Protecting Against 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 internal components of the system.
u
Do not service the system on surfaces known to have high electrostatic buildup, such as rugs and
carpets. Work on a static-safe surface instead.
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 re-usable antistatic wrist strap when servicing or upgrading the system. A
disposable wrist strap can only be used once.
Page 18
8
u
A re-usable antistatic wrist strap can be attached to the ground loop above the ISA slots, as shown
in the following figure, or to any other bare metal part of the base unit. The metal conductor bead
in the elastic sleeve of re-usable antistatic straps must contact bare skin.
Ground Loop
Closing the System
CAUTION After servicing or upgrading the system, always replace the panels and covers that were removed. The
panels and covers ensure the system maintains proper air flow, so internal components do not
overheat, causing failure. The panels and covers also ensure that electromagnetic interference (EMI)
emissions remain below the standard requirements.
NOTE When securing panels with screws, ensure the screws are tight, but do not strip the screw heads.
To close the system:
1. Remove the antistatic wrist strap from the base unit.
2. Replace the PCI access panel if removed.
3. Set the base unit in the upright position.
4. Replace the left and right side panels if removed.
5. Replace the top cover if removed. Ensure the top cover is completely installed so the safety
interlock switch engages. If the cover is not properly installed, the system will not start.
6. Replace the stabilizer feet.
7. Restart the system.
Page 19
2 Servicing System Parts

System.” After servicing, close the base unit as also described in Chapter 1.
WARNING Leave the AC power cord from the InterServe 615, 615UW, 625, and 625UW base unit connected
to the AC wall outlet to maintain safety ground. If the AC power cord is disconnected, you could
be injured or cause damage to the system.
WARNING Hazardous voltages exist inside the InterServe 635 and 645 base unit. Disconnect the AC power
cord from the base unit before servicing the system. If the AC power cord remains connected,
you could be injured or cause damage to the system.

3 Upgrading the System
You can upgrade your server by adding processors, memory, internal or external SCSI devices (such as
disk drives and tape drives), and option boards. This chapter also describes how to use the System
Configuration Utility (SCU) when adding ISA option boards, non-compliant PCI option boards, and
PC Card devices.
WARNING Leave the AC power cord from the InterServe 615, 615UW, 625 and 625UW base unit connected
to the AC wall outlet to maintain safety ground. If the AC power cord is disconnected, you could
be injured or cause damage to the system.
WARNING Hazardous voltages exist inside the InterServe 635 and 645 base unit. Disconnect the AC power
cord from the base unit before upgrading the system. If the AC power cord remains connected,
you could be injured or cause damage to the system.
CAUTION The parts inside the base unit are designed to fit within very tight tolerances; some force is required to
remove or insert parts. However, if you cannot remove or install a part properly, ensure that there are
no obstructions hindering the part.
Adding Processors
Single to dual processor upgrade kits include a CPU with attached heat sink, Voltage Regulator
Module (VRM), and a metal clip. Dual to quad upgrade kits contain two processors, two VRMS, two
metal clips, a processor module (MSMT310), and screws.
Single to Dual Upgrade
To upgrade a single processor system:
1. Open the base unit and remove the necessary parts as described in Chapter 1.
NOTE If full-length ISA option boards are installed, they must be removed to access the CPU sockets.

Adding Internal SCSI Devices
You can install internal SCSI devices such as hard disk drives, tape drives, and CD-ROM drives in the
auxiliary drive bays of the server. However, a bracket must be removed from the destination bay prior
to installation. The bays are designed to accommodate one-inch high devices. If the device is more
than one inch high, then the bay underneath must be empty.
NOTE When installing a SCSI device, carefully follow the vendor’s instructions for setting the SCSI ID and
disabling the SCSI termination before installing the devices.
NOTE Systems with the internal RAID subsystem have one bay available for an optional SCSI device.
Systems without internal RAID have five bays available.
To install an internal SCSI device in the auxiliary drive bay:
1. Open the base unit and remove the necessary parts as described in Chapter 1.
2. Select a bay to install the device and remove the blanking plate or other device from the
destination bay.

Slide
Bracket
Adding External SCSI Drives
You can add single-ended external SCSI drives 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 drives as well. The section “Adding Option Boards” earlier in this chapter describes installing
new boards.
The Adaptec AIC 7860 SCSI controller on the system board provides the Ultra SCSI bus for external
devices.
SCSI Cable Guidelines
If you are using a SCSI adapter card, this information also applies.
The number of drives and length of the cables used to connect the drives becomes a factor when using
SCSI-1, Fast (SCSI-2), Ultra SCSI, and Ultra Wide SCSI drives. Fast SCSI, and Ultra SCSI impose
shorter cable restrictions than SCSI-1. The total length of the SCSI cabling must not exceed the
following:
Drives
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) 4.5 feet (1.5 meters)
NOTE The SCSI controller (on the system board or an adapter card) counts as one device.
SCSI-1 Fast SCSI-2 Ultra SCSI
Page 45
The total length of the SCSI cabling is the sum of the following:
u
SCSI cable inside the base unit - 6.0 inches (15 cm)
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
To install an external SCSI device:
1. Set the device’s SCSI ID to an unused number and enable or disable the device’s SCSI termination
according to the note above and the vendor’s instructions.
2. Connect one end of the SCSI cable to the Fast SCSI-2 port on the back of the base unit. If external
devices are already installed, connect the SCSI cable to the available SCSI port on the last device
on the SCSI cable chain.
3. Connect the device to the other end of the SCSI cable.
4. If necessary, install the device drivers and configure the device according to the vendor’s
instructions.
Adding Option Boards
35
This section briefly describes the differences between Peripheral Component Interconnect (PCI), ISA,
and Plug-n-Play (PnP) option boards. Instructions are also provided for installing option boards into
the system.
Option boards are installed on the riser card. PCI boards connect to side one of the riser card, while
ISA and PnP boards can be installed on side two. The following figure shows the slots on the riser
card.
NOTE PCI slots 1 through 4 are on the secondary PCI bus. PCI slots 5 and 6 are on the primary PCI bus.

PCI Boards
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. Some PCI boards do not comply with the PCI
specification, and must be configured as if they were ISA boards using the System Configuration
Utility (SCU). Intergraph only provides PCI boards that comply with the specification.
NOTE PCI Slot 6 is not available in quad processor systems. If you plan to upgrade a dual-processor system
to four processors, the PCI card installed in PCI slot 6 will have to be moved.
CAUTION The system’s PCI slots are limited to 25 W power dissipation per the
Interconnect Specification
. Therefore, PCI boards must draw less than 25 watts of power.
To install PCI option boards:
1. Open the base unit and remove the necessary parts as described in Chapter 1.
2. Using a quarter-inch nutdriver, remove the blanking plate from an available PCI slot. Refer to the
following figure.
Blanking
Screw
Plate
Peripheral Component
3. Install the PCI board. Press firmly to ensure the board seats completely into the riser card slot.
4. Mount the board to the chassis using the screw removed previously.
5. Close the base unit.
6. Restart the system. The new PCI board is recognized and configured automatically during boot
up. If the PCI board does not comply with the PCI specification it must be configured as if it were
a ISA board using System Configuration Utility (SCU).
Page 47
ISA and PnP Option Boards
ISA boards are not designed with internal registers that define the board configuration to the system
during startup. Therefore, you must run the SCU to define the board to the system. Run the SCU
before installing an ISA board to reserve system resources for the board and to prevent conflicts with
option boards already installed. Refer to “Using the System Configuration Utility” later in this chapter.
PnP boards are ISA boards that contain configuration registers like PCI boards. You do not have to
run the SCU to define a PnP board. During startup, the system BIOS automatically detects the installed
board and assigns the necessary system resources. Since PnP boards are ISA-based boards, they can be
installed in the same slots as ISA boards.
To install ISA and PnP boards:
1. Open the base unit and remove the necessary parts as described in Chapter 1.
2. Disconnect the power cable and SCSI cable from the riser card. Refer to the following figure.

Using the System Configuration Utility
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” later in this chapter.
NOTE If installing a PC Card device or a non-compliant PCI card, which require specific system resources,
treat the device as if it were an ISA option board.
ISA 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 “ISA Boards without a
Configuration File” later in this chapter.
To define ISA boards with a configuration file:
1. Shut down and power off the system.
2. Insert the SYSUTIL diskette into the floppy diskette slot of the combo drive; then restart the
system.

Lithium Battery (CMOS/Clock Battery)
When the system is off, the Lithium battery on the system board provides power to the real time clock
and BIOS flash EPROM, which stores the BIOS information. As long as the system is running, the
batteries are not used to sustain the information. If the battery fails, the system date and time will be
lost and the BIOS will not be installed when the system is rebooted. To replace a failed battery, refer
to Chapter 2, “Servicing the System.”
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.
57
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.
I/O Controller
The Standard Microsystems Corporation (SMC) Super I/O Controller (FDC37C932) integrates mouse,
keyboard, serial, parallel (multi-mode), floppy (2.88 MB), and Real-Time Clock (RTC) functions into
one chip.
Page 68
58
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 includes 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.
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:
−
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
Page 69
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.
59
Port
LPT1 378-37A IRQ7 or IRQ5
LPT2 278-27A IRQ7 or IRQ5
LPT3 3BC-3BE IRQ7 or IRQ5
PCI Bridge
The PCI bridge chip (Intel 82454) provides high-bandwidth PCI compatibility for the system. The
bridge chip supports the primary PCI 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 slots 5 and 6 are
on the primary PCI bus. PCI slots 1 through 4 (secondary) are supported by an Intergraph
programmable part on the riser card.
PCI to ISA Bridge
The Intel 82379AB System I/O-APIC (Advanced Programmable Interrupt Controller) bridges the ISA
bus off the Primary PCI bus (PCI bus 0). The 82379AB supports all four ISA expansion slots.
Flash EPROM
The MSMT329 uses a flash EPROM chip (MYPG782) for the system’s Basic/Input Output System
(BIOS). The System Setup Guide contains information about reprogramming the flash EPROM with a
new BIOS when necessary. It also defines the features of the AMIBIOS Setup program, used to
modify the BIOS parameters.
Address Interrupt
Memory Sockets and Components
The system board contains eight memory sockets which accept 72 pin SIMMs from Intergraph. The
sockets are divided into four banks. When all sockets are populated, the memory is four-way
interleaved which results in maximum memory performance. Refer to Chapter 3 for instructions to
upgrade memory. The following figure shows the socket numbers and bank organization.

CPU 1
The Orion memory components (OMC) include the OMC-DP (data path) and the OMC-DC (data
control). 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 1/4 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.
Sound Processor
The sound controller is the Vibra 16C chip from Creative Labs. Integrated onto the system board, the
Vibra 16C is a complete, full-feature MPC 2.0 compliant sound implementation, providing full Sound
Blaster Pro functionality and compatibility. The Vibra 16C has the following features and
specifications:

The Vibra 16C is configured through I/O port accesses. When the system is powered up, the hardware
forces the Vibra 16C to respond to default I/O port addresses, interrupt request (IRQ) level, and direct
memory access (DMA) request and acknowledge. The following table shows the default Vibra 16C
configurations and available programmable settings.

8-bit DMA Req / Ack Level 1 3
16-bit DMA Req / Ack Level 5 7
Interrupt Request Level 10 5, 7
The settings above may be changed in AMIBIOS Setup (see “Chipset Setup” in the Setup and
Maintenance Guide, delivered with the system) so the Vibra 16C internal registers respond to custom
settings. Additionally, the integrated sound subsystem can be disabled by jumper connectors.

NOTE The DC Power Good signal is a TTL-compatible signal that initiates an orderly start-up procedure under
normal input operating conditions. During power up, this signal should remain low (< 0.8 VDC) for at
least 100 ms after the +5.1 VDC output has reached its minimum sense level of 4.75 VDC. The signal
should then transition to high (> 2.4 VDC) to indicate a stable power source. The signal drives an LED
on the back of the power supply to indicate the status (green is good, off is no signal).
NOTE The AC Power Good signal is a TTL-compatible signal that transitions to high to indicate that the AC
input voltage is within the 90 - 132 VAC or 180 - 264 VAC range. The signal drives an LED on the back
of the power supply to indicate the status (green is good, off is no signal). Provided there is an AC
input, this signal must be available to report whether the outputs are non-functional or functional.

Keylock Switch
The keylock switch performs two functions: it physically locks the power supply in the base unit (by
rotating a blade into a slot on the power supply), and engages an AC switch that provides power input
to each supply. The power supply will not come out of the base unit until the keylock switch is turned
to the OFF position.

Circuit Breaker Reset Switch
The circuit breaker contains an external button to indicate power fault status. When the button is
extended (white area showing), a fault has occurred. Do not reset the circuit breaker until after the fault
has been removed. Reset the circuit breaker by pressing the button.
Safety Interlock Switch
The safety interlock switch, located in the top of the base unit, prevents the system from powering on if
the top cover is not properly installed.
Power Cables
These two-wire cables provide the AC line and neutral signals to the power distribution board, which in
turn drives the power supplies.
Power Supply Cable Opening
The main power cable from the power distribution board to the riser card passes through this opening.
If servicing the AC section, be sure the plastic edging remains in the opening to protect the wires from
damage.
Fixed Power Supply (MPWS131)
MPWS131 is a 539 watt autoranging supply, that switches between 90-132 VAC or 180-264 VAC,
depending on the location. The input frequency is 47-63 Hz, single phase. At full load, the power
supply has a minimum efficiency of 65 percent.

Operating Characteristics
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 and keeps them disabled until AC is cycled.

< 5% < 5% < 10% < 10% < 10% Max
u
Over-Voltage Protection is provided on +3.3 VDC and +5.1 VDC. The Over-Voltage Protection
disables the DC outputs when the output reaches 5.5 - 6.8 VDC for +5.1V DC or 3.7 - 4.4 VDC
for +3.3 VDC. The DC outputs remain disabled until AC is cycled.
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.

System Fans
Option Board Fans (MCBLZ520 and MCBLY690)
The option board fans are one 119 mm (MCBLZ520) and two 80 mm (MCBLY690), attached to the
fan housing. The fan power cable MCBLZ530 connects the fans to J68 on MSMT359. All InterServe
systems use these fans.
Auxiliary Fan (CFAN111)
Only InterServe 615 and 625 systems with RAID use CFAN111 (92 mm), located under the power
supply. The fan power cable connects to J12 on MSMT359. CFAN110 (fan guard) is installed over
the opening in the power supply access panel. InterServe 615 systems without internal RAID do not
use CFAN111.
System Disk Fan (MCBL172A)
Only non-RAID InterServe systems use MCBL172A, an 80 mm fan mounted to the power supply
access panel. MCBLZ660 is used to connect MCBL172A to the system board.
