CAUTION
CAUTION
Tools
“Right side” and “left side” are as seen from the front of the unit.
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.
Use an antistatic wrist strap for all servicing procedures to avoid the possibility of electrostatic
discharge.
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.
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.
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.
WARNINGDo 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
NOTE
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.
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

Before You Begin
WARNINGDisconnect the system from AC power before servicing internal components! Failure to
remove AC power may result in equipment damage or personal injury.
NOTE
CAUTION
CAUTION
CAUTION
See Chapter 1, “Accessing the System,” for instructions on opening the system and protecting
against electrostatic discharge.
Follow all warnings and cautions in servicing instructions. If you fail to follow documented,
approved procedures, personal injury and damage to equipment can result.
Use an antistatic wrist strap for all servicing procedures to avoid the possibility of electrostatic
discharge.
Do not overtighten screws and other fasteners to avoid damaging threads.
Adding Memory
You can upgrade memory on the MSMT589 system board in 64 MB, 128 MB, or 256 MB
increments. The minimum total memory is 64 MB and the maximum total memory using 256
MB DIMMs is 1.5 GB.
You can install DIMMs one at a time. Each bank has only one slot.
Memory upgrade kits from Intergraph Computer Systems contain one DIMM and a disposable
antistatic wrist strap.
CAUTION
System memory modules from Intergraph Computer Systems are certified for use with
Intergraph computers at extremes of temperature and system load to ensure reliable
performance. System memory modules available from other vendors may not function
properly or reliably in your Intergraph computer.
To avoid damaging DIMMs and voiding the warranty, take the following precautions:
Do not touch the gold-plated finger contacts.
Do not install DIMMs that have tin-plated finger contacts.
Do not bend, twist, drop, or otherwise handle DIMMs carelessly.
Do not expose DIMMs to moisture or extreme temperatures.
Do not remove DIMMs from the antistatic bag until installation.
Before you install memory, do the following:
Inspect DIMM keying. The finger contacts on the DIMM must match the socket
configuration. This ensures that you have the correct voltage and type of DIMM.
Inspect DIMM contacts. The DIMM must have gold-plated fingers that match the goldplated socket contacts.
Follow these population rules to correctly install the DIMMs:
The system board features two memory controllers. DIMM banks 0, 2, and 4 are
maintained by the primary memory controller; banks 1, 3, and 5 are maintained by the
secondary memory controller.
If you are installing both unbuffered and registered DIMMs, you must install the
unbuffered DIMMs in banks 0, 2, 4 or banks 1, 3, 5, and the registered DIMMs in banks
1, 3, 5 or banks 0, 2, 4, respectively.
For best performance, populate both memory controllers equally when an even number of
DIMMs are used. For example, if two DIMMs are used, install them into Bank 0 and
Bank 1.
Remember that you can install DIMMs one at a time.
Press the DIMM straight down into the socket. Do not rock the DIMM; apply even
pressure along the top edge of the DIMM.
33
Restart the computer after adding or replacing DIMMs. The computer detects the new
memory automatically.
The following table shows possible memory configurations. Each bank contains one socket.
See the system board diagram in Chapter 5, “System Board,” for socket locations.
To install the memory upgrade:
1. Swing the power supply out to expose the DIMM sockets. See Chapter 1, “Accessing the
System,” for details.
2. Locate the available DIMM socket and ensure the release tabs are open.
3. Grasp the DIMM so that the notch positions match the keys in the socket. See the figure
in the section, “DIMMs,” in Chapter 2, “Servicing the System.”.
4. Insert the DIMM straight down into the socket.
5. Push gently straight down until the release tabs snap into place.
6. Swing the power supply back into the chassis and secure it with the plungers.

Adding a Processor
You can upgrade a single processor system to a dual processor system. You can upgrade a
processor to a faster processor.
Processors are mounted in a dual processor retention module (DPRM), which surrounds the
processor slots. See the system board diagram in Chapter 5, “System Board,” for the location
of processor slots and related connectors.
Single-to-Dual Upgrade
You can upgrade to dual processors by purchasing a TDZ 2000 GT1 single-to-dual processor
upgrade kit from Intergraph Computer Systems. The kit contains all the hardware, software,
and documentation required to perform the upgrade.
After installing a second processor, you must reinstall Windows NT on the system to ensure
proper operation with multiple processors.
35
NOTESince the second processor should be the same speed as the first, you do not have to change
any processor frequency jumper settings when installing a second processor.
Adding Expansion Cards
You can install Accelerated Graphics Port (AGP), Peripheral Component Interconnect (PCI),
non-compliant PCI, Industry Standard Architecture (ISA), and Plug-n-Play (PnP) expansion
cards in the system. See below for a general description of the types of cards.
PCI cards contain configuration registers that define resource information to the system
during startup. PCI cards do not require manual system configuration when installing the
card. The system BIOS detects the board’s presence during startup and reads information
from the board’s configuration registers to assign the necessary system resources.
NOTEAll PCI expansion cards sold by Intergraph fully comply with the
Interconnect Specification, 2.1.
Non-compliant PCI cards mechanically comply with the Peripheral Component
Peripheral Component
Interconnect Specification 2.1, but do not contain configuration registers that allow the
system to automatically assign the necessary resources. These cards install in PCI slots,
but you must configure the BIOS to assign system resources before installing the card. In
this regard, they are like ISA cards, as described below.
ISA cards do not contain registers that define the resource information to the system
during startup. Therefore, you must configure the BIOS to define the card to the system
before installing the ISA card. This reserves system resources for the card.
PnP cards are ISA cards that contain configuration registers like PCI cards. During
startup, the system BIOS automatically detects the installed card and assigns the
necessary system resources. Since a PnP card is ISA-based, you install it in the ISA slot.
NOTEAssign system resources for an ISA card and any non-compliant PCI cards before installation.
See the “Assigning System Resources” section below.
Each installed PCI card must draw less than 25 watts of power. The total allowable maximum
wattage for PCI cards is 175 watts. The PCI slots are limited to 25 watts power dissipation
per the Peripheral Component Interconnect Specification 2.1.
Slot Locations
The expansion slots are located at the bottom, left section of the system board, as shown in the
following figure. PCI slots 1 through 3 are on a primary PCI bus connected to the primary LE
chipset. PCI slots 4 through 7 are on a primary PCI bus connected to the secondary LE
chipset. Slot 7 is a shared PCI/ISA slot. You can install a card in the number 7 PCI slot or
the ISA slot, but not both.
NOTESince the TowerMate expansion base uses the ISA slot to connect to the Ultra-tower, you
cannot install a card into either of the shared slots if you install the TowerMate option.
However, the TowerMate features a shared PCI/ISA slot, which replaces the occupied shared
slot in the Ultra-tower. For more information, see the TowerMate documentation.
Upgrading Graphics Cards
If you are upgrading or replacing an Intergraph graphics, geometry, or VGA/power supply
card, see the following tables for part numbers and recommended PCI slot designations.
Intergraph Graphics Card Part Numbers
The table below lists the part numbers of Intergraph graphics cards specified in the PCI Slot

Expansion Slot Designations for Graphics Cards
DS, TS, and QS indicate dual-screen, triple-screen, and quad-screen configurations,
respectively.
If you are installing double card sets, such as a graphics card and a geometry accelerator,
repeat the following procedure for the second card. See the documentation that came with the
card for details on connecting the two cards.
For other cards, such as internal modems or SCSI adapters, see the documentation that came
with the card for details on installation, configuration, cable connections, and operation.
To install an expansion card:
1. Locate an open slot. If you are installing any of the Intergraph RealiZm II products, see
the table above for required slot assignments.
2. Remove the blanking plate for the slot. Keep the retaining screw.
3. Remove the expansion card from its antistatic packaging.
4. Slide the expansion card carefully into the card guides. Ensure that the gold-fingered
connectors on the board’s edge are aligned properly with the slot connector.
5. Push the card into the slot firmly and evenly until it is fully seated in the slot connector.
6. Inspect the connection. If it does not appear to be correct, remove and reinstall the card.
7. Install the retaining screw.
8. Attach any required cables to the internal or external connectors.
9. Install covers and restart the system.
Expansion Cards with PCI-to-PCI Bridges
If you add an expansion card with a PCI-to-PCI bridge to the system, you may encounter boot
problems. This happens because such a card essentially adds another PCI bus to the system,
and causes a renumbering of the PCI buses in the system. For example, if you add such a card
to an expansion slot on PCI bus 0:
PCI bus 0 remains PCI bus 0
The card becomes PCI bus 1
PCI bus 1 becomes PCI bus 2
You must change the boot order in the SCSI Configuration Utility for the SCSI controllers on
the PCI buses to reflect the new PCI bus numbering. See System Setup for information on
running and using the SCSI Configuration Utility.
However, Windows NT will not use the boot order set by the SCSI Configuration Utility.
Windows NT always finds PCI bus 0 first. Ensure that your system’s primary boot device is
on PCI bus 0, and then use the SCSI Configuration Utility as needed to change boot order.
Assigning System Resources
Some expansion cards include a configuration diskette that you can use to reserve the system
resources required for the card. Other expansion cards do not include a diskette, but require
that you manually program the BIOS with the configuration information.
See the System Setup for details on assigning system resources and configuring the BIOS for
expansion cards, a list of available system address resources (DMA, I/O, memory), and related
details.
39
NOTE
Treat non-compliant PCI cards and PCMCIA cards as ISA cards for assigning system
resources.
Adding Internal SCSI Drives
The system features integrated Narrow Ultra SCSI and Wide Ultra2 SCSI adapters, both with
internal and external ports, to support internal and external mass storage devices.
The TDZ 2000 GT1 features the following peripheral bays:
One 3.5-inch x 1.0-inch external bay for floppy or combo drive.
One 5.25-inch x 1.6-inch external bay for CD-ROM.
Two 5.25-inch x 1.6-inch external bays for disk drives or other devices.
Three 3.5-inch x 1.0-inch or two 3.5-inch x 1.6-inch internal bays for system or optional
disks.
See the following chapters for related information and important details:
Chapter 5, “System Board,” for details on SCSI connector locations and pinouts.
Chapter 6, “Peripherals,” for details on drive locations, jumpers, and cables.
Chapter 7, “Power Supply and Cooling Fans,” for details on power supply cable
connectors and pinouts.
Remember the following when installing devices in the system’s drive bays:
If you are installing a SCSI drive, have the vendor’s documentation available to follow
instructions for setting the SCSI ID, enabling or disabling termination, installing device
drivers when required, and configuring other drive attributes.
40
If you are installing a drive that connects to an adapter card, see the vendor’s
documentation for installing the adapter card and required cables. See the “Adding
Expansion Cards” section above for details.
If you are installing a removable disk drive module, see the vendor’s documentation for
installing the module, removing terminators, and setting the SCSI ID.
NOTEInternal SCSI drives are not terminated. The internal SCSI cable provides termination. You
must disable termination on any drive that you install in the system.
Device Locations
You can add optional mass storage devices to the internal and external drive bays. The

Adding External SCSI Drives
You can add Low Voltage Differential (LVD) signaling and single-ended external Narrow
Ultra SCSI drives to the system by connecting them to a SCSI port on the back of the system.
The TDZ 2000 GT1 features integrated Narrow Ultra SCSI and Wide Ultra2 SCSI adapters,
both with internal and external ports. See “External Ports” in Chapter 5, “System Board,” for
a figure of port locations.
NOTE
Most SCSI adapters do not recognize a hard disk drive that was formatted using a different
brand of adapter. For example, a hard disk drive formatted with an Adaptec SCSI adapter will
not work with a Symbios SCSI adapter. You must use only Symbios-formatted hard disk
drives with a Symbios SCSI adapter.
46
SCSI Cable Length Guidelines
The number of drives and length of the cables used to connect the drives is a factor when
using SCSI-2, and Ultra SCSI drives. SCSI-2 and Ultra SCSI impose shorter cable
restrictions than SCSI-1. The total length of the SCSI cabling must not exceed the following:
Drives
SCSI-1SCSI-2Ultra SCSIWide Ultra2 (LVD) SCSI
1 to 46 meters3 meters3 meters12 meters
5 to 76 meters3 meters1.5 meters12 meters
8 to 15N/AN/AN/A12 meters
NOTE
The SCSI controller (on the system board or an adapter card) counts as one device.
The total length of the SCSI cabling is the sum of the following:
Ultra SCSI cable inside the system—14 inches (35.5 cm)
SCSI cable inside each device—average 8 inches (20 cm)
SCSI cable between the system and the first device
SCSI cable between each device
SCSI Cable Quality Guidelines
To ensure data integrity and optimum performance, do the following:
Use only Intergraph SCSI cables. Cables from other vendors may not provide adequate
shielding.
Use the shortest cables possible to connect SCSI devices to the system and to each other.
CAUTION
You should try to minimize cable flexing during handling. SCSI cables should not have any
creased bends. Take care when installing or replacing cables to insure that they do not
contact sharp metal surfaces or become excessively bent or twisted.
SCSI ID Guidelines
By default, specific devices use the following SCSI IDs:
System disk drive (standard) uses ID 0
SCSI bus always uses ID 7
4 mm DAT drive (optional) uses ID 6
NOTE
To easily determine the ID of each SCSI device on the system, restart the system. When the
BIOS screen displays, look for the list of SCSI devices and write down the ID for each device.
Some SCSI devices feature push switches to set the ID, while others have DIP switches or
jumpers. See the vendor documentation for details on setting the ID.
SCSI Termination Guidelines for External Devices
Follow the guidelines below for terminating SCSI devices:
Enable termination on the last external drive on the SCSI cable chain.
Disable termination on all other external drives on the SCSI cable chain.
Use only an active terminator on externally-terminated devices.
Connecting the Device
To add an external SCSI device:
1. Connect one end of the external SCSI cable to one of the following external ports:
− The integrated Narrow Ultra SCSI port
− The integrated Wide Ultra2 SCSI port
2. Connect the other end of the cable to the SCSI device.
47
3. Set the SCSI ID of the device to an unused number.
4. If the SCSI device is:
− the last or only device on the SCSI chain, enable SCSI termination
− NOT the last or only device on the SCSI chain, disable SCSI termination
5. Ensure that the power switch on the device is in the off position, and then connect the
power cord to the device and then to an AC receptacle.
6. Turn on the power to the device and any other devices on the SCSI chain.
7. Start the system. If necessary, install the software drivers and configure the drive
according to the vendor’s instructions.
Changing SCSI Host Adapter or Device Settings
Depending on your system configuration or the capabilities of SCSI devices connected to your
system, you may need to use the SCSI Configuration Utility to change host adapter or device
settings. See the System Setup for details.

OffVery little power consumption. System is Off but can
be turned on manually by pressing the power button or
remotely using the Wake-on-LAN feature.
OffPhysical OffOffNo power consumption. The system is disconnected
from AC line power, or is indicating that one of the
supply voltages is not correct. The system requires
reconnection of power or correction of voltage problem
and returns to the Working state only after a full
shutdown and restart.
If the power cord is plugged in, but the LED is off, then the system has a power voltage
problem. Call the Customer Response Center for assistance.
58
Intrusion Alert Switch
The intrusion alert switch (CSWX308) is mounted at the top left side of the system near the
front. This microswitch is the only replaceable component in the hardware monitoring system.
If you detach the side panel when the system is off, the event is registered in the InterSite
Hardware Monitor software. See Chapter 2, “Servicing the System,” for details on replacing
the switch. See also InterSite Hardware Monitor Help for details.
Temperature Sensors
Resistive temperature sensors are located on the system board near the primary processor and
the expansion slots, respectively. These devices provide signals for reporting temperature
readout data to the InterSite Hardware Monitor software. The sensor at the expansion slots
provides the signal for controlling fan speed. The temperature sensors are part of the system
board and are not field replaceable. See the system board diagram in Chapter 5, “System
Board,” for sensor location.

The Ensoniq ES1371 AudioPCI sound processor is configured entirely through I/O port
accesses. When the system is powered up, the hardware forces the Ensoniq ES1371 to
respond to default I/O port addresses, interrupt request (IRQ) level, and direct memory access
(DMA) request and acknowledge. The following table shows the default sound processor
configurations and available programmable settings.

PCI to ISA Bus Interrupt Mapping
The ISA bridge provides the sixteen conventional ISA interrupts, plus four interrupt request
pins for PCI peripheral interrupts (PIRQ0 through PIRQ3). For PC-AT architecture
compatibility reasons, the PCI interrupts are routed to the ISA interrupts within the ISA
bridge. The assertion of a PCI interrupt concludes in an ISA interrupt being asserted.
Bit 7 of each PIRQ registers enable (Low) or disable (High) the routing of the PIRQ to an ISA
interrupt. The lowest four bits (3:0) of each PIRQ register determines to which ISA interrupt
the PIRQ is routed. You can map the PIRQs to the following ISA interrupts:
IRQ 5, 10, 11, 15
You can also map to IRQ 3, 4, 7, 12, and 14, but other devices are disabled if you do so.
Each PCI slot has four available interrupt lines: INTA, INTB, INTC, and INTD. These are
connected to the PCI interrupts, PIRQ0 through PIRQ3, as shown below:

Peripheral Cables
This section provides information on peripheral cables and associated connections. See the
section, “Cable Routing and Pinouts,” in Chapter 5, “System Board,” for additional details.
Cable illustrations are not to scale. You can identify the cables and connectors using their
spacing as reference. Connectors for SCSI devices are spaced approximately 8 in (20 cm)
apart.
CAUTION
CAUTION
You should try to minimize cable flexing during handling. SCSI cables should not have any
creased bends. Take care when installing or replacing cables to insure that they do not
contact sharp metal surfaces or become excessively bent or twisted.
You must disable termination on any SCSI device you install internally. If you do not disable
termination, the system may fail to start or may behave erratically.

CPWS152 is a 500-watt Power Factor Corrected (PFC) autoranging supply. It automatically
switches between the 115V range (90-132 VAC) and 230V range (180-264 VAC), depending
on the location. The input frequency is 47-63 Hz, single phase. At full load, the power supply
has a minimum efficiency of 65 percent.
When you connect AC power to the system, the computer is powered in its lowest “trickle”
power state (the 5V Standby output is On) and the Power LED glows yellow, though the fans
do not run. In this respect, the TDZ 2000 GT1 is always powered on.
An interlock switch turns off input voltage to the power supply when the side panel is
removed. A tab on the left end of the left side panel closes the switch when the panel is
correctly installed on the system.
The power supply contains no user- or field-serviceable parts. You must install a new power
supply if an internal component, such as the fan or interlock switch, is defective.
The following table details the DC output specifications for the power supply.
