1 Accessing the Components

This chapter describes how to access the internal components of the system so you can service and upgrade an InterServe 800 SL system. It also describes methods for avoiding electrostatic discharge and closing the base unit.

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.

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

Avoiding Electrostatic Discharge......................................................................................... 2

Opening the Base Unit......................................................................................................... 2

Closing the Base Unit .......................................................................................................... 5

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 the system’s internal components.

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 The system produces high-leakage current. Flip the circuit breaker (if included) to the OFF

position when servicing or upgrading the base unit.

Tools are not required to remove the side panels because twist locks secure the panels to the unit. The following table shows which panel to remove to access the internal components.

Panel

Components

Right side System board, memory, processors, main cooling fans Left side AC section for redundant power supply only Both CD-ROM drive, floppy disk (or combo) drive, power distributions board

assembly; 5.25-inch option devices, LCD board, RAID section

CAUTION Use caution to avoid injury when removing side panels and other hardware.

NOTE Side panel removal is necessary for removal and replacement of the fixed mount 300 Watt

power supply. The redundant 550 Watt power supplies can be removed without taking off either panel.

WARNING For stand-alone racks, ensure the rack’s front and side stabilizers are extended at all

times.

To open the base unit:

1. Defeat the system’s intruder alert. See System Setup for more information.

2. Log off and shut down the operating system.

3. If your system contains two 550 Watt power supplies, flip the circuit breaker switch to the OFF position.

If your system contains a 300 Watt power supply, turn the keyswitch to OFF and remove the AC power cord before performing any service operations. Systems configured with the 300 Watt power supply do not have a circuit breaker.

4. If the base unit is in a rack and uses Intergraph sliding shelves, slide the unit out of the rack.

WARNING For base units installed in a standalone rack, ensure the rack’s front and side

stabilizers are extended at all times. If the rack includes adjustable feet on the stabilizers, they must be in full contact with the floor. If the rack includes locking casters, they should be locked.

−

Remove the screw (located under the sliding shelf handle) securing the sliding shelf to the rack.

−

Disengage the sliding shelf by lifting the release lever.

−

Pull the shelf out until it locks in the extended position. The back of the base unit should clear the front of the rack by two inches. You may need to disconnect cables to fully extend the unit.

−

The base unit can remain on the shelf during the servicing or upgrade procedures.

5. Locate the twist locks on the back of the base unit. Turn the locks counter-clockwise to disengage the side panels.

6. Pull the side panels back an inch then lift them off the unit. Figures on the following page show internal views of the system.

Right panel removed

Left panel removed

7. Before performing the service or upgrade procedure, review the section “Avoiding Electrostatic Discharge.”

Closing the Base Unit

CAUTION After servicing or upgrading the system, always replace the panels that were removed. The

panels 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. The system will not start unless the panels are properly replaced.

To close the base unit:

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

2. Replace the side panels and turn the twist locks clockwise to lock the panels into place.

3. If the unit is rack-mounted:

−

Unlock the sliding shelf by pressing the release tab.

−

Push the base unit into the rack until it fully retracts and locks into place.

−

Secure the sliding shelf by installing the screw under the sliding shelf handle.

2. Remove the heat-sink lock from within the heat-sink fins, if necessary, by pressing the

ends of the lock inward and pulling outward.

Heat-sink lock

3. Press the locking tabs on the top corners of the processor module inward, towards each

other, until they click into the release position.

4. Slide the processor module out of the retension module.

5. Remove the new processor module and heat sink from its antistatic package, and align

the processor module over the retension module. The processor module is keyed and fits only one way.

6. Press the processor module down until it seats.

7. Press the processor module locking tabs outward until they click into the locked

position.

8. Install the heat-sink lock between the heat-sink fins, if necessary, by sliding the lock

between the fins and pressing it onto the heat-sink lock mounting posts.

9. Install the fan duct assembly, ensuring that the fan power cable is attached to the same

connector on the motherboard as original installation. Secure in place with the four screws removed earlier.

Heat-Sink Mounting Brackets

Pentium II processors equipped with heat-sink fins use heat-sink locks fastened to mounting brackets to secure them to the system board, providing additional stability to the processor

module. See the system board diagram in Chapter 5, “System Board,” for connector and socket locations.

To replace a heat-sink mounting bracket:

1. Remove the processor module. See the “Processor Modules” section above for details.

2. Note the location and orientation of all cables connected to the system board and plug-in

cards. Disconnect the cables and remove all cards installed in the motherboard. Place the cards on an anti-static surface.

3. Remove the screws securing the system board to the chassis, including the jack screws

securing the ports to the I/O panel. Support the system board during removal of the last screws to prevent damage to the system board or the chassis.

4. Two mounting locks on the rear side of the system board secure the mounting bracket.

Remove these locks, and then remove the mounting bracket from the system board.

5. The heat-sink mounting bracket has two pins on the bottom and four pins on the top.

The bottom two pins are of different sizes. The size of the pins and the holes in the system board determine the correct orientation.

Insert the new heat-sink mounting bracket into the appropriate holes on the system board. The bracket will click when it is correctly inserted. Ensure the four top pins are closest to the processor slot.

6. Lock the heat-sink mounting bracket to the system board by inserting the two mounting

locks into the pins of the heat-sink mounting bracket, which are below the system board. The locks will click when they are securely fastened.

7. Install the system board in the chassis, securing the I/O ports and main system board

support screws.

8. Install the plug-in cards removed ealier. Connect all cables disconnected earlier,

ensuring that connector orientation and locations are correct.

Retension Modules

Pentium II processors are secured to the system board using retension modules. See the

system board diagram in Chapter 5, “System Board,” for connector and socket locations.

NOTE You do not need to replace a retension module to replace a processor module.

Retension module

To replace a retension module:

1. Remove the processor module. See the “Processor Modules” section above for details.

2. Remove the heat-sink locks, if necessary. See the “Heat-Sink Mounting Brackets”

section above for details. See the “Heat-Sink Mounting Brackets” section above for instructions on removal of system board.

3. Remove the screws securing the retension module to the system board, and remove the

retension module. There is a bracket containing studs that the retension module attaches to which mounts from the back side of the system board. This bracket will be loose and free to fall out of the holes in the system board as soon as the last screw securing the retension module is loosened.

4. Locate the key pin on one end of the processor slot on the board. Carefully line up the

key notch on the new retention module with the key pin on the processor slot. The key pin on the processor slot indicates the correct orientation of the CPU.

Lithium (CMOS/Clock) Battery

The lithium battery is located near the top left corner of the system board. See the system

board diagram in Chapter 5, “System Board,” for details. When you remove the battery, the system will lose its operating parameters stored in CMOS. As a result, the system BIOS parameters are lost.

Before removing the battery, start the system and enter BIOS Setup. Page through all the screens, making note of all parameters. Parameters include date, time, hardware configuration, and other data.

CAUTION Do not change any parameters. Doing so could cause your system to operate improperly or

not at all. After replacing the battery, you will need these BIOS parameters to ensure the system is restored to its previous state.

After you install the new battery, you must reset the date and time and reconfigure the BIOS. See System Setup for details on updating and configuring the BIOS.

WARNING There is a danger of explosion if the battery is incorrectly replaced.

WARNING Replace the battery with the same or equivalent type only, as recommended by the

battery manufacturer. Dispose of used batteries according to the battery manufacturer’s instructions.

To replace the battery:

1. Remove any option cards that restrict access to the battery. See “Option Cards” in this chapter for details.

2. Note the positive orientation of the battery. Carefully remove the discharged battery by grasping it firmly and pulling it out of the socket.

Preparing to Upgrade the System

Obey all warning and caution labels while replacing parts. The procedures in this chapter assume you have opened the unit to access the internal components. After you have finished

servicing the system, close the unit as described in Chapter 1, “Accessing the Components.”

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.

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.

CAUTION The system produces high-leakage current. Flip the circuit breaker (if included) to the OFF

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 installation.

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 processors) 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.

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

Memory size

Configuration (ECC)

64 MB 8 MB x 72 128 MB 16 MB x 72 256 MB 32 MB x 72 registered

NOTE The 32 MB x 72 registered DIMM cannot be mixed with any other type of DIMM.

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. Processors are mounted in a processor retention module which surrounds the processor slots. See the system board figures in Chapter 5, “System Board,” for the location of processor slots and related connectors.

You can upgrade to dual processors in the following ways:

You can purchase a single-to-dual processor upgrade kit from Intergraph Computer Systems. The kit contains all the hardware, software, and documentation required to perform the upgrade.

You can purchase a second processor from another vendor.

After completing the hardware upgrade, you must also upgrade to a multi-processor version of Windows NT. You can upgrade the operating system in the following ways:

You can purchase the Intergraph upgrade kit mentioned previously. The kit contains all the hardware, software, and documentation required to perform the upgrade.

If you have or purchase a Windows NT 4.0 Workstation Resource Kit (ISBN 1-57231-

343-9), you can use software on the kit’s CD-ROM to upgrade Windows NT 4.0. The files required for the upgrade are

While not recommended by Intergraph Computer Systems, you can back up all critical

UPTOMP.EXE , UPTOMP.INF, and UPTOMP.TXT.

system data, install the second processor, and reinstall Windows NT 4.0 to load the required multi-processor Hardware Abstraction Layer (HAL).

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 terminator car d

2. 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 retension module.

3. Press straight down and apply even pressure at both ends of the CPU module until it seats. The retension module is keyed to ensure proper insertion.

4. Press the processor module locking tabs outward until they click into the locked position.

5. 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, “Replacing System Components,” for details.

Adding Option 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 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 expansion cards sold by Intergraph Computer Systems fully comply with the

Peripheral Component Interconnect Specification, 2.1.

Non-compliant PCI cards mechanically comply with the 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” 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 125 watts. The PCI slots are limited to 25 watts power dissipation per the Peripheral Component Interconnect Specification, 2.1 .

Option Card Slot Locations

The option slots are located at the top right section of the system board, as shown in the following figure. The top PCI slot (shared) shares space with the ISA slot. You can install a card in the top PCI slot, or in the ISA slot, but not in both.

ISA Slot (shared)

PCI Slot (shared)

PCI Slot

AGP Slot

NOTE The shared PCI slot does not support bus-mastering PCI cards.

Upgrading Graphics Cards

Several graphics cards, for example the Matrox G100, are available for InterServe 800 SL.

See Chapter 7, “System Specifications,” for details. Due to the limited number of PCI slots available, it is recommended that only AGP video cards be used in the InterServe 800 SL.

Intergraph Computer Systems installs the graphics card into the AGP slot J1 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. Remove the right side panel as described in Chapter 1, “Accessing the Components.”

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 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.

9. Install the right side panel 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 System Setup for details on assigning system resources and configuring the BIOS for option cards, and for a list of available system address resources (DMA, I/O, memory) and related details.

NOTE Treat non-compliant PCI cards and PCMCIA cards as ISA cards for assigning system

resources.

Adding Devices

The system provides a dual-channel Wide Ultra SCSI-3 controller for support of 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.

JBOD systems provide either 4 or 8 (depending on configuration ordered) 3.5-inch x

1.6-inch internal bays for system or optional disks.

RAID systems provide 8 each 3.5-inch x 1.6-inch internal bays.

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, 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 “Installing Option Cards” for details.

If you are installing a device with an EIDE interface, it must be mounted in one of the external drive bays only. You must also install a new EIDE control cable for your device.

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.

Device Bays

You can add optional mass storage devices to the internal and external drive bays. The following shows bays 1 through 12.

Bay 12, Floppy Drive Bay 11, EIDE CD-ROM Drive

Bay 10 Bay 9

Bay 8

Bay 7

Bay 6

Bay 5

Bay 4

Bay 3

Bay 2 Bay 1, System Drive

The floppy, EIDE CD-ROM, and system drives are standard; other devices are available as options. Numbering of the drive bays for both JBOD and RAID starts from the bottom.

NOTE RAID system is shown in figure; JBOD system drive area is slightly different.

The following table provides the device locations and related information.

NOTE If you are installing an additional EIDE device, you must mount the device in Bay 9 or 10 and

install an additional EIDE control cable due to cabling restrictions.

Installing Dev ices in the Drive Bays

NOTE Two internal bay drive brackets are installed in the chassis for mounting drives.

To install a drive in the external drive bay:

1. Turn off the ciruit breaker and remove the AC power cord from the system.

2. Remove both side panels.

3. Remove the four screws that secure the external bay disk drive tray to the chassis. There are two hex head screws on the right side, and two phillips head screws on the left side.

External Bay Mounting Screws (4)

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

5. If installing an IDE device, go to step 6. 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.

−

Go to Step 7.

6. If you are installing an IDE device, set the proper Master, Master with slave present, or Slave setting, and continue with 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 1.6-inch device, such as a tape drive or a CD writer, remove the mounting guide from the drive tray and attach the guide to the right side of the device. See the following figure.

8. Do one of the following:

−

Slide the tray assembly with standard disk drive into the chassis, align the mounting holes, and install the screws

−

Slide the 1.6-inch device into the chassis, align the mounting holes, and install the screws

9. Connect the proper interface cable (either SCSI or EIDE) and the power cable to the disk drive. Power cables for drives added to the external drive bays are clipped in the bottom of the chassis on the left side.

To install a drive in an internal bay (JBOD only):

1. Remove the right and left panels. See Chapter 1, “Accessing the Components,” for details.

2. Open the disk area door.

3. Remove the screws that secure the drive bay blanking plate to the front of the chassis.

4. Do all of the following:

−

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

−

Disable termination on the new drive

See Chapter 6, “Peripherals,” for details on these tasks.

5. Slide the drive into the JBOD housing in the next available opening from the bottom of the drive bay.

6. Install 4 screws (two on each side) to secure the drive to the JBOD housing.

7. Connect power and SCSI controller cables to the new drive.

8. Replace the drive bay blanking plate.

9. Close the disk area door and install the side panels.

Adding External SCSI Drives

You can add single-ended external SCSI drives to the system by connecting them to the optional Ultra SCSI port on the back of the system. A Wide Ultra SCSI external port is also optional and requires the purchase of an additional Wide Ultra SCSI controller. See “External Ports” in Chapter 5, for an illustration of port locations.

You can also install additional SCSI expansion cards (adapters) to support external 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, the primary adapter included with the InterServe 800 SL.

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

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 for boot device) uses ID 0

SCSI host bus adapter always uses ID 7

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

4 mm DAT 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:

Disable termination for all devices that are connected to the Ultra-Wide SCSI bus inside the chassis; the SCSI cable for that bus has an active terminator installed when shipped from Intergraph Computer Systems.

Enable termination on the last external drive on the SCSI cable chain, using only an active terminator.

Disable termination on all other external drives on the SCSI cable chain.

Connecting the External SCSI Drive

To add an external SCSI drive:

1. Connect one end of the external SCSI cable to one of the following external ports:

−

The optional Ultra SCSI port. It is located on one of the cards installed in the I/O panel and is available only when ordered as an option at the time the system is originally purchaed.

−

The optional Wide Ultra SCSI port. It is located on one of the cards installed in the I/O panel and is available only when ordered as an option at the time the system is originally purchased.

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” earlier

in this chapter for details.

4. Do one of the following:

−

If the device is the last or only device on the SCSI chain, enable active SCSI termination

−

If the device is not the last or only 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 system configuration, or the capabilities of SCSI devices connected to the 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.

Disabling SCSI Sync Negotiation

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

To disable sync negotiation:

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

2. From the SYSUTIL main menu, select SCSI Select Utility.

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

4. Select the SCSI Device Configuration option.

5. Change the Initiate Sync Negotiation values for all the attached SCSI devices (represented by their SCSI ID number) to no.

6. Set the Maximum Sync Transfer Rate values for the devices to the desired settings. If changing these settings to extend cable lengths or add more devices, set Ultra SCSI devices to 10.0 or less.

NOTE The Advanced Configuration Option allows you to disable the Ultra SCSI controller. When

Ultra SCSI is enabled, the available sync rates are 20, 16, 13.4, 10. When Ultra SCSI is disabled then 10, 8, 6.7, 5 are available.

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

8. Press any key to restart the system.

LCD Board (MSMT510)

The LCD board consists of a four-line display screen, soft-touch buttons, and status LEDs that allow you to monitor the chassis (and the disk section, if RAID). The screen reports various status and events in a software-independent manner. The InterServe 800 SL power supplies feature a +5V output -- which is always on -- to report the system status even if the system is powered off.

The LCD board functions as a central resource through which system power and status signals are routed. The system monitor accepts status inputs from the dual 550 Watt power supplies, internal RAID disk section, temperature sensors, safety interlocks, and fans, and generates the appropriate alarms and alerts.

NOTE If the microcontroller of the LCD board fails, it will not issue a command to the power

supplies to turn-on when the keyswitch is moved to the on (|) position. The LCD board will not display any text on the LCD screen, and should be replaced.

The following diagram illustrates the routing of signals used to collect and report status through the microcontroller.

Channel Module

The disk section uses the dual-channel module (MSMT456) to enable two channels for the RAID disk section.

SAF-TE Card

The SAF-TE card (MSMT460) is the primary component that makes the disk section a RAID-capable subsystem.

Jumper Settings

NOTE RAID systems, which use the AMI RAID controller, do not use any jumpers on these headers.

The spin-up delay and SCSI ID setttings are controlled by the RAID controller and SAF-TE card, respectively.

Power Supplies

Two power supply options are available, as follows:

Single 300 Watt power supply (MPWS175)

Dual 550 Watt power supplies (MPWS139)

300 Watt Power Supply (MPWS175)

MPWS175 is a 300 Watt power supply with 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.

Nominal Output Voltages Maximum Current Rating

The footnotes are defined as follows.

1. Standby +5.0 VDC output voltage is always on

2. Maximum +5.0 V and +3.3 V combined power is 250W

The power supply has two DC output connectors that attaches to J18 and J19 on the power distribution board. The connector pinout for J18 follows.

550 Watt Power Supplies (MPWS139)

If the system is equipped with two 550 Watt power supplies (MPWS139), these power supplies are hot-swappable and offer 1+1 redundancy. Each power supply has six outputs and autoranges between 90-132 VAC and 180-264 VAC. The input frequency range for each power supply is 47-63 Hz, single phase. Input current is 5.5 amps maximum for the 115 VAC range and 2.75 amps for the 230 VAC range.

The current is equally shared (within +10%) by the two power supplies at maximum load. If one power supply fails, the remaining power supply takes over. All outputs have seriesblocking diodes to prevent an output fault in one power supply from pulling down the outputs of the other power supply. At full load, the power supply has a minimum efficiency of 65 percent. Each power supply is enclosed in a case that includes two fans to provide additional airflow through the system.

The power supply has the following DC output specifications.

Temperature Sensor and Fans

An ambient temperature sensor is located on the LCD board. To provide air flow through the system, the system uses up to four chassis fans (CFAN123), depending on the power supply option ordered. If hot swap power supplies are ordered, the system will have three chassis fans. The chassis fans are RPM-reporting so their status is available on the LCD screen. The fans enclosed in the 550 Watt power supply housing are also RPM-reporting. The fan enclosed in the 300 Watt power supply housing is not an RPM-reporting fan. There is also a processor cooling fan mounted directly above the processor(s).

Processor Fan

The chassis fan is field replaceable. See Chapter 2, “Replacing System Components,” for details on replacing the chassis fan. Ensure that you install the fan with the airflow direction arrow pointing toward the inside of the chassis. The following figure shows the side view of the fan and the arrows to indicate airflow direction and rotation.

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 PCI interrupt register enables (Low) or disables (High) the routing of the PCI interrupt to an ISA interrupt. The lowest four bits (3:0) of each PCI interrupt register determines to which ISA interrupt the PCI interrupt is routed. You can map the PCI interrupts 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: INT A, INT B, INT C, and INT D. These are connected to the PCI interrupts, PIRQ0 through PIRQ3 as shown below:

Serial

The Serial ports (also referred to as RS-232 asynchronous communications ports, or COM ports) connect modems, printers, peripherals, and other computers to the system. The serial ports (labeled 1 and 2) are 9-pin, male DB9 connectors. If connecting a serial device with a 25-pin DB25 connector, use a 25-pin to 9-pin adapter cable to mate with the serial port on the system. Use only shielded cables with the serial ports.

Universal Serial Bus 1 and 2

The Universal Serial Bus (USB) port connects USB devices to the computer. These devices can include printers, keyboards and other peripherals that have historically used serial, parallel, mouse, and keyboard I/O buses. USB devices, designed to be fully Plug-andPlay (PnP), feature hot attach/detach and daisy-chain capabilities. The USB port can transfer data at a maximum theoretical rate of 12 megabits per second.
