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

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

discharge.

“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:

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

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.

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

Touch the bare metal of the base unit to ensure the base unit 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 in the elastic sleeve of reusable antistatic straps must contact bare skin.

Opening the Base Unit

CAUTION Before you open the base unit, 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 removing covers and other hardware.

CAUTION Ensure the front and side stabilizers of the rack in which the system is moun ted 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 right corners of the back of the chassis.

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

6. Attach the grounding clip from the antistatic wrist strap to bare metal.

Opening and Closing the Face Panel

To open the face panel:

1. Loosen the two thumb screws that secure the face panel to the base unit (on the upper

right and left corners of the face plate).

2. Pull the face panel toward you to open it. The face panel swings down on hinges attached

to the lower corners of the base unit, as shown in the following illustration.

To close the face panel:

1. Lift the face panel upward and push it onto the base unit.

2. Secure the face panel to the base unit by tightening the two thumb screws.

Closing the Base Unit

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.

To close the base unit:

1. Remove the antistatic wrist strap from the base unit.

2. Replace the cover.

3. Secure the cover to the base unit with the screws retained earlier.

4. Slide the base unit into the rack.

JBOD or RAID Disk Drives

The disk drive bay may contain up to four non-RAID (JBOD) or RAID drives. The replacement procedure for these drives is similar.

To replace disk drives:

1. Open the drive access door on the front of the system.

2. Flip the drive latches outward to disengage the disk drive. Wait 30 seconds to allow the

drive to spin down and park the heads.

3. Carefully eject the drive completely from the rails, and remove it from the disk drive

section.

WARNING Handling a spinning drive or mishandling a removed drive can cause the heads to

crash! Subsequent failures may not be noticeable for three to six months. Handle disk drives carefully to avoid damage.

4. Remove the drive mounting plate from the removed disk drive, making sure to retain the

mounting plate screws. Attach the mounting plate to the bottom (circuit board side) of the new drive, using the four screws you retained from the removed drive.

WARNING Removing and attaching the drive mounting plate requires careful handling to avoid contact

with the delicate, electrostatic-sensitive parts on the circuit board of the drive. All drives must be handled carefully to prevent failure and voiding the warranty for the drives.

5. To insert the new drive, extend the latching clips on the disk drive and align the rails on

the sides of the drive with the slot guides. The metal casing of the drive faces left.

slides all the way into the slot and firmly engages the connector.

7. Close the latching clips to lock the drive in the slot.

8. If the system has a RAID configuration, verify that the drive status LED lights. Its

behavior is dependent on the status of the array that the drive is in.

9. Label the new drive with the same ADP, CH, and ID numbers used on the replaced drive.

Disk Drive Section (MESAP02)

The disk drive section includes the disk drive cage, backplane, and LEDs. This assembly is always replaced as one unit.

To replace the disk drive section:

1. Remove all the drives from the disk drive section (see steps 2 and 3 above in “JBOD or

RAID Disk Drives”). Note the original slot location for each drive. The drives should be reinstalled in the same slot locations from which they were removed.

2. Remove and retain the six screws that attach the disk drive section to the chassis.

Support the drive section as the last screw is removed.

5. Disconnect the power cables attached to the disk drive section, using caution to avoid

damage to the cables and components on the disk drive backplane. Do not pull on the wires of the power cables to remove them from the plugs, as damage to the cables will occur.

6. Slide the disk drive section the rest of the way out of the chassis.

7. Verify that the jumper settings on the back of the replacement disk drive section match

the one being replaced.

NOTE If the system uses the Mylex RAID controller, the jumper connectors JP2 and JP3 must not

have any jumpers installed.

9. Remove the SAF-TE card (as described in the next section) from the old disk drive

section, and replace it in the same location on the new disk drive section.

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

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

drive section.

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

screws removed earlier.

13. Insert the disk drives into the system. 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

The SCSI Activity Fault-Tolerant Enclosure (SAF-TE) card is only used on systems with RAID configurations. If your system has a RAID configuration, use the following procedure to replace the SAF-TE card.

To move or replace the SAF-TE card:

1. Remove the disk drive cage as described above in “Disk Drive Section.” The SAF-TE

card is located in the middle of the SCSI backplane.

2. Press the two metal clips on the outside of the SAF-TE card mounting slot away from

each other, then gently rotate the SAF-TE card to a vertical position and remove it.

3. Place the SAF-TE card vertically in the mounting slot and rotate it toward the metal clips

until it snaps into place, with the clips securing the card. Use caution to avoid applying too much force, as damage to the SAF-TE card and/or the disk drive backplane may result.

4. Replace the disk drive cage as described above in “Disk Drive Section.”

Bus Terminator

The bus termination card (MSMT379) is used only in systems with one processor. The card provides termination for the processor bus. Single-processor systems will not operate without the card installed. See the system board diagrams in Chapter 5, “System Board,” for connector and socket locations.

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 upgrading 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 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.

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). Memory upgrade kits from Intergraph Computer Systems contain one DIMM and a disposable antistatic wrist strap.

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

Do not touch the gold-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 you are ready to install them.

Before you install memory, 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 goldplated socket contacts.

Follow these population rules to correctly install the DIMMs:

Remember that you must install DIMMs one at a time.

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

Press the DIMM into the socket at a 90 degree angle. Do not rock the DIMM; apply even pressure along the top edge of the DIMM.

Memory Configurations

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

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

Chapter 5, “System Board,” for socket locations.

See Chapter 2, “Servicing the System,” to install a memory upgrade. Restart the system after adding or replacing DIMMs. The computer detects the new memory automatically.

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 diagrams in Chapter 5, “System Board,” 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 secondary processor terminator card from the secondary processor slot, as

shown in the following figure.

Secondary processor

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

“Servicing the System,” for details.

terminator card

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.

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 Computer Systems fully comply with the

Component Interconnect Specification, 2.1.

Non-compliant PCI cards mechanically comply with the Peripheral Component

Peripheral

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” later in this chapter.

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 option slots are located at the back left section of the system board. When viewed from the front of the base unit, the right-most slot is an AGP slot; the left-most slot is an ISA slot. The order of the slots is shown in the following figure.

ISA Slot

PCI Slot

AGP Slot

Upgrading Graphics Cards

The Matrox G100 video adapter is available for the InterServe 80 SL Rack Mount system.

See Chapter 7, “System Specifications,” for details.

Intergraph Computer Systems installs the graphics card into the AGP slot by default.

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. Locate an open slot. If you are installing an Intergraph Computer Systems graphics card,

see the figure above for required slot assignments.

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

3. Remove the option card from its antistatic packaging.

4. 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.

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

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

7. Install the retaining screw.

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

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 Chapter 5, “Configuring the BIOS” in the InterServe 80 SL Rack Mount 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.

The following sections list the available system resources. See the vendor documentation delivered with an option card or a peripheral device for instructions on how to use these resources.

Size Assignment

Reserving an IRQ

Most ISA devices installed in the system require you to reserve an IRQ. PCI devices also need to use an IRQ, but since they share system resources they can use the same IRQ. At least one IRQ must be left unassigned, for use with any PCI devices installed in your system. The system has a limited number of open IRQs. To install more ISA devices than you have open IRQs, you must disable one unused system port for each excess ISA device, unless the device does not require an IRQ.

To reserve an IRQ for an installed device:

1. Restart the system and start the BIOS Setup program.

2. On the PCI/PnP screen, select the IRQ you want to reserve.

3. Change the setting for the selected IRQ to ISA/EISA.

4. Save the changes and exit from the BIOS Setup program.

The following option cards require specific system resource settings, as noted:

Option card (installed)

First modem (Windows NT) COM1, IRQ 4 Disable serial port 1 (COM1);

Second modem (Windows NT) COM2, IRQ 3 Disable serial port 2 (COM2);

First parallel printer adapter Base address 278 None Second parallel printer adapter Base address 3BC None 3Com network adapter IRQ 10 (default) Reserve IRQ 10

Resources required

Adding Hard Disk Drives

The InterServe 80 SL Rack Mount system is configured to support either RAID or non-RAID (JBOD) disk drive configurations.

RAID Configurations

RAID capability is provided by the single-channel Mylex RAID controller and a SCSI Activity Fault-Tolerant Enclosure (SAF-TE) card in the disk section. The non-RAID system uses a plug-in single-channel Wide Ultra SCSI controller, which does not provide RAID capabilities.

BIOS Setup parameter settings

reserve IRQ 4

reserve IRQ 3

For a system with internal RAID, three RAID disk drives, with the operating system and system software, are standard. These drives, called boot drives, are labeled with specific adapter, channel, and SCSI ID. They must be installed in specific slots in the disk section. Refer to the System Setup for installation instructions.

CAUTION The RAID controller has one external connector on the back of the system and is non-

functional. Connecting a peripheral device to the connector can result in system failures and

loss of data. Refer to Chapter 5, “System Board,” for more information.

NOTE Only use disk drives purchased from Intergraph in the disk array. This ensures the drives

meet the disk array specifications.

SCSI Configurations

Non-RAID systems are configured to support Just a Bunch of Disks (JBOD) functionality. The InterServe 80 SL Rack Mount system can support up to four JBOD disks. One disk drive, with pre-installed operating system and system software, is standard. This drive is called the boot drive. It is labeled with specific adapter, channel, and SCSI ID. The boot drive must be installed in the lowest slot of the disk section. If additional drives are ordered, they may be delivered formatted.

Refer to the System Setup for disk installation instructions.

Adding Internal SCSI Drives and Devices

The system features the following peripheral bays:

•

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

•

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

•

One 5.25-inch x 1.6-inch external bay for other peripheral devices.

Note the following restrictions on adding peripheral devices:

•

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

•

Internal or external SCSI devices require an additional SCSI controller card. Refer to "Adding Option Cards" earlier in this chapter for information about adding option cards to the system.

See the following chapters for related information and important details:

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

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.

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 (such as an EIDE drive), see the vendor’s documentation for installing the adapter card and required cables. See “Adding Option Cards” earlier in this chapter for details.

If you are installing a removable disk drive module, see the vendor’s documentation for installing the module, removing terminators, and setting the SCSI ID.

Device Bays

You can add optional mass storage devices to the external bay. The EIDE CD-ROM, floppy drive, and system drive are standard. Other devices are available as options.

The following table lists the device bays and provides related information.

Installing Devices in the Drive Bays

To install a drive in the external drive bay:

1. Open the face panel.

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

Locking Plate Screw

3. Lift the locking plate.

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

NOTE SCSI devices are only supported if an additional SCSI controller is added to the system.

5. If you are installing a SCSI device, do both of the following (see Chapter 6,

“Peripherals,” for details):

−

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

−

Disable termination on the new drive.

6. If you are installing an IDE device, proceed to the next step.

7. 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.

8. 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.

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

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

drive.

Adding External SCSI Drives

If your system has an optional SCSI adapter, you can install additional external SCSI drives to the system. If you do not have the optional SCSI adapter, you can install additional SCSI

expansion cards (adapters) to support SCSI drives. See “Adding Option Cards” earlier in this chapter for details.

NOTE Most SCSI adapters do not recognize a hard disk drive that was formatted using a different

brand of adapter. For example, a hard disk drive formatted with an Adaptec SCSI adapter will not work with a Symbios SCSI adapter. You must use only Symbios-formatted hard disk drives with a Symbios SCSI adapter.

SCSI Cable Length Guidelines

The number of drives and length of the cables used to connect the drives is a factor when using SCSI-1, Fast SCSI (SCSI-2), Ultra SCSI, and Wide Ultra SCSI drives. Fast SCSI, Ultra SCSI, and Wide Ultra SCSI impose shorter cable restrictions than SCSI-1. The total length of the SCSI cabling must not exceed the following:

Drives

One to Four 19.8 ft

Five to Seven 9.9 ft

NOTE The SCSI controller (on the system board or an adapter card) counts as one device.

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

(6 meters)

(3 meters)

9.9 ft (3 meters)

4.5 ft (1.5 meters)

9.9 ft (3 meters)

4.5 ft (1.5 meters)

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 Computer Systems 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 controller 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 an External SCSI Drive

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.

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.
