X7DWN+ User's Manual
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. In addition, an onboard LAN controller can also support WOL
without any connection to the WOL header. The 3-pin WOL header is to be used
with a LAN add-on card only.
Note : Wake-On-LAN requires 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 X7DWN+ can accommodate 24-pin ATX power supplies. Although most
power supplies generally meet the specifi cations required by the CPU, some are
inadequate. In addition, the 12V 4-pin and the 12V 8-pin power connections are
also required to ensure adequate power supply to the system. Also your power
supply must supply 1.5A for the Ethernet ports.
Note: The + 12V 8-pin CPU Power Connector (JPW3) is also required to support
Intel 64-bit CPUs. Failure to provide this extra power will result in CPU PWR Failure.
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 Specifi cation 2.02 or above. It must also be SSI compliant
(For more information, please refer to the web site at http://www.ssiforum.org/).
Additionally, in areas where noisy power transmission is present, you may choose
to install a line fi lter 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.
1-7 Super I/O
The disk drive adapter functions of the Super I/O chip include a fl oppy disk drive
controller that is compatible with industry standard 82077/765, a data separator,
write pre-compensation circuitry, decode logic, data rate selection, a clock genera-
tor, drive interface control logic and interrupt and DMA logic. The wide range of
functions integrated onto the Super I/O greatly reduces the number of components
required for interfacing with fl oppy disk drives. The Super I/O supports 360 K, 720
