2.1 Anti-static Precautions

WARNING!

Static electricity can destroy certain electronics. Make sure to follow the
ESD precautions to prevent damage to the product, and injury to the
user.

Make sure to adhere to the following guidelines:

 Wear an anti-static wristband: Wearing an anti-static wristband can prevent

electrostatic discharge.

 Self-grounding: Touch a grounded conductor every few minutes to discharge

any excess static buildup.

WAFER-CV-D25501/N26001 3.5" SBC

 Use an anti-static pad: When configuring any circuit board, place it on an

anti-static mat.

 Only handle the edges of the PCB: Don't touch the surface of the

motherboard. Hold the motherboard by the edges when handling.

2.2 Unpacking Precautions

When the WAFER-CV-D25501/N26001 is unpacked, please do the following:

 Follow the antistatic guidelines above.
 Make sure the packing box is facing upwards when opening.
 Make sure all the packing list items are present.

4.1 Anti-static Precautions

WARNING:

Failure to take ESD precautions during the installation of the
WAFER-CV-D25501/N26001 may result in permanent damage to the
WAFER-CV-D25501/N26001 and severe injury to the user.

Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the WAFER-CV-D25501/N26001. Dry climates are especially susceptible to
ESD. It is therefore critical that whenever the WAFER-CV-D25501/N26001 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

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 W A FER-CV-D25501/N26001,

place it on an anti-static pad. This re duces the possibility of ESD damaging
the WAFER-CV-D25501/N26001.

 Only handle the edges of the PCB:-: When handling the PCB, hold the PCB

by the edges.

4.2 Installation Considerations

NOTE:

The following installation notices and installation considerations should
be read and understood before installation. All installation notices must
be strictly adhered to. Failing to adhere to these precautions may lead
to severe damage and injury to the person performing the installation.

Page 39

WAFER-CV-D25501/N26001 3.5" SBC

WARNING:

The installation instructions described in this manual should be
carefully followed in order to prevent damage to the components and
injury to the user.

Before and during the installation please DO the following:

 Read the user manual:

o The user manual provides a complete description of the

WAFER-CV-D25501/N26001 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 the body and helps prevent ESD damage.

 Place the WAFER-CV-D25501/N26001 on an antistatic pad:

o When installing or configuring the motherboard, place it on an antistatic

pad. This helps to prevent potential ESD damage.

 Turn all power to the W A FER-CV-D25501/N26001 off:

o When working with the WAFER-CV-D25501/N26001, 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 WAFER-CV-D25501/N26001 DO NOT:

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

warranty validation.

 Use the product before verifying all the cables and power connectors are

properly connected.

Page 40

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

components.

4.3 SO-DIMM Installation

WARNING:

Using incorrectly specified SO-DIMM may cause permanent damage to
the WAFER-CV-D25501/N26001. Please make sure the purchased
SO-DIMM complies with the memory specifications of the
WAFER-CV-D25501/N26001. SO-DIMM specifications compliant with
the WAFER-CV-D25501/N26001 are listed in Chapter 1.

To install a SO-DIMM into a SO-DIMM socket, please follow the steps below and refer to

Figure 4-1.

Figure 4-1: SO-DIMM Installation

Step 1: Locate the SO-DIMM socket. Place the WAFER-CV-D25501/N26001 on an

anti-static pad with the solder side facing up.

Step 2: Align the SO-DIMM with the socket. The SO-DIMM must be oriented in such a

way that the notch in the middle of the SO-DIMM must be aligned with the
plastic bridge in the socket.

Step 3: Insert the SO-DIMM. Push the SO-DIMM chip into the socket at an angle. (See

Figure 4-1)

Step 4: Open the SO-DIMM socket arms. Gently pull the arms of the SO-DIMM socket

out and push the rear of the SO-DIMM down. (See

Figure 4-1)

Page 41

Step 5: Secure the SO-DIMM. Release the arms on the SO-DIMM socket. They clip into

place and secure the SO-DIMM in the socket.Step 0:

4.4 Jumper Settings

NOTE:

A jumper is a metal bridge used to close
an electrical circuit. It consists of two or
