and push up the lower release tab
of the failed fan.
3. Pull the fan out of the bay using the tabs.
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.
4. Place the new fan into the vacant fan bay. Confirm that the fan is fully seated in the fan
bay and functioning properly.
