About the Soft Touch Power Button
In an ATX based system, the new soft touch power
button replaces the main power switch that turns your system
on and off. From an OFF state, you can switch the system
ON by simply pressing the power button. From an ON state,
the system can be turned OFF by pressing and holding the
power button for four (4) seconds OR shut down instantly. The
functions of the power button can also be altered in the Power
Management section of the CMOS setup.
C
Universal Serial Bus (USB) Connector
The Mainboard provides four 4-pin Universal Serial
Bus (USB) connectors. USB is a new interface standard for
adding external Plug-and-Play (PnP) devices to the computer
system. Peripherals that support USB PnP capabilities can
operate at up to a 12Mb/sec data transfer rate. Eventually,
all external devices connected to your computer will be
standardized to USB.
E
Infra-Red (IR) Connector
The Mainboard provides a 5-pin header interface, IR
for connection to a Hewlett Packard HSDSL-1000 compatible
infrared (IrDA) transmitter/receiver. Connect IR to the front
panel I/O IrDA connector provided with your system. Once the
module is connected to the front panel I/O IrDA connector,
Serial port 2 can be re-directed to the IrDA module. When
configured for IrDA, the user can transfer files to or from
portable devices such as laptops, PDA’s and printers using
application software such as LapLink. The IrDA specification
provides for data transfers at 115 kbps from a distance of
1-meter. Support for Consumer infrared (ASK-IR) is also
included. Please refer to your IR equipment for more detailed
information.
