System Fans

There are four hot-swap fans that provide cooling. Each fan 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. Although the system can continue to run with a failed fan,
replace any failed fan at your earliest convenience with the same type and model.
Changing a System Fan
1. Determine which fan is failing. If possible, use IPMI. If not, remove the top and front
chassis cover while the power is on, and examine the fans to determine which one has
failed.
2. Pull the fan out of the chassis.
3. Place the replacement fan into the vacant space in the housing while making sure the
arrows on the top of the fan (indicating air direction) point in the same direction as the
arrows on the other fans.
4. Confirm that the fan is working properly before replacing the chassis cover.
