System fans The workstation includes a rear chassis fan, one processor heatsink fan, and one power supply fan. An optional front PCI fan is available for special considerations, such as graphics PCI cards. 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 correct the problem. 3. Reconnect the power cord, apply power, and reboot the workstation. NOTE: When you power down your workstation with the power button on the front panel, the power consumption falls below 10W. To reach zero power consumption, remove power from the workstation. For additional information on power-saving features, see your operating system documentation. Environmental specifications This section describes environmental specifications of your workstation.
