1-3 Special Features

Recovery from AC Power Loss

Basic I/O System (BIOS) provides a setting for you to determine how the system will

respond when AC power is lost and then restored to the system. You can choose

for the system to remain powered off, (in which case you must press the power

switch to turn it back on), or for it to automatically return to a power-on state. See

the Advanced BIOS Setup section to change this setting. The default setting is

Last State.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the board. All have

an onboard System Hardware Monitoring chip that supports PC health monitoring.

An onboard voltage monitor will scan these onboard voltages continuously: VCCP,

VDIMM, 12V, 5VCC, 3.3VCC, VBAT, 5V, Dual, and 3.3V AUX. Once a voltage be-

comes unstable, a warning is given, or an error message is sent to the screen. The

user can adjust the voltage thresholds to dene the sensitivity of the voltage monitor.

Environmental Temperature Control

This motherboard comes with a built-in passive heatsink. Please follow the instruc-

tions given in your system design guide or your system user manual to provide

proper/adequate airow to your system. The onboard BaseBoard Management

Controller (BMC) monitors CPU, memory and motherboard environment tempera-

tures for fan control and PC health management.

Note: To avoid possible system overheating, please be sure to provide

adequate airow to your system.

System Resource Alert

This feature is available when the system is used with SuperDoctor® 5 in the

Windows OS environment or used with SuperDoctor II in Linux. SuperDoctor

is used to notify the user of certain system events. For example, you can also

congure SuperDoctor to provide you with warnings when the system temperature,

CPU temperatures, voltages and fan speeds go beyond predened thresholds.

A1SAi & A1SRi 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. A1SAi/A1SRi Series motherboards support 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 A1SAi and A1SRi Series motherboard alternatively supports

a 4-pin 12V DC input power supply for embedded applications. The 12V

DC input is limited to 12A by design. It provides up to 144W 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 J1 when the 24-pin ATX Power

at JPW1 is connected to the power supply. Do not plug in both J1 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 website 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.

Caution: 1) To avoid damaging the motherboard and its components, please do

not use a force greater than 8 lb/inch on each mounting screw during motherboard

installation. 2) Some components are very close to the mounting holes. Please take

precautionary measures to avoid damaging these components when installing the

motherboard to the chassis.

2-4 Motherboard Installation

All motherboards have standard mounting holes to t different types of chassis.

Make sure that the locations of all the mounting holes for both motherboard and

chassis match. Although a chassis may have both plastic and metal mounting fas-

teners, metal ones are highly recommended because they ground the motherboard

to the chassis. Make sure that the metal standoffs click in or are screwed in tightly.

Then use a screwdriver to secure the motherboard onto the motherboard tray.
