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.

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 recommended that you do not use needlenose pliers to disconnect connections as these can damage the soft metal or plastic parts of the connectors.

Chapter 2: Jumpers and Connectors

Chapter 2: Jumpers and ConneCtors

This chapter describes how to set the jumpers and connectors on the NEX 880/890 motherboard.

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 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 elec-

tronic 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 com-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 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).

Two-Pin Jumpers: Open (Left) and Short (Right)

Three-Pin Jumpers: Pins 1 and 2 Are Short

Chapter 3: BIOS Setup

This chapter describes how to use the BIOS setup program for the NEX 880/890. 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.

NEX 880/890 User Manual

Chapter 3: BIOS Setup

Default Configuration

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 Setup:
