1. Getting Started
1.1 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 electronics 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.
1.2 Packing List
Before you begin installing your single board, please make sure that the
following materials have been shipped:
1 x ESM-EHLC COMe Module
1 x Desiccant (5g)
4 x Screws

1.4 Manual Objectives
This manual describes in details Avalue Technology ESM-EHLC Single Board.
We have tried to include as much information as possible but we have not duplicated
information that is provided in the standard IBM Technical References, unless it proved to
be necessary to aid in the understanding of this board.
We strongly recommend that you study this manual carefully before attempting to set up
ESM-EHLC series or change the standard configurations. Whilst all the necessary
information is available in this manual we would recommend that unless you are confident,
you contact your supplier for guidance.
Please be aware that it is possible to create configurations within the NVRAM that make
booting impossible. If this should happen, clear the NVRAM settings, (see the description of
the Jumper Settings for details).
If you have any suggestions or find any errors regarding this manual and want to inform us
of these, please contact our Customer Service department with the relevant details.

2.2 Connector List
You can configure your board to match the needs of your application by setting jumpers. A
jumper is the simplest kind of electric switch.
It consists of two metal pins and a small metal clip (often protected by a plastic cover) that
slides over the pins to connect them. To “close” a jumper you connect the pins with the clip.
To “open” a jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1,
2, and 3. In this case, you would connect either two pins.
The jumper settings are schematically depicted in this manual as follows:
A pair of needle-nose pliers may be helpful when working with jumpers.
Connectors on the board are linked to external devices such as hard disk drives, a
keyboard, or floppy drives. In addition, the board has a number of jumpers that allow you to
configure your system to suit your application.
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.
The following tables list the function of each of the board’s jumpers and connectors.
