1 Accessing the Components
This chapter describes how to access the internal components of the system so you can service and
upgrade your GT RAX system. This chapter also lists tools and describes methods for avoiding
electrostatic discharge, removing and replacing cover panels, and accessing components.

Before You Begin
WARNING Disconnect the system and peripheral devices from AC power before servicing
internal components! Failure to remove AC power may result in equipment
damage or personal injury. The GT RAX system is always on when connected
to AC power.
WARNING Follow all warnings and cautions in the servicing instructions. If you fail to
follow documented procedures, personal injury and damage to equipment can
result.
CAUTION Use an antistatic wrist strap for all servicing procedures to avoid the possibility of
electrostatic discharge.
“Right side” and “left side” are as seen from the front of the unit.
Tools
You will need the following tools to service the system:
♦Antistatic wrist strap
♦Quarter-inch nutdriver
♦No. 1 and No. 2 Phillips screwdrivers
♦Three-sixteenth-inch or 5 mm nutdriver
♦Five-sixteenth-inch or 8 mm nutdriver
♦Small single-slot screwdriver
Avoiding Electrostatic Discharge
Sensitive components inside the base unit can be damaged by static electricity. To protect against
this possibility, take the following precautions when working with internal components.
♦Unplug the unit from AC power before servicing any electronic component inside the chassis.
♦Touch the bare metal of the base unit to ensure the base unit and your body are at the same
electric potential.
♦Handle all printed circuit boards as little as possible and by the edges only. Leave new parts
in their protective packaging until you install them.
♦Use a disposable or reusable antistatic wrist strap when servicing or upgrading the system.
Once a disposable wrist strap is used, it cannot be used again.

3
♦Attach an antistatic wrist strap to any bare metal part of the base unit. The metal conductor in
the elastic sleeve of reusable antistatic straps must contact bare skin.
Opening the Base Unit
WARNING Before you open the base unit, shut down the system, disconnect the system
from AC power, and turn off power to external devices (including peripheral
devices and the monitor). Use caution to avoid injury when removing covers
and other hardware.
CAUTION Ensure the stabilizers of the rack in which the system is mounted are fully extended.
To open the base unit:
1. Remove the screws that secure the handles to the rack.
2. Disconnect all cables including the power cable, monitor, and all peripheral cables from the
back of the unit.
3. Slide the base unit out of the rack until it locks in the extended position.
4. Remove and retain the two screws that secure the top cover to the chassis: one each on the
upper left and upper right corners of the back of the chassis.
5. Slide the top cover back and lift it off.
6. Attach the grounding clip from the antistatic wrist strap to bare metal.
Opening and Closing the Face Panel
Face Panel Thumbscrew
(one on each side)

4
To open the face panel:
1. Open the disk drive bay door.
2. Loosen the two thumbscrews that secure the face panel to the base unit (on the upper right and
upper left corners of the face panel). See the following figure.
3. Pull the face panel toward you to open it. The face panel swings down on hinges attached to
the lower corners of the base unit. See the following figure.
To close the face panel:
1. Lift the face panel upward and push it onto the base unit.
2. Secure the face panel to the base unit by tightening the two thumbscrews.
3. Close the disk drive bay door.
Closing the Base Unit
CAUTION After servicing or upgrading the system, always replace the covers that were
removed. The covers ensure the system maintains proper air flow, so internal
components do not overheat and fail. The covers also ensure that electromagnetic
interference (EMI) emissions remain below the standard requirements.
To close the base unit:
1. Remove the antistatic wrist strap from the base unit.
2. Replace the top cover.
3. Secure the top cover to the base unit with the screws retained earlier.
4. Slide the base unit into the rack.
5. Secure the base unit to the rack by replacing the screws attaching the handles to the rack.
6. Reconnect all cables including the power cable, monitor, and peripheral cables to the back of
the system.

Before You Begin
WARNING Disconnect the system and peripheral devices from AC power before servicing
internal components! Failure to remove AC power may result in equipment
damage or personal injury. The GT RAX system is always on when connected
to AC power.
WARNING There is a danger of explosion if the battery is incorrectly replaced.
WARNING Follow all warnings and cautions in the servicing instructions. If you fail to
follow documented procedures, personal injury and damage to equipment can
result.
CAUTION Use an antistatic wrist strap for all servicing procedures to avoid the possibility of
electrostatic discharge.
CAUTION Do not overtighten screws and other fasteners to avoid damaging threads.
CAUTION Follow all warnings and cautions in these servicing instructions. If you fail to follow
documented, approved procedures, personal injury or damage to equipment can
result.
See Chapter 1, “Accessing the Components,” for details on opening the system and protecting
against electrostatic discharge. These procedures assume you have removed the cover from the
system. “Right side” and “left side” are as seen from the front of the unit. After servicing the
system, replace panels as described in Chapter 1, “Accessing the Components.”
Base Unit Components
The following figure shows the base unit components that can be replaced:
Top Cover
Face Panel
Disk Drive
Bay Door

9
To replace the disk drive bay door, you must first remove the top cover and open the face panel.
To replace the face panel, you must remove the top cover and the disk drive bay door.
To replace the top cover:
1. Remove the top cover. See Chapter 1, “Accessing the Components,” for details.
2. Install the new cover.
To replace the disk drive bay door:
1. Open the face panel. See Chapter 1, “Accessing the Components,” for details.
2. Remove the two hinge screws attaching the door to the face panel.
3. Remove the door.
4. Position the new door so that the screw holes on the door are aligned with holes in the face
panel.
5. Replace the two hinge screws, ensuring that the hinge screws are equally tightened. This will
ensure that the door is centered properly.
To replace the face panel:
1. Remove the disk drive bay door from the old face panel as described previously.
2. Install the disk drive bay door in the new face panel as described previously.
3. Remove the old face panel by removing the two shoulder screws at the bottom left and right
corners of the face panel.
4. Align the bottom of the new face panel with the front of the unit, and reattach the two shoulder
screws from step 3.
5. Close the new face panel. See Chapter 1, “Accessing the Components,” for details.
Disk Drives
This section explains how to replace the CD-ROM drive and the various disk drives in the system.
See Chapter 7, “Peripherals,” for details on drive configuration and cables.
System Disk Drive
The system disk drive is located in the uppermost part of the peripheral device bay, above the
CD-ROM and floppy disk drives, as shown in the following figure.

10
To replace the system disk drive:
1. Disconnect the power cable and SCSI cable from the disk drive.
2. Remove the four nuts (two on each side) from the vertical screws on each side of the disk
drive, and lift the disk drive out of the chassis.
3. Remove the brackets from the replaced disk drive and secure them to the new disk drive.
WARNING Handle the disk drive carefully to prevent failure and voiding the warranty for
the drive.
4. Replace the new disk drive in the chassis and secure it with the four nuts removed previously.
5. Connect the power cable and SCSI cable to the disk drive.
You will need to reinstall the operating system and associated system software on the new system
disk drive. See System Setup for more information.
CD-ROM Drive
To replace the CD-ROM drive:
1. For ease of access, remove the chassis fan as described later in “Chassis Fan.”
