1 Accessing the System

This chapter describes how to access the internal components of the system so you can service and upgrade an InterServe 8000 server.

Before You Begin

WARNING Heed all warnings and cautions in the accessing, servicing and upgrading instructions.

Personal injury and damage to equipment can occur if documented procedures are not followed.

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

when servicing or upgrading the base unit.

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

discharge (ESD). ESD can damage components inside the system.

Opening the Base Unit

The system contains safety interlock switches that turn the system power off when you remove a side panel (in systems with 550 Watt power supplies) or the power supply cover (in systems with 539 Watt power supply). You do not have to manually power off the system before servicing, but you must log off and shut down the operating system to preserve data on the disk drives.

The side panels are secured using twist locks on the back of the unit, so you need no tools to remove them. The following table shows which panel to remove to access the internal components. The right side and left side are as viewed from the front of the system.

Right Side Panel

I/O Connector Board Processor Board CD-ROM Drive I/O Expansion Panel Memory Floppy Disk (or Combo) Drive AC Section Processors Power Distribution Board Assembly

NOTE The power supplies and disk drives can be removed without taking off the side panels.

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

LCD Board RAID Section

WARNING For 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.

To open the base unit:

1. Defeat the system’s intruder alert. See the System Setup document delivered with the system for

more information.

2. Log off and shut down the operating system.

3. Flip the circuit breaker switch to the OFF position.

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

−

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 rear 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.

WARNING For 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.

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. The system power turns off

automatically when either side panel is removed. Figures on the following pages show internal views of the system.

Discharge.”

The following figure shows the system with the left side panel removed (processor board side).

The following figure shows the system with the right side panel removed (I/O expansion board side).

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.

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 Replacing System Components

This chapter describes how to replace system components in an InterServe 8000 server.

Before You Begin

Follow the instructions in Chapter 1 for opening the unit to access the internal components.

Before replacing parts, ensure the problem has been correctly identified so that you do not inadvertently replace a properly working part. The troubleshooting chapter in the System Setup document delivered with the system has a list of potential problems and errors your system may exhibit.

WARNING Heed all warnings and cautions in the accessing, servicing and upgrading instructions.

Personal injury and damage to equipment can occur if documented procedures are not followed.

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

when servicing or upgrading the base unit.

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

discharge (ESD). ESD can damage components inside the system.

Lithium Battery

The Lithium battery on the processor board can be replaced if it fails. Once you remove the battery, the system will lose its operating parameters stored in CMOS. As a result, the system BIOS parameters are lost. After installing the new battery, you must reset the date and time and reconfigure the BIOS. See the System Setup document delivered with the system for details on 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 the left side panel.

2. Locate the battery near the memory sockets J45 - J48.

3. Note the positive orientation of the battery. Carefully remove the discharged battery by grasping it

firmly and pulling it out of the socket.

4. Install the new battery in the same orientation as the old battery.

5. Dispose of the battery according to the manufacturer’s instructions.

6. Install the option cards that you removed.

3 Upgrading the System

This chapter describes how to upgrade an InterServe 8000 server by adding memory, adding processors, converting from non-RAID to RAID, adding option boards, and adding SCSI drives.

Before You Begin

Follow the instructions in Chapter 1 for opening the unit to access the internal components.

WARNING Heed all warnings and cautions in the accessing, servicing and upgrading instructions.

Personal injury and damage to equipment can occur if documented procedures are not followed.

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

when servicing or upgrading the base unit.

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

discharge (ESD). ESD can damage components inside the system.

Adding Memory

The following memory kits are available for adding memory to the system. Each memory kit contains four SIMMs and a disposable antistatic wrist strap.

Kit Number

FMEM149 16 MB (4Mx36) 64 MB FMEM150 32 MB (8Mx36) 128 MB FMEM151 64 MB (16Mx36) 256 MB

The following table defines the InterServe 8000 memory upgrades.

Base Memory

64 MB 64 MB 128 MB 512 MB 128 MB 128 MB 256 MB 1 GB 256 MB 256 MB 512 MB 2 GB

NOTE Base memory uses four SIMMs. The first upgrade adds four SIMMs, and subsequent upgrades add

eight SIMMs (two upgrade kits).

CAUTION System memory modules available from Intergraph have been certified for use with Intergraph

computers at extremes of temperature and system load to ensure reliable performance. System memory modules available from other vendors may not function properly or reliably in your Intergraph computer.

Size of Each SIMM Total Upgrade Size

First Upgrade Subsequent Upgrades Maximum Memory

All SIMMs must be the same size and the banks must be filled sequentially. The following figure shows the bank layout. Individual sockets are labeled J21 through J52 from left to right. Base memory for InterServe 8000 systems is installed in sockets J35, J36, J39 and J40 of Bank 0.

J40 J44 J48 J52J21 J25 J29 J33

Bank 3

Bank 2

Bank 0 Bank 0Bank 1 Bank 1

To avoid damaging the SIMMs, take the following precautions.

Do not bend, twist, drop, or otherwise handle the SIMMs carelessly.

Do not expose the SIMMs to moisture or extreme temperatures.

Do not remove the SIMMs from the antistatic bag until installation.

To install memory:

1. Remove the left side panel. The following figure shows the memory sockets on the processor

board.

Available

Sockets

Base

Memory

Available

Sockets

2. Examine the sockets and become familiar with the layout as shown in the figure above.

3. Remove all installed SIMMs (memory modules).

4. Starting from the outer socket of the last bank to be populated, install a SIMM at an angle (leaning

towards the center of the board) and push the SIMM up. Ensure the metal socket tabs engage the SIMM. Repeat for every SIMM, installing the next SIMM into the socket closer to the center of the board.

For example, if your InterServe system has minimum memory (four SIMMs), and you are adding

three Intergraph memory kits (12 SIMMs total), install the first two SIMMs in sockets J29 and J44 of Bank 1, then work towards the center of the board.

5. Close the base unit and restart the system. The total installed memory displays during Windows

NT boot up.

NOTE If the total expected memory does not display, ensure all the SIMMs are installed in the correct sockets

and fully seated in the sockets. If the SIMMs are properly installed, then one or more SIMMs are faulty. Obtain replacement SIMMs.

Adding Processors

The system supports up to four processors on the processor board. All four sockets are Zero Insertion Force (ZIF) type that meet Overdrive Socket 8 specification.

Each processor upgrade kit from Intergraph includes two processors (with heat sink attached to each), two Voltage Regulator Modules (VRMs), two metal clips, and a disposable antistatic wrist strap. Follow these instructions to install the upgrade.

To upgrade the processors:

1. Remove the left side panel. Examine the existing processors and VRMs to see how they fit into

their sockets. Note the metal clip securing the processor heat sinks.

Voltage Regulator Module Sockets

Processor Sockets

2. Raise the levers on the two empty processor sockets.

3. Install the processors into the sockets. The pins on the bottom of the processors are arranged to

ensure proper insertion into the socket.

4. Attach the metal clip to each processor and heat sink. Both ends of the clip must engage the socket

tabs.

5. Install the VRMs into their sockets. Press the VRM evenly and firmly. When properly installed,

the socket tabs will hook over the notches inside of the VRM.

6. Close the base unit and restart the system. The number of installed processors displays at the blue

Windows NT boot screen.

NOTE If the new processors do not display, ensure the VRMs and processors are fully seated in their sockets.

Converting a Non-RAID System to RAID

If your system uses non-RAID disk drives, you can convert it to use RAID drives by swapping the nonRAID components with their RAID counterparts.

To convert a non-RAID system to RAID:

1. Remove the right side panel.

2. Disconnect the two SCSI cables from the UW SCSI controller.

UW SCSI Controller

SCSI Cables

3. Remove the UW SCSI controller.

4. Install AMI RAID controller in slot previously occupied by the UW SCSI controller.

5. Connect the SCSI cables from the disk section to the RAID controller. The cable attached to CH 0

on the disk section must connect to CH 0 on the RAID controller (and the same for CH 1).

6. Install the SAF-TE card into the top slot of the disk section. Slide the card along the rails, and

push slowly but firmly until the card fully seats in the connector.

9. Close the base unit and restart the system.

10. Install the InterRAID software and configure the drives for RAID use. Refer to the InterRAID

documentation included with the upgrade kit.

Adding Option Boards

This section describes how to install option boards and assign system resources if the option board requires special assignments. The following paragraphs summarize the design of Peripheral Component Interconnect (PCI), non-compliant PCI, Industry Standard Architecture (ISA), and Plug-nPlay (PnP) option boards.

Jumpers OffJumpers On

PCI boards contain configuration registers that define resource information to the system during startup. PCI boards do not require manual system configuration when installing the board. 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. The system’s PCI slots are limited to 25 Watts power dissipation per the Peripheral Component Interconnect Specification. Installed PCI boards must draw less than 25 Watts of power. Also, the total power consumed by all PCI boards in the system should be less than 180 Watts.

Non-compliant PCI boards mechanically comply with the Peripheral Component Interconnect Specification, but do not contain configuration registers that allow the system to automatically

assign the necessary resources. These boards install in PCI slots, but you assign system resources manually (using AMIBIOS Setup) before installing the board. In this regard, they are like ISA boards, as described below.

ISA boards do not contain registers that define the resource information to the system during startup. Therefore, you must run the AMIBIOS Setup to define the board to the system before installing the ISA board. This reserves system resources for the board and prevents conflicts with ISA option boards already installed. Refer to “Assigning System Resources for Option Boards” in the System Setup.

PnP boards are ISA boards that contain configuration registers like PCI boards. During startup, the system BIOS automatically detects the installed board and assigns the necessary system resources. Since PnP boards are ISA-based boards, they must be installed in the ISA slots.

The following table shows the required and recommended slots for installing Intergraph option boards. All PCI option boards sold by Intergraph fully comply with the Peripheral Component Interconnect

Specification, 2.1.

NOTE The RAID controller is included in the kits for InterRAID-8e expansion disk array cabinets.

To install option boards:

NOTE Assign system resources for ISA and non-compliant PCI boards before installation. Refer to th e

section, “Assigning System Resources for Option Boards” in the System Setup.

1. Remove the right side panel as described in Chapter 1.

2. Using a quarter-inch nutdriver, remove the screw and blanking plate from an available slot.

3. Install the option board. Press firmly to ensure the board seats completely into the slot.

4. Connect the required external cables to the option board.

5. Secure the board to the chassis using the screw removed in step 2.

6. Close the base unit.

7. Restart the system, and note the special information about ISA boards, PnP boards, and the

InterSite Server Monitor card.

−

For ISA boards, refer to the System Setup document delivered with the system for information

about BIOS parameters that should be set.

− For PnP boards, notice when the following message displays: Hit DEL if you want to

run SETUP. Press

DELETE to run AMIBIOS Setup, and enable the “Boot to PnP Operating

System” parameter under PCI/PnP Setup menu. Exit AMIBIOS Setup and restart the system.

Refer to the System Setup document delivered with the system for instructions to use

AMIBIOS Setup.

−

For the InterSite Server Monitor card, the BIOS automatically assigns resources, which may

conflict with other ISA boards already installed in your system. If so, the message Static

Resource Conflict displays during bootup. Use AMIBIOS Setup to modify the “Server

Monitor” parameters in Chipset Setup menu so they do not conflict with other boards. Refer

to the System Setup document delivered with the system for instructions to use AMIBIOS

Setup.

Adding External SCSI Drives

You can add single-ended external SCSI devices to the system by connecting them to the SCSI port on the back of the base unit. Additional SCSI option boards (adapters) can be installed to support external SCSI devices as well. Refer to the “Adding Option Boards” section earlier in this chapter to install new boards.

Cable Length Requirements

InterServe 8000 systems are equipped with an Ultra SCSI controller (AIC 7860) for all internal and external SCSI devices. By default, the controller arbitrates with each device (that is, initiates sync negotiation) to determine the data rate the device will use to transfer data (5, 10, or 20 MHz). If the target device complies with the 20 MHz SCSI specification, then the data transfer rate will be 20 MHz. If another device complies with 10 MHz, then date transfer will be at 10 MHz without changing any settings for the controller or the target device.

The number of devices and length of the cables used to connect the devices becomes a factor when using Fast SCSI-2 or Ultra SCSI devices. Ultra-SCSI devices impose shorter cable restrictions than Fast SCSI-2 or SCSI-1. The total length of the SCSI cabling must not exceed the following:

Number of Devices

SCSI-1 Fast SCSI-2 Ultra SCSI

1 to 4 19.8 feet (6 meters) 9.9 feet (3 meters) 9.9 feet (3 meters) 5 to 7 9.9 feet (3 meters) 9.9 feet (3 meters) 4.9 feet (1.5 meters)

NOTE The SCSI controller (integrated or on an option board) counts as one device.

NOTE The AIC 7860 can be configured to transfer data at Fast SCSI-2 rates for all devices. This allows Ultra

SCSI devices to be installed without being hampered by the Ultra SCSI cable restrictions. Total cable

length can then be extended to the Fast SCSI-2 length. See “Disabling SCSI Sync Negotiation” later in this chapter to configure the controller.

When attaching drives to the system’s SCSI port on the I/O connector board, the total length of the SCSI cabling is the sum of all of the following:

SCSI bus trace length on I/O expansion board - 12.0 inches (30.5 cm)

SCSI cable inside the base unit - 41 inches (104 cm)

SCSI cable inside each device (average) - 8 inches (20 cm)

SCSI cable between the base unit and the first device

SCSI cable between each device

If attaching SCSI drives to an optional SCSI adapter, the total length of the SCSI cabling is the sum of all of the following:

SCSI bus trace length on the adapter (refer to vendor’s documentation)

SCSI cable inside each device (average) - 8 inches (20 cm)

SCSI cable between the base unit and the first device

SCSI cable between each device

Connecting the Device

To add an external SCSI device:

1. Connect the SCSI cable to the SCSI port on the base unit and to the device.

2. Set the device’s SCSI ID to an unused number (1, 2, 3, 5, or 6). By default, the following devices

use pre-defined SCSI IDs:

−

System disk drive uses ID 0.

−

CD-ROM drive uses ID 4.

−

SCSI bus uses ID 7.

3. Disable or enable the device’s SCSI termination according to the vendor’s instructions. The last

external device on the SCSI cable chain must have SCSI termination enabled. All other external devices must have SCSI termination disabled.

4. If necessary, install the device drivers and configure the device according to the vendor’s

instructions.

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.

Memory Subsystem

Components

The components that make up the memory subsystem include the Orion data path (OMC-DP), Orion data controller (OMC-DC), four memory interface chips (MICs), sockets, and memory modules.

The OMC-DP provides a consolidated memory data path between the P6 bus and the memory interface chips (MICs). The MICs provide the interface between the P6 bus (via the OMC-DP) and the installed

memory modules. Each MIC handles ¼ of the memory data path, and is optimized for interleaved performance using read-around writes and data buffering. The OMC-DC is an addressing and control device for the DRAM array that interfaces to the OMC-DP, MICs and the installed memory modules.

The sockets on the processor board accept 60 ns, fast page mode, 72 pin (parity pinout) single inline memory modules (SIMMs). The board has 32 SIMM sockets. There are four banks in the memory subsystem, each banks containing eight sockets. Three SIMM sizes are supported: 4Mx36 (16 MB), 8Mx36 (32 MB), and 16Mx36 (64 MB). Systems with base memory can be expanded as follows:

64 MB (four 4Mx36 SIMMs) -- expanded with 4Mx36 SIMMs up to 512 MB maximum memory.

128 MB (four 8Mx36 SIMMs) -- expanded with 8Mx36 SIMMs up to 1 GB maximum memory.

256 MB (four 16Mx36 SIMMs) -- expanded with 16Mx36 SIMMs up to 2 GB maximum memory.

Bank 0 is half-populated (four SIMMs) for base memory configurations (64 MB, 128 MB, or 256 MB). The first upgrade must fill the second half of Bank 0, and subsequent upgrades must completely fill each bank sequentially from Bank 1 to 3. All SIMMs in the memory subsystem must be the same size.

Memory Data

Memory data is organized into words, interleaves, and rows.

Each SIMM generates either the low word (bits 35 to 0) or the high word (bits 71 to 36) of a 72-bit doubleword (8 bits of which are ECC bits) depending on installed location. The low word and high word sections are split on each side of the board as shown in the following figure. The high word is called word 1 or W1, and the low word is called word 0 or W0. Due to the design, if a row in W0 is populated, the same row in W1 (and vice versa) must also be populated for proper operation. The same memory density SIMM must be used in the row.

Rows are numbered 0 through 7. Starting at the center of the board and moving out, the first 4 SIMMs on both sides are on row 0 (rows 0 and 1 if the SIMMs are double-sided). The next four SIMMs are on row 2 (and 3 if double-sided), and so on, through the last (outermost) four SIMMs on each side of the board, which are on row 6 (and 7 if double-sided).

Within each row there are four interleaves, designated i0 through i3. Base InterServe configurations populate i0 and i1 of Row 0/1 for two-way interleave. When upgrades are installed, all four interleaves of the adjacent rows are populated, yielding four-way interleave for all installed memory. The correlation between banks and rows is:

Bank

Rows Interleave

0 0/1 i0, i1, i2, i3 1 2/3 i0, i1, i2, i3 2 4/5 i0, i1, i2, i3 3 6/7 i0, i1, i2, i3

Bank 0 = Rows 0/1 Bank 2 = Rows 4/5 Bank 1 = Rows 2/3 Bank 3 = Rows 6/7

Rows 6/7Rows 4/5Rows 2/3

The following table shows the correlation between interleaves (ix), words (Wx), rows and the socket J numbers. The ECC Monitoring Utility, used to detect and diagnose memory problems, specifies SIMM locations by interleave and row, but does not distinguish which word the error occurred in. Refer to the ECC Monitoring Utility help for additional information.

i1 i2 i3

W1 W0 W1 W0 W1 W0 W1 W0 Row 0 Row 1 Row 2 Row 3 Row 4 Row 5 Row 6 Row 7

NOTE Since ECC Memory driver does not distinguish whether an error occurred in word 0 or word 1 of a

given interleave, both words (i.e. both SIMMs) have to be changed to correct a single-bit problem. For example, correcting single-bit errors that are occuring in interleave 0, row 0, requires replacing SIMMs in J36 and J40.

PCI Bridge

Two PCI bridge chips (Intel OPB 0 82454) provide high-bandwidth PCI compatibility for the system. One bridge chip supports PCI bus 0 (Primary Compatibility bus), and is the path by which processors have access to all PC compatibility devices such as the ISA bus, BIOS PROM, and graphics controller. PCI bus 0 supports slots 1 through 3. PCI bus 1 (Primary Auxiliary bus) is also bridged directly off the P6 bus by the second 82454 and supports PCI slots 4 through 7. For best system performance, highbandwidth devices that efficiently use PCI burst protocols to transfer data as bus masters should reside on PCI bus 0 or 1 (slots 1 through 7).

NOTE The remaining PCI slots (8 through 10) are supported by the DEC 21050 on the I/O expansion board.

Lithium Battery

The Lithium battery on the processor board provides power to the Real Time Clock, which the MSMT332 board uses to display the current time on the LCD screen. As long as the system is running, the batteries are not used to sustain the information. If the battery fails, the LCD screen will not display the date and time.

Component Descriptions

The I/O expansion board provides PCI and ISA expansion slots. It also has controllers for the graphics, non-RAID SCSI, mouse, keyboard, serial port, parallel port, and floppy. PC compatibility hardware (BIOS PROM, NVRAM, RTC) and interrupt logic are also located on the I/O expansion board.

Graphics Accelerator

The graphics accelerator (Matrox MGA-2064W) interfaces to the system board through the PCI bus. This accelerator supports all of the standard VGA graphics modes in addition to native modes capable of resolutions up to 1600 x 1200. The frame buffer interface is 64 bits wide and is clocked at 100 MHz. Color depths of 4, 8, 16, 24, and 32 bits are supported, allowing a resolution of 1280 x 1024 (24 bit color depth) in only 4 MB of frame buffer memory. Features such as bit block transfer (BitBlt), Line Draws, and Fills provide hardware acceleration for Windows. Video playback is accelerated through scaling and YUV to RGB color space conversion.

Palette DAC

The palette DAC operates up to 175 MHz and converts the digital RGB data in the frame buffer to analog signals for the monitor. The device includes two fully programmable phase-locked loop clock sources for both the memory clock and the pixel clock.

Window RAM

Window RAM (WRAM) is the video memory used by the MGA-2064W. The graphics frame buffer consists of two 256K x 32 WRAM components for 2 MB of video memory. WRAM is a dual-ported video memory specially designed to accommodate common drawing functions, offering higher graphics performance at a lower cost than standard Video RAM.

Starting with 2 MB WRAM, a 2 MB or 6 MB WRAM mezzanine module can be added for improved video performance. 8 MB of WRAM is the maximum amount configurable. Memory above 2 MB increases the number of colors available at each resolution, enabling you to work in true color mode at higher resolutions. Increased WRAM also improves color acceleration by providing extra caching memory for storing off-screen fonts and images.

SCSI Controller

The SCSI controller is the Adaptec Ultra SCSI Adapter (AIC-7860), which provides a single-ended bus for SCSI-1, Fast SCSI-2, and Ultra SCSI devices. The SCSI bus is dedicated to the hard disk drives and CD-ROM drive. The SCSI bus actively terminates on the system board and at the end of the internal SCSI cable. The AIC-7860 supports low-speed devices to allow legacy SCSI devices to be used with the system. By default, the controller functions in Fast SCSI-2 mode rather than Ultra mode.

Super I/O Controller

The I/O expansion board utilizes a Standard Microsystems Corporation (SMC) Super I/O Controller (FDC37C932) to integrate mouse, keyboard, serial, parallel (multi-mode), floppy (2.88 MB), and RealTime Clock (RTC) functions into one chip.

The FDC37C932 supports four serial ports via two external port connectors (COM 1 and COM 2). COM1 can be configured as COM1 or COM3; COM2 can be configured as COM2 or COM4. The serial ports use the system I/O addresses shown below.

Port

Addresses Interrupts

COM1 3F8-3FF IRQ4 COM2 2F8-2FF IRQ3 COM3 3E8-3EF IRQ4 COM4 2E8-2EF IRQ3

The addresses for each serial port can be configured in AMIBIOS Setup, as described in the System Setup. Do not assign more than one device to the same COM port number. Serial port problems occur because a serial port and another device are assigned to the same COM number. The system and the connected serial device must be set to the same communications parameters (baud rate, parity, number of data bits, and number of stop bits). Refer to the serial device documentation for information about setting these parameters.

The parallel port functionality of the FDC37C932 include the following modes:

Normal mode (or Compatibility mode) - an industry-standard parallel interface mode. Normal mode provides an asynchronous, byte-wide forward channel (host to peripheral), and is the base mode common to all compliant interfaces.

SPP mode (or Byte or Bi-Dir mode) - compatible with IBM PS/2 hosts. SPP is an asynchronous, byte-wide reverse channel (peripheral to host) mode using the eight data lines of the interface for data, and the control/status lines for handshaking. Transfer direction is controlled by the host when the peripheral and the host both support bi-directional use of data lines.

EPP mode - provides an asynchronous, byte-wide, bi-directional channel controlled by the host device. This mode also provides separate address and data cycles over the eight data lines of the interface. EPP increases the data transfer performance to 2 MB per second while retaining backward compatibility with existing AT and PS/2 compatible interfaces.

ECP mode - similar to EPP, providing an asynchronous, byte-wide, bi-directional channel controlled by the host device. Additionally, ECP implements a control line to distinguish between command and data transfers. A command may optionally be used to indicate single byte data compression or channel address. Other ECP mode features include:

−

Supports 2 MB per second data transfer rate

−

High performance, half duplex, forward and reverse channel

−

Interlocked handshake for fast, reliable data transfer

−

Channel addressing for low-cost peripherals

−

Link and data layer separation

−

Active output drivers and adaptive signal timing

−

Peer-to-peer capability

The addresses and interrupts used by the external parallel port can be assigned in AMIBIOS Setup. Refer to the System Setup for information to configure the ports. The parallel port addresses and interrupts are shown in the following table.

Port

Address Interrupt

LPT1 378-37A IRQ7 or IRQ5 LPT2 278-27A IRQ7 or IRQ5 LPT3 3BC-3BE IRQ7 or IRQ5

PCI-to-ISA Bridge

The Intel 82379AB System I/O-APIC (Advanced Programmable Interrupt Controller) bridges the ISA bus off the Primary Compatibility PCI bus (PCI bus 0). The 82379AB supports all four ISA expansion slots.

PCI-to-PCI Bridge

The DEC 21050 PCI-to-PCI bridge supports the PCI bus 2 (also known as Secondary Auxiliary),

which is bridged off PCI bus 1. PCI bus 2 includes the expansion slot 8 through 12. Refer to “PCI Bridge” on page 51 for a description of PCI bus 0 and PCI bus 1.

Lithium Battery

The Lithium battery on the I/O expansion board provides power to the CMOS chip (which stores the BIOS and the AMIBIOS Setup program) and Real Time Clock. If the battery fails or if the voltage is low, the message “Battery voltage low” displays during system startup, or the system date and time information will not display. The battery on the MSMT451 board is not replaceable. If the battery fails, the board must be replaced.

Flash EPROM (BIOS Chip)

The flash EPROM chip (MYPG833) contains the system’s Basic/Input Output System (BIOS) and the AMIBIOS Setup program, used to modify BIOS settings. The System Setup contains information about using AMIBIOS Setup and reprogramming the flash EPROM with a new BIOS when necessary.

I/O Connector Board (MSMT328)

The I/O connector board plugs into the interface connector on the I/O expansion board. This board provides all the external connections required by the various components integrated into the I/O expansion board.

LCD Board (MSMT344)

The LCD board consists of a four-line display screen, soft-touch buttons and status LEDs that allow users to monitor system and disk section status (RAID systems only). The display screen reports various system status and events in a software-independent manner. The 550 Watt power supplies feature an always on +5V output. System status information is available if the system is powered off, as long as the system is plugged in and the circuit breaker switch is in the ON position. If the system uses the 539 Watt power supply, status information is only available when the system is powered on.

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 power supply, internal disk section, temperature sensors, safety interlocks, and fans, and generates the appropriate alarms and alerts.

The LCD board is the collection point for system status information reported over the I2C serial bus. This bus initiates at the I

C chip on the I/O expansion board. An 80C51-derivative microcontroller on the LCD monitors the status of various system components and displays the status to the LCD screen. Refer to the System Setup, delivered with the system, for a detailed description of the status items detected by the microcontroller and the menus available on the LCD screen. The microcontroller contains the password code for intruder alert. By default, the password is null, it has not been set. Use the fail-safe password, 44234423, in case the user password is forgotten.

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. Holding the keyswitch in the reset (//) position for at least four seconds will bypass the microcontroller and directly turn on the power supplies. 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 disk section. This module is used in all systems, RAID and non-RAID.

SAF-TE Card

The SAF-TE card (MSMT460) is the primary component that makes the disk section a RAID-capable subsystem. This card is only installed in systems that include the AMI RAID controller (MSMT489). If the UW SCSI controller (CINFD80) is used, then the card is not present. Non-RAID system can be upgraded to RAID by swapping the UW SCSI controller and adding the SAF-TE card. Refer to

Chapter 3, “Upgrading the System” for details.

Jumper Settings

The disk section backplane has two jumper headers, spin-up delay (JP2) and SCSI ID (JP3), that are used with the Ultra Wide SCSI controller in non-RAID systems. Non-RAID systems must have the delay and SCSI ID jumpers installed.

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

delay and SCSI ID setttings are controlled by the RAID controller.

Spin-up Delay

The jumpers on JP2 (4 position, dual-row header) are used to set the delay time between drive power on and spin up. This ensures all the drives power on properly. If all the drives power on simultaneously, failures could occur. The following table shows he jumper settings which define the spin-up delays.

Jumper on Pins 1 and 2

On On Drive motor spins up only on SCSI “start” commands. On Off DEFAULT SETTING: Motor spins up after delay of 12

Off On Drive motor spins up only on SCSI “start” commands. Off Off Motor of all drives spin up at DC power on.

SCSI ID

The jumpers on JP3 (eight-position, dual-row header) are used to set the SCSI IDs for all of the disk drive slots in a non-RAID system. The following table shows the correlation between the JP3 pins and the disk drive slots.

Operating Characteristics

The power supplies operate in the following manner.

Over-Current Protection is provided on +3.3 VDC and +5.1 VDC outputs. The Over-Current Protection disables the DC outputs (except the +5.0 V) and keeps them disabled until AC is cycled.

Over-Voltage Protection is provided on +3.3 VDC and +5.1 VDC. The Over-Voltage Protection disables the DC outputs (except the +5.0 V) when the output reaches 5.5-6.8 VDC for +5.1 V DC or 3.7-4.4 VDC for +3.3 VDC. The DC outputs remain disabled until AC is cycled.

Once the +5.1 V output is turned on by the power supply, it reaches its nominal output (see the table above) within 750 ms at all line and load conditions.

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. +3.3 V, +5.1 V, +12 V, -5 V, and

-12V power outputs have series-connected blocking diodes to prevent an output fault in one power supply from pulling down the outputs of the other power supply.

If one of the power supplies fails, the DC LED on the back of the power supply goes out, and the power supply status LED changes from green to amber. Look at the back of the base unit to see which power supply failed.

If a power supply is not supplying all of its DC voltage output levels correctly, an audible alarm sounds.

Connector Pinout

The power supply has two connectors that attach to J18 and J19 on the power distribution board. Both connectors have the same pinout, as follows.

Name Pin Name Pin Signal

NOTE The AC OK signal is a TTL-compatible signal. It monotonically (without wavering) transitions to a high

level to indicate that the AC input power is within 90-132 VAC or 180-264 VAC. The signal provides the 3 mA sink/source current as well as any current required for the LEDs. Provided that there is an AC input, this signal must be available to report whether or not the outputs are functional. Overshoot should be kept to less than 1 V above a maximum steady-state high-level output of 5 V. Undershoot should be kept to less than -1 V below a minimum steady-state low-level output of 0 V.

NOTE The DC OK signal is a TTL-compatible signal, and its purpose is to initiate an orderly start-up

procedure under normal operating conditions. During power up, this signal should remain low (less than 0.8 V) for at least 100 ms after all of the +5.1 V, +3.3 V, and +12 V outputs have reached their minimum sense levels of 4.75 V, 3.14 V and 11.4 V, respectively. The signal then monotonically (without wavering) transitions to a high level (greater than 2.4 V) to indicate that the power source is stable. The signal provides the 3 mA sink/source current as well as any current required for the LEDs. Overshoot should be kept to less than 1 V above a maximum steady-state high-level output of 5 V. Undershoot should be kept to less than -1 V below a minimum steady-state low-level output of 0 V.

The power connector uses MCBL206A power supply cable from the power distribution board. See the table “J22: MCBL206A, CD-ROM Drive and Floppy Disk Drive” on page 68 the for pinout.

Disk Drives

The disk drives use one connector that carries power, data, and SCSI ID signals. This connector plugs into the connectors in the backplane of the disk section (MESAN52). The following disk drives are available for the server:

Part Number

FDSK461 4.3 GB 1-inch high FDSK470 9.1 GB 1.6-inch high

The same disk drives are used whether the system is RAID capable or non-RAID. The RAID functionality is provided by the AMI RAID controller (MSMT489) and SAF-TE card (MSMT460). Non-RAID systems use the Ultra Wide SCSI adapter (CINFD80), which does not provide RAID functionality.

Floppy Data Connector

The floppy connector uses cable MCBL106A and connects to J30 on the I/O expansion board. Refer to the table “J29: MCBL106A, Floppy” on page 56 for the cable pinout.

Cooling Fans and Temperature Sensors

The server uses three main fans (MCBL207A) to provide air flow through the middle and upper areas of the system. The power supplies (MPWS131 and MPWS139) each contain two fans that provide airflow for the lower area of the system. These fans are RPM-reporting so their status is available on the LCD screen. The fans for the 550 Watt power supply are enclosed in the power supply housing. The fans for the 539 Watt power supply are separate from the power supply; their part number is MCBL243A.

Four temperature sensors are located in strategic locations to report internal temperatures to the system monitor. The following table shows the sensor locations and the temperatures at which the system monitor firmware reports warm and hot. Additional information about the LCD screen is in the System Setup.
