Chapter 2

Server Installation

2-1 Overview

This chapter provides a quick setup checklist to get your SuperServer 6025B-TR+/
6025B-8R+ 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 specifi c components.

2-2 Unpacking the System

You should inspect the box the SuperServer 6025B-TR+/6025B-8R+ was shipped
in and note if it was damaged in any way. If the server itself shows damage you
should fi le a damage claim with the carrier who delivered it.

Decide on a suitable location for the rack unit that will hold the SuperServer
6025B-TR+/6025B-8R+. It should be situated in a clean, dust-free area that is well
ventilated. Avoid areas where heat, electrical noise and electromagnetic fi elds are
generated. You will also need it placed near a grounded power outlet. Read the
Rack and Server Precautions in the next section.

2-3 Preparing for Setup

The box the SuperServer 6025B-TR+/6025B-8R+ was shipped in should include
two sets of rail assemblies, two rail mounting brackets and the mounting screws
you will need to install the system into the rack. 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.

2-1

SUPERSERVER 6025B-TR+/6025B-8R+ User's Manual

!

!

Choosing a Setup Location

- Leave enough clearance in front of the rack to enable you to open the front
door completely (~25 inches).

- Leave approximately 30 inches of clearance in the back of the rack to allow
for suffi cient airfl ow and ease in servicing.

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

- This product is not suitable for use with visual display work place devices ac­cording to §2 of the the German Ordinance for Work with Visual Display Units.

Warnings and Precautions!

Rack Precautions

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

fl oor 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 simul-

taneously 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 fi rst, 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 SATA/SCSI drives and power supply units to cool before touch-

ing them.

-

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

closed when not servicing to maintain proper cooling.

Chapter 2: Server Installation

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 Airfl ow

Equipment should be mounted into a rack so that the amount of airfl ow 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 SuperServer 6025B-TR+/6025B­8R+ into a rack unit. If the 6025B-TR+/6025B-8R+ has already been mounted into
a rack, 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 system into a rack with the rack rails
provided. You should also refer to the installation instructions that came with the

rack unit you are using.

Identifying the Sections of the Rack Rails

You should have received a total of six rack rail sections with the SuperServer
6025B-TR+/6025B-8R+. Two of these sections secure directly to the 6025B-TR+/
6025B-8R+ and the third (which actually consists of two joined sections) secures
directly to the rack itself. All screws and hardware mentioned in the installation
steps should be included in the hardware kit.

Refer to Figure 2-1 to determine which rail section gets attached to the front of the
chassis and which gets attached to the rear of the chassis. (The longer of the two
is the front section. The third rail section attaches to the rack.)

Installing the Chassis Rails

Position the front and rear chassis rail sections along the side of the 6025B­TR+/6025B-8R+ making sure the screw holes line up. Note that these two rails
are left/right specifi c. Screw the front chassis rail (the long piece) securely to the
side of the chassis (see Figure 2-1, step 1). There should be two screws for each
side. Repeat this procedure for the other rail on the opposite side of the chassis.
Then attach the two rear chassis rails to the chassis in the same manner, again
keeping in mind that the rails are left/right specifi c. (You will also need to attach
the rail brackets when installng into a telco rack.)

Locking Tabs: Both front chassis rails and the rack rails have a locking tab, which
serves two functions. The fi rst 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.

SUPERSERVER 6025B-TR+/6025B-8R+ User's Manual

Installing the Rack Rails:

Determine where you want to place the SuperServer 6025B-TR+/6025B-8R+ in
the rack. (See Rack and Server Precautions in Section 2-3.) Position the fi xed
rack rail/sliding rail guide assemblies (made up of two inter-locking sections) at the
desired location in the rack, keeping the sliding rail guide facing the inside of the
rack and the rollers toward the front of the rack. Screw the assembly securely to
the rack. 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.

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. Do this by lining 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). See Figure 2-2.

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.

Installing the Server into a Telco Rack

To install the SuperServer 6025B-TR+/6025B-8R+ into a Telco type rack, use two
L-shaped brackets on either side of the chassis (four total). First, determine how
far the server will extend out the front of the rack. Larger chassis should be posi­tioned to balance the weight between front and back. If a bezel is included on your
server, remove it. Then attach the two front brackets to each side of the chassis,
then the two rear brackets positioned with just enough space to accommodate the
width of the rack. Finish by sliding the chassis into the rack and tightening the
brackets to the rack.

2-5 Checking the Serverboard Setup

After you install the 6025B-TR+/6025B-8R+ in the rack, 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 2-3)

First, grasp the two handles on either side and pull the unit straight out until it locks
(you will hear a "click"). Next, depress the two buttons on the top of the chassis to
release the top cover. You can then lift the top cover from the chassis to gain full
access to the inside of the server.

2. Check the CPUs (processors)

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

3. Check the system memory

Your 6025B-TR+/6025B-8R+ server system 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.

4. 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.

5. Check all cable connections and airfl ow

Make sure all power and data cables are properly connected and not blocking the
chassis airfl ow. Also make sure that no cables are positioned in front of the fans.
See Chapter 5 for details on cable connections.

2-6 Checking the Drive Bay Setup

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

1. Accessing the drive bays

All drives are accessable from the front of the server. For servicing the DVD-ROM
and fl oppy drives, you will need to remove the top chassis cover. The Serial ATA
disk drives can be installed and removed from the front of the chassis without
removing the top chassis cover.

2. DVD-ROM and fl oppy disk drives

A slim DVD-ROM and a fl oppy drive should be preinstalled in your server. Refer
to Chapter 6 if you need to reinstall a DVD-ROM and/or fl oppy disk drive to the
system.

3. Check the SATA/SCSI drives

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

4. Check the airfl ow

Airfl ow is provided by four 8-cm center chassis cooling fans. An air shroud is also
included in the system to maximize airfl ow. The system component layout was
carefully designed to direct suffi cient cooling airfl ow to the components that gener-
ate the most heat. Note that all power and data cables have been routed in such
a way that they do not block the airfl ow generated by the fans.

5. Supplying power to the system

The last thing you must do is to provide input power to the system. Plug the power
cord(s) from the power supply unit(s) 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).

3-1 Overview

There are several LEDs on the control panel as well as others on the Serial ATA
drive carriers to keep you constantly informed of the overall status of the system as
well as the activity and health of specifi c components. There are also two buttons
on the chassis control panel.

3-2 Control Panel Buttons

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

 RESET:

 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.

3-3 Control Panel LEDs

The control panel located on the front of the chassis has several LEDs. These
LEDs 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.

 Power Fail: Indicates a power supply module has failed. The second 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.

 Overheat/Fan Fail: When this LED fl ashes, it indicates a fan failure. When
on continuously it indicates an overheat condition, which may be caused by cables
obstructing the airfl ow 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 fl ashing or on as long as the indicated condition exists.

System Safety

4-1 Electrical Safety Precautions

Basic electrical safety precautions should be followed to protect yourself from
harm and the SuperServer 6025B-TR+/6025B-8R+ from damage:

 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.

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

 Power should always be disconnected from the system when removing or

installing main system components, such as the serverboard, memory
modules and the DVD-ROM and fl oppy drives. When disconnecting power,
you should fi rst power down the system with the operating system and then
unplug the power cords of all the power supply units in the system.

 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.

 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.

 Do not use mats designed to decrease electrostatic discharge as protection

from electrical shock. Instead, use rubber mats that have been specifi cally
designed as electrical insulators.

4-1

SUPERSERVER 6025B-TR+/6025B-8R+ User's Manual

 The power supply power cord must include a grounding plug and must be

plugged into grounded electrical outlets.

 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.

 DVD-ROM Laser: CAUTION - this server may have come equipped with

a DVD-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.

 Mainboard replaceable soldered-in fuses: Self-resetting PTC (Positive Tempera-

ture Coeffi cient) fuses on the mainboard must be replaced by trained service
technicians only. The new fuse must be the same or equivalent as the one
replaced. Contact technical support for details and support.

4-2 General Safety Precautions

Follow these rules to ensure general safety:

 Keep the area around the SuperServer 6025B-TR+/6025B-8R+ clean and free

of clutter.

 The SuperServer 6025B-TR+/6025B-8R+ weighs approximately 57 lbs (25.9

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 (if
installed) to lift the chassis; the handles should only be used to pull the
server out of the rack.

 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.

 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

4-2

Chapter 4: System Safety

or be pulled into a cooling fan.

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

 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.

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 com ponents and printed
circuit boards. The following measures are generally suffi cient to neutralize this
difference before contact is made to protect your equipment from ESD:

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

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

bags until ready for use.

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

 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.

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

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

 Put the serverboard 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.

4-4 Operating Precautions

Care must be taken to assure that the chassis cover is in place when the
6025B-TR+/6025B-8R+ is operating to assure proper cooling. Out of warranty
damage to the 6025B-TR+/6025B-8R+ system can occur if this practice is not
strictly followed.

5-2 Processor and Heatsink Installation

When handling the processor, avoid placing direct pressure on the label
area of the fan. Also, do not place the serverboard on a conductive
surface, which can damage the BIOS batter y and prevent the system
from booting up.

IMPORTANT: Always c onne ct t he p ower c or d last a nd re move it fi rst before add-
ing, removing or changing any hardware components. Make sure that you install
the pro cessor i nto the CPU soc ket before you install the he atsink and fan. T he
X7DBE+/X7DB 8+ can suppor t either one or t wo Xeon LGA 771 processors. If
instal ling one p roc esso r only, instal l it into CPU s ocket #1.

Notes:

1. Intel's boxed Xeon CPU package contains a CPU fan and heatsink assembly. If
you buy a CPU separately, make sure that you use only Intel-certifi ed multi-direc-
tional heatsinks and fans.

2. When purchasing an LGA 771 CPU or when receiving a serverboard with an LGA
771 CPU pre-installed, make sure that the CPU plastic cap is in place and none of
the CPU pins are bent; otherwise, contact the retailer immediately.

3. Revision 2.0 and above of the X7DBE+/X 7DB8+ will also support "Woodcrest"
CPUs.

4. Align pin1 of the CPU (the cor-

ner marked with a triangle) with the
notched corner of the CPU socket.

5. Find the corner of the CPU that

has a semi-circle cutout below a gold
dot (CPU key). This corner should be
aligned with the cutout on the socket
(socket key).

6. Once aligned, carefully lower the

CPU straight down into the socket.
Do not drop the CPU on the socket,
do not move the CPU horizontally
or vertically and do not rub the CPU
against any surface or any of the
contacts, which may damage the CPU
and/or contacts.

5- 6 Adding PCI Card s

1. PCI slots

The X7DBE+/X7DB8+ has six PCI expansion slots, which includes two x8 PCI­Express slots, one x4 PCI-Express slot, two 64-bit 133 MHz PCI-X slots and one
64-bit 100 MHz PCI-X slot. On the X7DB8+, the 100 MHz PCI-X slot supports Zero
Channel RAID (ZCR).

2. PCI card installat ion
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, above). After gaining access to the inside of the
server, determine which slot you wish to populate, then press down on the curved
section at the top of the blue tab for that slot. While pressing down, lift the tab to
unlock the shield. Insert the expansion card into the correct slot on the serverboard,
pushing down with your thumbs evenly on both sides of the card. Lock the card
into place by pressing down on the tab. 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
conne cto r. Pin 1 is identifi ed with
a square solder pad on the printed
circu it boar d. See the d iagra m at
right for an example of jumping pins
1 and 2. Refer to the serve rboard
layout page for jumper locations.

Note: On two-pin jumpers, "Cl osed"
means the jumper is on and "Open"

means th e jumper i s off t he pins .

Advanced Chassis Setup

This chapter covers the steps required to install components and perform mainte­nance on the SC825TQ-R700LP/SC825S2-R700LP chassis. For component instal­lation, follow the steps in the order given to eliminate the most common problems
encountered. If some steps are unnecessary, skip ahead to the step that follows.

Tools Required

The only tool you will need to install components and perform maintenance is a
Philips screwdriver.

6-1 Static-Sensitive Devices

Electrostatic discharge (ESD) can damage electronic com ponents. To prevent
damage to any printed circuit boards (PCBs), it is important to handle them very
carefully . The following measures are generally suffi cient to protect your equipment
from ESD damage.

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 motherboard, 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 to avoid static damage. When
unpacking the board, make sure the person handling it is static protected.

ribbon cable has bundled these wires together to simplify the connection. Connect
the cable from JF1 on the serverboard to JP4 on the Control Panel PCB (printed
circuit board). Make sure the red wire plugs into pin 1 on both JF1 and JP4. Pull
all excess cabling out of the airfl ow path. The LEDs inform you of system status.
See Chapter 3 for details on the LEDs and the control panel buttons. Details on
JF1 can be found in Chapter 5.

Chapter 6: Advanced Chassis Setup

6-3 System Fans

Three 8-cm hot-swap fans provide the cooling for the SuperServer 6025B-TR+/
6025B-8R+. It is very important that the chassis top cover is properly installed and
making a good seal in order for the cooling air to circulate properly through the
chassis and cool the components. See Figure 6-2.

System Fan Failure

Fan speed is controlled by system temperature via a BIOS setting. If a fan fails,
the remaining fans will ramp up to full speed and the overheat/fan fail LED on the
control panel will turn on. Replace any failed fan at your earliest convenience
with the same type and model (the system can continue to run with a failed fan).
Remove the top chassis cover while the system is still running to determine which
of the fans has failed.

Replacing System Fans

1. Removing a fan

Remove the chassis cover. Press the tabs on the sides of the fan to unlock and
remove the fan and its housing. The fan's power connections will automatically
detach. System power does not need to be shut down since the fans are hot-plug­gable.

2. Installing a new fan

Replace the failed fan with an identical 8-cm, 12 volt fan (available from Supermicro,
p/n FAN-0070). Position the new fan into the space vacated by the failed fan previ­ously removed. A "click" can be heard when the fan is fully installed in place and
the power connections are made. If the system power is on, the hot-plug feature
will cause the fan to start immediately upon being connected to its header on the
serverboard.

SATA/SCSI Drive Installation

1. Mounting a SATA/SCSI drive in a drive carrier

The SA TA/SCSI drives are mounted in drive carriers to simplify their installation and
removal from the chassis. These carriers also help promote proper airfl ow for the
drives. For this reason, even empty carriers without SATA/SCSI drives installed
must remain in the chassis. To add a new SATA/SCSI drive, install a drive into the
carrier with the printed circuit board side facing down so that the mounting holes
align with those in the carrier. Secure the drive to the carrier with four screws, as
shown in Figure 6-3.

Figure 6-3. Mounting a SATA/SCSI Drive in a Carrier

Use caution when working around the SATA/SCSI backplane.
Do not touch the backplane with any metal objects and make
sure no ribbon cables touch the backplane or obstruct the holes,
which aid in proper airfl ow.

Important: Regardless of how many SATA/SCSI hard drives
are installed, all drive carriers must remain in the drive bays to
maintain proper airfl ow.

2. Installing/removing hot-swap SATA/SCSI drives

The SATA/SCSI drive carriers are all easily accessible at the front of the chassis.
These hard drives are hot-pluggable, meaning they can be removed and installed
without powering down the system. To remove a carrier, push the release button
located beside the drive LEDs. Then swing the colored handle fully out and use it
to pull the unit straight out (see Figure 6-4).

Note: Your operating system must have RAID support to enable the hot-plug ca­pability of the SATA/SCSI drives.

Chapter 6: Advanced Chassis Setup

Hard Drive Backplane

The SATA/SCSI drives plug into a backplane that provides power, drive ID and
bus termination. A RAID controller can be used with the backplane to provide data
security. The operating system you use must have RAID support to enable the hot­swap capability of the Serial ATA drives. The backplane is already preconfi gured,
so there are no jumpers or switches present on it.

DVD-ROM and Floppy Drive Installation

The top cover of the chassis must be opened to gain full access to the DVD-ROM
and fl oppy drive bays. The 6025B-TR+/6025B-8R+ accomodates only slim type
DVD-ROM drives. Side mounting brakets are typically needed to mount a slim
DVD-ROM drive in the 6025B-TR+/6025B-8R+ server.

First, release the retention screws that secure the server 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"). Next, depress the two buttons on the top of the chassis to release
the top cover and at the same time, push the cover away from you until it stops.
You can then lift the top cover from the chassis to gain full access to the inside of
the server. You must power down the system before installing or removing fl oppy
or IDE components.

Drives mount on rails and should "click" into place to be correctly and fully installed
in their bays.

• The fl oppy disk drive cable has seven twisted wires.

• A color mark on a cable typically designates the location of pin 1.

• A single fl oppy disk drive ribbon cable has 34 wires and two connectors to provide
for two fl oppy 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.

SUPERSERVER 6025B-TR+/6025B-8R+ User's Manual

6-5 Power Supply

The SuperServer 6025B-TR+/6025B-8R+ has a 700 watt redundant power supply
consisting of two power modules. Each power supply module has an auto-switching
capability, which enables it to automatically sense and operate at a 100V - 240V
input voltage.

Power Supply Failure

If either of the two power supply modules fail, the other module will take the full
load and allow the system to continue operation without interruption. The PWR
Fail LED will illuminate and remain on until the failed unit has been replaced. Re­placement units can be ordered directly from Supermicro (see contact information
in the Preface). The power supply units have a hot-swap capability, meaning you
can replace the failed unit without powering down the system.

Removing/Replacing the Power Supply

You do not need to shut down the system to replace a power supply unit. The
backup power supply module will keep the system up and running while you replace
the failed hot-swap unit. Replace with the same model (see part number in the

Appendix), which can be ordered directly from Supermicro.

1. Removing the power supply
First unplug the power cord from the failed power supply module. Then depress
the locking tab on the power supply module and use the handle to pull it straight
out with the rounded handle.

2. Installing a new power supply
Replace the failed hot-swap unit with another identical power supply unit. Simply
push the new power supply unit into the power bay until you hear a click. Secure
the locking tab on the unit and fi nish by plugging the AC power cord back into the
unit.

Chapter 7: BIOS

BIOS

7-1 Introduction

This chapter describes the Phoenix BIOS™ Setup utility for the X7DBE+/X8DB8+.
The Phoenix ROM BIOS is stored in a fl ash chip and can be easily upgraded using
a fl oppy disk-based program.

Note: Due to periodic changes to the BIOS, some settings may have been added or
deleted and might not yet be recorded in this manual. Please refer to the Manual
Download area of the Supermicro web site <http://www.supermicro.com> for any
changes to the BIOS that may not be refl ected in this manual.

System BIOS

The BIOS is the Basic Input Output System used in all IBM® PC, XT™, AT®, and
PS/2® compatible computers. The Phoenix BIOS fl ash chip stores the system
parameters, types of disk drives, video displays, etc. in the CMOS. The CMOS
memory requires very little electrical power. When the computer is turned off, a
backup battery provides power to the BIOS fl ash chip, enabling it to retain system
parameters. Each time the computer is powered on the computer is confi gured
with the values stored in the BIOS ROM by the system BIOS, which gains control
at boot up.

How To Change the Confi guration Data

The CMOS information that determines the system parameters may be changed by
entering the BIOS Setup utility. This Setup utility can be accessed by pressing the
<Delete> key at the appropriate time during system boot. (See below.)

Starting the Setup Utility

Normally , the only visible POST (Power On Self Test) routine is the memory test. As
the memory is being tested, press the <Delete> key to enter the main menu of the
BIOS Setup utility. From the main menu, you can access the other setup screens,
such as the Security and Power menus. Beginning with Section 7-3, detailed de­scriptions are given for each parameter setting in the Setup utility.

Warning! To prevent possible boot failure, do not shut down or reset the system
while updating the BIOS.

Previous POST did not complete successfully. POST loads default values and offers
to run Setup. If the failure was caused by incorrect values and they are not corrected,
the next boot will likely fail. On systems with control of wait states, improper Setup
settings can also terminate POST and cause this error on the next boot. Run Setup
and verify that the waitstate confi guration is correct. This error is cleared the next
time the system is booted.

Appendix B: BIOS POST Codes

Appendix B

BIOS POST Codes

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 confi guration error

1 repetitive 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.
