System fans This workstation includes one rear system fan, one processor heatsink fan, and one power supply fan. In addition, an optional front system fan is available for special environments, and some graphics cards include onboard fans. Resetting the power supply If an overload triggers the power supply overload protection, all power is immediately disconnected. To reset the power supply: 1. Disconnect the power cord from the workstation.. 2. Determine what caused the overload and fix the problem. See System diagnostics and troubleshooting on page 107 for troubleshooting information. 3. Reconnect the power cord and reboot the workstation. When you power off the workstation through the operating system, power consumption falls below what is considered low power consumption, but does not reach zero. This low power consumption feature extends the life of the power supply. Environmental specifications This section describes the environmental specifications of your workstation.
