18 Chapter 1 Hardware overview

Ensuring proper ventilation

Proper ventilation for the system is important for workstation operation. Follow these guidelines:
Operate the workstation on a sturdy, level surface.
Provide at least 15.24 cm (6 inches) of clearance at the front and back of the workstation. (Workstation models vary.)
Be sure that the ambient air temperature falls within the environmental specifications listed in this document.
NOTE: The ambient upper limit of 35°C (95°F) is only good up to 1524 m (5000 ft) elevation. There is a
1°C (33.8°F) per 304.8 m (1000 ft) derating above 1524 m (5000 ft). So, at 3,048 m (10,000 ft), the upper ambient air temperature limit is 30°C (86°F).
For cabinet installation, be sure that adequate cabinet ventilation and the ambient temperature within the cabinet does not exceed specified limits.
Never restrict the incoming or outgoing airflow of the workstation by blocking any vents or air intakes, as shown in the following figure.
Ensuring proper ventilation 19

Power management and performance features

ERP compliance mode

This computer provides ERP compliance mode capability.
When enabled, the computer shuts down to the lowest possible power state. The computer must then be turned on with the power button. One of the effects is that "wake on LAN" is disabled.
When disabled, the computer powers down conventionally.
1. Press f10 during startup.
2. Using the arrow keys, select the Power > Hardware Power Management > S5 Maximum
Power Savings, then select Enable.
3. Press f10 to accept the change.

4. Select File > Save Change and Exit, and then press enter to accept the change.
5. If using Windows 8 or Windows 8.1, boot to Windows and search in the Start Menu for the
setting Change what the power buttons do. Uncheck Turn on fast startup (recommended). If the checkbox is not available, select Change settings that are currently unavailable at the top of the window.
1. Press f10 during startup.
