Power and Signal Distribution

7.3.2 Wake Up Events

The system can be activated with a power “wake-up” of the system due to the occurrence of a magic packet, serial port ring, or PCI power management event (PME). These events can be individually enabled through the Setup utility to wake up the system from a sleep (low power) state.

✎Wake-up functionality requires that certain circuits receive auxiliary power while the system is turned off. The system unit must be plugged into a live AC outlet for wake up events to function. Using an AC power strip to control system unit power will disable wake-up event functionality.

The wake up sequence for each event occurs as follows:

Wake-On-LAN

The network interface controller (NIC) can be configured for detection of a “Magic Packet” and wake the system up from sleep mode through the assertion of the PME- signal on the PCI bus. Refer to Chapter 5, “Network Support” for more information.

Modem Ring

A ring condition on a serial port can be detected by the power control logic and, if so configured, cause the power control logic to wake up the system.

Power Management Event

A power management event that asserts the PME- signal on the PCI bus can be enabled to cause the power control logic to wake up the system. Note that the PCI card must be PCI ver. 2.2 (or later) compliant to support this function.

7.4Power Management

These systems include power management functions that conserve energy by turning off or inhibiting power to various subsystems and components. These functions are provided by a combination of hardware, firmware (BIOS) and software. These systems provide the following power management support:

■ACPI v2.0 compliant (ACPI modes C1, S1, and S3-S5)

■APM 1.2 compliant

■U.S. EPA Energy Star 3.0 and 4.0 compliant

Table 7-6 shows the comparison in power states.
