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 Specification 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 filter 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 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 PCI interface, Virtual Media, and Keyboard/Video/Mouse Redirection (KVMR) modules.

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 Nuvoton WPCM450 Controller also 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 and an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which support higher speed modems.

The WPCM450 communicates with onboard components via six SMBus interfaces, fan control, and Platform Environment Control Interface (PECI) buses.

Note: For more information on IPMI configuration, please refer to the Embedded IPMI User's Guide posted on our website @ http://www.super- micro.com/support/manuals/.

2-8 Super I/O

The Super I/O chip (Winbond W83527HG) provides functions that comply with ACPI (Advanced Configuration and Power Interface), which includes support of legacy and ACPI power management through an SMI or SCI function pin.
