Regulatory Compliance Statements

This section provides the FCC compliance statement for Class A devices and

describes how to keep the system CE compliant.

Declaration of Conformity

FCC

This equipment has been tested and verified to comply with the limits for

a Class A digital device, pursuant to Part 15 of FCC Rules. These limits are

designed to provide reasonable protection against harmful interference when

the equipment is operated in a commercial environment. This equipment

generates, uses, and can radiate radio frequency energy and, if not installed

and used in accordance with the instructions, may cause harmful interference

to radio communications. Operation of this equipment in a residential area

(domestic environment) is likely to cause harmful interference, in which

case the user will be required to correct the interference (take adequate

measures) at their own expense.

The product(s) described in this manual complies with all applicable

European Union (CE) directives if it has a CE marking. For computer systems

to remain CE compliant, only CE-compliant parts may be used. Maintaining

CE compliance also requires proper cable and cabling techniques.

Preface

RoHS Compliance

NexAIoT RoHS Environmental Policy and Status

Update

NexAIoT is a global citizen for building the digital

infrastructure. We are committed to providing green

products and services, which are compliant with

European Union RoHS (Restriction on Use of Hazardous Substance in

Electronic Equipment) directive 2011/65/EU, to be your trusted green

partner and to protect our environment.

RoHS restricts the use of Lead (Pb) < 0.1% or 1,000ppm, Mercury (Hg) < 0.1%

or 1,000ppm, Cadmium (Cd) < 0.01% or 100ppm, Hexavalent Chromium

(Cr6+) < 0.1% or 1,000ppm, Polybrominated biphenyls (PBB) < 0.1% or

1,000ppm, and Polybrominated diphenyl Ethers (PBDE) < 0.1% or 1,000ppm.

In order to meet the RoHS compliant directives, NexAIoT has established an

engineering and manufacturing task force to implement the introduction

of green products. The task force will ensure that we follow the standard

NexAIoT development procedure and that all the new RoHS components

and new manufacturing processes maintain the highest industry quality

levels for which NexAIoT are renowned.

The model selection criteria will be based on market demand. Vendors and

suppliers will ensure that all designed components will be RoHS compliant.

How to recognize NexAIoT RoHS Products?

For existing products where there are non-RoHS and RoHS versions, the

suffix “(LF)” will be added to the compliant product name.

All new product models launched after January 2013 will be RoHS compliant.

They will use the usual NexAIoT naming convention.

Preface

Warranty and RMA

Preface

Warnings

Read and adhere to all warnings, cautions, and notices in this guide and

the documentation supplied with the chassis, power supply, and accessory

modules. If the instructions for the chassis and power supply are inconsistent

with these instructions or the instructions for accessory modules, contact

the supplier to find out how you can ensure that your computer meets

safety and regulatory requirements.

Cautions

Electrostatic discharge (ESD) can damage system components. Do the

described procedures only at an ESD workstation. If no such station is

available, you can provide some ESD protection by wearing an antistatic

wrist strap and attaching it to a metal part of the computer chassis.

Installation Recommendations

Ensure you have a stable, clean working environment. Dust and dirt can get

into components and cause a malfunction. Use containers to keep small

components separated.

Adequate lighting and proper tools can prevent you from accidentally

damaging the internal components. Most of the procedures that follow

require only a few simple tools, including the following:

▪A Philips screwdriver

▪A flat-tipped screwdriver

▪A grounding strap

▪An anti-static pad

Using your fingers can disconnect most of the connections. It is recommended

that you do not use needle-nose pliers to disconnect connections as these

can damage the soft metal or plastic parts of the connectors.

Preface
