Power-On/Off (Remote)
The board has a single 20-pin connector for ATX power supplies (Figure 4). For
ATX power supplies that support the Remote On/Off feature, this should be
connected to the mainboard front panel PW_ON connector for the computer
power On/Off button.
The board has been designed with Soft Off" function. You can turn off the system
two ways: pressing the front panel power On/Off button, using the "Soft Off"
function (incorporated in the mainboards onboard circuit controller) that can be
controlled by an operating system such as Windows
®
ME/2000/98/95.
Note: For maintaining the RDRAM power during STR (ACPI S3) function, it is strongly
recommend to use ATX power supplies that have a +5VSB current of (>=) 1A
(1000mA). Please check the 5VSBs specification that has been printed on the
ATX power supplys outer case.
Note: The board requires a minimum of 250 Watt ATX 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 power supply.
I/O Shield Connector
The board is equipped with an I/O back panel (Figure 3). Ensure that your com-
puter case has the appropriate I/O cutout.
