System Cooling
Four mid-chassis 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, and the system can continue to operate. Replace any failed
fan at your earliest convenience with the same model.
Replacing a System Fan
1. Identify the failed fan using IPMI. Otherwise, while the system is running, examine the
fans to determine which one has failed.
2. Press the release tab and pull the fan out of the housing.
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.
Place the new fan into the vacant fan bay. Note the air flow direction arrow must point
toward the rear of the chassis. Push down until it clicks into place.
4.
Confirm that the fan is functioning properly.
