Chapter 1: Introduction
1-25
1-6 Super I/O
The Super I/O provides 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 sup-
port higher speed modems.
The Super I/O provides functions that comply with ACPI (Advanced Configuration
and Power Interface), which includes support of legacy and ACPI power manage-
ment through a SMI or SCI function pin. It also features auto power management
to reduce power consumption.
1-7 Overview of the Nuvoton BMC Controller (X7SPA-
HF/X7SPE-HF/X7SPE-HF-D525/X7SPA-HF-D525 only)
The Nuvoton
SM
Baseboard Management Controller (BMC), supports the 2D/VGA-
compatible Graphics Core with the PCI interface, Virtual Media, and Keyboard/
Video/Mouse (KVM) Redirection modules.
The Nuvoton BMC interfaces with the host system via a PCI interface to commu-
nicate 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 I/O
functions and is connected to the network via an external Ethernet PHY module. It
also communicates with onboard components via six SMBus interfaces, fan control,
Platform Environment Control Interface (PECI) buses, and General Purpose I/O
(T-SGPIO) ports.
The Nuvoton WPCM450 (Manufacturer P/N WPCM450RA0BX) has all the features
as described above plus IPMI 2.0 support. This particular chip is installed in the
X7SPA-HF/X7SPE-HF/X7SPE-HF-D525/X7SPA-HF-D525 motherboard model.
Note:
For the X7SPA-HF/X7SPE-HF/X7SPE-HF-D525/X7SPA-HF-D525,
IPMI is supported (shared) using LAN1. Please refer to the Embedded
IPMI User's Guide posted on our website at http://www.supermicro.com/
