I/O Shield Connector
The board is equipped with an I/O back panel. Please use the appropriate I/O shield
(figure 3).
Power-On/Off (Remote)
The board has a single 20-pin and 4-pin connector for ATX or ATX12V power supplies.
For ATX or ATX12V power supplies that support the Remote On/Off feature, this
should be connected to the systems front panel for system Power On/Off button.
The systems power On/Off button should be a momentary button that is normally open.
The board has been designed with Soft Off" functions. You can turn Off the system
from one of two sources: The first is the front panel Power On/Off button, and the
other is the "Soft Off" function (coming from the BOARDs onboard circuit control-
ler) that can be controlled by the operating system such as Windows
®
95/98 and
Windows
®
2000 to Shutdown the system.
Note: For maintaining the DDR SDRAM power during STR (ACPI S3) function, it is
strongly recommend to use ATX or ATX12V power supplies that have a +5VSB
current of (>=) 1A (1000mA). Please check the 5VSBs specification that has
been printed on the ATX or ATX12V power supplys outer case.
Note: The board requires a minimum of 250 Watt ATX or ATX 12V power supply to
operate. Your system configuration (amount of memory, add-in cards, peripherals,
etc.) may exceed the minimum power requirement but to ensure that adequate
power is provided, use a 300 Watt (or greater) ATX or ATX 12V power supply.
