Chapter 1
Setting Up
This chapter describes setting up the GLZ6 graphics tower, and assumes you
have already unpacked and begun setting up the workstation base unit.
Note: If you are upgrading an existing TDZ deskside workstation to a dual-
screen configuration, install the dual-screen upgrade. Refer to
Chapter 3, “Installing the Dual-Screen Upgrade.”
Installing the graphics tower involves unpacking the equipment, selecting the
installation location, and connecting the equipment. This chapter applies
only to single-screen and pre-configured dual-screen systems.
Unpacking the Equipment
Since you are reading this document, you have already opened the box and
unpacked at least some of the graphics tower equipment. Make sure you
have the following items before continuing. If anything is missing, call the
Intergraph Customer Response Center at 1-800-633-7248.
♦ Graphics tower
♦ Power cord (9.8 feet)
♦ Adapter cable (100-pin, 18 inches)
♦ VGA Loopback cable (15-pin, 32 inches)
♦ Footstands
♦ Diskette containing the Intergraph GL display driver
♦ Disposable antistatic wrist strap
Note: Documentation, parts, and an equipment list for the monitor should
be included with the monitor shipping package.
The GLZ6 graphics boards are already installed in the graphics tower and
workstation. The following figure shows how the boards are configured.

2Chapter 1 - Setting Up
Note: If you ordered the dual screen option pre-configured, additional
Rasterization Accelerator and Frame Buffer boards are installed in
the graphics tower, as shown by the dotted lines.

Selecting the Installation Location
After you unpack the equipment, select the installation location for the
graphics tower and workstation base unit (the GLZ6 system). When
selecting an installation location, consider the following:
♦ Because of the Adapter cable length, place the graphics tower on the
right side of the workstation (facing the back).
♦ The total weight of the GLZ6 system is approximately 120 pounds. If
you do not place the GLZ6 system on the floor, make sure the surface on
which it will rest can support the weight.
♦ Make sure the GLZ6 system has at least three inches of space in front
and behind for proper air ventilation. Never block the openings at the
front or back of the GLZ6 system.
♦ Avoid placing the GLZ6 system in locations with high levels of dust or
smoke.
♦ For a dual-screen configuration, two monitor orientations are possible -
horizontal (monitors side by side) or vertical (one monitor above the
other). Typically, the primary monitor is the left when horizontal, or the
top when vertical.
CAUTION
The surface on which you place the two monitors must be able to
support the combined weight of the monitors. If installing in a vertical
position, the support equipment for the top monitor must be specifically
designed for the purpose of stacking monitors.

4Chapter 1 - Setting Up
Connecting the Equipment
CAUTION
If the workstation is powered on, shut down and power off the
workstation before connecting the equipment. Leave the power cord
connected between workstation and the AC outlet or Uninterruptible
Power Source (UPS) to maintain ground.
Once you have selected a location and placed the equipment where you want
it, follow these instructions to connect the equipment. The following figure
shows all the ports for the cable connections stated in the following steps.
➤To connect the equipment:
1. Install the footstands on the bottom of the graphics tower.
2. Connect the Adapter cable to the adapter ports on the graphics tower
and the workstation.
3. Connect the monitor cable (or cables, if dual-screen) to the monitor(s)
and the graphics tower Video port.
4. Connect the VGA Loopback cable to the graphics tower VGA
Loopback port and the workstation VGA Loopback port.
CAUTION
Do not confuse the monitor cable (supplied with the monitor) with the
VGA Loopback cable (supplied with the graphics tower).
5. Connect the power cord to the graphics tower and to a grounded AC
outlet or (UPS).
6. Connect the power cord (supplied with the monitor) to the monitor
and a grounded AC outlet.

Chapter 2
Maintaining the System
This chapter describes opening the graphics tower to replace the
Rasterization Accelerator, Frame Buffer, and Expansion Adapter boards.
This chapter also describes opening the workstation base unit to replace the
Geometry Accelerator, Host Adapter, and VGA boards. Instructions for
troubleshooting the system and installing the GL display driver are also
included.
WARNING
AC filters, power supplies, and backplanes should always be serviced
by Intergraph field service personnel to guarantee safety.
Opening the Graphics Tower
Open the graphics tower when replacing the Geometry Accelerator board,
Frame Buffer board, or Expansion Adapter board. Use a quarter-inch
nutdriver to remove the screws mentioned in this section.
WARNING
Before opening the graphics tower, turn the workstation power off.
Leave the power cord connected between the graphics tower and the
AC outlet or UPS to maintain ground.
➤To open the graphics tower:
1. Remove the screw from the top cover as shown in the following
figure. Remove the top cover by sliding it back and up.

8Chapter 2 - Maintaining the System
2. If replacing the Expansion Adapter board, remove the footstands from
the graphics tower.
3. If replacing the Expansion Adapter board, remove the screw from the
top of the right side panel as shown in the following figure. Pull up
and out on the side panel to remove it from the graphics tower.

Avoiding Electrostatic Discharge
Some of the sensitive components inside the unit can be damaged by
electrostatic discharge. To avoid electrostatic discharge, take the following
precautions after opening the graphics tower.
♦ Discharge personal static charge by touching a bare metal surface in the
graphics tower.
♦ 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.
♦ Handle all printed circuit boards as little as possible and by the edges
only. Leave the boards in their protective packaging until instructed to
install them.
♦ Follow the instructions in the next section to attach an antistatic wrist
strap.
Attaching an Antistatic Wrist Strap
Use a disposable or reusable antistatic wrist strap when replacing boards in
the graphics tower.
Note: There is no increased risk of electrical shock when using a 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 the disposable wrist strap once, it cannot be used again.

10 Chapter 2 - Maintaining the System
➤To attach a reusable antistatic wrist strap:
1. Secure the metal clip to a bare metal surface that will keep the clip
from pulling away.
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.
Replacing Boards in the Graphics Tower
Follow the instructions in this section to replace the boards in the graphics
tower.
Rasterization Accelerator and Frame Buffer
The Rasterization Accelerator and Frame Buffer boards are joined by an
interface connector and six screws. Both boards must be replaced as a single
unit, referred to as the board set in these instructions.
CAUTION
The board set is extremely sensitive to static electricity. Do not open
the antistatic bag containing the board set until instructed to install it.
➤To remove the board set:
1. If your system is a dual-screen configuration, carefully remove the
clock sync cable as shown in the following figure.
2. Remove the screw securing the board set to the chassis. Refer to the
following figure.
3. Disconnect the board set from the backplane by raising the board
extractors. Refer to the following figure.
