Acpi Features; Power Supply - Supermicro M11SDV-4C-LN4F User Manual

1.5 ACPI Features

ACPI stands for Advanced Configuration and Power Interface. The ACPI specification defines
a flexible and abstract hardware interface that provides a standard way to integrate power
management features throughout a computer system, including its hardware, operating
system and application software. This enables the system to automatically turn on and off
peripherals such as CD-ROMs, network cards, hard disk drives and printers.
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.

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.
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 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.
Note: The M11SDV-4C/4CT/8C/8CT/8C+-LN4F motherboard supports either 12V DC in
power input or ATX power input. The 12V DC IN power input requires an 8-pin 12V DC
IN connection to the JPV1 header. ATX power input requires an 8-pin 12V connections
to JPV1 header and PJ1 a 4-pin power connector of an ATX power supply by power
cable (24-pin ATX to 4-pin power cable for PJ1, Supermicro P/N: CBL-PWEX-1063).
PJ1 allows motherboard control of the 5VStby, power on, power good, and ground
signals from the ATX power supply.
