System Fan
System fans are required for the cooling in the system. Please make sure that the chassis top cover is properly installed in order for the cooling air to circulate properly through the chassis and cool the system and components.
If a fan fails, the ambient air temperature in the chassis will rise. Replace any failed fan immediately.
Replacing the Simple-Swap Fan
Step 1: Remove the cover. Unplug the fan connector and remove the failed fan. Step 2: Align the mounting holes on the fan bar with the fan mounts on the replacement fan. Step 3: Gently place the fan on the fan bar. Make sure the fan is well seated.
Step 4: Plug the fan wires into the correct fan header.
Power Supply
This system has a single 315 watt power supply and can accommodate one AC power supply in the bay at the rear of the chassis. There is no power supply redundancy so if the power supply unit fails, the system will shut down and the user will need to replace the power supply unit.
