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 de fi 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 traf
fi 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 X7DBN can only accommodate 24-pin ATX power supplies. Although most
power supplies generally meet the speci
fi cations required by the CPU, some are
inadequate. In addition, the 12V 4-pin power supply - is 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 Aux. Power Connector 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 Speci
fi cation 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
fi lter to shield the computer from noise.
It is recommended that you also install a power surge protector to help avoid prob-
lems caused by power surges.
