1 Accessing the System

This chapter lists tools and describes protecting against electrostatic discharge. It also describes opening and closing the case, and accessing components behind the power supply.

This system features a new, extensible chassis architecture designed for ease of upgrades and expansion. The design provides easy access to PCI and ISA card slots, memory, processors, and the power supply. You do not need any tools to open the InterServe 80 case.

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

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

discharge.

WARNING 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.

Tools

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

Protecting Against Electrostatic Discharge

Electrostatic discharge (ESD) can damage sensitive components inside the unit. Take the following precautions when working with internal components:

Unplug the unit from AC power before servicing any electronic component inside the chassis. Remember that the InterServe 80 is always on when connected to AC power.

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

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.

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.

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.

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.

Press up on release located under lip

3. Keep pressing the release, slide the top cover back until it stops, remove it from the chassis, and

set it aside.

4. Do the following to remove a side panel.

−

Grasp the cowling at the bottom of the side panel and lift.

−

Slide the side panel back until it stops, and then remove it from the chassis.

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 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 above 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.

A ccessing Component s Behind the Power Supply

The power supply swings away from the system board, giving you easy access to the processors, DIMMs, and other components. You can remove the power supply entirely, but this is not necessary 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.

4. Grasp both knurled plungers on the power supply, pull them toward each other, and then swing

the power supply toward you.

Top plunger

Bottom plunger

NOTE Disconnect power cables to internal devices as needed to allow the power supply to swing out fully.

5. Access the exposed components as needed.

To stow the power supply:

1. Reconnect any power cables that you disconnected.

2. Grasp both knurled plungers, pull them toward each other, and then swing the power supply

away from you, back into the chassis.

CAUTION Carefully swing the power supply back into the chassis. Avoid pinching cables. Hold the external

SCSI cable against the chassis brace or rearrange cables slightly while swinging the power supply into the chassis.

3. Align the plunger holes and release both plungers.

4. Install the retaining/grounding screw on the rear panel.

5. Install the left side panel and top cover.

6. Plug the AC power cord into its connector on the rear of the chassis.

2 Servicing the System

This chapter describes how to replace the standard parts within the system. Heed all warning and caution labels while replacing parts. These servicing procedures assume you have removed the left side panel from the system, and have taken antistatic precautions, as described in Chapter 1. After you have finished servicing the system, replace panels as described in Chapter 1.

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.

WARNING Disconnect the system 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 servicing instructions. If you fail to follow documented,

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

3 Upgrading the System

This chapter describes upgrading memory and processors, as well as installing option cards, internal SCSI drives, and external SCSI drives. Obey all warning and caution labels while replacing parts. These servicing procedures assume you have removed the left side panel from the system, and have taken antistatic precautions, as described in Chapter 1. After you have finished servicing the system, replace panels as described in Chapter 1.

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.

WARNING Disconnect the system 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 servicing instructions. If you fail to follow documented,

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

Adding Memory

You can upgrade memory on the system board in 32, 64 MB, or 128 MB increments. The maximum total memory is 512 MB. Memory upgrade kits from Intergraph contain one DIMM and a disposable antistatic wrist strap.

CAUTION System memory modules from Intergraph 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 purchased from a non-Intergraph source, 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 gold-plated socket contacts.

The following table shows possible memory configurations. Each bank contains one socket. NP designates the bank is not populated.

3. Locate the DIMM sockets and ensure the release tabs on either end of the socket are open.

4. Install DIMMs one bank at a time in sequence from socket 0 to socket 3, beginning with the first

open socket.

5. Grasp the DIMM so that the notch positions match the keys in the socket. See the illustration in

the section, “DIMMs,” in Chapter 2.

6. Insert the DIMM at a 90-degree angle into the socket.

7. Press the DIMM straight down into the socket. Do not rock the DIMM; apply even pressure

along the top edge of the DIMM until the release tabs snap into place.

8. Swing the power supply back into the chassis and secure it with the plungers.

9. Restart the computer after adding or replacing DIMMs. The computer detects the new memory

automatically.

Adding a Processor

Systems with a single 300 MHz processor system are upgradeable to dual 300 MHz processor. You can install a processor module with heat sinks (CICM452, Intergraph standard part) or a boxed processor module with integral fan (non-Intergraph part). Single-to-dual processor upgrade kits include a CPU with attached heat sink and a voltage regulator module (VRM).

The lower right heat sink fin on the Intergraph processor module must be removed to provide clearance for the fan connector at J5 on the 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 for the location of processor slots and related connectors.

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 for details.

2. Remove the 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 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 Option Cards

You can install Peripheral Component Interconnect (PCI), non-compliant PCI, Industry Standard Architecture (ISA), and Plug-n-Play (PnP) option 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.

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

Specification, 2.1.

Non-compliant PCI cards 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 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.

NOTE Assign system resources for an ISA card and any non-compliant PCI cards before installation. See

“Assigning System Resources” on page 29.

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 below. 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)

Upgrading Graphics Cards

The following graphics cards are available for InterServe 80.

MSMT223 - Intergraph G90

MSMT381 - Intergraph Intense 3D 100

Intergraph installs the graphics card into PCI slot 4 by default. If necessary you can move the card to PCI slots 1, 2, or 3. Do not install graphics cards in PCI slots 5, 6, or 7. See the following procedure for steps to install a graphics card.

Installing Option Cards

For cards, such as internal modems or SCSI adapters, see the documentation that came with the card for additional information on installation, and for details on configuration, cable connections, and operation.

To install an option card:

1. Remove the top cover and left side cover as described in Chapter 1.

2. Locate an open slot. If you are installing an Intergraph graphics card, see the table above for

required slot assignments.

3. Remove the blanking plate for the slot. Keep the retaining screw.

4. Remove the option card from its antistatic packaging.

5. Slide the option card carefully into the card guides. Ensure that the gold-fingered connectors on

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

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

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

8. Install the retaining screw.

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

10. Install covers and restart the system. If necessary, assign system resources to the new card.

Assigning System Resources

Some option cards include a configuration diskette that you can use to reserve the system resources required for the card. Other option 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 InterServe 80 System Setup for details on assigning system resources and configuring the BIOS for option cards.

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 system features the following peripheral bays:

One 3.5-inch x 1-inch external bay for floppy or combo drive.

One 5.25-inch x 1.6-inch external bay for CD-ROM drive.

Two 5.25-inch x 1.6-inch external bays for disk drives or other devices.

Three 3.5-inch x 1-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 internal drive locations, configurations, jumpers, and cables.

Chapter 7, “Power Supply, Fans, and Hardware Monitoring Devices,” 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.

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 “Adding Option Cards” on page 27 for details.

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 The internal SCSI cable provides termination for the SCSI bus. When installing internal SCSI drives,

be sure to disable SCSI termination on the drives.

Adding External SCSI Drives

You can add single-ended external SCSI drives to the system by connecting them to the Ultra SCSI

port on the back of the system. A Wide Ultra SCSI external port is optional. See “External Ports” in Chapter 5 for an illustration of port locations.

You can also install additional SCSI option cards (adapters) to support external SCSI drives. See “Adding Option Cards” on page 27 for details.

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 19.8 ft (6 meters) 9.9 ft (3 meters) 9.9 ft (3 meters) 9.9 ft (3 meters) 5 to 7 9.9 ft (3 meters) 9.9 ft (3 meters) 4.5 ft (1.5 meters) 4.5 ft (1.5 meters)

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

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:

Wide Ultra SCSI cable inside the system - 52 inches (132 cm)

Ultra SCSI cable inside the system - 14 inches (35.5 cm)

SCSI cable inside each device - typically 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.

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

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

4 mm DAT drive (optional) uses ID 6

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:

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 Drive

To add an external SCSI drive:

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. 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.

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 delivered with the system for details.

disconnected from AC power. To return the system to the Working state, you

must reconnect the power cord and perform a full system shutdown and restart using the Automatic Shutdown Utility.

Temperature Sensors

Resistive temperature sensors are located on the system board at U1 and U143, 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 U143 provides the signal for controlling fan speed. The temperature sensors are part of the system board and are not field replaceable.

Dynamic Fan Speed Control

Specialized components control dynamic fan speed, based on temperature measured by two sensors, and whether the temperature is rising or falling. Fan speed is calculated based on the average (or composite) of all three fans. The following table defines composite fan speeds identified by the hardware monitoring components.

Composite Fan Speed

High High High High Medium High High High Low Medium Low High Low Low Low Low Low Low

Chassis Fan 1 Chassis Fan 2 Power Supply Fan

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 rises above setpoint T1, composite fan speed increases to medium low.

Temperature Setpoint

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:

Interrupt Line

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

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.

Name IRQ Name

When you add an ISA board, you must reserve the interrupt using the AMIBIOS Setup utility and jumpers on the option board. See the System Setup delivered with the system for details on using AMIBIOS Setup. See also the vendor documentation for the option board for jumper and related information.

7 Power Supply and Cooling Fans

This chapter describes the power supply, power-related pinouts, and cooling fans.

Power Supply

MPWS152 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 InterServe 80 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. See Chapter 2 for instructions to replace the power supply.

The following table details the DC output specifications for the power supply.

The following notes apply:

1. Power supply should meet or exceed these specifications.

2. The maximum combined continuous load of all outputs shall not exceed 500 Watts.

3. The maximum combined continuous load of the +5.0V and +3.3V outputs shall not exceed 385

Watts.

4. The +12 V output must be able to supply a peak current of 17 amps for 30 seconds.

5. Current will always be flowing from the +12V (or −12V) output to the fans.

6. The 5V AO (Always On) output remains ON with the AC input power connected, whether the

power supply DC outputs are disabled (OFF) or enabled (ON) by the power-up circuitry.

Cable Connectors

The following table lists the cable connectors from the power supply that connect to the system board and other devices.

Cooling Fans

The system 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 the vents. The table below summarizes fan information.

The two chassis fans (CFAN120) are field replaceable. Refer to Chapter 2 for instructions to replace the chassis fans. The power supply fan is not field replaceable. If the fan requires replacement, you must replace the power supply.

Size Location Airflow Devices Cooled Connector

See Chapter 5 for connector locations and fan cable pinouts.

Arrows on each fan indicate airflow direction and rotation, as shown:

If you replace a chassis fan, ensure that you install the fan with the airflow direction arrow pointing toward the inside of the chassis.

Refer to Chapter 4 for information about fan speed control.
