Figure 3-13. Replacing a Mid-Chassis Fan
System Cooling
The chassis contains four 8-cm high-performance fans and an air shroud to direct air flow.
Replacing a Mid-Chassis Fan
Fan speed is controlled by IPMI depending on the system temperature. If a fan fails, the
system will continue to run with the remaining fans ramping up to full speed. The system
may start to throttle if the environmental temperature is above the recommended threshold.
Replace any failed fan at your earliest convenience with the same model. Failed fans can
be identified through the IPMI.
Replacing a Mid-Chassis Fan
1. Determine which fan has failed using IPMI, or if necessary, open the chassis while the
system is running. Never run the server for long without the chassis cover.
2. Push the release tab and pull the failed fan from the chassis. Fans can be replaced
while the system is running.
3. Replace the failed fan with an identical fan, available from Supermicro. Push the new
fan into the housing, making sure the air flow direction is the same.
4. Check that the fan is working properly and that the LED on the control panel has turned
off. Finish by replacing the chassis cover.
