2.1 Anti-static Precautions
WARNING:
Failure to take ESD precautions during installation may result in
permanent damage to the ECW-281B-D2550 and severe injury to the
user.
Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the ECW-281B-D2550. Dry climates are especially susceptible to ESD. It is
therefore critical that whenever the ECW-281B-D2550 or any other electrical component
is handled, the following anti-static precautions are strictly adhered to.
Wear an anti-static wristband: Wearing a simple anti-static wristband can
ECW-281B-D2550 Embedded System
help to prevent ESD from damaging the board.
Self-grounding: Before handling the board touch any grounded conducting
material. During the time the board is handled, frequently touch any
conducting materials that are connected to the ground.
Use an anti-static pad: When configuring the ECW-281B-D2550, place it on
an antic-static pad. This reduces the possibility of ESD damaging the
ECW-281B-D2550.
2.2 Unpacking Precautions
When the ECW-281B-D2550 is unpacked, please do the following:
Follow the anti-static precautions outlined in Section
Make sure the packing box is facing upwards so the ECW-281B-D2550 does
not fall out of the box.
Make sure all the components shown in Section
2.1.
2.3 are present.

Page 15
3.1 Installation Precautions
During installation, be aware of the precautions below:
Read the user manual: The user manual provides a complete description of
the ECW-281B-D2550, installation instructions and configuration options.
DANGER! Disconnect Power: Power to the ECW-281B-D2550 must be
disconnected during the installation process. Failing to disconnect the power
may cause severe injury to the body and/or damage to the system.
Qualified Personnel: The ECW-281B-D2550 must be installed and operated
only by trained and qualified personnel. Maintenance, upgrades, or repairs
may only be carried out by qualified personnel who are familiar with the
associated dangers.
Air Circulation: Make sure there is sufficient air circulation when installing the
ECW-281B-D2550. The ECW-281B-D2550’s cooling vents must not be
ECW-281B-D2550 Embedded System
obstructed by any objects. Blocking the vents can cause overheating of the
ECW-281B-D2550. Leave at least 5 cm of clearance around the
ECW-281B-D2550 to prevent overheating.
Grounding: The ECW-281B-D2550 should be properly grounded. The
voltage feeds must not be overloaded. Adjust the cabling and provide external
overcharge protection per the electrical values indicated on the label attached
to the back of the ECW-281B-D2550.
3.2 Bottom Surface Removal
WARNING:
Over-tightening bottom cover screws will cause damage to the bottom
surface. Maximum torque for cover screws is 5 kg-cm (0.36 lb-ft/0.49 Nm).
Before accessing the internal components of the ECW-281B-D2550, the bottom surface
Page 16
must be removed. To remove the bottom surface, please follow the steps below:
ECW-281B-D2550 Embedded System
Step 1: Remove the bottom surface retention screws. The bottom surface is secured to
the chassis with ten retention screws (
765Figure 3-1). All ten screws must be
removed.

3.6 Jumper Settings
NOTE:
A jumper is a metal bridge used to close an
electrical circuit. It consists of two or three metal
pins and a small metal clip (often protected by a
plastic cover) that slides over the pins to connect
them. To CLOSE/SHORT a jumper means
connecting the pins of the jumper with the plastic
clip and to OPEN a jumper means removing the
plastic clip from a jumper.
The jumpers on the ECW-281B-D2550 motherboard are listed in 5Table 3-1.

4.1 System Maintenance Introduction
The following system components may require maintenance.
Motherboard
SO-DIMM module
If these components fail, they must be replaced. Please contact the system reseller or
vendor to purchase replacement parts. Replacement instructions for the above listed
components are described below.
WARNING!
Before accessing any ECW-281B-D2550 internal components, make
sure all power to the system has been disconnected. Failing to do so
may cause severe damage to the ECW-281B-D2550 and injury to the
user.
WARNING!
Please take antistatic precautions when working with the internal
components. The interior of the ECW-281B-D2550 contains very
sensitive electronic components. These components are easily
damaged by electrostatic discharge (ESD). Before working with the
internal components, make sure all anti-static precautions described
earlier have been observed.
4.2 Motherboard Replacement
A user cannot replace a motherboard. If the motherboard fails it must be shipped back to
IEI to be replaced. If the system motherboard has failed, please contact the system vendor,
reseller or an IEI sales person directly.
Page 45
4.3 SO-DIMM Replacement
To install/replace the SO-DIMM modules, please follow the steps below.
Step 1: Remove the bottom surface panel. Place the ECW-281B-D2550 on an
anti-static pad with the bottom panel facing up and the bottom surface removed.

5.1 Introduction
The BIOS is programmed onto the BIOS chip. The BIOS setup program allows changes to
certain system settings. This chapter outlines the options that can be changed.
5.1.1 Starting Setup
The UEFI BIOS is activated when the computer is turned on. The setup program can be
activated in one of two ways.
1. Press the DEL or F2 key as soon as the system is turned on or
2. Press the DEL or F2 key when the “Press DEL or F2 to enter SETUP”
message appears on the screen.
If the message disappears before the DEL or F2 key is pressed, restart the computer and
try again.
5.1.2 Using Setup
Use the arrow keys to highlight items, press ENTER to select, use the PageUp and
PageDown keys to change entries, press F1 for help and press E
keys are shown in the following table.
