1 Opening and Closing the Base Unit
This chapter describes avoiding electrostatic discharge, opening the TD-x20, TD-x25, TDZ-
x20, and TDZ-x25 workstation’s base unit, attaching an antistatic wrist strap, and closing
the base unit.
Avoiding Electrostatic Discharge
Some of the sensitive components inside the base unit can be damaged by static electricity.
To minimize this possibility, take the following precautions when working with the internal
components of the system to avoid electrostatic discharge.
u
To maintain ground, do not unplug the power cord from the base unit, AC outlet, or
UPS.
u
Touch the bare metal of the base unit to discharge any accumulated electrostatic charge.
u
Do not service the system on surfaces known to have high electrostatic buildup, such as
rugs and carpets. Work on a static-safe surface instead.
u
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.

u
After opening the base unit, attach an antistatic wrist strap as described in the next
section.
Opening the Base Unit
WARNING Before opening the base unit, turn the system power off. Use caution when removing
the top cover to avoid injury.
To open the base unit of a desktop system:
1. Pull the plunger out and rotate it to lock it in the open position. See the following
figure.

To open the base unit of a deskside system:
NOTE The left and right side panels are identified as if you are facing the front of the base unit.
1. Remove the footstands.
2. Remove the screw on the back of the top cover. Pull the top cover back an inch and lift
it off the base unit. Refer to the following figure.
3. Remove the two screws on the left side panel. Then pull the panel up and out to remove
it. Refer to the following figure.
4. If you are servicing the CD-ROM drive, floppy disk drive, or power supply, remove the
right side panel according to the procedure in step 3 above. Refer to the following
figure.

Attaching an Antistatic Wrist Strap
Use a disposable or reusable antistatic wrist strap when servicing or upgrading the
workstation.
NOTE There is no increased risk of electrical shock when using an antistatic wrist strap. If the wrist
strap does not snugly contact bare skin, static protection will not be effective.
To attach a disposable antistatic wrist strap:
1. Remove the wrist strap from the envelope.
2. Unfold the wrist strap and wrap the exposed adhesive side firmly around your bare wrist.
3. Peel the liner from the wrist strap copper foil. Attach the adhesive side of the copper
foil to a bare flat metal surface (electrical ground) inside the base unit.
NOTE After using a disposable wrist strap once, you cannot use it again.
To attach a reusable antistatic wrist strap:
1. Attach the wrist strap to the ground loop shown in the following figure.

2. Slip the elastic end of the wrist strap snugly around your bare wrist.
NOTE The metal conductor bead in the elastic must contact bare skin.
Closing the Base Unit
To close the base unit of a desktop system:
1. Remove the antistatic wrist strap from the ground loop inside the base unit.
2. Replace the top cover by aligning the tabs on the front of the top cover with the notches
behind the faceplate.
I/O Lock
Bracket
3. Lower the back of the top cover and slide it into place.
4. Turn the plunger to lock the top cover to the base unit.
To close the base unit of a deskside system:
1. Remove the antistatic wrist strap from the ground loop inside the base unit.
2. Replace the PCI access panel if removed.
3. Set the base unit in the upright position.
4. Replace the left or right side panel if removed.
5. Replace the top cover. Ensure the top cover is completely installed so the safety
interlock switch engages. If the cover is not properly installed, the system will not start.
6. Replace the footstands.
CAUTION After servicing or upgrading the system, always replace all panels and covers. The panels
and covers ensure the system maintains proper air flow, so internal components do not
overheat. Overheated components may fail prematurely and may be dangerous to touch.
The panels and covers also ensure electromagnetic interference (EMI) emissions are kept to
levels below the standard requirements.

2 Maintaining System Devices
This chapter describes cleaning the system and replacing system devices in the TD-x20,
TD-x25, TDZ-x20, and TDZ-x25 workstations.
Cleaning the System
Follow these guidelines for cleaning the system.
CAUTION Power off the system before cleaning the exterior surfaces, mouse, and keyboard. Do not
clean the CD-ROM drive.
Exterior Surfaces
Use a mild cleaning detergent and a clean cloth to clean the monitor screen and the exterior
surfaces of the base unit.
Mouse
9
On the bottom of the mouse, a retaining ring holds the tracking ball in place. To clean the
mouse, remove the retaining ring and turn the mouse over; the tracking ball will fall out.
Blow gently into the opening. Clean the tracking ball and rollers with a cotton swab and
alcohol. Replace the tracking ball and the retaining ring.
Keyboard
Dust the keyboard with a dry cloth. Aerosol cleaners are commercially available to remove
the dust between the keys of the keyboard. Never allow moisture on the keyboard or the
surface beneath the keys.
Replacing System Devices
This section describes replacing the following system devices:
u
Floppy disk drive
u
CD-ROM drive
u
Device in the optional device bay (desktop)
u
System hard disk drives
u
Auxiliary hard disk drives (deskside)
10
You will need the following tools to service the system:
u
Quarter-inch nutdriver
u
No. 1 Phillips screwdriver
u
No. 2 Phillips screwdriver
u
Three-sixteenth-inch nutdriver
u
Five-sixteenth-inch or 8 mm nutdriver
u
Small single-slot screwdriver
Open the base unit, take precautions against electrostatic discharge, and attach an antistatic
wrist strap as described in Chapter 1, “Opening and Closing the Base Unit,” before replacing
any parts. After replacing system parts, close the base unit as described in Chapter 1.
CAUTION The parts inside the base unit are designed to fit within very tight tolerances. Some force is
required to remove or insert parts. However, if you cannot remove or install a part properly,
ensure that there are no obstructions hindering the part.
NOTE “Right side” and “left side” are as seen from the front of the base unit.
Floppy Disk Drive

2. Remove the screws holding the drive to each side of the chassis, if necessary. Slide the
drive and its support bracket out of the base unit.
3. Remove the screws holding the drive to the support bracket, and then remove the drive
from the bracket.
To install a new floppy disk drive:
1. Mount the replacement drive to the support bracket using the screws removed
previously.
2. Install the drive and its support bracket into the base unit. In a deskside system, secure
the drive to the chassis using the screws removed previously, then connect the cables to
the device.
