X8DTU-LN4F+ Motherboard User’s Manual
2. To provide adequate power to the add-on cards installed on the mother-
board, please connect the UIOP PWR connector to the power supply.
It is strongly recommended that you use a high quality power supply that meets ATX
power supply Speci cation 2.02 or above. It must also be SSI compliant. (For more
information, please refer to the web site at http://www.ssiforum.org/). Additionally, in
areas where noisy power transmission is present, you may choose to install a line
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.
2-7 Super I/O
The Super I/O supports two high-speed, 16550 compatible serial communication
ports (UARTs). Each UART includes a 16-byte send/receive FIFO, a programmable
baud rate generator, complete modem control capability and a processor interrupt
system. Both UARTs provide legacy speed with baud rate of up to 115.2 Kbps
as well as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which
support higher speed modems.
The Super I/O provides functions that comply with ACPI (Advanced Con guration
and Power Interface), which includes support of legacy and ACPI power manage-
ment through an SMI or SCI function pin. It also features auto power management
to reduce power consumption.
2-8 Overview of the Nuvoton WPCM450 Controller
The Nuvoton WPCM450 Controller is a Baseboard Management Controller (BMC)
that supports the 2D/VGA-compatible Graphics Core with the PCI interface,
Virtual Media, and Keyboard/Video/Mouse Redirection (KVMR) modules. With
blade-oriented Super I/O capability built-in, the WPCM450 Controller is ideal for
legacy-reduced server platforms.
The WPCM450 interfaces with the host system via a PCI interface to communicate
with the Graphics core. It supports USB 2.0 and 1.1 for remote keyboard/mouse/
virtual media emulation. It also provides LPC interface to control Super IO func-
tions. The WPCM450 is connected to the network via an external Ethernet PHY
module.
The WPCM450 communicates with onboard components via six SMBus interfaces,
fan control, and Platform Environment Control Interface (PECI) buses.
