Fans

Fan speed is controlled by a system temperature setting in BMC. 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 BMC. If not, remove the chassis cover
while the power is on, and examine the fans to determine which one has failed.
2. Remove power from the system as described in Section 3.1.
3. Remove the fan cable from the backplane for the failed fan and the adjacent fan.
4. Lift the fan housing up and out of the chassis.
5. Push the fan up from the bottom and out of the top of the housing.
