Tools
You will need the following tools to service the system:
u
Antistatic wrist strap
u
Antistatic mat connected to an earth ground
u
Quarter-inch nutdriver
u
No. 1 and No. 2 Phillips screwdrivers
u
Small or medium flat-blade standard screwdriver
NOTE You do not need any tools to open the TDZ 2000 case.
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.
Protecting Against Electrostatic Discharge
Electrostatic discharge (ESD) can damage sensitive components inside the unit. Take the
following precautions when working with internal components:
u
Unplug the unit from AC power before servicing any electronic component inside the
chassis. Remember that the TDZ 2000 is always on when connected to AC power.
u
Touch the bare metal of the chassis to ensure the chassis and your body are at the same
electric potential.
u
Attach the antistatic wrist strap to its connector on the antistatic mat. Ensure that the
metal conductor bead in the elastic sleeve of the antistatic strap contacts bare skin.
u
Handle all printed circuit boards as little as possible and by the edges only.
u
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.
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.
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.
3
2. Grasp the lip on the top cover at the rear of the system and press up on the release. See
the following figure.
3. Keep pressing the release, slide the top cover back until it stops, remove it from the
chassis, and set it aside.
Press up on release located under lip
4
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 Component s Behind the Power Supply
To access the processors and DIMMs, remove the knurled retaining/grounding screw on the
rear of the chassis, 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. Remove the knurled retaining/grounding screw just below the top system fan on the rear
of the chassis.

Adding Memory
You can upgrade memory on the MSMT401 system board in 64 MB or 128 MB increments.
The minimum total memory is 64 MB and the maximum total memory is 512 MB.
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.
WARNING Disconnect the system from AC power before servicing internal components! Failure
to remove AC power may result in equipment damage or personal injury.
NOTE See Chapter 1, “Accessing the System,” for instructions on opening the system and
protecting against electrostatic discharge.
CAUTION Follow all warnings and cautions in 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 overtighten screws and other fasteners to avoid damaging threads.
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:
u
Do not touch the gold-plated finger contacts.
u
Do not install DIMMs that have tin-plated finger contacts.
u
Do not bend, twist, drop, or otherwise handle DIMMs carelessly.
u
Do not expose DIMMs to moisture or extreme temperatures.
u
Do not remove DIMMs from the antistatic bag until installation.
Before you install memory, do the following:
u
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.
u
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:
u
Remember that you can install DIMMs one at a time.
u
Install DIMMs one bank at a time; begin with bank 0 or the first open bank; end with
bank 3.
u
Press the DIMM straight down into the socket. Do not rock the DIMM; apply even
pressure along the top edge of the DIMM.
u
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.
NP designates the socket is not populated.

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.
36
Adding a Processor
You can upgrade a single processor system to a dual processor system. You can upgrade a
processor to a faster processor. You can install a processor module with heat sinks
(CICM452, Intergraph standard part) or a boxed processor module with integral fan (nonIntergraph part). The lower right heat sink fin on the Intergraph processor module is
removed to provide clearance for the fan connector at J5 on the MSMT401 Revision A
system board.
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 in the following ways:
u
You can purchase a TDZ 2000 single-to-dual processor upgrade kit (PUPG11906) from
Intergraph Computer Systems. The kit contains all the hardware, software, and
documentation required to perform the upgrade.
u
If you purchase a second processor from another vendor, you can purchase a Voltage
Regulator Module (VRM) from Intergraph Computer Systems.
After completing the hardware upgrade, you must also upgrade to a multi-processor version
of Windows NT. You can upgrade the operating system in the following ways:
u
You can purchase the Intergraph upgrade kit mentioned previously. The kit contains all
the hardware, software, and documentation required to perform the upgrade.
u
If you have or purchase a Windows NT 4.0 Workstation Resource Kit (ISBN 1-57231343-9), you can use software on the kit’s CD-ROM to upgrade Windows NT 4.0. The
files required for the upgrade are
u
While not recommended by Intergraph Computer Systems, you can back up all critical
UPTOMP.EXE , UPTOMP.INF, and UPTOMP.TXT.
system data, install the second processor and VRM, and reinstall Windows NT 4.0 to
load the required multi-processor Hardware Abstraction Layer (HAL).
NOTE You do not have to change any jumper settings when installing a second processor.
To install a single-to-dual processor upgrade:
1. Swing the power supply out to expose the processor slots. See Chapter 1, “Accessing
the System,” for details.
2. Remove the MSMT379 bus termination card from J8, the secondary processor slot.
Place the card in an antistatic package.
3. Orient the processor module so that the heat sink fins point to the top of the chassis and
insert the module into the open socket on the dual processor retention module (DPRM).
4. Press straight down and apply even pressure at both ends of the CPU module until it
seats. The DPRM is keyed to ensure proper insertion.
5. Press the processor module locking tabs outward until they click into the locked
position.
6. Find J10, the secondary voltage regulator module (VRM) socket.
7. Remove the new VRM from its antistatic package and slide the VRM into its mount.
8. Press straight down and apply even pressure at both ends of the VRM until it snaps into
place. The socket is keyed to ensure proper insertion.
9. If you installed a boxed processor with integral fan into the secondary processor slot,
connect the fan cable to J1, located near the top, right corner of the system board. The
fan cable for a boxed processor installed in the primary processor slot connects to J4,
located near the top left of the system board.
10. Swing the power supply back into the chassis and secure it with the plungers.
Adding Expansion Cards
37
You can install 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.
u
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.
NOTE All PCI expansion cards sold by Intergraph fully comply with the
Interconnect Specification, 2.1.
u
Non-compliant PCI cards mechanically comply with the 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.
u
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.
Peripheral Component
38
u
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.
NOTE Assign 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. Slots 1 through 4 are primary slots and slots 5 through 7 are secondary.
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.
Slot 0 - AGP
Slot 1 - PCI
Slot 2 - PCI
Slot 3 - PCI
Slot 4 - PCI
Slot 5 - PCI
Slot 6 - PCI
Slot 7 - PCI (shared)
Slot 7 - ISA (shared)
NOTE Since 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.

Installing Expansion Cards
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.
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 “Configuring the BIOS” chapter in the TDZ 2000 System Setup for details on
assigning system resources and configuring the BIOS for expansion cards.
See also the “Using System Resources” chapter in the TDZ 2000 System Setup, for a list of
available system address resources (DMA, I/O, memory) and related details.
NOTE Treat non-compliant PCI cards and PCMCIA cards as ISA cards for assigning system
resources.
Adding Internal SCSI Drives
The system provides dual-channel Wide Ultra SCSI-3 support for internal and external mass
storage devices.
The TDZ 2000 features the following peripheral bays:
u
One 3.5-inch x 1-inch external bay for floppy or combo drive.
u
One 5.25-inch x 1.6-inch external bay for CD-ROM.
u
Two 5.25-inch x 1.6-inch external bays for disk drives or other devices.
u
Three 3.5-inch x 1-inch or two 3.5-inch x 1.6-inch internal bays for system or optional
disks.
NOTE When installing 5.25-inch peripheral devices, use the screws provided in the package found
in the Accessory Box.

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.
u
If you are installing a drive that connects to an adapter card (such as an EIDE drive), see
the vendor’s documentation for installing the adapter card and required cables. See the
“Adding Expansion Cards” section above for details.
u
If you are installing a Kingston or other brand of removable disk drive module, see the
vendor’s documentation for installing the module, removing terminators, and setting the
SCSI ID.
NOTE Internal 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
following table provides the drive locations and related information. See the figure below.

10. Install the right cover.
11. Connect the SCSI cable and the power cable to the new drive.
Adding External SCSI Drives
You can add single-ended external SCSI drives to the system by connecting them to a SCSI
port on the back of the system. The TDZ 2000 features a standard Ultra SCSI external port.
A Wide Ultra SCSI external port is optional. See “External Ports” in Chapter 5, “System
Board,” for a figure of port locations.
You can also install additional SCSI expansion cards (adapters) to support external SCSI
drives. See the “Adding Expansion Cards” above for details.
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.
SCSI Cable Length Guidelines
The number of drives and length of the cables used to connect the drives is a factor when
using SCSI-1, Fast SCSI (SCSI-2), Ultra SCSI, and Wide Ultra SCSI drives. Fast SCSI,
Ultra SCSI, and Wide Ultra SCSI impose shorter cable restrictions than SCSI-1. The total
length of the SCSI cabling must not exceed the following:
47
Drives
1 to 4 19.8 ft
5 to 7 9.9 ft
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:
u
Wide Ultra SCSI cable inside the system—52 inches (132 cm)
u
Ultra SCSI cable inside the system—14 inches (35.5 cm)
u
SCSI cable inside each device—average 8 inches (20 cm)
u
SCSI cable between the system and the first device
u
SCSI cable between each device
SCSI Cable Quality Guidelines
To ensure data integrity and optimum performance, do the following:
u
Use only Intergraph SCSI cables. Cables from other vendors may not provide adequate
shielding.
u
Use the shortest cables possible to connect SCSI devices to the system and to each other.
SCSI ID Guidelines
By default, specific devices use the following SCSI IDs:
u
System disk drive (standard) uses ID 0
u
SCSI bus always uses ID 7
u
Read/write CD-ROM (optional) drive uses ID 4
u
4 mm DAT drive (optional) uses ID 6
u
Iomega Jaz drive (optional) uses ID 6
48
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:
u
Enable termination on the last external drive on the SCSI cable chain.
u
Disable termination on all other external drives on the SCSI cable chain.
u
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 standard Ultra SCSI port, located just under the AC line out connector
−
The optional Wide Ultra SCSI port, located on the right side of the I/O panel
2. Connect the other end of the cable to the SCSI device.
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 A d apter 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 Chapter 3, “Configuring the System,” in the TDZ 2000 System Setup for
details.

PCI to ISA Bus In terrupt 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:
Interrupt Line
INTA PIRQ0 PIRQ1 PIRQ2 PIRQ3 PIRQ0 PIRQ1 PIRQ2
INTB PIRQ1 PIRQ2 PIRQ3 PIRQ0 PIRQ1 PIRQ2 PIRQ3

You can assign the spare interrupt listed above to an ISA device. When you add a PCI
device to the system, the system BIOS automatically assigns the interrupt. However, at least
one interrupt must be available for the PCI bus.
When you add an ISA board, you must reserve the interrupt using the AMIBIOS Setup
utility and jumpers on the expansion board. See the TDZ 2000 System Setup for details on
using AMIBIOS Setup. See also the vendor documentation for the expansion board for
jumper and related information.

Power Supply
CPWS15200 is a 500-watt autoranging supply. It switches between 90-132 VAC or 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, even though the fans do not run and the LEDs do not glow. In this respect, the
TDZ 2000 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.

Cooling Fans
The TDZ 2000 has three cooling fans. One is inside the power supply; the others are
mounted in the chassis. All fans are 12 VDC. The fans pressurize the chassis and force
warm air out from the vents. Hardware controls the dynamic speed of each four-wire fan.
See Chapter 5, “System Board,” for connector locations and fan cable pinouts. See also
Chapter 2, “Servicing the System,” for details on replacing the chassis fans.
The table below summarizes fan information.

The two chassis fans (CFAN12009) are field replaceable.
The power supply fan is not field replaceable. If the fan requires replacement, you must
replace the power supply.
Arrows on each fan indicate airflow direction and rotation, as in the following illustration.

Ensure that you install each chassis fan with the airflow direction arrow pointing toward the
inside of the chassis.

Dynamic Fan Speed Control
Hardware controls dynamic fan speed, based on temperature measured by a sensor and
whether the temperature is rising or falling. See “Temperature Sensors” below for additional
details.
The following table indicates the composite fan speed for four temperature setpoints. As the
temperature inside the chassis varies with the heat load, the fans change speed accordingly.
For example, if the temperature exceeds setpoint T1, composite fan speed increases to
medium low.
Temperature

T3—109.4° F (43° C)
T2—104° F (40° C)
T1—98.6° F (37° C)
