Power Supply; Advanced Power Management - Supermicro X11SAT User Manual

In addition to enabling operating system-directed power management, ACPI also provides a
generic system event mechanism for Plug and Play and an operating system-independent
interface for configuration control. ACPI leverages the Plug and Play BIOS data structures
while providing a processor architecture-independent implementation that is compatible with
Windows 8/R2, and Windows 2012/R2 operating systems.

1.6 Power Supply

As with all computer products, a stable power source is necessary for proper and reliable
operation. It is even more important for processors that have high CPU clock rates. 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 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 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 management through a SMI
or SCI function pin. It also features auto power management to reduce power consumption.

1.8 Advanced Power Management

The following new advanced power management features are supported by the motherboard.
Intel Intelligent Power Node Manager (IPNM)
®
Available when the Supermicro Power Manager (SPM) is installed, Intel's Intelligent Power
Node Manager (IPNM) provides your system with real-time thermal control and power
management for maximum energy efficiency. Although IPNM Specification Version 2.0/3.0
is supported by the BMC (Baseboard Management Controller), your system must also have
IPNM-compatible Management Engine (ME) firmware installed to use this feature.
Note: Support for IPNM 2.0/3.0 support is dependent on the power supply used in
the system.
