consumption falls below 10 W. To reach zero power consumption, unplug the workstation from the power
outlet or use a power strip with a switch. For additional information on power-saving features, see your
operating system documentation.

System fans

The workstation includes two rear system fans, one memory fan, one CPU heatsink fan for each
processor, and one power supply fan. An optional front system fan is available for special considerations.

Resetting the power supply

reset the power supply unit:
1. Disconnect the power cord.
2. Determine what caused the overload and fix the problem.
3. Reconnect the power cord and reboot the workstation.
