Before You Begin
WARNING Disconnect the system and peripheral devices from AC power before servicing
internal components! Failure to remove AC power may result in equipment
damage or personal injury. The GT RAX system is always on when connected
to AC power.
WARNING Follow all warnings and cautions in the servicing instructions. If you fail to
follow documented procedures, personal injury and damage to equipment can
result.
CAUTION Use an antistatic wrist strap for all servicing procedures to avoid the possibility of
electrostatic discharge.
“Right side” and “left side” are as seen fr om the front of the unit.
Tools
You will need the following tools to service the system:
♦ Antistatic wrist strap
♦ Quarter-inch nutdriver
♦ No. 1 and No. 2 Phillips screwdrivers
♦ Three-sixteenth-inch or 5 mm nutdriver
♦ Five-sixteenth-inch or 8 mm nutdriver
♦ Small single-slot screwdriver
Avoiding Electrostatic Discharge
Sensitive components inside the base unit can be damaged by static electricity. To protect against
this possibility, take the following precautions when working with internal components.
♦ Unplug the unit from AC power before servicing any electronic component inside the chassis.
♦ 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.
♦ Attach an antistatic wrist strap to any bare metal part of the base unit. The metal conductor in
the elastic sleeve of reusable antistatic straps must contact bare skin.
Opening the Base Unit
WARNING Before you open the base unit, shut down the system, disconnect the system
from AC power, and turn off power to external devices (including peripheral
devices and the monitor). Use caution to avoid injury when removing covers
and other hardware.
CAUTION Ensure the stabilizers of the rack in which the system is mounted are fully extended.
To open the base unit:
1. Remove the screws that secure the handles to the rack.
2. Disconnect all cables including the power cable, monitor, and all peripheral cables from the
back of the unit.
3. Slide the base unit out of the rack until it locks in the extended position.

Before You Begin
WARNING Disconnect the system and peripheral devices from AC power before servicing
internal components! Failure to remove AC power may result in equipment
damage or personal injury. The GT RAX system is always on when connected
to AC power.
WARNING Follow all warnings and cautions in the servicing instructions. If you fail to
follow documented procedures, personal injury and damage to equipment can
result.
CAUTION Use an antistatic wrist strap for all upgrading procedures to avoid the possibility of
electrostatic discharge.
CAUTION Do not overtighten screws and other fasteners to avoid damaging threads.
CAUTION Follow all warnings and cautions in these upgrade instructions. If you fail to follow
documented, approved procedures, personal injury or damage to equipment can
result.
See Chapter 1, “Accessing the Components,” for details on opening the system and protecting
against electrostatic discharge. These procedures assume you have removed the cover from the
system. “Right side” and “left side” are as seen from the front of the unit. After upgrading the
system, replace panels as described in Chapter 1, “Accessing the Components.”
Adding Memory
You can add system memory to the computer by adding or replacing dual inline memory modules
(DIMMs). The system board has six DIMM sockets, which combined can hold up to 3 GB of
Synchronous Dynamic Random-Acc ess Memory (SDRAM).
CAUTION System memory modules from Intergraph Computer Systems are certified for use
with Intergraph computers at extremes of temperatures and system load to ensure
reliable performance. System memory modules available from other vendors may
not function properly or reliably in your Intergraph computer.
Follow these population rules to correctly install the DIMMs:
♦ Install DIMMs one bank at a time.
♦ The system board has two memory controllers. The primary controller maintains DIMM
banks 0, 2, and 4. The secondary controller maintains DIMM banks 1, 3, and 5.
♦ If you are installing both unbuffered and registered DIMMs, you must install all of the
unbuffered DIMMs in the banks controlled by one memory controller, and all of the registered
DIMMs in the banks controlled by the other memory controller.
♦ For best performance, populate both memory controllers equally when using an even number
of DIMMs. For example, if using two DIMMs, install them into Bank 0 and Bank 1.
See Chapter 2, “Servicing the System,” for instructions to install a DIMM. See Chapter 4,
“System Board,” for DIMM socket locations.
The following table shows possible memory configurations. Each bank contains one socket.

Upgrading Processors
When higher-speed processors become available, you can upgrade the existing processors to faster
processors.
Processors are mounted in a processor retention module that surrounds the processor slots. See
Chapter 2, “Servicing the System,” for information on replacing the processors. See Chapter 4,
“System Board,” for the location of processor slots and related connectors.
You can upgrade processors by purchasing a processor upgrade kit from Intergraph Computer
Systems. The kit contains the hardware, software, and documentation required for the upgrade.
After installing faster processors, you must reinstall Windows NT on the system to ensure proper
operation with the new processors.
Adding Expansion Cards
You can install Accelerated Graphics Port (AGP), Peripheral Component Interconnect (PCI), noncompliant PCI, Industry Standard Architecture (ISA), and Plug-n-Play (PnP) expansion cards in
the system. See below for a general description of the types of cards.
♦ PCI cards contain configuration registers that define reso urce information to the system during
startup. PCI cards do not require manual system configuration when installing the card. The
system BIOS detects the board’s presence during startup and reads information from the
board’s configuration registers to assign the necessary system resources.
NOTE All PCI expansion cards sold by Intergraph fully comply with the
Component Interconnect Specification, 2.1.
♦ Non-compliant PCI cards mechanically comply with the Peripheral Component Interconnect
Specification 2.1, but do no t contain configuration registers that allow the system to
automatically assign the necessary resources. These cards install in PCI slots, but you must
configure the BIOS to assign system resources before installing the card. In this regard, they
are like ISA cards, as described below.
♦ Non-PnP ISA cards do not contain registers that define the resource information to the system
during startup. Therefore, you must configure the BIOS to define the card to the system
before installing the ISA card. This reserves system resources for the card.
♦ PnP cards are ISA cards that contain configuration registers like PCI cards. During startup,
the system BIOS automatically detects the installed card and assigns the necessary system
resources. Since a PnP card is ISA-based, you install it in any available ISA slot.
NOTE Assign system resources for any non-PnP ISA card and any non-compliant PCI
cards before installation. See the “Assigning System Resources” section below.
Peripheral
Each installed PCI card must draw less than 25 watts of power. The total allowable maximum
wattage fo r PCI cards is 175 watts. The PCI slots are limited to 25 watts power dissipation per the
Peripheral Component Interconnect Specification 2.1.
Slot Locations
See Chapter 4, “System B oard,” for the location of the expansion slots on the system board.
PCI slots 1 through 3 a re on a primary PCI bus connected to the primary LE chipset. PCI slots 4
through 7 are on a primary PCI bus connected to the secondary LE chip set. Slot 7 is a shared
PCI/ISA slot; you can install a PCI card or an ISA card in this slot, but not both.
35
Slot 0 - AGP
Slot 1 - PCI
Slot 2 - PCI
Slot 3 - PCI
Slot 4 - PCI
Slot 5 - PCI
Slot 6 - PCI
Slot 7 - PCI (shared)
Slot 7 - ISA (shared)
Installing Expansion Cards
If you are installing a double card set, such as a dual-card graphics controller, repeat the following
procedure for the second card. See the documentation that came with the card for details on
connecting the two cards.
For other cards, such as internal modems or SCSI controllers, see the documentation that came
with the card for details on installation, configuration, cable connections, and operation.
To install an expansion card:
1. Locate an open slot and remove the blanking plate for the slot. Keep the retaining screw.
NOTE If you have no open slots and/or want to replace an existing expansion card, see the
instructions in Chapter 2, “Servicing the System.”
36
2. Remove the expansion card from its antistatic packaging.
3. Slide the expansion card carefully into the card guides. Ensure that the connectors on the
board’s edge are aligned properly with the slot connector.
4. Push the card into the slot firmly and evenly until it is fully seated in the slot connector.
5. Inspect the connection. If it does not appear to be correct, remove and reinstall the card.
6. Install the retaining screw.
7. Attach any required cables to the internal or external connectors.
Expansion Cards with PCI-to-PCI Bridges
If you add an expansion card with a PCI-to-PCI bridge to the system, you may encounter boot
problems. This happens because such a card essentially adds another PCI bus to the system, and
causes a renumbering of the PCI buses in the system. For example, if you add such a card to an
expansion slot on PCI bus 0:
♦ PCI bus 0 remains PCI bus 0
♦ The card becomes PCI bus 1
♦ PCI bus 1 becomes PCI bus 2
You must change the boot order in the SCSI Configuration Utility for the SCSI controllers on the
PCI buses to reflect the new PCI bus numbering. See System Setup for infor matio n on running and
using the SCSI Configuration Utility.
However, Windows NT will not use the boot order set by the SCSI Configuration Utility.
Windows NT always finds PCI bus 0 first. Ensure that your system’s primary boot device is on
PCI bus 0, and then use the SCSI Configuration Utility as needed to change boot order.
Assigning System Resources
Some expansion cards include a configuration diskette that you can use to reserve the system
resources required for the card. Other expansion cards do not include a diskette, but require that
you manually program the BIOS with the configuration information.
See System Setup for details on assigning system resources and configuring the BIOS for
expansion cards.
NOTE Treat non-compliant PCI cards and PCMCIA cards as ISA cards when assigning
system resources.
Adding Removable Disk Drives
The system supports up to four 3.5-inch removable disk drives in the disk drive bay. Each
removable disk drive has a Single Connection Attach (SCA) connector for connection to the disk
drive bay backplane. The SCSI address of each removable disk drive is assigned by the disk drive
bay backplane.
JBOD (for “just a bunch of disks”) disk drives are controlled by an integrated dual-channel Low
Voltage Differential Signaling (LVDS) Wide Ultra2 SCSI controller. The disk drive bay (and thus
each removable disk drive) is connected to the Wide Ultra2 SCSI controller via Channel B.
A single-channel RAID (for “redundant array of independent disks”) controller and an optional
SCSI Activity Fault-Tolerant Enclosure (SAF-TE) card control RAID disk drives. The RAID
controller is connected to the backplane of the disk drive bay. The SAF-TE card is installed on the
disk drive bay backplane.
CAUTION Only use disk drives purchased from Intergraph in the disk drive bay. This ensures
the drives meet the disk drive bay specifications.
See Chapter 2, “Servicing the System,” or System Setup for information on installing removable
disk drives in the disk drive bay.
37
Adding an Internal SCSI Peripheral Device
A CD-ROM drive, a floppy disk drive, and the system disk drive are installed in the peripheral
device bay. You can add an optional SCSI peripheral device to the peripheral device bay unless
one is already installed there.
Except for the floppy disk drive, integrated SCSI controllers control the devices installed in the
peripheral device bay. The CD-ROM drive is connected to the Narrow Ultra SCSI controller; the
system disk drive is connected to the Wide Ultra2 SCSI controller via Channel A. The optional
SCSI device can be connected to either controller, as appropriate for the type of device installed.
The following table describes the devices in the peripheral device bay:
Drive
Floppy disk drive External 3.50-inch x 1.0-inch N/A
CD-ROM drive External 5.25-inch x 1.6-inch Narrow Ultra SCSI
System disk drive Internal 5.25-inch x 1.6-inch Wide Ultra2 SCSI Channel A
Peripheral device External 5.25-inch x 1.6-inch As appropriate for the device
Access Maximum Capacity SCSI Bus
38
Remember the following when installing an optional SCSI peripheral device:
♦ The maximum speed of a SCSI bus is limited to the speed of the slowest device on that bus.
♦ Have the vendor’s documentation available to follow instructions for setting the SCSI ID,
enabling or disabling termination, installing device drivers when required, and configuring
other drive attributes.
♦ If you are installing a internal peripheral device that connects to an expansion card, see the
vendor’s documentation for installing the expansion card and required cables. See “Adding
Expansion Cards” for details.
♦ The length of the Wide Ultra2 SCSI cable is 30 inches (0.76 meters). The length of the
Narrow Ultra SCSI cable is 56 inches (1.4 meters).
See the following chapters for related information and important details:
♦ Chapter 6, “System Hardware,” for details on power supply cable connectors and pinouts.
♦ Chapter 7, “Peripherals,” for details on common internal devices and internal device cables.
To install a peripheral device in the available peripheral device bay:
1. Open the face panel as described in Chapter 1, “Accessing the Components.”
2. Loosen the thumbscrew on the locking plate near the top left corner of the peripheral device
bay.

Adding External SCSI Peripheral Devices
The system features integrated Narrow Ultra SCSI and Wide Ultra2 SCSI controllers. However,
only the Narrow Ultra SCSI controller has an external port. You can connect external singleended Narrow Ultra SCSI peripheral devices to this port. To connect external Wide Ultra or Wide
Ultra2 peripheral devices, you must install the appropriate SCSI controller as an expansion card.
NOTE Most SCSI controllers do not recognize a hard disk drive that was formatted using a
different brand of controller. For example, a hard disk drive formatted with an
Adaptec SCSI controller will not work with a Symbios SCSI controller. You must use
only Symbios-formatted hard disk drives with a Symbios SCSI controller.
SCSI Cable Lengths and Device Speeds
For each SCSI bus, the type of bus and the data clock speed of the fastest device on that bus
determine its maximum length. Knowing this, you can determine the maximum cable length you
can use to connect external SCSI devices to the system.
The following table provides a guide to maximum SCSI bus length. Note that bus width (for
example, Narrow versus Wi de) does not affect the maximum bus length.
Speed of the fastest
device on the bus
5 MHz (SCSI-1) 19.7 ft / 6 m 82 ft / 25 m 39.4 ft / 12 m
10 MHz (SCSI-2 or Fast) 9.8 ft / 3 m 82 ft / 25 m 39.4 ft / 12 m
20 MHz (Ultra or Fast20) 4.9 ft / 1.5 m 39.4 ft / 12 m 39.4 ft / 12 m
40 MHz (Ultra2 or Fast40) Not recommended Not specified 39.4 ft / 12 m
The total cable length on the system’s Narrow Ultra SCSI bus is the sum of the following:
♦ Narrow Ultra SCSI cable in the system−56 inches (1.4 meters)
♦ SCSI cable inside each internal device connected to the Narrow Ultra SCSI cable−typically 8
inches (0.2 meters) or less
♦ SCSI cable between the system and the first external device
♦ SCSI cable between each external device
Note that the maximum speed of a SCSI bus is limited to the speed of the slowest device on that
bus.
Single-ended bus Differential bus
Low-voltage
differential bus
SCSI Cable Quality
To ensure data integrity and optimum performance, do the following:
♦ Use only Intergraph Computer Systems SCSI cables. Cables from other vendors may not
provide adequate shielding.
♦ Use the shortest cables possible to connect SCSI devices to the system and to each other.
CAUTION You should try to minimize cable flexing during handling. SCSI cables should not
have any creased bends. Take care when installing or replacing cables to insure that
they do not contact sharp metal surfaces or become excessively bent or twisted.
SCSI IDs
By default, specific devices use the following SCSI IDs:
♦ System disk drive (standard) uses ID 0
♦ SCSI controller always uses ID 7
♦ CD-ROM drive uses ID 4
♦ Zip, Jaz, or tape drive (optional) uses ID 6
41
NOTE To easily determine the ID of each SCSI device on the system, restart the system.
When the BIOS screen displays, look for the list of SCSI devices and write down the
ID for each device.
Some SCSI devices feature push switches to set the ID, while others have DIP switches or
jumpers. See the vendor documentation for details on setting the ID.
SCSI Termination for External Devices
Follow the guidelines below for terminating SCSI devices:
♦ Enable termination on the last external device on the SCSI cable chain.
♦ Disable termination on all other external devices on the SCSI cable chain.
♦ Use only an active terminator on externally terminated devices.
Connecting an External SCSI Drive
To connect an external SCSI drive:
1. Connect one end of the external SCSI cable to the Narrow Ultra SCSI port on the back of the
system.
2. Connect the other end of the cable to the SCSI device.
42
3. Set the SCSI ID of the device to an unuse d number.
4. If the SCSI device is:
− The last or only device on the SCSI chain, enable SCSI termination
− Not the last or only device on the SCSI chain, disable SCSI termination
5. Ensure that the power switch on the device is in the off position, and then connect the power
cord to the device and then to an AC receptacle.
6. Turn on the power to the device and any other devices on the SCSI chain.
7. Start the system. If necessary, install the software drivers and configure the drive according to
the vendor’s instructions.
Changing SCSI Controller or Device Settings
You may need to use the SCSI Configuration Utility (PCI_CFG.EXE) to configure the operation of
SCSI peripherals connected to the integrated Symbios SCSI controllers. This utility enables you to
configure SCSI controllers, perform a low-level format on a SCSI hard disk drive, select boot
order, and verify media.
You may need to change SCSI controller parameters on a per-device basis under the following
conditions:
♦ If you are advised to do so by Intergraph Computer Systems technical support or instructed to
do so by the vendor documentation supplied with the SCSI device.
♦ If the SCSI device does not negotiate properly with the controller. This is common on older
drives.
♦ If you exceed the total cable length for connecting SCSI devices to the system, as specified in
the section, “Connecting an External SCSI Device,” in Chapter 1.
♦ If you connect non-Ultra or non-Wide Ultra2 SCSI external devices to the system.
For more information on using the SCSI Configuration Utility, see System Setup.

Sound Processor
The system’s on-board sound processor is the Ensoniq ES1371 AudioPCI processor. The ES1371
offers support for 64 voices, and is DirectX 5.0 and ACPI compliant. The on-board ES1371 may
be software disabled if an add-in audio processor is preferred. Line-in, line-out, and Mic-in jacks
are provided on the rear of the motherboard/chassis. Integrated onto the system board, the
processor is a complete, fully featured PC 97 compliant sound implementation. It has the
following specifications:
Feature
Audio Resolution 16-bit
MIDI/UART Mode Compatibility Roland MPU401
Bus Interface 16-bit PCI
CODEC Delta Sigma-based Windows Sound System
CODEC FIFO 16 Samples
FM Synthesizer Crystal internal FM synthesis
External Audio Inputs Microphone (Monaural), Stereo Line-In
Internal Audio Inputs Stereo FM Synthesis, Stereo Wave Data, Stereo CD,
Audio Outputs Stereo Line-Out
MIDI/Joystick MIDI In, MIDI Out, up to 4 fire buttons
ADPCM Audio Compression 4:1, 3:1, and 2:1
Sampling Rate Range 5 KHz - 44.1 KHz in 228 selectable steps
The Ensoniq ES1371 AudioPCI sound processor is configured entirely through I/O port accesses.
When the system is powered up, the hardware forces the Ensoniq ES1371 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 sound processor configurations and available
programmable settings.

A v ailable IRQs
IRQs 5 and 10 are available for assignment. If a non-Plug And Play compliant ISA card is
installed, set it to use either IRQ 5 or IRQ 10. In BIOS Setup, the selected IRQ must be set to
reserved.
Freeing IRQs
To free IRQs for use by an ISA device or a PCI device that uses drivers that do not comply with
the PCI 2.l specification, you can use the system BIOS to disable unuse d system ports.
To disable an unused system port:
1. Restart the system and press
2. Select Setup, and then select Peripheral Setup.
3. Select the port you want to disable (OnBoard Serial Port 1, OnBoard Serial Port 2, or
OnBoard Parallel Port).
4. Change the value of the setting to Disabled.
5. Save the changes and exit from BI OS Setup.
DEL when prompted to enter Setup.
PCI Devices
The system’s PCI expansion slots comply with the PCI 2.1 specification. Devices that comply
with the PCI 2.1 specification are fully plug-and-play. You do not have to configure them after
installation.
Some older PCI device drivers cannot share an interrupt, which is a violation of the PCI 2.1
specification. If you install a device that uses such a driver, you must free an IRQ for the device to
work in the system.
PCI to ISA Bus Interrupt Mapping
The system’s ISA bridge provides the sixteen conventional ISA interrupts, plus four interrupt
request pins for PCI peripheral interrupts (PIRQ0 through PIRQ3). For PC-AT architecture
compatibility reasons, the PCI interrupts are routed to the ISA interrupts within the ISA bridge.
The assertion of a PCI interrupt concludes in an ISA interrupt being asserted.
Bit 7 of each PIRQ registers enable (Low) or disable (High) the routing of the PIRQ to an ISA
interrupt. The lowest four bits (3:0) of each PIRQ register determines to which ISA interrupt the
PIRQ is routed.
You can map the PIRQs to the following ISA interrupts:
IRQs 5, 10, 11, 15
You can also map to IRQs 3, 4, 7, 12, and 14, but other devices are disabled if you do so.
Each PCI slot has four available interrupt lines: INTA, INTB, INTC, and INTD. These are
connected to the PCI interrupts, P IRQ0 through PIRQ3, as shown below:
61
Interrupt Line
INTA PIRQ0 PIRQ1 PIRQ2 PIRQ3 PIRQ0 P IRQ1 PIRQ2
INTB PIRQ1 PIRQ2 PIRQ3 PIRQ0 PIRQ1 PIRQ2 PIRQ3

You can assign the spare interrupt listed above to an ISA device. When you add a PCI device to
the system, the system BIOS automatically assigns the interrupt. However, at least one interrupt
must be available for the PCI bus.
When you add an ISA board, you must reserve the interrupt using the BIOS Setup utility and
jumpers on the expansion board. See the vendor documentation for the expansion board for
jumper and related information.
62
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 cha nnels.

J20
Disk Drive Bay
The disk drive bay includes the disk drive cage and a Small Computer Systems Interface (SCSI)
backplane. This assembly is always replaced as one unit.
The SCSI backplane is a Low Voltage Differential Signal (LVDS) SCSI compliant backplane. It
is designed to connect up to four SCSI devices to a system in which the backplane is installed.
These SCSI devices must use the Single Connection Attach (SCA)-2 connectors that incorporate
connections for power and status lines, as well as the signals comprising the wide SCSI bus.

SCSI drive connection is made through connectors J1 – 4. These are the only connectors on the
front of the backplane. Connection for an optional SCSI Accessible Fault-Tolerant Enclosure
(SAF-TE) card is through J18 , which is a 72-pin SIMM connector.
CAUTION J18 is designed to connect only to a SAF-TE card. Do not connect a single inline
memory module (SIMM) to this location.
J15 and J14 are the 68-pin SCSI connectors for connecting the backplane to an LVDS SCSI
controller. J15 is the input connector. J14 is only used to daisy-chain multiple disk drive bay
backplanes.
J16 and J17 provide power (+12V, +5V, Ground) to the backplane. Both connectors must be used
for proper operation.
J20 and J21 are auxiliary bus connectors used in multiple backplane configurations only. J9 is
used only in multiple backplane configurations and should not be installed.
U7-9 are the LVD SCSI termination circuits. These provide the bus termination necessary for
proper operation.

Jumper Settings
RAID systems, which use the Mylex RAID controller, do not use any jumpers on these headers.
The spin-up delay and SCSI ID settings are controlled by the RAID controller and SCSI
backplane, respectively.
Removable Disk Drive LEDs
Light-emitting diodes (LEDs) D1 thr ough D8 are visual activity indicat ors for the removable disk
drives installed in the disk drive bay. The LEDs are grouped in pairs above each slot in the disk
drive bay, and are visible behind the disk drive bay door.
Removable Disk Drive LEDs
The right LED above each removable disk drive flashes to show disk activity.
The left LED functions only when an optional SCSI Accessible Fault-Tolerant Enclosure
(SAF-TE) card is installed, and when the backplane is connected to a SAF-TE compliant SCSI
controller or RAID controller.
73
On a system with RAID disk drives, an optional SCSI Activity Fault-Tolerant Enclosure (SAF-TE)
card monitors the status of RAID disk drives. The SAF-TE card causes the left LED above each
disk drive to indicate RAID disk drive status, as follows:
Left LED Activity
Off No error
Steady on Disk drive rebuild stopped or disk drive is faulty
Steady blink (approx. 1 per second) Disk drive rebuild in progress
Fast steady blink (approx. 3 per second) Disk drive identification in progress
4 fast blinks, pause (repeats) Disk drive experienced a predicted fault
2 fast blinks, pause (repeats) Disk drive is a hot spare
Power Supply
The 300 Watt power supply has a manual switch for selecting either 115 VAC (90-132 VAC)
range or 230 VAC (180-264 VAC) range for domestic or oversea locations. The input frequency
is 47-63 Hz, single phase. Input current is 5 amps maximum for the 115 VAC range and 2.5 amps
for the 230 VAC range. At full load, the power supply has a minimum efficiency of 65 percent.
The power supply is enclosed in a case that includ es a fan to provide additional airflow through the
system.
The power supply has the following DC output specifications.

Hardware Monitoring and Power Management
GT RAX systems feature advanced hardware monitoring and power ma nagement capabilities.
These features help you save energy, prolong system life, and provide for future functionality, such
as remote system wakeup.
When used with InterSite Hardware Monitor software, these features enable you to keep track such
things as voltages, temperatures, and fan speeds. For more information on the items that can be
monitored on your system, refer to Hardware Monitor Help.
Resistive temperature sensors are located on the system board near the primary processor and the
expansion slots. These devices provide signals for reporting temperature readout data to the
InterSite Hardware Monitor software. The sensor at the expansion slots provides the signal for
76
controlling fan speed. The temperature sensors are part of the system board and are not field
replaceable.
The Power LED (next to the Power button) on the front of the base unit indicates the following
power states of the system:
LED
Power State System is... Explanation
Green Working On System is fully usable; power conservation is on a per-
device basis.
Yellow M echanical Off Off Very little power consumption. System can be turned
on manually by pressing the power button or remotely
using the Wake-on-LAN feature.
Off Physical Off Off No power consumption. The system is disconnected
from AC line power, or is indicating that one of the
supply voltages is not correct. The system requires
reconnection of power or correction of voltage problem
and returns to the Working state only after a full
shutdown and restart.
