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.

Preface
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 needle-nose pliers to disconnect connections as these
can damage the soft metal or plastic parts of the connectors.
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.

Chapter 2: Jumpers and Connectors
ChaPter 2: JumPers and ConneCtors
This chapter describes how to set the jumpers and connectors on the
DTA1164W 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
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 environments 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 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.

Chapter 2: Jumpers and Connectors
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
