Introduction
Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a
system suspend button. When the user depresses the power button, the
system will enter a SoftOff state. The monitor will be suspended and the
hard drive will spin down. Depressing the power button again will cause
the whole system to wake-up. During the SoftOff state, the ATX power
supply provides power to keep the required circuitry in the system alive. In
case the system malfunctions and you want to turn off the power, just
depress and hold the power button for 4 seconds. The power will turn off
and no power will be provided to the motherboard.
External Modem Ring-On
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 defined as the ability of a management application to re-
motely 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 traffic is kept to a minimum and users are not interrupted. The
motherboards have a 3-pin header (WOL) to connect to the 3-pin header on
a Network Interface Card (NIC) that has WOL capability. Wake-On-LAN
must be enabled in BIOS. Note that Wake-On-Lan can only be used with an
ATX 2.01 (or above) compliant power supply.
1-6 Power Supply
As with all computer products, a stable power source is necessary for
proper and reliable operation. The SUPER S2QR6/S2QE6 accommodates
ATX power supplies. Although most power supplies generally meet the
specifications required by the CPU, some are inadequate.
From a system board point of view, the major power-consuming compo-
nents are the processors and certain add-on cards. The system integrator
should select an appropriate power supply after considering the power
consumption and requirements of the major power-consuming components
in the system. Generally speaking, one (1) Pentium III Xeon Cascades 2.8V
