NOTE: When you power down your workstation with the power button on the front panel, the power
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 a rear system fan, one memory fan, one CPU heatsink fan, one power supply
fan, plus an optional front system fan is available for special considerations.
Resetting the power supply
If an overload triggers the power supply overload protection, all power is immediately disconnected. To
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.
When you power down the workstation through the operating system, power consumption falls below
the low power consumption but does not reach zero. This on/off feature extends the life of the power
supply.
