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.
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
manufacturer. 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.

5. Keep this equipment away from humidity.
6. Put this equipment on a stable surface during installation. Dropping
it or letting it fall may cause damage.
7. Do not leave this equipment in either an unconditioned environment
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
connecting 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
electrical 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
BATTERIES ACCORDING TO THE MANUFACTURER’S
INSTRUCTIONS.
19. The computer is provided with CD drives that comply with the ap-
propriate safety standards including IEC 60825.

Chapter 2: Jumpers and Connectors
This chapter describes the jumpers and connectors on the
motherboard. Note that information in this chapter applies
to NSA 3130.
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 recommended that you do not use
needle-nosed pliers to disconnect connections as these
can damage the soft metal or plastic parts of the
connectors.
• 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 electronic
components. Humid environment tend to have less static
electricity 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 connected to a power supply can
be extremely dangerous.
Follow the guidelines below to avoid damage to your
computer or yourself:
•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 components 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
cap on just one pin, the jumper is open.
