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.
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.
Refer to the illustrations below for examples of what the
2-pin and 3-pin jumpers look like when they are short (on)
and open (off).
The figure on the right is the NSB 3130
main board which is the main board
used in the NSA 3130 system. It shows
the locations of the jumpers and connectors.
11. The mounting holes around the CPU socket are used to
mount the heat sink. Align the mounting screws of the
heat sink with the mounting holes on the board. Tighten
the screws to secure the heat sink in place.
1. The 2 DDR3 sockets are divided into 2 channels.
• DIMM1 = Channel A
DIMM2 = Channel B
• Always populate DIMM1 first. The
Push the ejector tabs which are at the ends of the socket
outward. This indicates that the socket is unlocked.
system will not boot when the first
module is installed in DIMM2.
2. Note how the module is keyed to the socket. Grasping
the module by its edges, align the module with the
socket so that the “notch” on the module is aligned with
the “key” on the socket. The key ensures the module can
be plugged into the socket in only one direction.
3. Seat the module vertically, pressing it down firmly until it
is completely seated in the socket. The ejector tabs at the
ends of the socket will automatically snap into the locked
position to hold the module in place.
3. Place the SATA hard drive onto the drive bay. Align the
mounting holes that are on the sides of the SATA drive
with the mounting holes on the drive bay. Use the
provided mounting screws to secure the SATA drive in
place.
3. Insert the connector located on the solder side of the
SATA DOM to the SATA connector that is on the board.
Secure the SATA DOM with the provided mounting screw
then connect the power cable to the power connector on
the board.
This chapter describes how to use the BIOS setup program
for NSA3130. The BIOS screens provided in this chapter are
for reference only and may change if the BIOS is updated in
the future.
To check for the latest updates and revisions, visit the
NEXCOM Web site at www.nexcom.com.tw
About BIOS Setup
The BIOS (Basic Input and Output System) Setup program
is a menu driven utility that enables you to make changes
to the system configuration and tailor your system to suit
your individual work needs. It is a ROM-based
configuration utility that displays the system’s
configuration status and provides you with a tool to set
system parameters.
These parameters are stored in non-volatile
battery-backed-up CMOS RAM that saves this information
even when the power is turned off. When the system is
turned back on, the system is configured with the values
found in CMOS.
With easy-to-use pull down menus, you can configure such
items as:
• Hard drives, diskette drives, and peripherals
• Video display type and display options
.
• Password protection from unauthorized use
• Power management features
The settings made in the setup program affect how the
computer performs. It is important, therefore, first to try
to understand all the Setup options, and second, to make
settings appropriate for the way you use the computer.
When to Configure the BIOS
This program should be executed under the following
conditions:
• When changing the system configuration
• When a configuration error is detected by the
system and you are prompted to make changes to
the Setup program
• When resetting the system clock
• When redefining the communication ports to
prevent any conflicts
• When making changes to the Power Management
configuration
• When changing the password or making other
changes to the security setup
Normally, CMOS setup is needed when the system
hardware is not consistent with the information contained
in the CMOS RAM, whenever the CMOS RAM has lost
power, or the system features need to be changed.
Most of the configuration settings are either predefined
according to the Load Optimal Defaults settings which
are stored in the BIOS or are automatically detected and
configured without requiring any actions. There are a
few settings that you may need to change depending on
your system configuration.
Entering Setup
When the system is powered on, the BIOS will enter the
Power-On Self Test (POST) routines. These routines
perform various diagnostic checks; if an error is
encountered, the error will be reported in one of two
different ways:
•If the error occurs before the display device is
initialized, a series of beeps will be transmitted.
• If the error occurs after the display device is
initialized, the screen will display the error message.
Powering on the computer and immediately pressing
<Del> allows you to enter Setup. Another way to enter
Setup is to power on the computer and wait for the
following message during the POST:
TO ENTER SETUP BEFORE BOOT PRESS
<CTRL-ALT-ESC> Press the <Del> key to enter
