Chapter 2: Setting Up

2.0.1 Before You Begin

This chapter explains how to install the CPU, CPU heatsink,
memory modules, and hard drives. Instructions on inserting a
PCI-X card are also given.

Take note of the precautions mentioned in this section when
installing your system.

2.0.2 Work Area

Make sure you have a stable, clean working environment.
Dust and dirt can get into components and cause malfunc­tions. Use containers to keep small components separated.
Putting all small components in separate containers prevents
them from becoming lost. Adequate lighting and proper tools
can prevent you from accidentally damaging the internal
components.

2.0.3 Tools

The following procedures require only a few tools, including
the following:

• A cross head (Phillips) screwdriver

• A grounding strap or an anti-static pad

Most of the electrical and mechanical connections can be dis­connected using your fingers. It is recommended that you do
not use needle-nosed pliers to remove connectors as these
can damage the soft metal or plastic parts of the connectors.

12 Chapter 2: Setting Up

2.0.4 Precautions

Components and electronic circuit boards can be damaged
by discharges of static electricity. Working on a system that is
connected to a power supply can be extremely dangerous.
Follow the guidelines below to avoid damage to the
Transport GT20 or injury to yourself.

• Ground yourself properly before removing the top

cover of the system. Unplug the power from the
power supply and then touch a safely grounded
object to release static charge (i.e. power supply
case). If available, wear a grounded wrist strap. 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.

• Avoid touching motherboard components, IC chips,

connectors, memory modules, and leads.

• The motherboard is pre-installed in the system.

When removing the motherboard, always place it on
a grounded anti-static surface until you are ready to
reinstall it.

• Hold electronic circuit boards by the edges only. Do

not touch the components on the board unless it is
necessary to do so. Do not flex or stress circuit
boards.

• Leave all components inside the static-proof packag-

ing that they ship with until they are ready for installa­tion.

• After replacing optional devices, make sure all

screws, springs, or other small parts are in place and
are not left loose inside the case. Metallic parts or
metal flakes can cause electrical shorts.

Notes:

• All connectors are keyed to only attach one way.

• Always use the correct screw size as indicated in the
procedures.

Chapter 3: Replacing Pre-Installed

Components

3.1 Introduction

This chapter explains how to replace pre installed compo­nents including the motherboard, LED control board, HDD,
and CD-ROM drive.

Take note of the precautions in this section when installing
your system.

3.1.1 Work Area

Make sure you have a stable, clean working environment.
Dust and dirt can get into components and cause malfunc­tions. Use containers to keep small components separated.
Putting all small components in separate containers keeps
them from becoming lost. Adequate lighting and proper tools
can prevent you from accidentally damaging the internal
components.

3.1.2 Tools

The procedures that follow require only a few tools, including
the following:

• A cross head (Phillips) screwdriver

• A grounding strap or an anti-static pad

Most of the electrical and mechanical connections can be dis­connected using your fingers. It is recommended that you do
not use needle-nosed pliers to remove connectors as these
can damage the soft metal or plastic parts of the connectors.

32 Chapter 3: Replacing Pre-Installed Components

3.1.3 Precautions

Components and electronic circuit boards can be damaged
by static electricity. Working on a system that is connected to
a power supply can be extremely dangerous. Follow the
guidelines below to avoid damage to the Transport GT20 or
injury to yourself.

• Ground yourself properly before removing the top

cover of the system. Unplug the power from your
computer power supply and then touch a safely
grounded object to release static charge (i.e. power
supply case). If available, wear a grounded wrist
strap. 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.

• Avoid touching motherboard components, IC chips,

connectors, memory modules, and leads.

• The motherboard is pre-installed in the system.

When removing the motherboard, always place it on
a grounded anti-static surface until you are ready to
reinstall it.

• Hold electronic circuit boards by the edges only. Do

not touch the components on the board unless it is
necessary to do so. Do not flex or stress circuit
boards.

• Leave all components inside the static-proof packag-

ing that they ship with until they are ready for installa­tion.

• After replacing optional devices, make sure all

screws, springs, or other small parts are in place and
are not left loose inside the case. Metallic parts or
metal flakes can cause electrical shorts.

Notes:

• All connectors are keyed to only attach one way.

• Always use the correct screw size as indicated in the
procedures.

contains. Hence, they should be of the most assistance for
you. Furthermore, if you purchased your system from a
dealer near you, take the system to them directly to have it
serviced instead of attempting to do so yourself (which can
have expensive consequences).
