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:
Do not touch the gold -plated finger contact s.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.
27
Before you install memory, do the following: 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.
Inspect DIMM contacts. The DIMM must have gold-plated fingers that match the gold-plated
socket contacts.
Follow these population rules to correctly install DIMMs: Install DIMMs one bank at a time; begin with bank 0 (nearest to the processor) or the first
open bank; end with bank 3.
Use only unbuffered ECC DIMMs specified for the system.
The following tables show possible memory configurations. Each bank contains one socket.

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 slo ts. 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.

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.
PCI cards contain configuration registers that define reso urce 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
Component Interconnect Specification, 2.1.
Non-compliant PCI cards mechanically comply with the Peripheral Component Interconnect
Specification 2.1, but do no t 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.
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.
PnP cards are ISA cards that contain configuration registers like PCI cards. During startup,
the system BIOS automatically detects the installed card and assigns the necessary system resources. Since a PnP card is ISA-based, you install it in any available ISA slot.
NOTE Assign system resources for any non-PnP ISA card and any non-compliant PCI
cards before installation. See the “Assigning System Resources” section below.
Each installed PCI card must draw less than 25 watts of power. The total allowable maximum wattage fo r PCI cards is 175 watts. The PCI slots are limited to 25 watts power dissipation per the Peripheral Component Interconnect Specification 2.1.

Installing Option Cards

For other cards, such as internal modems or SCSI adapters, see the documentation that came with the card for details on installation, configuration, cable connections, and operation.
To install an option 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.
30

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 option cards.
NOTE Treat non-compliant PCI cards and PCMCIA cards as ISA cards when assigning
system resources.

Adding Disk Drives to the Disk Drive Section

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.
CAUTIO Only use disk drives purchased from Intergraph in the disk drive bay. This ensures
the drives meet the disk drive section 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 Internal SCSI Drives and Devices

The CD-ROM drive and floppy disk 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 cage.
The following describes the devices in the peripheral device cage.
31
Drive
EIDE or SCSI peripheral device Externally accessible 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:
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.
Adding an internal SCSI peripheral device may limit the speed of the SCSI bus channel to the
speed of that device.
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 Ca rds” for details.
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, “Peripherals,” for details on internal drive locations, configurations, jumpers, and
cables.
Type Maximum Bay Capacity
To install a device in the available peripheral device cage:
1. Remove the front panel.
2. Disconnect the power and data cables from the CD-ROM drive and other peripherals in the
cage.
3. Remove the four screws at the top and bottom left and right of the peripheral cage that
attaches the peripheral cage to the chassis.
4. From inside the chassis, push the back of the CD-ROM or peripheral cage until the bezel
clears the front of the chassis, then slide the cage out.
5. Remove the drive tray in an unused bay of the c age by removing and retaining the scre ws that
mount the drive tray to the cage.
32
6. Install the new device in the open bay. If you are installing a SCSI device, do both of the
following (See Chapter 5, “Peripherals”, for details). (Mount the device in the open bay in the peripheral cage using the retained screws.)
Set the SCSI ID on the new device to an unused ID number.
Disable termination on the new drive.
If you are installing an IDE device, proceed to the next step.
7. If installing a 5.25-inch device, such as a CD writer, mount the device in the open bay in the
peripheral cage using the retained screws.
8. Slide the peripheral cage with the new device into the chassis (partially inserted to allow cable
connection).
9. Connect the proper interface cable (either SCSI or EIDE) and the power cable to the new
device.
10. With the cage partially inserted, re-connect the data and power cables to the peripherals in the
cage. There will be more room to re-connect these cables with the cage not fully seated.
11. With the cables attached, re-seat the peripherals cage and secure it to the chassis by re-
installing the four screws.
12. Re-install the face panel.

Floppy Disk CD-ROM Peripheral Expansion
Bays

Adding External SCSI Peripheral Devices

You can connect additional SCSI peripheral devices to the external por t of the SCSI adapter, which is located in an expansion slot 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.
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, Ultr a SCSI, and Ultra Wide SCSI impose shorter cable restrictions than SCSI-1. The total length of the SCSI cabling must not exceed the following:
33
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.
The total length of the SCSI cabling is the sum of the following:
Ultra Wide SCSI cable in the system52 inches (132 cm)Disk drive bay SCSI cable in the system−14 inches (35.5 cm)SCSI cable inside each devicetypically 8 inches (20 cm) or lessSCSI cable between the system and the first device
SCSI cable between each device
SCSI-1 Fast SCSI-2 Ultra SCSI Ultra Wide SCSI
9.9 ft
(6 meters)
(3 meters)
(3 meters)
9.9 ft (3 meters)

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.
9.9 ft (3 meters)
4.5 ft (1.5 meters)
9.9 ft (3 meters)
4.5 ft (1.5 meters)
Use the shortest cables possible to connect SCSI devices to the system and to each other.
34

SCSI ID Guidelines

By default, specific devices use the following SCSI IDs:
System disk drive (standard) uses ID 0SCSI controller always uses ID 7Read/write CD-ROM (optional) drive uses ID 44 mm DAT drive (optional) uses ID 6Iomega 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 Device

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 System Setup for more information.

System Board

See the System Board Manual for detailed information on the system board for the InterServe 90 system.

Disk Drive Section

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.

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.

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 indicato rs 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 behind the disk drive bay door.
Disk Activity 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:
Left LED Activity RAID Disk Drive Status
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 includ es a fan to provide additional airflow through the system.
