Super I/O; Overview Of The Winbond Wpcm450 Controller - Supermicro X8DTN+-F-LR User Manual

X8DTN+-F/X8DTN+-F-LR User's Manual
Warning: To prevent damage to the power supply or motherboard, please
use a power supply that contains a 24-pin and two 8-pin power connec-
tors. Be sure to connect these connectors to the 24-pin (JPW1) and the
two 8-pin (JPW2,JPW3) power connectors on the motherboard. Failure in
doing so will void the manufacturer warranty on your power supply and
motherboard.

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 Confi 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.

Overview of the Winbond WPCM450 Controller

The Winbond 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.
