1 Accessing the System
The TDZ 2000 GT1 features an extensible chassis architecture designed for ease of upgrades
and expansion. The design provides easy access to AGP, PCI, and ISA card slots, memory,
processors, and power supply.
This chapter lists hand tools and describes servicing restrictions, methods for avoiding
electrostatic discharge, and how to remove and attach cover panels.

Before You Begin
NOTE “Right side” and “left side” are as seen from the front of the unit.
CAUTION Follow all warnings and cautions in the servicing instructions. If you fail to follow documented,
approved 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 use the bottom portion of the face panel or the lip at the top, rear of the unit as a hand
hold when moving the system. Equipment damage and personal injury can result.
Tools
You will need the following tools to service the system:

Antistatic wrist strap

Antistatic mat connected to an earth ground

Quarter-inch nutdriver

No. 1 and No. 2 Phillips screwdrivers

Small or medium flat-blade standard screwdriver
You do not need any tools to open the TDZ 2000 GT1 case.
Protecting Against Electrostatic Discharge
Electrostatic discharge (ESD) can damage sensitive components inside the unit. Take the
following precautions when working with internal components:

Slide the antistatic wrist strap onto your wrist, and then attach the antistatic cable.
Connect the cable to the a bare section of the chassis. Ensure that the metal conductor
bead in the elastic sleeve of the antistatic strap contacts bare skin.
Unplug the unit from AC power before servicing any electronic component inside the chassis.
Remember that the TDZ 2000 GT1 is always on when connected to AC power.

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.

3
Opening and Closing the Case
Opening the system for service or upgrades consists of two simple steps. Remove the top
cover first, then remove the left side panel. No tools are needed. You need only remove the
top cover and left side panel for most routine service procedures. See Chapter 2, “Servicing
the System,” for additional details on removing and replacing case components.
The left side panel has a tab that closes an interlock switch inside the power supply. When
you take off the left side panel, the safety interlock removes AC power to the system.
WARNING Do not attempt to defeat the safety interlock and run the system with the left side panel
removed. Personal injury and equipment damage can result.
CAUTION Before you open the case, shut down the system and turn off power to the system and
external devices (including peripheral drives and display). Use caution to avoid injury when
lifting the computer or removing covers and other hardware.
NOTE Removing the right side panel is necessary only for servicing internal bay disk drives, the
plastic cowling on the right panel, or the face panel.
To open the case:
1. Ensure the system is shut down and that you have disconnected the system and any
attached external devices from AC power.
2. Grasp the lip on the top cover at the rear of the system and press up on the release. See
the following figure.
Press up on release located under lip

4
3. Keep pressing the release, slide the top cover back until it stops, remove it from the
chassis, and set it aside.
4. Grasp the cowling at the bottom of the left side panel and lift.
5. Slide the left side panel back until it stops, remove it from the chassis, and set it aside.
6. Repeat steps 4 and 5 to remove the right side panel, if necessary.
To close the case:
1. Place the side panel on the chassis so that all tabs on the rear of the chassis insert into
their slots.
NOTE When installing the left side panel, ensure that the security tab aligns with its corresponding
slot on the panel.
2. Push the side panel toward the front of the chassis, then push down to seat the panel.
3. Repeat steps 1 and 2 to install the remaining side panel, if necessary.
4. Place the top cover on the chassis so that all tabs are inserted into their slots.
5. Slide the top cover forward until it locks into place.
CAUTION After servicing or upgrading the system, always replace the covers that were removed. Do not
defeat the AC interlock. 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.

Accessing Components Behind the Power Supply
To access the processors and DIMMs, disengage the locking plungers, and swing the hinged
power supply out of the chassis. Or, you can remove the power supply entirely. However,
you need not remove the power supply for most routine service or upgrade tasks. As needed,
you may want to disconnect power supply cables to peripheral devices to swing the power
supply out fully.
See Chapter 2, “Servicing the System,” for complete details on removing the power supply.
To access components behind the power supply:
1. Unplug the AC power cord from the rear of the unit.
2. Remove the top cover and left side panel. See the previous section for details.
3. Grasp both knurled plungers on the power supply, pull them toward each other, and then
swing the power supply toward you.
Bottom plunger
Top plunger
NOTE Disconnect power cables to internal devices as needed to allow the power supply to swing out
fully.
4. Access the exposed components as needed.
To stow the power supply:
1. Reconnect any power cables that you disconnected.

8
2. Grasp both knurled plungers, pull them toward each other, and then swing the power
supply away from you, back into the chassis.
CAUTION Carefully swing the power supply back into the chassis. Avoid pinching cables. Hold the
external SCSI cable against the chassis brace or rearrange cables slightly while swinging the
power supply into the chassis.
3. Align the plunger holes and release both plungers.
4. Install the left side panel and top cover.
5. Plug the AC power cord into its connector on the rear of the chassis.
