3.4 Onboard Jumpers

NOTE:

A jumper is a metal bridge that is used to

close an electrical circuit. 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/SHORT a jumper mean

connecting the pins of the jumper with

the plastic clip and to OPEN a jumper

means removing the plastic clip from a

jumper.

The Enano-8523T board has three one onboard jumpers, “Clear CMOS,” “CF card setup”

and “LCD voltage setup.”

4 Installation and

Configuration

1-61

4.1 Installation Considerations

NOTE:

The following installation notices and installation considerations should be

read and understood before the Enano-8523T is installed. All installation

notices pertaining to the installation of the Enano-8523T should be strictly

adhered to. Failing to adhere to these precautions may lead to severe

damage of ENANP-8523 and injury to the person installing the ENANO-853.

4.1.1 Installation Notices

Before and during the installation of the Enano-8523T board, please do the following:

 Read the user manual

o The user manual provides a complete description of the

Enano-8523T board, installation instructions and configuration

options.

 Wear an electrostatic discharge cuff (ESD)

o Electronic components are easily damaged by ESD. Wearing an ESD

cuff removes ESD from your body and help to prevent ESD damage.

 Place the board on an antistatic pad

o When you are installing or configuring the board, place it on an

antistatic pad. This helps to prevent potential ESD damage.

 Turn off all power to the Enano-8523T board

o When working with the board, make sure that it is disconnected from

all power supplies and that no electricity is being fed into the system.

Before and during the installation of the Enano-8523T board DO NOT:

 remove any of the stickers on the PCB board. These stickers are required for

warranty validation.

 use the product before you have verified that all cables and power connectors

are properly connected.

1-62

IEI

Technology, Corp.

 allow screws to come in contact with the PCB circuit, connector pins, or its

components.

4.2 Unpacking

NOTE:

If any of the items listed below are missing when you unpack the

Enano-8523T board, do not proceed with the installation and contact the

reseller or vendor you purchased the board from.

Enano-8523T Motherboard

4.2.1 Unpacking Precautions

Before you install the Enano-8523T board, you must unpack the board. Some

Enano-8523T components are very sensitive to static electricity and can be damaged by a

sudden rush of power. To protect it from being damage, follow these precautions:

 Ground yourself to remove any static charge before touching your

Enano-8523T. You can do so by wearing a grounded wrist strap at all times or

by frequently touching any conducting materials that are connected to the

ground.

 Handle your Enano-8523T by its edges. Do not touch the IC chips, leads or

circuitry if not necessary.

Do not place a PCB on top of an anti-static bag. Only the inside of the bag is safe from

static discharge.

4.2.2 Checklist

When you unpack the Enano-8523T, please make sure that your package contains the

following items.

 1 x Enano-8523T single board computer  1 x Keyboard/ PS2 mouse cable

1-63

 1 x Mini jumper pack  1 x Utility CD  1 x IDE flat cable 44p/44p  1 x QIG (quick installation guide)
