information, please refer to the website 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.
1-7 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 Configuration
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.
1-8 Advanced Power Management
The following advanced power management features are supported by this moth-
erboard:
Intel
®
Intelligent Power Node Manager (NM) (Available
when the NMView utility is installed in the system)
The Intel
®
Intelligent Power Node Manager (IPNM) provides your system with
real-time thermal control and power management for maximum energy efficiency.
Although IPNM Specification Version 1.5/2.0 is supported by the BMC (Baseboard
Management Controller), your system must also have IPNM-compatible Manage-
ability Engine (ME) firmware installed to use this feature.
Note
: Support for IPNM Specification Version 1.5 or Vision 2.0 depends
on the power supply used in the system.
Manageability Engine (ME)
The Manageability Engine, which is an ARC controller embedded in the PCH,
provides Server Platform Services (SPS) to your system. The services provided by
SPS are different from those provided by the ME on client platforms.
