Changing a System Fan
1. If necessary, open the chassis while the system is running to determine which
fan has failed. Never run the server for an extended period of time with the
chassis cover open.
2. Unplug the fan cable from the serverboard and remove the failed fan from the
chassis.
3. Replace the failed fan with an identical 4cm fan, available from Supermicro.
4. Push the new 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.
5. Reposition the fan housing back over the two mounting posts in the system, then
reconnect the fan wires to the same fan headers on the serverboard.
6. Power up the system and check that the fan is working properly and that the
LED on the control panel has turned off. Finish by replacing the chassis cover.

6-7 System Cooling
Eight 4-cm counter-rotating fans provide the cooling for the system. Each fan
unit is actually made up of two fans joined back-to-back, which rotate in opposite
directions. This counter-rotating action generates exceptional airflow and works to
dampen vibration levels. Four compound fans come stock with the server, and four
more can be added.
Make sure the chassis top cover makes a good seal so the cooling air circulates
properly through the chassis.
System Fan Replacement
Fan speed is controlled by IPMI depending on the system temperature. 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 model. Failed
fans can be identified through the BIOS. The fan numbers are printed on the floor
of the chassis.
