Introduction
External Modem 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.
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.
The SUPER X6DAL-G/X6DAL-TG accommodates ATX power supplies. Al-
though most power supplies generally meet the specifications required by
the CPU, some are inadequate. You should use one that will supply at least
400W of power. In addition, a +12V, 8-pin CPU power supply and a +12V,
4-pin Aux. power supply are also required for high-load configurations.
Also your power supply must supply 1.5A for the Ethernet ports.
NOTE: In addition to the 24-pin main power, a 12V 8-pin power con-
nector (PW2) is required to support Intel Xeon CPUs, and a 12V 4-
pin power connector (Aux. PWR) is also required for system power
consumption. Failure to provide this extra power will result in
instability of the CPU after only a few minutes of operation. See
Section 2-5 for details on connecting the power supply.
It is strongly recommended that you use a high quality power supply that
meets ATX power supply Specification 2.02 or above. It must also be SSI
compliant (info at http://www.ssiforum.org/). Additionally, in areas where
noisy power transmission is present, you may choose to install a line filter
to shield the computer from noise. It is recommended that you also install a
power surge protector to help avoid problems caused by power surges.
