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 equip-
ment 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 interfer-
ence, in which case the user will be required to correct the interference
(take adequate measures) at their own expense.
CE
The product(s) described in this manual complies with all applicable Euro-
pean 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.

and services, which are compliant with European Union
RoHS (Restriction on Use of Hazardous Substance in Electronic Equipment)
directive 2002/95/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, NEXCOM has established an
engineering and manufacturing task force in to implement the introduction
of green products. The task force will ensure that we follow the standard
NEXCOM development procedure and that all the new RoHS components
and new manufacturing processes maintain the highest industry quality
levels for which NEXCOM 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 NEXCOM RoHS Products?
For existing products where there are non-RoHS and RoHS versions, the suf-
fix “(LF)” will be added to the compliant product name.
All new product models launched after January 2006 will be RoHS compli-
ant. They will use the usual NEXCOM naming convention.

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 incon-
sistent 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 de-
scribed procedures only at an ESD workstation. If no such station is avail-
able, you can provide some ESD protection by wearing an antistatic wrist
strap and attaching it to a metal part of the computer chassis.
Safety Information
Before installing and using the device, note the following precautions:
▪Read all instructions carefully.
▪Do not place the unit on an unstable surface, cart, or stand.
▪Follow all warnings and cautions in this manual.
▪When replacing parts, ensure that your service technician uses parts
specified by the manufacturer.
▪Avoid using the system near water, in direct sunlight, or near a heating
device.
▪The load of the system unit does not solely rely for support from the
rackmounts located on the sides. Firm support from the bottom is highly
necessary in order to provide balance stability.
▪The computer is provided with a battery-powered real-time clock circuit.
There is a danger of explosion if battery is incorrectly replaced. Replace
only with the same or equivalent type recommended by the manufactur-
er. Discard used batteries according to the manufacturer’s instructions.
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 recom-
mended that you do not use needlenose pliers to disconnect connections
as these can damage the soft metal or plastic parts of the connectors.

a above 60oC storage temperature as this may damage the board.
8. Wear an antistatic wrist strap.
9. Do all preparation work on a static-free surface.
10. Hold the board only by its edges. Be careful not to touch any of the
components, contacts or connections.
11. All cautions and warnings on the board should be noted.
