Safety Precautions
Warning!
Always completely disconnect the power cord from your
chassis whenever you work with the hardware. Do not make
connections while the power is on. Sensitive electronic
components can be damaged by sudden power surges. Only
experienced electronic personnel should open the PC chassis.
Caution!
Always ground yourself to remove any static charge before
touching the CPU card. Modern electronic devices are very
sensitive to static electric charges. As a safety precaution, use a
grounding wrist strap at all times. Place all electronic
components in a static-dissipative surface or static-shielded bag
when they are not in the chassis.

Chapter 2 Installations
2.1. Installation Precautions
Cautions
The procedures in this chapter assume familiarity with the general
terminology associated with single board computers and with the safety practices
and regulatory compliance required for using and modifying electronic
equipment.
Disconnect the computer from its power source and from any
telecommunications links, networks, or modems before performing any of the
procedures described in this chapter. Failure to disconnect power,
telecommunications links, networks, or modems before you open the computer or
perform any procedures can result in personal injury or equipment damage.
Some circuitry on the board can continue to operate even though the front panel
power button is off.
Follow these guidelines before you begin installing the IA71 Motherboard:
Always follow the steps in each procedure in the correct order.
Set up a log to record information about your computer, such as model,
serial numbers, installed options, and configuration information.
Electrostatic discharge (ESD) can damage components. Perform the
procedures described in this chapter only at an ESD workstation using an
antistatic wrist strap and a conductive foam pad. If such a station is not
available, you can provide some ESD protection by wearing an antistatic wrist
strap and attaching it to a metal part of the computer chassis.
When you install and test the IA71 Motherboard, observe all warnings and
cautions in the installation instructions.
To avoid injury, be careful of:
Sharp pins on connectors or headers
Sharp pins on printed circuit assemblies
Rough edges and sharp corners on the chassis
Hot components (like processors, voltage regulators, and heat sinks)
Damage to wires that could cause a short circuit
Observe all warnings and cautions that instruct you to refer computer
servicing to qualified technical personnel.
Do not overload the power supply output. To avoid overloading the power
supply, make sure that the calculated total current loads of all the modules within
IA71 Motherboard User Manual V1.0

the computer is less than the output current rating of each of the power supplies
output circuits.
2.2. Installing and Removing Memory Modules
IA71 motherboard supports one 200-pin SODIMM slot. The socket supports
up to 2GB DDR2 400/533 SDRAM. Press downwards on SODIMM until the
retaining clips at both ends fully snap back in place and the SODIMM is properly
seated. To install the DDR2 modules, locate the memory socket on the board and
perform the
Caution!
The SODIMM only fits in one correct orientation. It will cause
permanent damage to the development board and the SODIMM if
the SODIMM is forced into the slot at the incorrect orientation.
2.3. I/O Equipment Installation
2.3.1. 12V DC-IN
The Motherboard allows to plug in 12V DC-IN jack on the board without another
power module converter under powered consumption by Intel Atom N270
1.6GHz processor.
2.3.2. PS/2 Keyboard and PS/2 Mouse
The Motherboard provides two PS/2 interface. The PS/2 connector supports
Keyboard and Mouse. In other cases, especially in embedded solutions, a mouse is
not used. Therefore, the BIOS standard setup menu allows you to select* “All, But
Keyboard” under the “Halt On” item. This allows non-keyboard operation in
embedded system solutions without the system halting under POST.
IA71 Motherboard User Manual V1.0

2.3.3. Serial COM ports
Three RS-232 connectors build in the rear side of I/O ports. Fourth optional COM
ports support RS-232 signal. When an optional touch-screen is ordered with
Panel PC, serial COM port can connect to a serial or an optional touch-screen. One
optional COM port supports RS232/422/485 choice through jumper setting.
2.3.4. Internal VGA
The Motherboard has one VGA port that can be connected to an external CRT/
LCD monitor. Use VGA cable to connect to an external CRT / LCD monitor, and
connect the power cable to the outlet. The VGA connector is a standard 15-pin
D-SUB connector.
2.3.5. Ethernet interf ace
The Motherboard is equipped with Dual Realtek RTL8111B chipset that is fully
compliant with the PCI 10/100/1000 Mbits/s Ethernet protocol compatible. It is
supported by major network operating systems. The Ethernet ports provide two
standard RJ-45 jacks.
Two LEDs are built into the RJ-45 LAN connector where located on rear side of
the box. See as the graphic follows:
RJ-45 10/100 Ethernet LAN Connector LEDs Table

A (Green)
Off LAN link is not established

Off 10 Mbits/s data rate is selected B (Yellow)
On (steady state)

2.3.6. USB ports
IA71 Motherboard User Manual V1.0
8
The Motherboards supports up to eight USB 2.0 ports (two ports routed to the
front side of the box; four ports routed to the rear side of the box; and there are
additional two internal USB 2.0 pin headers on the Motherboard). The USB 2.0
ports are backward compatible with USB 1.1 devices. USB 1.1 devices will function
normally at USB 1.1 speeds. USB 2.0 support requires both an operating system
and drivers that fully support USB 2.0 transfer rates. Disabling Hi-Speed USB in
the BIOS revert all USB 2.0 ports to USB 1.1 operation. This may be required to
accommodate operating systems that do not support USB 2.0.
Eight USB devices (four with pin headers) may be connected to the system
through an adapter cable. Various adapters may come with the USB ports. USB
usually connect the external system to the Motherboard’s internal system. The
USB ports support hot plug-in connection function. However, you should install
the device driver program before you use the device.
NOTE
Computer systems that have an unshielded cable attached to a USB port might not
meet FCC Class B requirements, even if no device or a low-speed USB device is
attached to the cable. Use a shielded cable that meets the requirements for a
full-speed USB device.
2.3.7. Audio Jack ( Pin-header)
The Audio 5.1 channel capabilities are provided by a Realtek ALC655 chipset
which supporting digital audio outputs. The audio interface includes Mic-in,
Line-in and Line-out.
NOTE
The audio line out connector where located on rear side of the box is
designed to power headphones or amplified speakers only. Poor audio quality
occurs if passive (non-amplified) speakers are connected to this output.

2.5. Jumper Setting
A pair of needle-nose pliers may be helpful when working with jumpers. If you
have any doubts about the best hardware configuration for your application,
contact your local distributor or sales representative before you make any changes.
Generally, you simply need a standard cable to make most connections.
The jumper setting diagram is as below. If a jumper shorts pin 1 and pin 2, the
setting diagram is shown as the right one.
