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 A2SAN-H/-E/-L and X11SAN

motherboard.

About This Motherboard

The A2SAN-H/-E/-L and X11SAN 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 A2SAN-H/-E/-L and X11SAN delivers more computing

power for faster memory speeds and bandwidth while maintaining energy efciency. Utilizing

Intel® TCC (Time Coordinated Computing) Technology, the A2SAN-H/-E/-L and X11SAN

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.

Chapter 1: Introduction

1.2 Processor Overview

Built upon the functionality and capability of the Intel® Atom SoC series processor, the

A2SAN-H/-E/-L and X11SAN motherboard offers maximum I/O expandability, energy

efficiency, and data reliability in a 14-nm process architecture, and is optimized for

embedded storage solutions, networking applications, or cloud-computing platforms. The

A2SAN-H/-E/-L and X11SAN drastically increases system performance for a multitude of

server applications.

The A2SAN-H/-E/-L and X11SAN supports the following features:

• Intel Virtualization Technology for Directed I/O (Intel VT-d)

• Enhanced Intel SpeedStep® Technology

• Video Connectors: VGA, HDMI, and LVDS

• USB3.1 Gen 2 Type-C (Only supported on X11SAN and A2SAN-H)

• Adaptive Thermal Management/Monitoring

• Mini-PCI-E slot with PCIe Gen2 x1 with transfer rates of up to 5Gb/s

• Gen3 SATA ports with transfer rates of up to 6Gb/s

• System Management Bus (SMBus) Specication, Version 2.0

• M.2 slot with B-key 2280/2242/3042 module is supported by an extender bracket

• TPM2.0 (Trusted Platform Module) onboard with Disable/Enable jumper (not supported on

A2SAN-L)

• Integrated Sensor Hub (ISH)

• Intel® Identity Protection Technology

1.3 Special Features

This section describes the health monitoring features of the A2SAN-H/-E/-L and X11SAN

motherboard. The motherboard has an onboard System Hardware Monitor chip that supports

system health monitoring.

Super A2SAN-H/-E/-L and X11SAN 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 JPF1 to pins 2-3 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.

1.6 Super I/O

The Super I/O (NCT6106D chip) provides four high-speed, 16550 compatible serial

communication ports (UARTs), one of which supports serial infrared communication. Each

UART includes a 128 byte send/receive FIFO, a programmable baud rate generator, complete

modem control capability and a processor interrupt system. 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.
