documented 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.

“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

Quarter-inch nutdriver

u

No. 1 and No. 2 Phillips screwdrivers

u

Three-sixteenth-inch or 5 mm nutdriver

u

Five-sixteenth-inch or 8 mm nutdriver

u

Small single-slot screwdriver

Avoiding Electrostatic Discharge

Sensitive components inside the base unit can be damaged by static electricity. To protect
against this possibility, take the following precautions when working with internal
components.

u

Unplug the unit from AC power before servicing any electronic component inside the
chassis.

u

Touch the bare metal of the base unit to ensure the base unit and your body are at the
same electric potential.

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

Use a disposable or reusable antistatic wrist strap when servicing or upgrading the system.
Once a disposable wrist strap is used, it cannot be used again.

u

Attach an antistatic wrist strap to any bare metal part of the base unit. The metal
conductor in the elastic sleeve of reusable antistatic straps must contact bare skin.

Opening the Base Unit

WARNING Before you open the base unit, shut down the system and turn off power to the system

and external devices (including peripheral devices and the monitor). Use caution to
avoid injury when removing covers and other hardware.

CAUTION Ensure the front and side stabilizers of the rack in which the system is mounted are fully

extended.

To open the base unit:

1. Remove the screws that secure the handles to the rack.

2. Disconnect all cables including the power cable, monitor, and all peripheral cables from

the back of the unit.

3. Slide the base unit out of the rack until it locks in the extended position.

4. Remove and retain the two screws that secure the cover to the chassis: one each on the

upper left and upper right corners of the back of the chassis.

one being replaced.

16

NOTE If the system uses the optional Mylex RAID controller, the jumper connectors JP2 and JP3

must not have any jumpers installed.

9. If the old disk drive bay has a SAF-TE card (as described in the next section), remove it

from the old disk drive bay and install it in the same location on the new disk drive bay.

10. Insert the new disk drive bay partially into the chassis.

11. Reconnect the SCSI cable and power connectors in the same positions as the old disk

drive bay.

12. Insert the new disk drive bay the rest of the way into the chassis, and secure it with the

screws removed earlier.

13. Insert the disk drives into the slots in the disk drive bay. The drives should be installed in

the same slots from which they were removed.

14. Replace the front panel and cover.

15. Restart the system and ensure the LED for each drive lights and remains steady green. If

not, refer to the System Setup for status LED information.

SAF-TE Card

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.

WARNING Follow all warnings and cautions in the servicing instructions. If you fail to follow

documented procedures, personal injury and damage to equipment can result.

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

electrostatic discharge.

CAUTION Do not overtighten screws and other fasteners to avoid damaging threads.

CAUTION Follow all warnings and cautions in these upgrade instructions. If you fail to follow

documented, approved procedures, personal injury or damage to equipment can result.

See Chapter 1, “Accessing the Components,” for details on opening the system and protecting
against electrostatic discharge. These procedures assume you have removed the cover from
the system. “Right side” and “left side” are as seen from the front of the unit. After upgrading
the system, replace panels as described in Chapter 1, “Accessing the Components.”

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).

CAUTION System memory modules from Intergraph Computer Systems are certified for use with

Intergraph computers at extremes of temperatures 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 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 slot keys on the DIMM must match the slot keys in the
DIMM socket. 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 DIMMs:

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

Do not mix registered and unbuffered DIMMs.

u

Do not mix ECC and non-ECC DIMMs.

NOTE Whenever you change your memory type, either from ECC to non-ECC or the reverse, you

should verify that the DRAM Type BIOS parameter is set correctly. For more information, see

System Setup

.

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

See Chapter 2, “Servicing the System,” for instructions to install a DIMM. See the System
Board Manual for DIMM socket locations.

32

Upgrading Processors

When higher-speed processors become available, you can upgrade the existing processors to
faster processors.

Processors are mounted in a processor retention module which surrounds the processor slots.

See Chapter 2, “Servicing the System,” for information on replacing the processors. See the
System Board Manual for the location of processor slots and related connectors.

You can upgrade processors by purchasing a processor upgrade kit from Intergraph Computer
Systems. The kit contains all the hardware, software, and documentation required to perform
the upgrade.

After installing faster processors, you must reinstall Windows NT on the system to ensure
proper operation with the new processors.

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.

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

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.

Peripheral Component

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

See the System Board Manual for the location of the expansion slots on the system board.

One PCI slot shares space with one ISA slot. You can install a card in the shared PCI slot, or
in the shared ISA slot, but not in both.

AGP slot

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.

34

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 when assigning system

resources.

Adding Disk Drives to the Disk Drive Bay

The system supports up to four 3.5-inch JBOD (for “just a bunch of disks”) or RAID SCA
SCSI disk drives in the disk drive bay. The type of disk drive you can install depends on the
configuration of your system.

JBOD disk drives are controlled by a plug-in dual-channel Low Voltage Differential Signaling
(LVDS) SCSI controller. RAID capability is provided by an optional single-channel Mylex
RAID controller and an optional SCSI Activity Fault-Tolerant Enclosure (SAF-TE) card
connected to the backplane of the disk drive bay. The SCSI address of the disk drives in the
disk drive bay are assigned by the disk drive bay backplane.

CAUTION Only use disk drives purchased from Intergraph in the disk drive bay. This ensures the drives

meet the disk drive bay specifications.

See Chapter 2, “Servicing the System,” or System Setup for information on installing JBOD or
RAID disk drives in the disk drive bay.

Adding an Internal Peripheral Device

The CD-ROM drive, floppy disk drive, and system drive are standard, and are already
installed in the peripheral device bay. You can add an optional EIDE or SCSI peripheral
device to the available peripheral device bay.

The following describes the devices in the peripheral device bay.

35

Drive

Type Maximum Bay Capacity

SCSI System disk drive Internal only 5.25-inch x 1.6-inch
EIDE or SCSI peripheral device Externally accessible 5.25-inch x 1.6-inch
EIDE CD-ROM drive Externally accessible 5.25-inch x 1.6-inch
EIDE floppy disk drive Externally accessible 3.50-inch x 1.0-inch

Remember the following when installing an optional peripheral device:

u

If you are installing a SCSI peripheral device, 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

Adding an internal SCSI peripheral device may limit the speed of the SCSI bus channel to
the speed of that device.

u

If you are installing a peripheral device 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” for details.

See the following chapters for related information and important details:

u

Chapter 4, “System Hardware,” for details on power supply cable connectors and pinouts.

u

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

To install a device in the available peripheral device bay:

1. Open the face panel.

36

2. Loosen the thumb screw on the locking plate near the top left corner of the peripheral

device bay.

Locking Plate
Thumb Screw

3. Lift the locking plate.

4. From inside the chassis, push the front of the tray and slide it out of the bay.

5. If you are installing a SCSI device, do both of the following (see Chapter 5,

“Peripherals,” for details):

−

Set the SCSI ID on the new drive to an unused ID number.

−

Disable termination on the new drive.
If you are installing an IDE device, proceed to the next step.

6. Do one of the following:

−

If installing a standard disk drive, place the disk drive in the tray, align the mounting

holes, and install the four mounting screws. See the following figure.

−

If installing a 5.25-inch device, such as a tape drive or a CD writer, remove the right

and left mounting guides from the drive tray and attach the right mounting guide to

the right side of the device, and the left mounting guide to the left side of the device.

7. Do one of the following:

−

Lift the locking plate, and install the tray assembly with standard disk drive into the

chassis, align the first slot on the mounting guide with the tab on the locking plate,

and lower the locking plate.

−

Slide the 5.25-inch device into the chassis, align the tab on the locking plate with the

first slot on the mounting guide, and lower the locking plate.

8. Tighten the thumb screw on the top of the locking plate to lock the drive into place.

9. Connect the proper interface cable (either SCSI or EIDE) and the power cable to the disk

drive.

Access Hole (2)

Adding External SCSI Peripheral Devices

You can connect additional SCSI peripheral devices to the external port of the SCSI adapter,
which is located in the expansion slots on the back of the system. Note that adding an external
SCSI peripheral device may limit the speed of the SCSI bus channel to the speed of that
device.

38

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 Ultra Wide SCSI drives. Fast SCSI, Ultra
SCSI, and Ultra Wide SCSI impose shorter cable restrictions than SCSI-1. The total length of
the SCSI cabling must not exceed the following:

Drives

One to four 19.8 ft

Five to seven 9.9 ft

SCSI-1 Fast SCSI-2 Ultra SCSI Ultra Wide SCSI

(6 meters)

(3 meters)

9.9 ft
(3 meters)

9.9 ft
(3 meters)

9.9 ft
(3 meters)

4.5 ft
(1.5 meters)

9.9 ft
(3 meters)

4.5 ft
(1.5 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:

u

Ultra Wide SCSI cable in the system−52 inches (132 cm)

u

Disk drive bay SCSI cable in the system−14 inches (35.5 cm)

u

SCSI cable inside each device−typically 8 inches (20 cm) or less

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 Computer Systems 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 controller 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

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 an External SCSI Drive

39

To connect an external SCSI drive:

1. Connect one end of the external SCSI cable to the connector on the back of the optional

SCSI card.

2. Connect the other end of the cable to the SCSI device.

3. Set the SCSI ID of the device to an unused number. See “SCSI ID Guidelines” above for

details.

4. Do one of the following:

−

If the device is the last or only device on the SCSI chain, enable SCSI termination.

−

If the device is the first device or is between the first and last 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.

System Board

See the System Board Manual for detailed information on the system board for your RAX
system.

Disk Drive Bay

The disk drive bay includes the disk drive cage and a Small Computer Systems Interface
(SCSI) backplane. This assembly is always replaced as one unit.

The SCSI backplane is a Low Voltage Differential Signal (LVDS) SCSI compliant backplane.
It is designed to connect up to four SCSI devices to a system in which the backplane is
installed. These SCSI devices must use the SCA-2 type connectors which incorporate
connections for power and status lines, as well as the signals comprising the wide SCSI bus.

Cable Routing and Pinouts

U7, U8, U9

SCSI drive connection is made through connectors J1 – 4. These are the only connectors on
the front of the backplane. Connection for the optional SCSI Accessible Fault-Tolerant
Enclosure (SAF-TE) card is through J18, which is a 72-pin SIMM connector.

CAUTION J18 is designed to connect only to a SAF-TE card. Do not connect a single inline memory

module (SIMM) to this location.

J15 and J14 are the 68 pin SCSI connectors for connecting the backplane to a host bus adapter
or RAID card. J15 is the input connector.

NOTE J14 should only be used to daisy-chain multiple backplanes.

J16 and J17 provide power (+12V, +5V, Ground) to the backplane. Both connectors must be
used for proper operation.

J20 and J21 are auxiliary bus connectors used in multiple backplane configurations only. J9 is
used only in multiple backplane configurations and should not be installed.

U7-9 are the LVD SCSI termination circuits. These provide the bus termination necessary for
proper operation.

Jumper Settings

RAID systems, which use the Mylex RAID controller, do not use any jumpers on these
headers. The spin-up delay and SCSI ID settings are controlled by the RAID controller and
SCSI backplane, respectively.

Disk Drive LEDs

Light-emitting diodes (LEDs) D1 through D8 are visual activity and status indicators for the

disk drives connected to the disk drive bay’s backplane. The LEDs are grouped in pairs above
each slot in the disk drive bay, and are visible behing the disk drive bay door.

Drive Status LEDs

The right LED above each disk drive flashes to show disk activity.

On a system with RAID disk drives, an optional SCSI Activity Fault-Tolerant Enclosure
(SAF-TE) card monitors the status of RAID disk drives. The SAF-TE card causes the left
LED above each disk drive to indicate RAID disk drive status, as follows:

47

Left LED Activity

Off No error
Steady on Disk drive rebuild stopped or disk drive is faulty
Steady blink (approx. 1 per second) Disk drive rebuild in progress
Fast steady blink (approx. 3 per second) Disk drive identification in progress
4 fast blinks, pause (repeats) Disk drive experienced a predicted fault
2 fast blinks, pause (repeats) Disk drive is a hot spare

The left LED functions only when the SAF-TE card is installed, and the backplane is
connected to a SAF-TE compliant host bus adapter or RAID card.

Power Supply

The 300 Watt power supply has a manual switch for selecting either 115 VAC (90-132 VAC)
range or 230 VAC (180-264 VAC) range for domestic or oversea locations. The input
frequency is 47-63 Hz, single phase. Input current is 5 amps maximum for the 115 VAC
range and 2.5 amps for the 230 VAC range. At full load, the power supply has a minimum
efficiency of 65 percent. The power supply is enclosed in a case that includes a fan to provide
additional airflow through the system.

The power supply has the following DC output specifications.

Hardware Monitoring

RAX systems feature advanced hardware monitoring capability. When used with InterSite
Hardware Monitor software, these features enable you to keep track such things as voltages,
temperatures, and fan speeds. For more information on the items that can be monitored on
your system, refer to Hardware Monitor Help.

Resistive temperature sensors are located on the system board near the processors and
expansion slots. These devices provide signals for reporting temperature readout data to the
InterSite Hardware Monitor software. The temperature sensors are part of the system board
and are not field replaceable.

NOTE InterSite Hardware Monitor software is not installed on RenderRAX III systems by default.

This product interrupts video streaming (causing dropped video frames) and consumes
rendering resources.
