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 defined as the ability of a management application to remotely
power up a computer that is powered off. Remote PC setup, updates and asset
tracking can occur after hours and on weekends so that daily LAN traffic is kept to a
minimum and users are not interrupted. The motherboards have 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.
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 VIG705P can only accommodate ATX 24-pin power supplies. Although 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 and includes
the addi12V, 8-pin power connector – an even higher wattage power supply
is recommended for high-load configurations. Also your power supply must supply
1.5A for the Ethernet ports.
NOTE!
An additional 12v power 8-pin power connector (PW2) is required to support Intel
Xeon CPUs. Failure to provide this extra power will result in instability of the CPUs
after only a few minutes of operation.
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.
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.
Super I/O
The disk drive adapter functions of the Super I/O chip include a floppy 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 generator,
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 floppy disk drives. The Super I/O supports 360 K, 720 K, 1.2 M, 1.44
M or 2.88 M disk drives and data transfer rates of 250 Kb/s, 500 Kb/s or 1 Mb/s. It
