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.
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 NANO-CV-D25501/N26001 is unpacked, please do the following:
Follow the antistatic guidelines above.  Make sure the packing box is facing upwards whe n 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 NANO-CV-D25501/N26001 may result in permanent damage to the NANO-CV-D25501/N26001 and severe injury to the user.
Electrostatic discharge (ESD) can cause serious damage to electronic components, including the NANO-CV-D25501/N26001. Dry climates are especially susceptible to ESD. It is therefore critical that whenever the NANO-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 NANO-CV-D25501/N26001,
place it on an anti-static pad. This re duces the possibility of ESD damaging the NANO-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 45
Page 60
NANO-CV-D25501/N26001 EPIC 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
NANO-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 NANO-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 NANO-CV-D25501/N26001 off:
o When working with the NANO-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 NANO-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.
Allow screws to come in contact with the PCB circuit, connector pins, or its
Page 46
components.

4.3 SO-DIMM Installation

WARNING:
Using incorrectly specified SO-DIMM may cause permanent damage to the NANO-CV-D25501/N26001. Please make sure the purchased SO-DIMM complies with the memory specifications of the NANO-CV-D25501/N26001. SO-DIMM specifications compliant with the NANO-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 NANO-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: Seat the SO-DIMM. Gently push downwards and the arms clip into place.

4.4 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.

4.5 Chassis Installation

4.5.1 Airflow

WARNING:
Airflow is critical to the cooling of the CPU and other on-board components. The chassis in which the NANO-CV-D25501/N26001 must have air vents to allow cool air to move into the system and hot air to move out.
The NANO-CV-D25501/N26001 must be installed in a chassis with ventilation holes on the sides allowing airflow to travel through the heat sink surface. In a system with an individual power supply unit, the cooling fan of a power supply can also help generate airflow through the board surface.
NOTE:
IEI has a wide range of chassis available. Please contact your NANO-CV-D25501/N26001 vendor, reseller or an IEI sales representative at (

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.
