1 Before You Begin

Review this chapter before installing the InterServe 8400 into the Intergraph rack.

u

Set up the Intergraph rack using the Intergraph Rack Installation and Use (DHA0194x0,
supplied with the rack), and become familiar with the rack enclosure before installing the system
hardware.

u

Ensure that all Intergraph equipment has the necessary mounting hardware and other associated
items as described in each section. If any items are missing, contact the local support office
immediately to obtain the missing items.

u

Retain all packaging materials. To return equipment for repair, the customer must return it in
the original packaging to obtain warranty service (if provided by their contract agreement).

WARNING If using non-Intergraph cables with the system, ensure that they are shielded and terminated

on both ends.

Safety Precautions

1

InterServe Base Unit

u

The base unit is subject to high leakage current, and must be properly grounded. To assure
proper grounding, connect the base unit power cord only to the designated outlet on the AC
distribution box or uninterruptible power supply (UPS).

u

The base unit weighs 125 pounds (57 kg) without RAID disk drives. Two people must lift the
base unit when removing it from the pallet and installing it into the rack.

Intergraph 19-inch Rack

WARNING The Intergraph rack is intended for use only with Underwriter’s Laboratories Listed rack-

mountable accessories which meet the criteria below and are suitable for use in a 26 °C
ambient temperature.

u

Fixed devices may not weigh more than 20 pounds (9.0 kg) per vertical U (1.75 inches). The
center of gravity of fixed devices must not be deeper than 15.0 inches (38.1 cm) inside the rack.

u

Slide rail devices (between 5 U and 11 U) may not weigh more than 13.6 pounds (6.2 kg) per U.
These devices may not be extended more than 31.5 inches (78.8 cm) and their center of gravity
must not extend beyond 16.5 inches (49.1 cm).

u

Slide rail devices (less than 5 U) may not weight more than 20 pounds (9.0 kg) per U. These
devices may not be extended more than 24 inches (61 cm) and their center of gravity must not
extend beyond 13 inches (33 cm).

u

If more than one slide rail device is installed, only one device may be extended at a time. Should
you need access to a device while another is extended, push the extended device back into the
rack before extending the next device.

WARNING Extending more than one device at a time could cause the rack to fall forward, causing damage

to the equipment and injuring anyone standing in front of the rack.

2

u

Do not push on or lean against the rack. The front and side stabilizer feet must be extended at all
times.

u

Install bottom components into the rack first.

Power Requirements

This section provides information about the power requirements of the AC distribution box supplied
by Intergraph with some systems. Intergraph provides separate AC distribution boxes for domestic
and non-domestic use. This section describes the specifications and functionality of both types.

NOTE If the cutomer purchased a UPS instead of an AC distribution box, refer to the documentation

delivered with the UPS for power information.

Domestic AC Distribution Box

Specifications for the domestic AC distribution box include:

u

AC input: 110/220 VAC 60 Hz, 16 Amperes

u

Receptacles: eight NEMA 5-15R and one NEMA 6-15R

u

Power cable: 9 feet, 12 AWG, 4 conductor with NEMA L14-20P plug

u

Output rating: 1760 VA/phase @ 110 VAC, 3520 VA total

The domestic AC distribution box is rated for a maximum output rating of 3520 VA (Volt-Amperes)
at 110 VAC. The sum-total VA load that the devices pull must not exceed this maximum, else a
breaker in the AC distribution box trips when power is applied. A second AC distribution box must
be installed to provide the additional power requirement. The following figure shows the domestic
AC distribution box.

Each receptacle on the AC distribution box is rated for a specific VA. The 6-15R receptacle (J9) is
used for the power cord to the server. The remaining eight receptacles (110 V each) are for
additional devices installed in the rack. Notice that the left four (J1-J4) and right four (J5-J8) are on
different phases. Follow these guidelines when connecting equipment power cords:

u

If the NEMA 6-15R receptacle (J9) is not used, then the eight NEMA 5-15R receptacles can
support the full 3520 VA load (1760 VA per phase).

u

If the NEMA 6-15R receptacle (J9) is used, then the eight NEMA 5-15R receptacles can support
1760 VA load (880 VA per phase).

u

The power load should be balanced between the phases of the 110 VAC receptacles. For
example, do not plug four 110 VAC 2 Amp devices into phase I; instead, plug two of the devices
into the phase I and two into phase II.

WARNING The wall outlet to which the AC distribution box is connected must be a NEMA L14-20R type

outlet on a properly grounded branch circuit.

Non-Domestic AC Distribution Box

Specifications for the non-domestic AC distribution box include:

u

AC input: 190/264 VAC 50 Hz, 16 Amperes

u

Receptacles: eight IEC 320 10 Amperes, and one IEC 320 16 Amperes

u

Power cable: 2.5m with IEC 309 16 Amperes plug

u

Output rating: 3520 VA total @ 220 VAC

The non-domestic AC distribution box is rated for a maximum output rating of 3520 VA (Volt­amperes) at 220 VAC. The sum-total VA load that the devices pull must not exceed this maximum,
else a breaker in the AC distribution box trips when power is applied. A second AC distribution box
must be installed to provide the additional power requirement. The following figure shows the non­domestic AC distribution box.

3

IEC 320 IEC 320 Power
10 Amp 16 Amp switch

Each receptacle on the AC distribution box is rated for a specific VA. The IEC 320 16 Ampere
receptacle (J9) is used for the power cord from the base unit. The remaining eight IEC 320 10
Ampere receptacles are for additional devices installed in the rack. Follow these guidelines when
connecting equipment power cords:

u

If the J9 receptacle is not used, then the eight 10 Ampere receptacles (J1-J8) can support the full
3520 VA load.

u

If the J9 receptacle is used, then the eight 10 Ampere receptacles (J1-J8) can support only 1760
VA load.

WARNING The wall outlet to which the AC distribution box is connected must be an IEC 309 type outlet

on a properly grounded branch circuit.

4

Equipment Power Loads

The power load values for the base unit and disk array cabinet are provided below. Load values of
equipment must be taken into account when installing equipment to the rack.

Device

System base unit with eight drives 1200 VA
Disk drive cabinet with eight 4 GB drives 265 VA
Disk drive cabinet with eight 9 GB drives 261 VA
4-port concentrator 8 VA
8-port concentrator 10 VA
PC extender 13 VA

The VA load of Intergraph rack-mount options is printed on the back of the device. Add the VA load
for each device to determine if the AC distribution box can handle the load. If it cannot, add an
additional AC distribution box. The VA load of a device is the product of its operating Voltage (such
as 110 V or 220 V) times its current rating (2 Amperes, 3 Amperes, 6 Amperes, etc.).

Placing the System

Before you unpack the equipment and begin setting up your server, determine where you want to
place the system rack. Keep these guidelines in mind:

u

Place the rack as close as possible to the proper wall outlet. The power cord connecting the AC
distribution box or UPS to the wall outlet serves as the disconnect device.

u

Place the rack in an area where air can circulate freely around it. Ensure that the front and the
back of the rack each have 36 inches of clearance for servicing the installed hardware.

Max Load

u

Do not expose the system to high levels of dust, smoke, or moisture.

u

Place the system in an area where the temperature range stays between 10 °C and 26 °C (50 °F to
80 °F). The optimum operating temperature is 21 °C (70 °F).

u

Place the system in an area where the humidity stays between 20 and 80 % (non-condensing).
The optimum operating humidity is 50 % (non-condensing).

u

The rack is not designed to be moved when equipment is installed (other than equipment that is
pre-installed by Intergraph).

WARNING Once you install the equipment, do not move the rack. If you must move it, then remove all

equipment, move the rack to its new location, and reinstall the equipment.

2 Installing the InterServe 8400

This chapter describes how to install an InterServe 8400 and additional equipment into an Intergraph
rack. The equipment is secured in the rack along the side mounting posts, which have industry
standard 7.1 mm diameter mounting holes along the edge. The mounting posts have small round
markers to designate each vertical unit, or U. There are three mounting holes per U, and at every 4 U
there is a small square marker. The total vertical mounting height within the rack is 40 U.

The system components should be installed in the following order:

u

Uninterruptible power supply (UPS)

u

InterRAID-8e disk array cabinet

u

InterServe base unit

u

Rack-mount interface peripherals (keyboard, mouse, monitor)

u

Disk drives

u

System power and data cables

u

Rack cable handlers

5

u

Accessory components

WARNING Follow the installation instructions explicitly to avoid personal injury and damage to the server

hardware.

CAUTION To keep the rack from moving, ensure the front and side stabilizers are fully engaged and the leveling

feet are lowered firmly to the floor before installing equipment into the rack.

Note the following points before installing equipment into the rack:

u

The rack must be properly set up before placing any equipment into the rack. If installing the
equipment into an Intergraph rack, follow the instructions in Intergraph Rack Installation and Use
(DHA0194x0) supplied with the rack.

u

Do not start the system until it has been completely set up. After setup is complete, refer to the
System Setup document delivered with the system for startup and configuration instructions.

u

As equipment is installed into the rack, some components may not align properly with the holes in
the mounting posts. This occurs because some components have different tolerances in regards to
their height. If components do not align properly, loosen their screws and adjust support rails and
shelves where necessary so the components can be supported by the proper shelves or rails, rather
than by the component underneath.

u

The hole numbers stated in the instructions assume the following:

− a UPS is installed first, in the lowest 4 U space;

− an InterRAID-8e is installed next, just above the UPS; and

− the InterServe 8400 is installed next, just above the InterRAID-8e.

Installing Disk Drives

The disk section in the front of the system contains eight disk drive slots. The slots are numbered
from 1 to 8, starting with the right slot. If you are installing less than eight drives into the system,
install the disk drives starting in slot 1 and fill each slot in sequence. Use the key provided in the
parts box to unlock and open the disk section door.

The disk drive boxes can hold up to six disk drives. Depending on the configuration, the system is
RAID or non-RAID system. The RAID system uses a 2-channel AMI RAID controller to provide
RAID capabilities such as disk striping, mirroring, and redundancy. The non-RAID system use a 2­channel Ultra Wide SCSI controller that does not feature any RAID capabilities.

Each disk drive has a label affixed to the front. The left side of the disk drive label identifies the disk
drive size (in GB). The label has blank spaces for the numbers to indicate the adapter (ADP),
channel (CH), and SCSI ID (ID). Standard disk drives include values for the adapter, channel, and
SCSI ID filled in. Additional disk drives have a blank label which you must complete after
installation.

NOTE A labeling sheet is included in the system parts box.

cables through these ties and clamps if necessary.

NOTE Cables that are attached to the base unit and connect to devices in another rack must also be inserted

into the cable handler.

4. After routing the cables into the cable handlers, fully extend the base unit to ensure there is

enough service loop in the cables.

30

Additional Rack-mount Equipment

Network hubs, routers, serial devices and other types of equipment may be installed into the rack,
provided the power requirements are within the available limits of the installed AC distribution box
or UPS.

CAUTION Refer to “Safety Precautions” and “Power Requirements” in Chapter 1, before attempting to install

additional equipment.

WARNING If using non-Intergraph cables with the system, ensure that they are shielded and terminated

on both ends.

To install additional equipment into the rack:

1. Ensure that the installed AC distribution box or UPS can support the additional equipment.

2. Install the necessary mounting shelves or rails to support the equipment into available space. Use

tinnerman nuts for the shelves or rails.

3. Install the equipment, and place tinnerman nuts where the equipment will bolt into the rack.

Secure the equipment to the rack.

4. Connect the cables to the equipment and to the appropriate ports on the back of the base unit.

All cable ports on the base unit and other Intergraph equipment are keyed or molded to ensure proper
cable attachment. If a cable is not attaching easily, ensure that you are aligning the cable connector
correctly with the port.

Memory Subsystem Description

The processor board uses industry-standard 60 ns, fast page mode, 72 pin (parity pinout) SIMMs.
The board has 32 SIMM sockets.

u

There are four banks in the memory subsystem system, each bank containing eight sockets. Bank
0 is half-populated (four SIMMs) for base memory configurations (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.

u

InterServe 8400 supports three SIMM sizes: 8Mx36 (32 MB), 16Mx36 (64 MB), and 32Mx36
(128 MB). Base systems with 128 MB (four 8Mx36 SIMMs) can be expanded with 8Mx36
SIMMs, for a maximum memory support of 1 GB. Base systems with 256 MB (four 16Mx36
SIMMs) can only be expanded with 16Mx36 SIMMs, for a maximum memory support of 2 GB.
Base systems with 512 MB (four 32Mx36 SIMMs) can only be expanded with 32Mx36 SIMMs,
for a maximum memory support of 4 GB. Only four SIMMs in Bank 0 are installed for base
memory.

Memory is organized into words, rows, and interleaves.

u

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.

u

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).

u

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 0 Rows 0/1 (i0, i1, i2, i3)
Bank 1 Rows 2/3 (i0, i1, i2, i3)
Bank 2 Rows 4/5 (i0, i1, i2, i3)
Bank 3 Rows 6/7 (i0, i1, i2, i3)

The following table shows the correlation between interleaves, words, rows and the socket J numbers. The ECC
Memory 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 Memory Monitoring Utility
Help for more information.

NOTE Since the 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.

Memory Sockets

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, high-bandwidth devices that efficiently use PCI burst protocols to transfer data as bus
masters should reside on PCI bus 1 or 2 (slots 1 though 7).

Lithium Battery

The Lithium battery on the processor board provides power to the real time clock, which the power
distribution 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. You can replace the failed battery following these instructions:

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

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

44

To replace the Lithium battery:

1. Remove the peripheral drives. It is not necessary to disconnect their attached cables.

2. Carefully remove the discharged battery by grasping it firmly and lifting upward.

3. Install the new battery in the same orientation as the discharged battery.

4. Replace the peripherals.

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

DMA Channels

The system board uses Direct Memory Address (DMA) channels to exchange data without accessing
the CPU. Some channels are assigned for specific use by the system, as defined below. Each DMA
channel appropriates full 32-bit processing. For an ISA bus, channels 0 through 3 are 8-bit and
channels 4 through 7 are 16-bit channels.

Component Descriptions

The IO Expansion Board provides PCI and ISA expansion slots. It also has the graphics, non-RAID
SCSI, mouse, keyboard, serial port, parallel port, and floppy controllers, as well as the PC
compatibility hardware (BIOS PROM, NVRAM, RTC) and interrupt logic.

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.

51

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
Real-Time 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 document delivered with the system. 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:

u

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.

52

u

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.

u

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.

u

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:

−

Support for 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 document delivered with the system 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

Expansion Connector

The expansion connector carries signals from SCSI, Super I/O, and graphics controllers to the I/O
connector board (MSMT328) for external devices.

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 (Secondary Auxiliary bus), which is

bridged off PCI bus 1. PCI bus 2 includes the expansion slots 8 through 12. Refer to “PCI Bridge”
on page 43 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.

I/O Connector Board (MSMT328)

The I/O Connector Board plugs into the I/O Connector provided by the I/O Expansion Board. This
panel provides all the external connections required by the various components integrated into the I/O
Expansion board.

LCD Board (MPCBD20)

The LCD board consists of a four-line display screen, soft-touch buttons and status LEDs that allow
users to monitor system and internal RAID status. The display screen reports various system status
and events in a software-independent manner. A +5V (always on) output powers the textual display
of the panel. System and RAID status information is available even if the system is powered off, as
long as the system is plugged in and the circuit breaker switch is in the On position.

The following figure shows the board layout.

Power Distribution Board (MSMT385)

The power distribution board is used as an interconnect between the processor board, the I/O
expansion board, the power supplies, the internal RAID section, and the LCD display subsystem. It
functions as a central resource through which system power and status signals are routed. The system
monitor PAL (programmable array logic) accepts status inputs from the power supply and generates
the appropriate alarms and alerts.

The board contains firmware on a PROM for the LCD menus. The firmware contains password code
for intruder alert. There is a fail-safe password 44234423 that can be used in case the user-password
is forgotten. The PROM can be replaced in the field without removing the board. By default, the
password is null, that is, it has not been set.

The LCD menus and intruder alert password information is provided in the System Setup document
delivered with the system.

NOTE The power distribution board has two attached stiffeners: CFAB584F on the I/O expansion board side,

and CFAB351F on the processor board side. This assembly is MESAN180.

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 Ca rd

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.

63

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 (CINFD80) 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 (MSMT489), 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.

Power Supplies (MPWS139)

The InterServe 8400 uses three redundant 550 watt current-sharing power supplies. Each power
supply has six outputs, is hot swappable, and is auto-ranging between 90 - 132 VAC and 180 - 264
VAC. The input frequency range for each power supply is 47 - 63 Hz, single phase. The power
supply has the following DC output specifications:

Nominal Output Voltages

1, 3

Continuous Load (Maximum)
Continuous Load (Minimum)
Noise and Ripple (PARD)

(DC to 30 MHz)
Initial Setting Tolerance
Regulation Line/Load

DC Output Specification Notes:

1. The power supply meets or exceeds these specifications.

2. These outputs are measured differentially at the Elcon connector terminated with 0.1 µf ceramic

capacitor.

3. The sum of the Initial Setting Tolerance and Line/Load Regulation does not exceed 3% for the
+3.3 V, +5.1 V, and +5.0 V (always on) outputs, 5% for the +12.0 V output, and 10% for the
negative output voltages.

4. Any combination of +3.3 V or +5.1 V do not exceed their maximum power or 450 watts of total
power.

5. Any combination of +3.3 V, +5.1 V, or +12 V do not exceed their maximum power or 550 watts
of total power.

6. This output is always on.

Operating characteristics of the power supplies include the following:

u

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.

u

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.

u

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.

u

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.

u

If one of the power supplies fails, an LED in that power supply either goes out or changes from
green to amber, and the power on LED on the front of the base unit changes from green to
amber. Look at the back of the base unit to see which power supply failed.

u

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

The pinout for the power supply connectors (which plug into J4, J5, J6 on the power distribution
board) is as follows.

Pinout Notes:

1. 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 steady­state low-level output of 0 V.

2. 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.

5 Accessing the System

This chapter describes servicing restrictions, opening the base unit, avoiding electrostatic discharge,
and closing the base unit.

Servicing Restrictions

Upgrading and servicing the system is restricted to qualified personnel. Heed all warnings and
cautions in servicing instructions. Personal injury and damage to equipment can occur if documented
procedures are not followed.

WARNING The system produces high-leakage current. When servicing or upgrading the base unit, flip

the circuit breaker to the Off position.

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

discharge.

73

Opening the Base Unit

CAUTION Shut down the system and turn off system power. Use caution to avoid injury when removing covers

and other hardware. Ensure the front and side stabilizer feet are extended at all times.

CAUTION Ensure the board ejectors on both sides of the base unit are closed before extending the system out of

the rack.

To open the base unit:

1. Remove the screws from each corner of the front of the base unit.

2. If removing the back cover, remove the screws located on the top corners at the back of the base
unit. Refer to the following figure.

3. Pull out the base unit from the rack until it locks in the extended position.

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.

u

Touch the bare metal of the base unit to ensure the base unit and your body are at the same
electric potential.

u

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.

u

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.

u

A reusable antistatic wrist strap can be attached to any bare metal part of the base unit. The
metal conductor bead 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 covers that were removed. The covers

ensure the system maintains proper air flow, so internal components do not overheat and fail. The
covers also ensure that electromagnetic interference (EMI) emissions remain below the standard
requirements.

CAUTION Ensure the board ejectors are closed before retracting the base unit into the rack.

To close the base unit:

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

2. Replace the top covers. Secure the front top cover with the flat-head screws.

3. Press the buttons on the rails, and then push the base unit into the rack.

4. Examine the sockets and become familiar with the memory module layout as shown on page 78.

5. Remove all installed SIMMs.

6. 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 them 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, 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.

7. Rotate the air baffle into its proper position and replace the thumb screw.

8. Replace the peripherals.

80

9. Close the system.

10. Restart the system. The total installed memory displays at the blue Windows NT boot screen.

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 Option Boards

This section describes how to install option boards. The following paragraphs provide some
information about the design of Peripheral Component Interconnect (PCI), non-compliant PCI,
Industry Standard Architecture (ISA), and Plug-n-Play (PnP) option boards, and how it relates to
installing and configuring them.

u

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.

u

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 the SCU) before installing the board. In this regard, they are like ISA boards, as
described below.

u

ISA boards do not contain registers that define the resource information to the system during
startup. Therefore, you must run the SCU 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 Resources for Option Boards” on page 81.

u

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.

NOTE All PCI option boards sold by Intergraph fully comply with the

Specification, 2.1.

Peripheral Component Interconnect

To install option boards:

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

section, “Assigning System Resources for Option Boards”.

1. Remove the back top cover as described in Chapter 5.

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

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

4. Secure the board to the chassis using the screw removed previously.

5. Close the base unit.

6. Restart the system, and note the special information about PnP boards and the InterSite Server
Monitor card.

−

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 PnP setup menu. Exit AMIBIOS Setup and restart the system.

−

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 so they do not conflict with other boards. Refer to the
System Setup document delivered with the system for instructions to use AMIBIOS Setup.

Assigning Resources for Option Boards

Some option boards include a configuration diskette that you can use to reserve the system resources
required for the board. Other option boards do not include a diskette, but require that you manually
enter the configuration information. The next two sections describe how to reserve the resources for
both types.

NOTE The SCU is an MS-DOS utility that will not run in the Windows NT environment. Use the System

Utilities (SYSUTIL) diskette delivered with your system to boot the system into MS-DOS. The system
must be set to boot from the floppy disk drive (normally drive A) to use the SCU. If necessary, refer to

“Changing the System Boot Sequence” in the

NOTE For a list of available system address resources (DMA, I/O, memory) refer to “Processor Board

(MSMT329)” in Chapter 4.

NOTE Treat non-compliant PCI boards and PC Cards as ISA boards for assigning system resources.

Option Boards with a Configuration File

Some ISA boards are shipped with a diskette containing a configuration file. The configuration file
can be loaded to the system so that the BIOS reads this file to assign resources during startup. If you
install ISA boards that are shipped with a configuration diskette, follow this procedure.

NOTE If a configuration diskette is not delivered with the option board, refer to “Option Boards without a

Configuration File.”

6. Slide the device into the slot and secure it to the chassis.

7. Connect the power cable and SCSI cable to the device.

86

8. Close the base unit and restart the system.

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

instructions.

Adding External SCSI Devices

You can add single-ended 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 to install new boards.

Understanding Cable Lengths

The InterServe 8400 is 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 Sync Negotiation” on
page 87 to configure the controller.

The total length of the SCSI cabling is the sum of the following:

u

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

u

SCSI cable inside the base unit - 3.8 feet (1 m)

u

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

u

SCSI cable between the base unit and the first device

u

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 (0, 1, 2, 3, 5, or 6). By default, the following

devices use certain SCSI IDs:

−

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 Sync Negotiation

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

87

To disable sync negotiation:

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

2. From the SYSUTIL main menu, select SCSISelect 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 if available).

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.
