Input Power Consumption
Typical operating mode (system busy)
Windows XP Idle
Standby mode (S3)
Hibernate mode (S4)
Power Off (S5)
NOTE: To reach zero power consumption, either unplug the workstation from the power outlet or use a power strip with
a switch. However, removing all power to the workstation might reduce the life of the real-time clock battery.
For more information on power-saving features, refer to your operating system documentation.

1.4.4 System Fans and Airflow

The workstation includes a rear system fan, one processor heatsink fan, one power supply fan, plus an optional front
system fan.

1.4.5 Resetting the Power Supply

If an overload triggers the power supply overload protection, all power is immediately cut. 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.
