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

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.

♦ Disconnect the base unit from AC power before opening the base unit. ♦ Touch the bare metal of the base unit chassis before touching any internal components. ♦ Handle all printed circuit boards as little as possible and only by the edges. ♦ 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 you use a disposable wrist strap, you cannot use it again.

♦ Attach an antistatic wrist strap to any bare metal part of the base unit chassis. The metal

conductor in the elastic sleeve of a reusable antistatic strap must contact bare skin.

Opening the Base Unit

WARNING The system is always on when connected to AC power. Before opening the

system, disconnect the system’s power cord from its AC power outlet.

WARNING Replace the cover before operating the system. This ensures proper airflow for

cooling and reduces electromagnetic interference (EMI) emissions.

2 Upgrading the System

This chapter describes how to upgrade yo ur Zx1 rack-mount workstation by adding or replacing system components.

WARNING This is a user-serviceable system. Service and upgrade tasks should be

performed by users who can follow instructions in a manual to service equipment, and can do so without harm to themselves or damage to the equipment.

Before You Begin

WARNING The system is always on when connected to AC power. Before opening the

system, disconnect the system’s power cord from its AC power outlet.

WARNING Internal components may be at high temperatures. Allow time for them to cool

before handling them.

WARNING Internal components can be damaged by static electricity. Use an antistatic

wrist strap connected to the bare metal of the system’s chassis to protect against electrostatic discharge.

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

See Chapter 1, “Gaining Access to System Components,” for details on opening the system and protecting against electrostatic discharge.

These procedures assume you have removed the cover from the system.

Adding Memory

You can add system memory to the computer by adding or replacing dual inline memory modules (DIMMs). The system board has four DIMM sockets that can hold up to 1 GB of error-correction code (ECC) 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.

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, and end with bank 3.

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

Memory size

Configuration (ECC)

128 MB 16 x 72 256 MB 32 x 72

Memory

Bank 0 Bank 1 Bank 2 Bank 3

128 MB 128 MB 256 MB 128 MB 128 MB 384 MB 128 MB 128 MB 128 MB 512 MB 128 MB 128 MB 128 MB 128 MB

256 MB 256 MB

1,024 MB 256 MB 256 MB 256 MB 256 MB

See Chapter 3, “Servicing the System,” for instructions to install a DIMM. See the System Board Manual for DIMM socket locations.

Upgrading Processors

You can upgrade a single-processor system by adding another processor. When higher-speed processors become available, you can upgrade one- or two-processor systems by replacing the existing processors with faster processors.

Processors are mounted in a retention module that surrounds the processor slots. See Chapter 3, “Servicing the System,” and the System Board Manual for information on replacing a processor or adding a new processor.

Follow these rules when adding or replacing processors: ♦ When adding a processor to a single-processor system, the new processor must be the same

speed as the existing processor.

♦ When replacing dual processors with faster processors, both processors must be the same

speed.

♦ After installing faster processors, you must reinstall Windows NT on the system to ensure

proper operation with the new processors.

Adding Expansion Cards

You can install Accelerated Graphics Port (AGP), Peripheral Component Interconnect (PCI), noncompliant PCI, Industry Standard Architecture (ISA), and Plug-n-Play (PnP) expansion cards in the system. See below for a general description of these types of cards.

♦ AGP cards are graphics controllers that use the dedicated AGP interface for graphics

acceleration. AGP cards c‘ontain configuration registers that define resource information to the system during startup. AGP cards do not require manual system configuration when

installing the card. The system’s BIOS detects the board’s presence during startup and reads information from the board’s configuration registers to assign the necessary system resources.

♦ PCI cards contain configur ation registers t hat define resource information to the system during

startup. PCI cards do not require manual system configuration when installing the card. The system’s BIOS detects the board’s presence during startup and reads information from the board’s configur ation registers to assign the nec essary system resources.

♦ Non-compliant PCI cards 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 system’s BIOS to assign system resources before installing the card.

♦ Non-PnP ISA cards do not contain registers that define the resource information to the system

during startup. Therefore, you must configure the system’s 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’s BIOS automatically detects the installed card and assigns the necessary system resources. Since a PnP card is ISA-based, you install it in an 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 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 system board has seven expansion card slots, located at the lower-left corner of the system board. Slot 6 is a shared slot; you can install a PCI card or an ISA card in this slot, but not both.

Slot 1 - AGP

Slot 2 - PCI

Slot 3 - PCI

Slot 4 - PCI

Slot 5 - PCI

Slot 6 - PCI (shared)

Slot 6 - ISA (shared)

Slot 7 - ISA

See the System Board Manual for detailed information on the system board’s expansion slots.

Installing Expansion Cards

See the documentation that came with the card for details on installation, configuration, cable connections, and operation.

To install an expansion card:

WARNING The system is always on when connected to AC power. Before performing this

task, disconnect the system’s power cord from its AC power outlet.

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 3, “Servicing the System.”

2. Remove the expansion card from its antistatic packaging.

3. Slide the expansion card carefully into the card guides. Ensure that the connectors on the

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

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

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

6. Install the retaining screw.

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

Assigning System Resources

Some expansion cards include a configuration diskette that you can use to reserve the system resources required for the card. Other expansion cards do not include a diskette, but require that you manually program the BIOS with the configuration information.

See System Setup for details on a ssigning system resources and c onfiguring the BIOS for expansion cards.

Adding Disk Drives to the Disk Drive Bay

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

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

See Chapter 3, “Servicing the System,” or System Setup for information on installing JBOD or RAID disk drives in the disk drive bay.

Adding an Internal Peripheral Device

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

The following describes the devices in the peripheral device bay.

Drive

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

Type Maximum Bay Capacity

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 Cards” 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.

To install a device in the available peripheral device bay:

WARNING The system is always on when connected to AC power. Before performing this

task, disconnect the system’s power cord from its AC power outlet.

1. Open the face panel.

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

bay.

Locking Plate Thumb Screw

3. Lift the locking plate.

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

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

details):

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

− Disable termination on the new drive.

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

6. Do one of the following:

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

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

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

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

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

7. Do one of the following:

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

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

lower the locking plate.

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

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

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

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

drive.

Adding External SCSI Peripheral Devices

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

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 Lengths and Device Speeds

For each SCSI bus, the type of bus and the data clock speed of the fastest device on that bus determine its maximum length. Knowing this, you can determine the maximum cable length you can use to connect external SCSI devices to the system.

The following table provides a guide to maximum SCSI bus length. Note that bus width (for example, Narrow versus Wide) does not affect the maximum bus length.

Fastest device on the bus

Single-ended bus Differential bus LVDS bus

5 MHz (SCSI-1) 19.7 ft / 6 m 82 ft / 25 m 39.4 ft / 12 m 10 MHz (SCSI-2 or Fast) 9.8 ft / 3 m 82 ft / 25 m 39.4 ft / 12 m 20 MHz (Ultra or Fast20) 4.9 ft / 1.5 m 39.4 ft / 12 m 39.4 ft / 12 m 40 MHz (Ultra2 or Fast40) * Not recommended Not specified 39.4 ft / 12 m

* Bus used in the system

The total cable length on the system’s Wide Ultra2 SCSI bus is the sum of the following:

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

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

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

SCSI cable between the system and the first device

SCSI cable between each device

The maximum speed of a SCSI bus is limited to the speed of the slowest device on that bus.

SCSI Cable Quality Guidelines

To ensure data integrity and optimum performance, do the following:

♦ Use the shortest cables possible to connect SCSI devices to the system and to each other. ♦ Use high-quality SCSI cables to ensure adequate shielding.

CAUTION When handling cables, flex them as little as possible. Ensure that cables do not

contact sharp metal surfaces or become excessively bent or twisted. In particular, SCSI cables should not have any creased bends.

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

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 d evice 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.

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. J14 is used to daisy-chain multiple backplanes.

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

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

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

Jumper Settings

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

Disk Drive LEDs

Light-emitting diodes (LEDs) D1 through D8 are visual activity and status indic ators 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.

Drive Status LEDs

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

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

Left LED Activity

Off No error Steady on Disk drive rebuild stopped or disk drive is faulty Steady blink (approx. 1 per second) Disk drive rebuild in progress Fast steady blink (approx. 3 per second) Disk dr ive 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.

RAID Disk Drive Status

Power Supply

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

The power supply has the following DC output specifications.
