POWER SUPPLY AND COOLING 23
Chapter 1
Power Consumption and Cooling
The following table shows the power consumption for a typical configuration based on primary power
consumptions:
One processor (1 x 3.4 GHz Pentium 4 Processor with HT Technology)
One GB memory (2 x 512 MB)
Two hard drives (2 x SATA 40 GB)
CD-ROM drive
PCI-Express Graphics Card (Quadro FX 1300)
One diskette
Monitor
NOTE When you turn off your workstation with the power button on the front panel, the power
consumption falls below 10 W. 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.
System Fans and Airflow
The workstation includes a rear system fan, one processor heatsink fan, plus an optional front system
fan.
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.
