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 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. Wake-On-LAN must be enabled in BIOS. Note that Wake-On-LAN
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 X6DHR-3G2/X6DHR-EG2 accommodates ATX power 20-pin supplies.
Although most power supplies generally meet the specifi cations required by the
system, some are inadequate. You should use one that will supply at least 420W
of power.
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 (info
at http://www.ssiforum.org/). Additionally, in areas where noisy power transmis-
sion 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. (*Please refer to the next page for additional
information.)
NOTES: 1. A 12V 8-pin power (JID1) is required to support Intel Xeon CPUs.
In addition, a 12V 4-pin PWR connection is also required. See Section 2-5 for
details on connecting the power supply cables.
2. Be sure to use the correct type of onboard CMOS battery as specifi ed
by the Manufacturer. Do not install the CMOS battery up-side down to avoid
possible explosion.
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-
