System Fans
Four mid-chassis fans provide cooling.
Fan speed is controlled by a system temperature setting in IPMI. If a fan fails, the remaining
fans will ramp up to full speed. 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 chassis cover
while the power is on, and examine the fans to determine which one has failed.
2. Power down the associated node as described in Section 3.1.
3. Remove the node drawer from the chassis.
4. Remove the failed fan's power cable from the backplane.
5. Lift the fan housing up and out of the chassis.
6. Push the fan up from the bottom and out of the top of the housing.
