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.

For additional information on power-saving features, see your operating system documentation.

System fans and airflow

The workstation includes one rear system fan, one memory fan, one processor (CPU) heatsink fan for

each processor, and one power supply fan, plus optional front system fans.

Resetting the power supply

If an overload triggers the power supply overload protection, all power is immediately shut off. 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 rate but does not reach zero. This on/off feature extends the life of the power

supply.
