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 on 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 SoftOff state. Note that the 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 remotely
power up a computer that is powered off. Remote PC setup, updates 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. Note that Wake-On-
LAN can only be used with an ATX 2.01 (or above) compliant power supply.
1-6 Power Supply Requirements
As with all computer products, a stable power source is necessary for proper and
reliable operation. This is even more important for the 400 MHz and higher clock
rates of Xeon processors.
The SUPER S2DG2/S2DGU/S2DGE/S2DGR accommodates ATX power sup-
plies. Although most power supplies generally meet the specifications required
by the CPU, some are inadequate.
It is highly recommended that you use a high quality power supply that meets
ATX power supply Specification 2.01. Additionally, in areas where noisy power
transmission is present, you may choose to install a line filter to shield the
