Before You Begin

WARNING Disconnect the system and peripheral devices from AC power before servicing internal

components! Failure to remove AC power may result in equipment damage or
personal injury.

CAUTION Use an antistatic wrist strap for all servicing procedures to avoid the possibility of

electrostatic discharge.

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.

“Right side” and “left side” are as seen from the front of the unit.

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

You do not need any tools to open the TDZ 2000 GL2/ExtremeZ GL2 case.

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 system 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

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.

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.

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,

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.

4

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.

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. 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.

Before You Begin

WARNING Disconnect the system and peripheral devices from AC power before servicing internal

components! Failure to remove AC power may result in equipment damage or
personal injury.

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.

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.

See Chapter 1, “Accessing the System,” for instructions on opening the system, protecting
against electrostatic discharge, and closing the system. “Right side” and “left side” are as
seen from the front of the unit. Servicing procedures assume you have removed the left side
panel from the system.

Adding Memory

You can add system memory to the computer by adding or replacing Dual Inline Memory
Modules (DIMMs).

The system board features four DIMM sockets, which combined can hold up to 1 GB of
Synchronous Dynamic Random-Access Memory (SDRAM). See the system board diagram
in the System Board Manual for socket locations.

See Chapter 2, “Servicing the System,” to install a memory upgrade.

Precautions

To avoid damaging DIMMs and voiding the warranty, take the following precautions:

u

Do not touch the gold-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 must install DIMMs one at a time.

u

Install DIMMs one bank at a time; begin with bank 0 (nearest to the processor) or the
first open bank; end with bank 3.

u

Press the DIMM into the socket at a 90 degree angle, applying even pressure along the
top edge of the DIMM.

Memory Configurations

The following tables shows possible memory configurations. Each bank contains one socket.

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 processor retention module which surrounds the processor slots.
See the system board diagram in the TDZ 2000 GL2/ExtremeZ GL2 System Board Manual
for the location of processor slots and related connectors.

Single-to-Dual Upgrade

You can upgrade to dual processors by purchasing a TDZ 2000 GL2 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.

NOTE Since 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.

To install a single-to-dual processor upgrade:

1. Remove the air duct in accordance with instructions under replacing power supply

above.

2. Install a retention module, if necessary, onto the open processor slot. See Chapter 2,

“Servicing the System,” for details.

3. Install a heat-sink mounting bracket, if necessary, into place over the open processor

slot. See Chapter 2, “Servicing the System,” for details.

4. Orient the processor module so that the heat sink fins or cooling fan points toward the

DIMM sockets, and then insert the module into the open socket of the retention module.

5. Press straight down and apply even pressure at both ends of the CPU module until it

seats. The retention module is keyed to ensure proper insertion.

6. Press the processor module locking tabs outward until they click into the locked

position.

7. If you installed a boxed processor with integral fan into the secondary processor slot,

connect the fan power cable to the processor fan power connector on the system board.
If you installed a processor with a heat-sink, secure the heat-sink fins using a heat-sink

lock. See Chapter 2, “Servicing the System,” for details.

8. Replace the air duct you removed previously.

Adding Expansion Cards

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.

33

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

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

Non-PnP 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.

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 any
available ISA slot.

NOTE Assign system resources for any non-PnP 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. The bottom PCI slot shares space with the upper ISA slot. You can
install a card in the bottom PCI slot, or in the upper ISA slot, but not in both.

34

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 and remove the blanking plate for the slot. Keep the retaining

screw.

NOTE If you have no open slots and/or want to replace an existing expansion card, see the

instructions in Chapter 2, “Servicing the System.”

2. Remove the expansion card from its antistatic packaging.

3. Slide the expansion card carefully into the card guides. Ensure that the connectors on

the board’s edge are aligned properly with the slot connector.

4. Push the card into the slot firmly and evenly until it is fully seated in the slot connector.

5. Inspect the connection. If it does not appear to be correct, remove and reinstall the card.

6. Install the retaining screw.

7. Attach any required cables to the internal or external connectors.

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 System Setup for details on assigning system resources and configuring the BIOS for
expansion cards.

NOTE Treat non-compliant PCI cards and PCMCIA cards as ISA cards for assigning system

resources.

Adding Drives and Devices

The TDZ 2000 GL2/ExtremeZ GL2 features the following peripheral bays:

u

One 3.5-inch x 1.0-inch external bay for floppy disk drive.

35

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 optional devices.

u

Three 3.5-inch x 1.0-inch internal bays for system or optional disks.

Note the following restrictions on adding peripheral devices:

u

The bottom 5.25-inch bay (location 4) is not designed for CD drives.

u

Other than the CD-ROM drive, only one front-accessible EIDE device can be added.
This device must be installed in the bottom 5.25-inch bay (location 4).

u

The front-accessible bays are not designed to support hard disk drives.

u

A maximum of two EIDE, three 1.0-inch SCSI, or two 1.6-inch SCSI hard disk drives
are supported internally.

u

When installing 5.25-inch peripheral devices, use the screws provided in the package
found in the Accessory Box.

See the following for related information and important details:

u

The System Board Manual for details on SCSI connector locations and pinouts.

u

Chapter 5, “Peripherals,” for details on drive locations, jumpers, and cables.

36

u

Chapter 6, “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:

u

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
“Adding Expansion Cards” in this chapter for details.

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.

Location

Drive Peripheral Bay Max Bay Capacity

1 System disk drive Internal 3.5-inch x 1.6-inch
2 Add-on disk drive Internal 3.5-inch x 1.6-inch

See Chapter 2, “Servicing the System,” to install a memory upgrade.

37

Adding External SCSI Drives

You can add single-ended external SCSI drives to the system by connecting them to an
optional SCSI adapter. See “Adding Expansion Cards,” in this chapter for details on
installing an expansion card.

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:

Drives

1 to 4 6 meters 3 meters 3 meters 12 meters
5 to 7 6 meters 3 meters 1.5 meters 12 meters
8 to 15 N/A N/A N/A 12 meters

NOTE If longer Ultra SCSI cable lengths are required, Ultra SCSI mode can be disabled using

SYSUTIL, the Setup utility, or the on-board BIOS on the SCSI adapter. However, disabling
Ultra SCSI mode reduces the data transfer rate to 20 MB per second on Ultra Wide adapters
and to 10 MB per second on Ultra Narrow adapters.

SCSI-1 SCSI-2 Ultra LVD

38

NOTE The SCSI adapter counts as one device.

The total length of the SCSI cabling is the sum of the following:

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.

NOTE Make sure the last device on a chain of external SCSI devices has an active SCSI terminator

connected to the open SCSI port. All other external SCSI devices must have SCSI
termination disabled or removed.

SCSI ID Guidelines

By default, specific devices use the following SCSI IDs:

u

SCSI adapter (optional) uses ID 7

u

Read/write CD-ROM (optional) drive uses ID 4

u

Iomega Jaz 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 have 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

If your system has an optional SCSI adapter card installed, you can connect external SCSI

devices to the adapter’s external SCSI port.

NOTE The system BIOS will attempt to start the system using a hard disk drive connected to the

SCSI adapter in the lowest PCI slot. To start the system using an external SCSI hard disk

drive, you must ensure the drive’s SCSI adapter is installed lower in slot order than all other
bootable SCSI adapters

To add an external SCSI device:

1. Connect one end of the external SCSI cable to the external port of the SCSI adapter.

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.

39

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 Adapter or Device Settings

Depending on your system configuration or the capabilities of SCSI devices connected to
your system, you may need to change adapter or device settings. See the SCSI adapter
documentation delivered with the system for more information.

Cooling Fans

The TDZ 2000 GL2/ExtremeZ GL2 has two cooling fans. One is inside the power supply;
the other is mounted in the chassis. Both fans are 12 VDC. The fans pressurize the chassis
and force warm air out from the vents. Hardware controls the dynamic speed of each four­wire fan.

See the System Board Manual for connector locations and fan cable pinouts. See also

Chapter 2, “Servicing the System,” for details on replacing the chassis fans.
