Chapter 8 Power Management on Sun Hardware

The U.S. Environmental Protection Agency has launched the Energy Star Computers program to encourage the introduction and use of energy-efficient computer systems and to reduce air pollution associated with energy generation.

In response to this policy, Sun is providing Power Management(TM) software. In order to reduce the amount of power your Sun workstation uses, your Sun workstation is now capable of entering a lower power state when the display is inactive for a period of time.

This section supplements Using Power Management in the Solaris 7 User Collection.

Supported Platforms

Power Management software supports the sun4m and sun4u platform groups. Software features and defaults may vary between the two platform groups. Refer to Using Power Management in the Solaris 7 User AnswerBook set for more information when you identify the platform group that applies to your system.

Note -

Power Management does not support the sun4c and sun4d platform groups

SPARCstation 4 Issues

This section describes a workaround to a limitation of the SPARCstation 4 when used with Power Management.

The AC accessory outlet on the SPARCstation 4 system unit is an unswitched outlet. The AC power switch does not control power flowing through the accessory outlet. If you connect a monitor to the accessory outlet, you cannot turn it off using the system unit power switch. Similarly, if you use Power Management software, the software cannot turn off the monitor automatically. To conserve energy, consider using an Energy Star compliant monitor. Sun offers a variety of Energy Star compliant monitors in its standard SPARCstation 4 system configurations. This information does not apply to SPARCserver 4 configurations. The SPARCserver 4 includes a switched accessory outlet.
