System Architecture Distinctions and Default Settings

The SPARC architecture of a workstation determines which Power Management features are available. The default behavior in Power Management functions varies on systems, as described in Table 1-1.

To determine your system's architecture, use the uname -m command.

If you have Sun Microsystems^TM hardware that is not described by this manual, refer to the Sun Hardware Platform Guide for this Solaris release. It may contain additional information about how Power Management software functions on your system.
