X11SAA/A2SAV/-2C/-L User's Manual

1.2 Processor Overview

Built upon the functionality and capability of the Intel® Atom® processor E3900 series

and Intel® Pentium® processor N4200 platform, the X11SAA/A2SAV/-2C/-L motherboard

offers maximum I/O expandability, energy efciency, and data reliability in a 14-nm process

architecture, and is optimized for embedded storage solutions.

The X11SAA/A2SAV/-2C/-L supports the following features:

• Intel Turbo Boost Technology

• Intel Trusted Execution Engine (Intel TXE) 3.0

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

• GbE LAN ports

• COM ports (two RS32 and one RS-485; one RS-232 is on RJ45 connector)

• M.2 slot with 2242/2280 M-Key

• Display port, HDMI, VGA or eDP connections

1.3 Special Features

This section describes the health monitoring features of the X11SAA/A2SAV/-2C/-L

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

system health monitoring.

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.

17

Chapter 1: Introduction

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 8/R2 and Windows 2012/R2 operating systems.

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 (Nuvoton NCT5523D chip) includes a data separator, write pre-compensation

circuitry, decode logic, data rate selection, a clock generator, drive interface control logic and

interrupt and DMA logic. The wide range of functions integrated onto the Super I/O greatly

reduces the number of components required for interfacing with oppy disk drives.

The Super I/O provides two high-speed, 16550 compatible serial communication ports

(UARTs), one of which supports serial infrared communication. Each UART includes a 16-byte

send/receive FIFO, a programmable baud rate generator, complete modem control capability

and a processor interrupt system. Both 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.

The Super I/O provides functions that comply with ACPI (Advanced Conguration and Power

Interface), which includes support of legacy and ACPI power management through a SMI

or SCI function pin. It also features auto power management to reduce power consumption.

The IRQs, DMAs and I/O space resources of the Super I/O can be exibly adjusted to meet

ISA PnP requirements, which support ACPI and APM (Advanced Power Management).

2.1 Static-Sensitive Devices

Electrostatic Discharge (ESD) can damage electronic com ponents. To prevent damage to your

motherboard, it is important to handle it very carefully. The following measures are generally

sufcient to protect your equipment from ESD.

Precautions

• Use a grounded wrist strap designed to prevent static discharge.

• Touch a grounded metal object before removing the board from the antistatic bag.

• Handle the board by its edges only; do not touch its components, peripheral chips, memory

modules or gold contacts.

• When handling chips or modules, avoid touching their pins.

• Put the motherboard and peripherals back into their antistatic bags when not in use.

• For grounding purposes, make sure that your chassis provides excellent conductivity be-

tween the power supply, the case, the mounting fasteners and the motherboard.

• Use only the correct type of CMOS onboard battery as specied by the manufacturer. Do

not install the CMOS battery upside down, which may result in a possible explosion.

Unpacking

The motherboard is shipped in antistatic packaging to avoid static damage. When unpacking

the motherboard, make sure that the person handling it is static protected.

2.2 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 the motherboard and the chassis match.

Although a chassis may have both plastic and metal mounting fasteners, 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.

Location of Mounting Holes

Note: 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.

Installing the Motherboard

1. Install the I/O shield into the back of the chassis.

2. Locate the mounting holes on the motherboard. See the previous page for the location.

3. Locate the matching mounting holes on the chassis. Align the mounting holes on the

motherboard against the mounting holes on the chassis.

4. Install standoffs in the chassis as needed.

5. Install the motherboard into the chassis carefully to avoid damaging other motherboard

components.

6. Using the Phillips screwdriver, insert a Phillips head #6 screw into a mounting hole on

the motherboard and its matching mounting hole on the chassis.

7. Repeat Step 5 to insert #6 screws into all mounting holes.

8. Make sure that the motherboard is securely placed in the chassis.

Note: Images displayed are for illustration only. Your chassis or components might

look different from those shown in this manual.
