System Cooling
The chassis contains eight mid-chassis fans and two air shrouds to direct air flow. It also
allows adding up to three optional exhaust fans (MCP-240-84807-0N).
Mid-Chassis Fans
The chassis contains eight 9-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 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.
