Preface

About This Manual

This manual is written for system integrators, IT technicians and knowledgeable end users.

It provides information for the installation and use of the A2SAP-H/-E/-L motherboard.

About This Motherboard

The A2SAP-H/-E/-L motherboard provides powerful graphics and increased media processing

performance with multi-frame technology. Paired with the Intel® Atom SoC (System-on-a-

Chip) processor, the A2SAP-H/-E/-L delivers more computing power for faster memory speeds

and bandwidth while maintaining energy efciency. Utilizing Intel® TCC (Time Coordinated

Computing) Technology, the A2SAP-H/-E/-L resolves latency issues in applications and

improves determinism across connected devices. The motherboard features advanced

technologies such as Intel® Virtualization to improve security and reliabity of systems, and

Thermal Monitoring to reduce power consumption. It also comes with more I/O ports and

high-speed connectivity.

Please note that this motherboard is intended to be installed and serviced by professional

technicians only. For processor/memory updates, please refer to our website at http://www.

supermicro.com/products/.

Conventions Used in the Manual

Special attention should be given to the following symbols for proper installation and to prevent

damage done to the components or injury to yourself:

Warning! Indicates high voltage may be encountered when performing a procedure.

Warning! Indicates important information given to prevent equipment/property damage

or personal injury.

Important: Important information given to ensure proper system installation or to

relay safety precautions.

Note: Additional Information given to differentiate various models or provides infor-

mation for correct system setup.

1.3 Special Features

This section describes the health monitoring features of the A2SAP-H/-E/-L motherboard.

The motherboard has an onboard System Hardware Monitor chip that supports system health

monitoring.

Super A2SAP-H/-E/-L User's Manual

Recovery from AC Power Loss

The Basic I/O System (BIOS) provides a setting that determines 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 the power-on state. See the Advanced BIOS Setup section

for this setting. The default setting is Last State.

Note: Before setting the Recovery from AC Power Loss function in the BIOS, please

adjust force power on jumper JLCDPWR1 to pins 4-6 to disable the force power-on

function.

1.4 ACPI Features

ACPI stands for Advanced Conguration and Power Interface. The ACPI specication denes

a exible 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 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® 10.

1.5 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 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.
