on the serverboard), a VGA (monitor) port, two USB 2.0 ports, PS/2 mouse
and keyboard ports, a parallel port (X6DH8-G2 only) and two gigabit
Ethernet ports.

ATI Graphics Controller

The X6DH8-G2/X6DH8-XG2 features an integrated ATI video controller
based on the Rage XL graphics chip. Rage XL fully supports sideband
addressing and AGP texturing. This onboard graphics package can provide
a bandwidth of up to 512 MB/sec over a 32-bit graphics memory bus.

Other Features

Other onboard features that promote system health include onboard voltage
monitors, a chassis intrusion header, auto-switching voltage regulators,
chassis and CPU overheat sensors, virus protection and BIOS rescue.

1-3 Server Chassis Features

The SuperServer 7044H-82R/7044H-X8R/7044H-82 is a high-end, scaleable
server platform designed with today's most state-of-the-art features. The
following is a general outline of the main features of the SC743S1-R760/
SC743S1-650 server chassis.

System Power

7044H-82R/7044H-X8R: the SC743S1-R760 features a triple redundant
760W power supply that consists of three separate power supply modules.
These modules all share the load and run continuously. If any of the three
fail, the remaining two pick up the load and keep the system running without
interruption. A failed power supply module will illuminate the power fail
LED. The power supply modules are all hot-swappable, so you don't have
to power down the system to replace a module.

7044H-82: the SC743S1-650 features a single 650W power supply. Power
must be removed from the system before servicing or replacing this power
supply.

1-4

SUPERSERVER 7044H-82R/7044H-X8R/7044H-82 User's Manual

SCSI Subsystem

The SCSI subsystem supports up to eight 80-pin SCA Ultra320 SCSI hard
drives. Any standard 1" drives are supported. SCA = Single Connection
Attachment.) The SCSI drives are connected to a single-channel SCA
backplane with SAF-TE. The SCSI drives are also hot-swap units. A RAID
controller card can be used with the SCA backplanes to provide data secu­rity.

Note: The operating system you use must have RAID support to enable the
hot-swap capability of the SCSI drives.

Chapter 2

Server Installation

2-1 Overview

This chapter provides a quick setup checklist to get your SuperServer
7044H-82R/7044H-X8R/7044H-82 up and running. Following these steps in
the order given should enable you to have the system operational within a
minimum amount of time. This quick setup assumes that your system has
come to you with the processors and memory preinstalled. If your system
is not already fully integrated with a serverboard, processors, system
memory etc., please turn to the chapter or section noted in each step for
details on installing specific components. The 7044H-82R/7044H-X8R/
7044H-82 may be employed either as a tower or mounted in a rack as a 4U
rackmount chassis. If using it as a tower unit, please read the Server
Precautions in the next section and then skip ahead to Section 2-5.

2-2 Unpacking the System

You should inspect the box the system was shipped in and note if it was
damaged in any way. If the server itself shows damage you should file a
damage claim with the carrier who delivered it.

Decide on a suitable location for the SuperServer 7044H-82R/7044H-X8R/
7044H-82. It should be situated in a clean, dust-free area that is well
ventilated. Avoid areas where heat, electrical noise and electromagnetic
fields are generated. You will also need it placed near a grounded power
outlet. Be sure to read the Rack and Server Precautions in the next section.

2-3 Preparing for Setup

The box the system was shipped in may include two sets of rail assemblies, two
rail mounting brackets and mounting screws needed for installing the system into
a rack (optional kit). Follow the steps in the order given to complete the instal­lation process in a minimum amount of time. Please read this section in its
entirety before you begin the installation procedure outlined in the sections that
follow.

2-2

SUPERSERVER 7044H-82R/7044H-X8R/7044H-82 User's Manual

Choosing a Setup Location

- Leave enough clearance in front of the system to enable you to open

the front door completely (~25 inches).

- Leave approximately 30 inches of clearance in the back of the system

to allow for sufficient airflow and ease in servicing.

-This product is for installation only in a Restricted Access Location (dedi­cated equipment rooms, service closets and the like).

Rack Precautions

- Ensure that the leveling jacks on the bottom of the rack are fully

extended to the floor with the full weight of the rack resting on them.

- In single rack installation, stabilizers should be attached to the rack.

- In multiple rack installations, the racks should be coupled together.

- Always make sure the rack is stable before extending a component

from the rack.

- You should extend only one component at a time - extending two or

more simultaneously may cause the rack to become unstable.

Server Precautions

- Review the electrical and general safety precautions in Chapter 4.

- Determine the placement of each component in the rack before you

install the rails.

- Install the heaviest server components on the bottom of the rack

first, and then work up.

- Use a regulating uninterruptible power supply (UPS) to protect the
server from power surges, voltage spikes and to keep your
system operating in case of a power failure.

- Allow the hot plug SCSI drives and power supply units to cool before

touching them.

- Always keep the rack's front door and all panels and components on

the servers closed when not servicing to maintain proper cooling.

Rack Mounting Considerations

Ambient Operating Temperature

If installed in a closed or multi-unit rack assembly, the ambient operating
temperature of the rack environment may be greater than the ambient
temperature of the room. Therefore, consideration should be given to
installing the equipment in an environment compatible with the manufacturer’s
maximum rated ambient temperature (Tmra).

Reduced Airflow

Equipment should be mounted into a rack so that the amount of airflow
required for safe operation is not compromised.

Mechanical Loading

Equipment should be mounted into a rack so that a hazardous condition does
not arise due to uneven mechanical loading.

Circuit Overloading

Consideration should be given to the connection of the equipment to the power
supply circuitry and the effect that any possible overloading of circuits might have
on overcurrent protection and power supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.

Reliable Ground

A reliable ground must be maintained at all times. To ensure this, the rack itself
should be grounded. Particular attention should be given to power supply con­nections other than the direct connections to the branch circuit (i.e. the use of
power strips, etc.).

2-4 Installing the System into a Rack

This section provides information on installing the system into a rack unit. Rack
installation requires the use of the optional rackmount kit [CSE-PT26(B)]. If the
system has already been mounted into a rack or if you are using it as a tower,
you can skip ahead to Sections 2-5 and 2-6. There are a variety of rack units
on the market, which may mean the assembly procedure will differ slightly. The
following is a guideline for installing the server into a rack with the rack
rails provided in the rackmount kit. You should also refer to the installation
instructions that came with the rack unit you are using.

Identifying the Sections of the Rack Rails

The optional rackmount kit (CSE-PT26 or CSE-PT26B - black) includes two rack
rail assemblies. Each of these assemblies consist of three sections: an inner
fixed chassis rail that secures to the chassis, an outer rack rail that secures
directly to the rack itself and two rail brackets, which also attack to the rack (see
Figure 2-1.) The inner and outer rails must be detached from each other to
install.

To remove the inner chassis rail, pull it out as far as possible - you
should hear a "click" sound as a locking tab emerges from inside the rail
assembly and locks the inner rail. Depress the locking tab to pull the
inner rail completely out. Do this for both assemblies (one for each side).

Installing the Chassis Rails

You will need to remove the top cover and the feet to add rack rails to the
chassis. First, remove the top and right covers (top and left covers when standing
as a tower chassis) by first removing the screws that secure them to the chassis.
Depress the button on the top (side if tower) of the chassis to release the cover
and then pull the cover off. Then unscrew the four feet and remove them from the
chassis (see Figure 2-2).

You can now attach rack rails to the top and bottom (now the sides) of the
chassis. First add the rack handles. Then position the inner chassis rail
sections you just removed along the side of the chassis making sure the screw
holes line up. Note that these two rails are left/right specific. Screw the rail
securely to the side of the chassis (see Figure 2-3). Repeat this procedure for
the other rail on the other side of the chassis. You will also need to attach the
rail brackets when installing into a telco rack.

Locking Tabs: As mentioned, the chassis rails have a locking tab, which serves
two functions. The first is to lock the server into place when installed and pushed
fully into the rack, which is its normal position. Secondly, these tabs also lock
the server in place when fully extended from the rack. This prevents the server
from coming completely out of the rack when you pull it out for servicing.

Figure 2-2. Preparing to Install the Chassis Rails

SUPERSERVER 7044H-82R/7044H-X8R/7044H-82 User's Manual

Installing the Rack Rails

Determine where you want to place the SuperServer 7044H-82R/7044H­X8R/7044H-82 in the rack. (See Rack and Server Precautions in Section 2-

3.) Position the fixed rack rail/sliding rail guide assemblies at the desired
location in the rack, keeping the sliding rail guide facing the inside of the
rack. Screw the assembly securely to the rack using the brackets pro­vided. Attach the other assembly to the other side of the rack, making sure
both are at the exact same height and with the rail guides facing inward.

Figure 2-4. Installing the Server into a Rack

Installing the Server into the Rack

You should now have rails attached to both the chassis and the rack unit. The
next step is to install the server into the rack. You should have two brackets in
the rack mount kit. Install these first keeping in mind that they are left/right
specific (marked with "L" and "R"). Then, line up the rear of the chassis rails with
the front of the rack rails. Slide the chassis rails into the rack rails, keeping the
pressure even on both sides (you may have to depress the locking tabs when
inserting).

When the server has been pushed completely into the rack, you should hear the
locking tabs "click". Finish by inserting and tightening the thumbscrews that
hold the front of the server to the rack (see Figure 2-4).

2-5 Checking the Serverboard Setup

After setting up the the system, you will need to open the unit to make sure the
serverboard is properly installed and all the connections have been made.

1. Accessing the inside of the system (see Figure 2-5)

[If rack mounted, first release the retention screws that secure the unit
to the rack. Grasp the two handles on either side and pull the unit
straight out until it locks (you will hear a "click").] There are two screws
that secure the cover to the chassis - remove these first. Depress the
button on the top (side if tower) of the chassis to release the cover.
You can then lift the cover from the chassis to gain full access to the
inside of the server.

2. Check the CPUs (processors)

You should have one or two processors already installed into the
serverboard. Each processor should have its own heatsink attached.
See Chapter 5 for instructions on processor installation.

3. CPU clock ratio setting

The CPU speed should be automatically detected. If not, you will need to
set the correct speed with the BIOS Setup utility. See the Frequency
Ratio setting in BIOS (Chapter 7) to set the processor speed.

4. Check the system memory

Your server may have come with system memory already installed. Make
sure all DIMMs are fully seated in their slots. For details on adding
system memory, refer to Chapter 5.

5. Installing add-on cards

If desired, you can install add-on cards to the system. See Chapter 5 for
details on installing PCI add-on cards.

6. Check all cable connections and airflow

Make sure all power and data cables are properly connected and not blocking
the chassis airflow. See Chapter 5 for details on cable connections.

Chapter 2: Server Installation

2-9

2-6 Checking the Drive Bay Setup

Next, you should check to make sure the peripheral drives and the SCSI
drives and SCA backplane have been properly installed and all connections
have been made.

1. Accessing the drive bays

All drives can be accessed from the front of the server. For servicing
the CD-ROM, IDE hard drives and floppy drives, you will need to remove
the top/left chassis cover. The SCSI disk drives can be installed and
removed from the front of the chassis without removing any chassis
covers.

2. Installing components into the 5.25" drive bays

To install components into the 5.25" drive bays, you must first remove the
top/left chassis cover as described in the previous section. Refer to
Chapter 6 for details.

SUPERSERVER 7044H-82R/7044H-X8R/7044H-82 User's Manual

3. Installing CD-ROM and floppy disk drives

Refer to Chapter 6 if you need to reinstall a CD-ROM and/or floppy disk
drive to the system.

4. Check the SCSI disk drives

Depending upon your system's configuration, your system may have one
or more drives already installed. If you need to install SCSI drives, please
refer to Chapter 6.

5. Check the airflow

Airflow is provided by four hot-swap 8-cm chassis fans working in conjunction
with an air shroud. Two 8-cm exhaust fans are also mounted at the rear
of the chassis. The system component layout was carefully designed to
promote sufficient airflow through the chassis. Also note that all power
and data cables have been routed in such a way that they do not block
the airflow generated by the fans. Keep this in mind when you reroute
them after working on the system.

6. Supplying power to the system

The last thing you must do is to provide input power to the system. Plug the
power cord from the power supply unit into a high-quality power strip that offers
protection from electrical noise and power surges. It is recommended that you
use an uninterruptible power supply (UPS). Finally, depress the power on
button on the front of the chassis.

System Interface

3-1 Overview

The control panel on the 7044H-82R/7044H-X8R/7044H-82 has several LEDs
and two buttons. There are also two LEDs on each SCSI drive carrier and
the Ethernet ports. These LEDs keep you constantly informed of the overall
status of the system and the activity and health of specific components.

3-2 Control Panel Buttons

There are two push-buttons located on the front of the chassis. These are
(in order from left to right) a power on/off button and a reset button.

z POWER: This is the main power button, which is used to apply or turn
off the main system power. Turning off system power with this button
removes the main power but keeps standby power supplied to the system.

z RESET: Use the reset button to reboot the system.

3-3 Control Panel LEDs

The control panel located on the front of the SC743S1-R760/SC743S1-650
chassis has six LEDs that provide you with critical information related to
different parts of the system. This section explains what each LED indi­cates when illuminated and any corrective action you may need to take.

z Power: Indicates power is being supplied to the system's power

supply. This LED should normally be on when the system is operating.

z HDD: Indicates IDE channel activity. On the SC743S1-R760/SC743S1-
650, this LED indicates SCSI drive activity when flashing.

z NIC1: Indicates network activity on LAN1 when flashing.

z NIC2: Indicates network activity on LAN2 when flashing.

z Overheat/Fan Fail: When this LED flashes, it indicates a fan failure.

When on continuously it indicates an overheat condition, which may be
caused by cables obstructing the airflow in the system or the ambient room
temperature being too warm. Check the routing of the cables and make
sure all fans are present and operating normally. You should also check to
make sure that the chassis covers are installed. Finally, verify that the
heatsinks are installed properly (see Chapter 5). This LED will remain flash­ing or on as long as the indicated condition exists.

Chapter 3: System Interface

3-3

z Power Fail: Indicates a power supply module has failed. This should
be accompanied by an audible alarm. A backup power supply module will
take the load and keep the system running but the failed module will need to
be replaced. Refer to Chapter 6 for details on replacing the power supply.
This LED should be off when the system is operating normally.

3-4 SCSI Drive LEDs

Each SCSI drive carrier has two LEDs.

z Green: When illuminated, the green LED on the front of the SCSI drive

carrier indicates drive activity. A connection to the SCSI SCA backplane
enables this LED to blink on and off when that particular drive is being
accessed.

z Red: A SAF-TE compliant backplane is needed to activate the red
LEDs, which indicate a drive failure. Please refer to Chapter 6 for instruc­tions on replacing failed SCSI drives.

3-5 LAN (Ethernet) Port LEDs

The LAN Ethernet port(s) (located beside the VGA port) each have a yellow and
a green LED. The yellow (left) LED indicates activity while the other (right) LED
may be green, orange or off to indicate the speed of the connection. See the
tables below for the functions associated with these LEDs.

4-1 Electrical Safety Precautions

!

Basic electrical safety precautions should be followed to protect yourself
from harm and the SuperServer 7044H-82R/7044H-X8R/7044H-82 from dam­age:

z Be aware of the locations of the power on/off switch on the chassis

as well as the room's emergency power-off switch, disconnection
switch or electrical outlet. If an electrical accident occurs, you can
then quickly remove power from the system.

z Do not work alone when working with high voltage components.

z Power should always be disconnected from the system when removing

or installing main system components, such as the serverboard,
memory modules and the CD-ROM and floppy drives (not necessary
for SCSI drives). When disconnecting power, you should first power
down the system with the operating system and then unplug the
power cords of all the power supply units in the system.

z When working around exposed electrical circuits, another person who

is familiar with the power-off controls should be nearby to switch off
the power if necessary.

z Use only one hand when working with powered-on electrical

equipment. This is to avoid making a complete circuit, which will
cause electrical shock. Use extreme caution when using metal tools,
which can easily damage any electrical components or circuit boards
they come into contact with.

z Do not use mats designed to decrease electrostatic discharge as

protection from electrical shock. Instead, use rubber mats that have
been specifically designed as electrical insulators.

4-2 General Safety Precautions

Follow these rules to ensure general safety:

z Keep the area around the SuperServer 7044H-82R/7044H-X8R/7044H-

82 clean and free of clutter.

z The SuperServer 7044H-82R/7044H-X8R/7044H-82 weighs

approximately 70/64 lbs. (31.8/29.1 kg.) when fully loaded. When
lifting the system, two people at either end should lift slowly with their
feet spread out to distribute the weight. Always keep your back
straight and lift with your legs. Don't use the handles to lift the
chassis; the handles should only be used to pull the server out of the
rack.

z Place the chassis top cover and any system components that have been

removed away from the system or on a table so that they won't accidentally
be stepped on.

z While working on the system, do not wear loose clothing such as neckties

and unbuttoned shirt sleeves, which can come into contact with electrical
circuits or be pulled into a cooling fan.

z Remove any jewelry or metal objects from your body, which are excellent

metal conductors that can create short circuits and harm you if they come

!

z The power supply power cord must include a grounding plug and must

be plugged into grounded electrical outlets.

z Serverboard Battery: CAUTION - There is a danger of explosion if the

onboard battery is installed upside down, which will reverse its
polarities (see Figure 4-1). This battery must be replaced only with
the same or an equivalent type recommended by the manufacturer.
Dispose of used batteries according to the manufacturer's instructions.

z CD-ROM Laser: CAUTION - this server may have come equipped with a CD-

ROM drive. To prevent direct exposure to the laser beam and hazardous
radiation exposure, do not open the enclosure or use the unit in any
unconventional way.

Chapter 4: System Safety

4-3 ESD Precautions

Electrostatic discharge (ESD) is generated by two objects with different
electrical charges coming into contact with each other. An electrical
discharge is created to neutralize this difference, which can damage electronic
components and printed circuit boards. The following measures are generally
sufficient to neutralize this difference before contact is made to protect your
equipment from ESD:

z Use a grounded wrist strap designed to prevent static discharge.

z Keep all components and printed circuit boards (PCBs) in their antistatic

bags until ready for use.

z Touch a grounded metal object before removing the board from the antistatic
bag.

z Do not let components or PCBs come into contact with your clothing,
which may retain a charge even if you are wearing a wrist strap.

z Handle a board by its edges only; do not touch its components, peripheral
chips, memory modules or contacts.

z When handling chips or modules, avoid touching their pins.

z Put the serverboard and peripherals back into their antistatic bags when

not in use.

z For grounding purposes, make sure your computer chassis provides
excellent conductivity between the power supply, the case, the mounting
fasteners and the serverboard.

!

into contact with printed circuit boards or areas where power is
present.

z After accessing the inside of the system, close the system back up

and secure it to the rack unit with the retention screws after ensuring
that all connections have been made.

Advanced Serverboard Setup

This chapter covers the steps required to install processors and heatsinks
to the X6DH8-G2/X6DH8-XG2 serverboard, connect the data and power
cables and install add-on cards. All serverboard jumpers and connections
are described and a layout and quick reference chart are included in this
chapter. Remember to close the chassis completely when you have fin­ished working on the serverboard to protect and cool the system.

5-1 Handling the Serverboard

Static electrical discharge can damage electronic components. To prevent
damage to printed circuit boards, it is important to handle them very care­fully (see Chapter 4). Also note that the size and weight of the serverboard
can cause it to bend if handled improperly, which may result in damage. To
prevent the serverboard from bending, keep one hand under the center of
the board to support it when handling. The following measures are gener­ally sufficient to protect your equipment from static discharge.

Precautions

• Use a grounded wrist strap designed to prevent static discharge.

• Touch a grounded metal object before removing any board from its anti­static bag.

• Handle a board by its edges only; do not touch its components, periph­eral chips, memory modules or gold contacts.

• When handling chips or modules, avoid touching their pins.

• Put the serverboard, add-on cards and peripherals back into their anti­static bags when not in use.

Unpacking

The serverboard is shipped in antistatic packaging to avoid static damage.
When unpacking the board, make sure the person handling it is static pro­tected.

5-3 Connecting Cables

Now that the processors are installed, the next step is to connect the
cables to the serverboard. These include the data (ribbon) cables for the
peripherals and control panel and the power cables.

Connecting Data Cables

The ribbon cables used to transfer data from the peripheral devices have
been carefully routed in preconfigured systems to prevent them from block­ing the flow of cooling air that moves through the system from front to back.
If you need to disconnect any of these cables, you should take care to keep
them routed as they were originally after reconnecting them (make sure the
red wires connect to the pin 1 locations). If you are configuring the sys­tem, keep the airflow in mind when routing the cables.

The following data cables (with their serverboard connector locations noted)
should be connected. See the serverboard layout figure in this chapter for
connector locations.

z Ultra320 LVD SCSI cables (JA1)

z CD-ROM cable (JIDE2)

z Floppy drive cable (JFFD1)

z Control Panel cable (JF1, see next page)

z USB cable (JUSB2)

Connecting Power Cables

The X6DH8-G2/X6DH8-XG2 has a 24-pin primary power supply connector
designated JPW1 for connection to the ATX power supply. Connect the
appropriate connector from the power supply to the JPW1 connector to
supply power to the serverboard. The 12V 8-pin processor power connec­tor at JPW3 and the 12V 4-pin power connector at JPW2 must also both be
connected to your power supply. See the Connector Definitions section in
this chapter for power connector pin definitions.

Connecting the Control Panel

JF1 contains header pins for various front control panel connectors. See
Figure 5-2 for the pin locations of the various front control panel buttons
and LED indicators. Please note that even and odd numbered pins are on
opposite sides of each header.

All JF1 wires have been bundled into single ribbon cable to simplify their
connection. Make sure the red wire plugs into pin 1 as marked on the
board. The other end connects to the Control Panel printed circuit board,
located just behind the system status LEDs in the chassis.

5-5 Installing Memory

Note: Check the Supermicro web site for recommended memory modules:

http://www.supermicro.com/support/resources/

CAUTION

Exercise extreme care when installing or removing DIMM modules

to prevent any possible damage. Also note that the memory is

interleaved to improve performance (see step 1).

DIMM Installation (See Figures 5-4 and 5-5)

1. Insert the desired number of DIMMs into the memory slots, starting with
Bank 1. The memory scheme is interleaved so you must install two
modules at a time, beginning with DIMM A1 and DIMM B1 (Bank1), and
so on.

2. Insert each DIMM module vertically into its slot. Pay attention to the
notch along the bottom of the module to prevent inserting the DIMM
module incorrectly.

3. Gently press down on the DIMM module until it snaps into place in the
slot. Repeat for all modules (see step 1 above).

*A parallel port is included on the X6DH8-G2 (7044H-82R/7044H-82) only.

1. PCI slots

The X6DH8-G2 supports two PCI-Express x8 slots, one PCI-Express x4
slot, one 64-bit 133 MHz PCI-X slot and two 64-bit 100 MHz PCI-X slots.

The X6DH8-XG2 supports one PCI-Express x8 slot, three 64-bit 133 MHz
PCI-X slots and two 64-bit 100 MHz PCI-X slots.

The SC743S1-R760/SC743S1-650 chassis allows all six slots to be popu­lated with standard size (full height, full length) cards.

2. PCI card installation

Before installing a PCI add-on card, make sure you install it into a slot that
supports the speed of the card (see step 1 and refer to the motherboard
layout diagram). Begin by swinging the release tab on the I/O back panel
shield out to the left for the PCI slot. Insert the PCI card into the correct
slot on the serverboard, pushing down with your thumbs evenly on both
sides of the card. Finish by pushing the release tab back to its original
(locked) position. Follow this procedure when adding a card to other
slots.

Explanation of
Jumpers

To modify the operation of the
serverboard, jumpers can be
used to choose between
optional settings. Jumpers
create shorts between two pins
to change the function of the
connector. Pin 1 is identified
with a square solder pad on
the printed circuit board. See
the serverboard layout pages
for jumper locations.

Note: On two pin jumpers,
"Closed" means the jumper is on
and "Open" means the jumper is
off the pins.

CMOS Clear

JBT1 is used to clear CMOS (which will also clear any passwords). In­stead of pins, this jumper consists of contact pads to prevent accidentally
clearing the contents of CMOS.

On the X6DH8-G2/X6DH8-XG2, the CMOS Clear contact pads are located
between the floppy drive header and the South Bridge chip (see Figure 5-

6.
To clear CMOS,

1) First power down the system and unplug the power cord(s)

2) With the power disconnected, short the CMOS pads with a metal object
such as a small screwdriver

3) Remove the screwdriver (or shorting device)

4) Reconnect the power cord(s) and power on the system.

Note: Do not use the PW_ON connector to clear CMOS.

Connections

Note the following when connecting the floppy and hard disk drive cables:

• The floppy disk drive cable has seven twisted wires.

• A red mark on a wire typically designates the location of pin 1.

• A single floppy disk drive ribbon cable has 34 wires and two connectors
to provide for two floppy disk drives. The connector with twisted wires
always connects to drive A, and the connector that does not have
twisted wires always connects to drive B.

• The 80-wire ATA100/66 IDE hard disk drive cable that came with your
system has two connectors to support two drives. This special cable
should be used to take advantage of the speed this new technology
offers. The blue connector connects to the onboard IDE connector inter­face and the other connector(s) to your hard drive(s). Consult the docu­mentation that came with your disk drive for details on actual jumper
locations and settings for the hard disk drive.

Chapter 6

Advanced Chassis Setup

This chapter covers the steps required to install components and perform
simple maintenance on the SC743S1-R760/SC743S1-650 chassis. Follow­ing the component installation steps in the order given will eliminate most
common problems. If some steps are unnecessary, skip ahead to the step
that follows. Refer to Chapter 2 for instructions on installing the system as
a 4U rackmount.

Tools Required

The only tool you will need is a Philips screwdriver.

6-1 Static-Sensitive Devices

Static electrical discharge can damage electronic components. To prevent
damage to any printed circuit boards (PCBs), it is important to handle them
very carefully. The following measures are generally sufficient to protect your
equipment from static discharge.

Precautions

• Use a grounded wrist strap designed to prevent static discharge.

• Touch a grounded metal object before removing any board from its anti­static bag.

• Handle a board by its edges only; do not touch its components, peripheral
chips, memory modules or gold contacts.

• When handling chips or modules, avoid touching their pins.

• Put the serverboard, add-on cards and peripherals back into their anti­static bags when not in use.

• For grounding purposes, make sure your computer chassis provides ex­cellent conductivity between the power supply, the case, the mounting
fasteners and the serverboard.

Unpacking

The serverboard is shipped in antistatic packaging. When unpacking the
board, make sure the person handling it is static protected.

The front control panel must be connected to the JF1 connector on the
serverboard to provide you with system status and alarm indications. A
ribbon cable has bundled these wires together to simplify this connection.
Connect the cable from JF1 on the serverboard (making sure the red wire
plugs into pin 1) to the appropriate comnnector on the front control panel
PCB (printed circuit board). Pull all excess cabling over to the control
panel side of the chassis. The LEDs on the control panel inform you of
system status - see Figure 6-2 for details. See Chapter 5 for details on JF1.

6-3 System Fans

Four 8-cm chassis cooling fans (located in the center of the chassis) pro­vide cooling airflow while two 8-cm exhaust fans expel hot air from the
chassis. The chassis is also fitted with an air shroud to concentrate the
flow of cooling air over the areas of highest generated heat. The fans
should all be connected to headers on the serverboard (see Chapter 5).
The power supply module also has a cooling fan.

Fan Failure

Under normal operation, all four chassis fans, both exhaust fans and the
power supply fan run continuously. The four chassis fans and the two
exhaust fans are hot-swappable and can be replaced without powering
down the system.

Replacing Chassis Cooling Fans

1. Identifying the failed fan

To locate and replace a failed chassis fan, begin by removing the top/left
chassis cover (see Chapter 2 for details on removing the cover).

2. Removing a hot-plug fan housing
Depress the locking tab on a chassis cooling fan and pull the unit straight
out by the handle (see Figure 6-3). The fan wiring for these fans has been
designed to detach automatically.

3. Installing a new system fan

Replace the failed fan with an identical one (Supermicro p/n FAN-0072).
Install it in (and then reassemble) the fan housing, then plug the housing
back into its slot; it should click into place when fully inserted. Check
that the fan is working then replace the top/left side chassis panel.

Removing the air shroud

Under most circumstances you will not need to remove the air shroud to
perform any service on the system. However, if you wish to temporarily
remove it (the air shroud sould always be in place when the system is
operating), please follow this procedure.

Begin by depressing the tabs at the front and rear of the shroud to
unlock it, then lift it up and out of the chassis (see Figure 6-4). To
reinstall, simply position the air shroud in its proper place and push it in
until you hear it click.

1. Removing a hot-plug SCSI drive carrier

The eight SCSI drive carriers are all easily accessible at the front of the
chassis. The SCSI drives are hot-pluggable, meaning they can be removed
and installed without powering down the system. To remove a carrier, first
push the release button located beside the drive LEDs. Swing the handle
fully out and use it to pull the unit straight out from the chassis(see
Figure 6-5).

Note: Your operating system must have RAID support to enable the hot­plug capability of the SCSI drives.

2. Mounting a SCSI drive in a drive carrier

The SCSI drives are mounted in drive carriers to simplify their installation
and removal from the chassis. These carriers also help promote proper
airflow for the SCSI drive bays. For this reason, even empty carriers
without SCSI drives installed must remain in the chassis. To add a new
SCSI drive, install a drive into the carrier with the printed circuit board
side toward the carrier so that the mounting holes align with those in the
carrier. Secure the drive to the carrier with two screws on each side,
as shown in Figure 6-6.

6-4 Drive Bay Installation

SCSI Drives

Eight SCSI drives may be housed in the SC743S1-R760/SC743S1-650 chas­sis. The SCSI drive IDs are preconfigured as 0 through 7 in order from
bottom to top (tower configuration) or from left to right (if rackmounted).

Note: You must use standard 1" high, 80-pin SCA SCSI drives in the
SuperServer 7044H-82R/7044H-X8R/7044H-82.

Use extreme caution when working around the SCSI
backplane. Do not touch the backplane with any metal
objects and make sure no ribbon cables touch the
backplane or obstruct the airflow.

!

Important: Regardless of how many SCSI hard drives
are installed, all SCSI drive carriers must remain in the
drive bays to promote proper airflow.

Figure 6-5. Removing a SCSI Drive Carrier

3. SCSI backplane

All eight SCSI drives plug into a single SCSI backplane, which provides
Ultra320 single-channel operation for all eight SCSI drives. A ribbon cable
from JA1 on the serverboard should be connected to the IN connector on
the SCSI backplane. There are also two power connectors on the
backplane that must be connected. See Figure 6-7 for the locations of
backplane connectors - the reverse side of the backplane has five
connectors that the SCSI drives plug into when inserted with a SCSI drive
carrier or mobile rack.

Installing Components in the 5.25" Drive Bays

1. Drive bay configuration

The 7044H-82R/7044H-X8R/7044H-82 has two 5.25" drive bays. Compo­nents such as an extra floppy drive, IDE hard drives or CD-ROM drives
can be installed into these 5.25" drive bays.

2. Mounting components in the drive bays

First power down the system and then remove the top/left chassis cover
to access the drive components. With the cover off, remove the two or
four screws that secure the drive carrier to the chassis (one side only)
then push the entire empty drive carrier out from the back.

Adding a CD-ROM drive: remove the guide plates (one on each side) from
the empty drive carrier and screw them into both sides of the CD-ROM
drive using the holes provided. Then slide the CD-ROM into the bay and
secure it to the chassis with the drive carrier screws you first removed.
Attach the power and data cables to the drive. Replace the top/left
chassis cover before restoring power to the system.

Adding an IDE or floppy drive: to add one of these drives, install it into
one of the removed empty drive carriers with the printed circuit board
side toward the carrier so that the drive's mounting holes align with those
in the carrier. Secure the drive to the carrier with four screws then slide
the assembly into the bay and secure it to the chassis with the drive
carrier screws you first removed. Attach the power and data cables to
the drive. Replace the top/left chassis cover before restoring power to
the system.

Note: A red wire typically designates the location of pin 1. You should
keep the drive carriers inserted in any unused drive bays to reduce EMI
and noise and to facilitate the airflow inside the chassis.

6-5 Power Supply: 7044H-82R/7044H-X8R

The 7044H-82R/7044H-X8R has a triple redundant 760 watt redundant
cooling power supply that consists of three 380W power modules. All
three modules are active and share the load of the system (up to 760W
max.). If any of the three modules fail, the other two will continue to
provide up to 760W of power and allow the system to continue running
without interruption.

The power supply modules have an auto-switching capability that enable
them to automatically sense and operate with 100 or 240 volt inputs. The
power modules are PFC (Power Factor Correction) compliant.

Power Supply Failure

If a power supply module fails, an LED in the control panel as well as
one on the back of the failed power module will illuminate to notify you of
a power failure.

Replacing the Power Supply

1. Accessing the power supply

You do not need to power down the system to replace a power module
on the 7044H-82R/7044H-X8R. Power supply modules can be removed
from the back of the chassis; access to the inside is unnecessary.

2. Removing the power supply

First, unplug the power cord from the failed power supply module. Then
press the locking tab on the module and pull the unit completely out.

3. Installing a new power supply module

Replace the failed unit with another unit having the exact same part
number (PWS-0050M). Gently but firmly push the new unit all the way
into the open bay. Secure it to the chassis using the locking tab. Finish
by replacing the chassis left/top cover and then plugging the power cord
back into the new module you just added.

Chapter 6: Advanced Chassis Setup

6-11

6-6 Power Supply: 7044H-82

The SuperServer 7044H-82 has a single 650 watt power supply. This
power supply has an auto-switching capability, which enables it to auto­matically sense and operate at a 100V or 240V input voltage.

Power Supply Failure

If the power supply unit fails, the system will shut down and you will need
to replace the power supply unit. Replace with the same model - SP650-RP
(p/n PWS-0056), which can be ordered directly from Supermicro (see Con­tact Information in the Preface). As there is only one power supply unit in
the 7044H-82, the server must be powered down before removing and/or
replacing the power supply for whatever reason.

Replacing the Power Supply

1. Removing the power supply

First turn the power switch on the control panel off, then unplug the
power cord from the system. Then, unplug the power cord from the
failed power supply module. Finish by pressing the locking tab on the
module and pull the unit completely out.

2. Installing a new power supply

Replace the failed unit with another unit having the exact same part
number (PWS-0056). Gently but firmly push the new unit all the way into
the open bay. Secure it to the chassis using the locking tab. Finish by
replacing the chassis left/top cover and then plugging the power cord
back into the new module you just added.

Chapter 7

BIOS

7-1 Introduction

This chapter describes the Phoenix BIOS™ Setup utility for the X6DH8-G2/
X6DH8-XG2. The Phoenix ROM BIOS is stored in a flash chip and can be
easily upgraded using a floppy disk-based program. Due to periodic changes
in the BIOS, some settings may have been added or deleted that might not
yet be recorded in this manual. Please refer to the Manual Download area
of the Supermicro web site (www.supermicro.com) for any such changes.

Starting the Setup Utility

To enter the BIOS Setup Utility, hit the <Delete> key while the system is
booting-up. (In most cases, the <Delete> key is used to invoke the BIOS setup
screen. There are a few cases when other keys are used, such as <F1>,
<F2>, and so on.)

Each main BIOS menu option is described in this manual. The Main BIOS
screen has two main frames. The left frame displays all the options that can
be configured. “Grayed-out” options cannot be configured. The right frame
displays the key legend. Above the key legend is an area reserved for a
text message. When an option is selected in the left frame, it is highlighted
in white. Often a text message will accompany it. (Note: BIOS has default
text messages built in. Supermicro retains the option to include, omit, or
change any of these text messages.) Options printed in Bold are the
default settings.

The BIOS setup/utility uses a key-based navigation system called hot keys.
Most of these hot keys (<F1>, <F10>, <Enter>, <ESC>, <Arrow> keys, etc.)
can be used at any time during the setup navigation process.

Note: fan speed is controlled by the "Fan Speed Control Modes" setting
in BIOS. The recommended setting for the 7044H-82R/7044H-X8R/7044H-

82 is "3-pin (Server)" Loading the BIOS default settings may change this

setting. Therefore, if you do load BIOS defaults, you should reenter BIOS
setup and change this setting back to "3-pin (Server)", then save and
exit (see page 7-18).

Fan Speed Control Modes

This feature allows the user to decide how the system controls the speeds
of the onboard fans. If the option is set to "3-pin", the fan speed is con­trolled based upon the CPU die temperature. When the CPU die temperature
is higher, the fan speed will be higher as well. If the option is set to "4-pin",
the fan speed will be controlled by the Thermal Management Settings pre­configured by the user at this feature. Select "3-pin" if your chassis came
with 3-pin fan headers. Select "4-pin" if your chassis came with 4-pin fan
headers. Select "Workstation" if your system is used as a Workstation.
Select "Server" if your system is used as a Server. Select "Disable" to
disable the fan speed control function to allow the onboard fans to run at
the full speed (12V) at all time. The options are Disable, 3-pin (Server),
3-pin (Workstation), 4-pin (Server) and 4-pin (Workstation).

The recommended setting for the 7044H-82R/7044H-X8R/7044H-82 is "3-

Appendix A: BIOS POST Codes

A-1

This section lists the POST (Power On Self Test) codes for the PhoenixBIOS. POST
codes are divided into two categories: recoverable and terminal.

Recoverable POST Errors

When a recoverable type of error occurs during POST, the BIOS will display
an POST code that describes the problem. BIOS may also issue one of the
following beep codes:

1 long and two short beeps - video configuration error
1 continuous long beep - no memory detected

Terminal POST Errors

If a terminal type of error occurs, BIOS will shut down the system. Before
doing so, BIOS will write the error to port 80h, attempt to initialize video and
write the error in the top left corner of the screen.
The following is a list of codes that may be written to port 80h.

If the BIOS detects error 2C, 2E, or 30 (base 512K RAM error), it displays an additional
word-bitmap (xxxx) indicating the address line or bits that failed. For example, “2C
0002” means address line 1 (bit one set) has failed. “2E 1020" means data bits 12
and 5 (bits 12 and 5 set) have failed in the lower 16 bits. The BIOS also sends the
bitmap to the port-80 LED display. It first displays the checkpoint code, followed by
a delay, the high-order byte, another delay, and then the loworder byte of the error.
It repeats this sequence continuously.
