Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start
blinking to indicate that the CPU is in suspend mode. When the user presses
any key, the CPU will wake-up and the LED will automatically stop blinking
and remain on.
Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a
system suspend button to make the system enter a SoftOff state.
monitor will be suspended and the hard drive will spin down. Pressing the
power button again will cause the whole system to wake-up.
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 press and hold the power button for 4 seconds.
This option can be set in the Power section of the BIOS Setup routine.
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 2.02 (or above) compliant power
supply.

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 X6DAL-B2/X6DAL-TB2 accommodates ATX power supplies.
most power supplies generally meet the specifications required by the CPU,
some are inadequate. You should use one that will supply at least 420 W 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.
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
