Chapter 1: Introduction
1-11
Press the power button again to "wake-up" the whole system. During the SoftOff
state, the ATX power supply provides power to the required circuitry and keep the
system "alive." In case the system malfunctions and you want to turn off the power,
just press and hold the power button for 4 seconds. The power will turn off and no
power will be provided to the motherboard.
Wake Ring-On (WOR)
Wake-up events can be triggered by a device such as the external modem ringing
when the system is in the SoftOff state. Note that external modem ring-on can only
be used with an ATX 2.01 (or above) compliant power supply.
Wake-On-LAN (WOL)
Wake-On-LAN is defi ned as the ability of a management application to remotely
power up a computer that is powered off. Remote PC setup, up-dates and asset
tracking can occur after hours and on weekends so that daily LAN traffi c is kept to
a minimum and users are not interrupted. The motherboard has a 3-pin header
(WOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has
WOL capability. Note that Wake-On-LAN can only be used with an ATX 2.01 (or
above) compliant power supply.
1-5 ACPI Features
ACPI stands for Advanced Confi guration and Power Interface. The ACPI specifi ca-
tion defi nes a fl exible and abstract hardware interface that integrates power man-
agement features with other components of a PC system, including its hardware,
operating system and application software. This enables the system to automati-
cally turn on and off peripherals such as CD-ROMs, network cards, hard disk drives
and printers. This also includes other devices connected to the PC such as VCRs,
TVs, telephones and stereos.
In addition to enabling operating system-directed power management, ACPI
provides a generic system event mechanism for Plug and Play and an operating
system-independent interface for confi guration control. ACPI leverages the Plug
and Play BIOS data structures while providing a processor architecture-independent
implementation that is compatible with both Windows and Linux Operating Systems.
1-6 Power Supply
As with all computer products, a stable power source is necessary for proper and
reliable operation. It is even more important for processors that have high CPU
clock rates of 1 GHz and faster.
