1 Accessing the System

This chapter lists hand tools and describes servicing restrictions, opening the base unit, avoiding electrostatic discharge, removing and attaching the face plate, and closing the base unit.

This system features a telescoping chassis that provides increased serviceability and access to internal components. The telescoping section, to which the system board is mounted, is secured by five screws and slides out from the rear.

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

CAUTION Follow all warnings and cautions in servicing instructions. Personal injury and damage to equipment

can occur if documented procedures are not followed.

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

discharge.

Tools

You will need the following tools to service the system:

Antistatic wrist strap

Quarter-inch nutdriver

No. 1 and No. 2 Phillips screwdrivers

Three-sixteenth-inch nutdriver

Five-sixteenth-inch or 8 mm nutdriver

Small single-slot screwdriver

Opening the Base Unit

CAUTION Shut the system down and turn the system power off. Use caution to avoid injury when removing

covers and other hardware.

CAUTION If the system is installed in a free-standing rack, ensure front and side stabilizers are fully extended.

To open the base unit:

1. Remove the screws that secure the face plate to the rack.

2. Slide the system out of the rack until it locks in the extended position.

3. Remove the following eight screws that secure the cover to the chassis: One at right and left top

corners of face plate; two at top, back of cover; and two at right and left sides, back of cover.

4. Slide the cover back about an inch, then lift the cover off.

5. Attach grounding clip from antistatic wrist strap to bare metal.

Protecting Against 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 the system’s internal components.

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

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.

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. A reusable antistatic wrist strap can be attached to any bare metal part of the base unit. The metal conductor bead in the elastic sleeve of reusable antistatic straps must contact bare skin.

Removing the Face Plate

To remove the face plate:

1. Remove the cover.

2. Remove one lower screw on each side of system front that secures handle to the base unit.

3. Remove the six screws that secure face plate to the base unit.

Adding Memory

You can upgrade memory on the MSMT353 or MSMT359 system board in 32 MB, 64 MB, 128 MB, and 256 MB increments; and the MSMT378 system board in 32 MB, 64 MB, and 128 MB increments. RenderRAX systems ship with all eight SIMM sockets populated.

Memory upgrade kits from Intergraph contain two SIMMs and a disposable antistatic wrist strap.

CAUTION System memory modules available from Intergraph have been 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 the SIMMs and voiding the warranty, take the following precautions.

Do not bend, twist, drop, or otherwise handle the SIMMs carelessly.

Do not expose the SIMMs to moisture or extreme temperatures.

Do not remove the SIMMs from the antistatic bag until installation.

Follow these SIMM population rules to correctly install the SIMMs.

Each bank has two slots. Fill both slots in a bank.

Use the same size SIMM in both slots in a bank.

After adding or replacing SIMMs, restart the computer. The new memory configuration is detected automatically.

The following table shows valid memory configurations. Each bank contains two sockets, and both sockets must be populated. Memory density must be the same in all populated sockets. NP designates the bank is not populated.

10. Restart the system. The new memory is recognized automatically.

A dding Processors to MSMT353 or MSMT359

You cannot add processors to the MSMT353 system board, since it ships with quad processors. The MSMT359 system board allows you to upgrade a single processor to dual processors and dual processors to quad processors. For the MSMT378 system board, you can upgrade a single processor to dual processors and Pentium Pro to Pentium II.

Single to Dual Upgrade

Single to dual processor upgrade kits include a CPU with attached heat sink, a voltage regulator module (VRM), and a metal clip.

To upgrade a single processor system:

1. Open the base unit and remove the necessary parts as described in Chapter 1.

NOTE If full-length ISA option boards are installed, they must be removed to access the CPU sockets.

2. Find the empty processor socket (adjacent to the existing CPU) on the system board. Raise the

lever on the empty socket to open the socket.

3. Install the new CPU into the socket. The CPU socket is keyed to ensure proper insertion.

4. Lower the lever to lock the CPU in the socket.

5. Attach the metal clip over the new CPU. Examine how the clip on the first CPU is installed to

see how it should fit on the new CPU. Ensure each end of the clip fully engages the socket tabs.

Adding Option Boards

Peripheral Component Interconnect (PCI), non-compliant PCI, Industry Standard Architecture (ISA), and Plug-n-Play (PnP) option boards may be installed in the system. A general description of the types of boards is provided below.

PCI boards contain configuration registers that define resource information to the system during startup. PCI boards do not require manual system configuration when installing the board. 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. The system’s PCI slots are limited to 25 Watts power dissipation per the Peripheral Component Interconnect Specification,

2.1. Installed PCI boards must draw less than 25 Watts of power. Also, the total power consumed by all PCI boards in the system should be less than 180 Watts.

NOTE All PCI option boards sold by Intergraph fully comply with the

Specification, 2.1.

Non-compliant PCI boards mechanically comply with the Peripheral Component Interconnect

Peripheral Component Interconnect

Specification 2.1, but do not contain configuration registers that allow the system to automatically assign the necessary resources. These boards install in PCI slots, but you assign system resources manually using the System Configuration Utility (SCU) before installing the board. In this regard, they are like ISA boards, as described below.

ISA boards do not contain registers that define the resource information to the system during startup. Therefore, you must run the SCU to define the board to the system before installing the ISA board. This reserves system resources for the board and prevents conflicts with ISA option boards already installed. Refer to the section, “Assigning System Resources” later in this chapter.

PnP boards are ISA boards that contain configuration registers like PCI boards. During startup, the system BIOS automatically detects the installed board and assigns the necessary system resources. Since PnP boards are ISA-based boards, they must be installed in the ISA slots.

PCI slots are on Side One of the riser card; ISA slots are on Side Two.

NOTE Assign system resources for ISA and non-compliant PCI boards before installation. Refer to the

section, “Assigning System Resources” later in this chapter.

Installing an Option Board

To install option boards:

1. Open the base unit as described in Chapter 1. If installing an ISA card, the internal disk drive

bay must be removed to access ISA slots. Refer to “Internal Bay Disk Drives” in Chapter 2 for instructions on removing the internal disk drive bay.

2. Using a quarter-inch nutdriver, remove the blanking plate from an available slot. If installing a

PCI card, loosen the two screws securing the board clip to the PCI card guide (just behind the power supply), and slide the board clip forward.

3. Install the option board. Press firmly to ensure the board seats completely into the slot.

4. Secure the board to the chassis using the screw removed previously. If installing a PCI card,

slide the board clip back and tighten the two screws.

5. Connect any cables to the board as required by the manufacturer.

6. Close the base unit and restart the system.

NOTE For PnP boards, notice when the following message displays: Hit DEL if you want to run

SETUP

. Press DELETE to run AMIBIOS Setup, and enable the Boot to PnP Operating System

parameter under PnP Setup menu. Exit AMIBIOS Setup and restart the system.

Assigning System Resources

Some option boards include a configuration diskette that you can use to reserve the system resources required for the board. Other option boards do not include a diskette, but require that you manually enter the configuration information. The next two sections describe how to reserve the resources for both types.

The System Configuration Utility (SCU) is an MS-DOS utility that will not run in the Windows NT environment. Use the System Utilities (SYSUTIL) diskette delivered with your system to boot the system into MS-DOS. The system must be set to boot from the floppy disk drive (normally drive A)

to use the SCU. If necessary, refer to “Changing the System Boot Sequence” in the System Setup.

NOTE For a list of available system address resources (DMA, I/O, memory) refer to Chapter 5 or 6.

NOTE Treat non-compliant PCI boards and PC Cards as ISA boards for assigning system resources.

Option Boards with a Configuration File

Some ISA boards are shipped with a diskette containing a configuration file. The configuration file can be loaded to the system so that the BIOS reads this file to assign resources during startup. If you install ISA boards that are shipped with a configuration diskette, follow this procedure.

NOTE If a configuration diskette is not delivered with the option board, refer to “Option Boards without a

Configuration File.”

To configure option boards with a configuration file:

1. Shut down and power off the system.

2. Insert the SYSUTIL diskette into the floppy diskette slot of the combo drive; then restart the

system.

3. When the MS-DOS Startup menu displays, select option 1 to run the SCU.

Adding Internal SCSI Drives

The front of the system allows four 5.25-inch drives to be installed—two drives in the horizontal bay and two in the vertical bay. There is also an internal bay that accepts two 3.5-inch drives.

In StudioZ RenderRAX workstations and InterServe 615R and 625R servers, one disk drive is installed in the left slot of the vertical bay. A CD-ROM is installed in the lower slot of the horizontal bay. The two internal drive bays are empty. The disk drive uses SCSI ID 0 and the CD-ROM drive uses SCSI ID 4.

In the TDZ-425 RAX and TDZ-612 RAX, one removable disk drive module is installed in the left vertical bay. A CD-ROM drive is installed in the lower horizontal bay. The two internal drive bays are empty. The disk drive uses SCSI ID 0, the SCSI CD-ROM drive in the TDZ-612 RAX drive uses ID 4, and the EIDE CD-ROM in the TDZ-425 RAX uses the primary EIDE bus and the mode select header is set to “Master.”

The Adaptec AIC-7880 controller on the riser card provides Ultra Wide SCSI for internal drives in all rack-mounted systems.

When installing a SCSI drive, have the vendor’s documentation available to follow instructions for setting SCSI IDs for SCSI drives, installing device drivers when required, and configuring other drive attributes necessary for operation.

If installing a drive that connects to an adapter card (such as an EIDE drive), refer to the vendor’s documentation for installing the adapter card and required cables. The previous section, “Adding Option Boards,” provides information about PCI and ISA slot locations in the system.

If installing a Kingston removable disk drive module, refer to the vendor’s documentation for installing the module, removing terminators, and setting the SCSI ID.

If installing a Fast SCSI (Narrow) drive, use the 68 pin to 50 pin adapter (CCON401B), provided with the system. If you install a non-Wide SCSI device, the data transfer rate is limited to that device's speed.

Refer to Chapter 9, “Peripherals,” for details on drive configurations, jumpers, and cables.

NOTE Internal SCSI drives are not terminated. The internal SCSI cable provides termination. You must

remove termination from any drive that you install in the system.

SCSI IDs should be set for the drives using the following guidelines:

Slot Location

Left Vertical System disk drive 0 Right Vertical Add-on disk drive 1 Left Internal Add-on disk drive 2 Right Internal Add-on disk drive 3 Lower Horizontal CD-ROM drive 4 Upper Horizontal Other drive type 5 or 6

To install a drive into the internal drive bay:

1. For SCSI devices, disable the SCSI termination, and set the SCSI ID for the drive to an unused

number.

2. Remove the top cover from the base unit as described in Chapter 1.

3. Disconnect the fan power cable. Note the location where the fan power cable connects to the

Adding External SCSI Drives

You can add single-ended external SCSI drives to the system by connecting them to the SCSI port on the back of the base unit. Additional SCSI option boards (adapters) can be installed to support external SCSI drives as well. The section “Adding Option Boards” earlier in this chapter describes installing new boards.

The Adaptec AIC-7860 SCSI controller (on MSMT353, MSMT359 and MSMT378 system boards) provides the Ultra SCSI bus for external devices.

Screws (Two each side)

SCSI Cable Guidelines

If you are using a SCSI adapter card, this information also applies.

The number of drives and length of the cables used to connect the drives becomes 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

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

1 to 4 19.8 feet (6 meters) 9.9 feet (3 meters) 9.9 feet (3 meters) 9.9 feet (3 meters) 5 to 7 9.9 feet (3 meters) 9.9 feet (3 meters) 4.5 feet (1.5 meters) 4.5 feet (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:

SCSI cable inside the base unit - 6.0 inches (15 cm)

SCSI cable inside each device - average 8 inches, (20 cm)

SCSI cable between the base unit and the first device

SCSI cable between each device

Connecting the Drive

To add an external SCSI drive:

1. Connect the SCSI cable to the SCSI port on the base unit and to the device.

2. Set the drives SCSI ID to an unused number (1, 2, 3, 5, or 6). By default, the following devices

use these SCSI IDs:

−

System disk drive uses ID 0.

−

CD-ROM drive uses ID 4.

−

SCSI bus uses ID 7.

3. Disable or enable the drive’s SCSI termination according to the vendor’s instructions. The last

external drive on the SCSI cable chain must have SCSI termination enabled. All other external drives must have SCSI termination disabled.

4. If necessary, install the software drivers and configure the drive according to the vendor’s

instructions.

Disabling Sync Negotiation

Use the following instructions if you need to disable the sync negotiation, which forces the controller to transfer data at a specified rate (slower than its capability) for the target drives.

To disable sync negotiation:

1. Power off the system and reboot into DOS using the SYSUTIL diskette.

2. From the SYSUTIL main menu, select SCSISelect Utility.

3. From the Options box, select Configure/View Host Adapter Settings.

4. Select the SCSI Device Configuration option.

5. Change the Initiate Sync Negotiation values for all the attached SCSI drives

(represented by their SCSI ID number) to no.

6. Set the Maximum Sync Transfer Rate values for the drives to the desired settings. If

changing these settings to extend cable lengths or add more devices, set Fast SCSI-2 drives to

8.0. (or less if available).

7. Press

ESC until the Exit Utility dialog displays. Select Yes and press ENTER.

8. Press any key to restart the system.

The Vibra 16C sound controller is configured entirely through I/O port accesses. When the system is powered up, the hardware forces the Vibra 16C 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 controller configurations and available programmable settings.

PCI to ISA Bus Interrupt Mapping

The ISA bridge (Intel 82379AB) or MSMT359 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.

The 8-bit PIRQ Route Control Registers in the ISA bridge determine to which ISA interrupt a PIRQ or MSMT359 is routed. Four PIRQ Route Control Registers are used for the PCI interrupts, located at the ISA bridge address offsets defined below.

PCI Interrupt Request

PIRQ0 60 PIRQ1 61 PIRQ2 62 PIRQ3 63

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 will be routed, as defined below.

The spare interrupts listed above may be assigned to PCI and ISA devices. When you add a PCI device to the system, the interrupt will be automatically assigned by the system BIOS. However, at least one interrupt must be available for the PCI bus. For increased performance, one interrupt should be left available for each PCI based controller used in the system. When you add a ISA board, you must assign the interrupt using the System Configuration Utility and jumpers on the option board.

PCI to ISA Bus Interrupt Mapping

The ISA bridge (Intel 82371SB) 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.

Each PCI slot on the riser card has four available interrupt lines: INTA, INTB, INTC, and INTD. These are connected to the PCI interrupts, PIRQ0 through PIRQ3, as shown below:

ISA Bus

INTA PIRQ0 PIRQ1 PIRQ2 PIRQ3 PIRQ0 PIRQ1 INTB PIRQ1 PIRQ2 PIRQ3 PIRQ0 PIRQ1 PIRQ2 INTC PIRQ2 PIRQ3 PIRQ0 PIRQ1 PIRQ2 PIRQ3 INTD PIRQ3 PIRQ0 PIRQ1 PIRQ2 PIRQ3 PIRQ0

The ISA slots on the MSMT463 riser card accommodate ISA based option boards and a 16-bit wide expansion bus. The ISA bus interrupt (IRQ) assignments are defined below.

Expansion Slots

The riser card has six PCI slots and four ISA slots. PCI slots 5 and 6 are on the primary PCI bus, supported by the PCI bridge on the system board. PCI slots 1 through 4 (secondary) are supported by an Intergraph programmable part on the riser card. Some PCI option boards must be installed in a primary PCI slot, as stated in the documentation delivered with the option board.

Systems with the MSMT359 system board have onboard G95 video. Other systems that do not use onboard G95, such as RenderRAX, use the G95 card (MSMT340) in PCI slot 5, or other graphics board in specified slots (see below).

NOTE Full-length PCI cards cannot be installed in PCI slot 6 if the processor module is installed on system

board MSMT353. The processor module is used in quad-processor systems only.

Internal SCSI Controller

The system’s internal SCSI controller is the Adaptec AIC-7880. All internal SCSI devices use the AIC-7880.

SCSI Connector

The SCSI connector is on side 2 of the riser card. The cable MCBL234A connects to the SCSI connector and to the internal SCSI devices. The following shows the cable pinout. Pins not listed in the table are connected to Ground.
