A1SRM-LN7F/LN5F Series Motherboard User’s Manual
1-5 ACPI Features
ACPI stands for Advanced Conguration and Power Interface. The ACPI specica-
tion denes a exible and abstract hardware interface that provides a standard
way to integrate power management features throughout a PC 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 conguration control. ACPI leverages the Plug and
Play BIOS data structures, while providing a processor architecture-independent
implementation that is compatible with Windows 7, Windows 8, and Windows 2008
operating Systems. A1SRM Series motherboard supports S0 and S5 only.
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.
Note 1: The A1SRM-LN7F/LN5F Series motherboard alternatively sup-
ports a 4-pin 12V DC input power supply for embedded applications. The
12V DC input is recommended up to 14A by design, therefore it provides
up to 168W power input to the motherboard. Please keep onboard power
use within the power limits specied above. Over-current DC power use
may cause damage to the motherboard!
Note 2: Do not use the 4-pin DC power at JPW2 when the 24-pin ATX
power at JPW1 is connected to the power supply. Do not plug in both
JPW2 and JPW1 at the same time.
It is strongly recommended that you use a high quality power supply that meets ATX
power supply Specication 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
lter 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.
