Figure 3-18. Replacing a Rear System Fan
System Cooling
The chassis contains fourteen fans, a heatsink for each CPU, and an air shroud to direct air
flow.
Fans
The chassis contains eight 9-cm and six 8-cm high-performance fans. 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 will continue to run with a failed fan, although it may shut down if
the heat gets too great. Replace any failed fan at your earliest convenience with the same
model. Failed fans can be identified through the IPMI.
Changing a System Fan
1. Determine which fan has failed using IPMI, or check by observation.
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. Note that the fan module top is labelled.
4.
Check that the fan is working properly and that the LED on the control panel is off.
