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.

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.

or in a above 40oC storage temperature as this may damage the
equipment.
8. The openings on the enclosure are for air convection to protect the
equipment from overheating. DO NOT COVER THE OPENINGS.
9. Make sure the voltage of the power source is correct before connect-
ing the equipment to the power outlet.
10. Place the power cord in a way so that people will not step on it. Do
not place anything on top of the power cord. Use a power cord that
has been approved for use with the product and that it matches the
voltage and current marked on the product’s electrical range label.
The voltage and current rating of the cord must be greater than the
voltage and current rating marked on the product.
11. All cautions and warnings on the equipment should be noted.
12. If the equipment is not used for a long time, disconnect it from the
power source to avoid damage by transient overvoltage.
13. Never pour any liquid into an opening. This may cause fire or electri-
cal shock.
14. Never open the equipment. For safety reasons, the equipment should
be opened only by qualified service personnel.
15. If one of the following situations arises, get the equipment checked
by service personnel:
a. The power cord or plug is damaged.
b. Liquid has penetrated into the equipment.
c. The equipment has been exposed to moisture.
d. The equipment does not work well, or you cannot get it to work
according to the user’s manual.
e. The equipment has been dropped and damaged.
f. The equipment has obvious signs of breakage.
16. Do not place heavy objects on the equipment.
17. The unit uses a three-wire ground cable which is equipped with a
third pin to ground the unit and prevent electric shock. Do not defeat
the purpose of this pin. If your outlet does not support this kind of
plug, contact your electrician to replace your obsolete outlet.
18. CAUTION: DANGER OF EXPLOSION IF BATTERY IS INCORRECTLY
REPLACED. REPLACE ONLY WITH THE SAME OR EQUIVALENT TYPE
RECOMMENDED BY THE MANUFACTURER. DISCARD USED BATTER-
IES ACCORDING TO THE MANUFACTURER’S INSTRUCTIONS.

Chapter 2: Jumpers and Connectors
NDiS 162 User Manual
This chapter describes how to set the jumpers on the motherboard. Note
that the following procedures are generic for all NDiS 162 series.
Before You Begin
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 set of jewelers Screwdrivers•
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 needle-nosed pliers to disconnect connec-
tions as these can damage the soft metal or plastic parts of the connec-
tors.
Before working on internal components, make sure that the power
•
is off. Ground yourself before touching any internal components, by
touching a metal object. Static electricity can damage many of the elec-
tronic components. Humid environment tend to have less static electric-
ity than dry environments. A grounding strap is warranted whenever
danger of static electricity exists.
Precautions
Computer components and electronic circuit boards can be damaged by
discharges of static electricity. Working on the computers that are still con-
nected to a power supply can be extremely dangerous.
Follow the guidelines below to avoid damage to your computer or your-
self:
Always disconnect the unit from the power outlet whenever you are
•
working inside the case.
If possible, wear a grounded wrist strap when you are working inside
•
the computer case. Alternatively, discharge any static electricity by
touching the bare metal chassis of the unit case, or the bare metal body
of any other grounded appliance.
Hold electronic circuit boards by the edges only. Do not touch the com-
•
ponents on the board unless it is necessary to do so. Don’t flex or stress
the circuit board.
Leave all components inside the static-proof packaging that they
•
shipped with until they are ready for installation.
Use correct screws and do not over tighten screws.

Jumper Settings
A jumper is the simplest kind of electric switch. It consists of two metal
pins and a cap. When setting the jumpers, ensure that the jumper caps are
placed on the correct pins. When the jumper cap is placed on both pins,
the jumper is short. If you remove the jumper cap, or place the jumper
