Chapter 2

Server Installation

2-1 Overview

This chapter provides a quick setup checklist to get your 2021M-32R 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 2021M-32R 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 server. 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 2021M-32R 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

AS2021M-32R 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 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 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 SAS 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.

2-2

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.).

AS2021M-32R User's Manual

2-4 Installing the System into a Rack

This section provides information on installing the 2021M-32R into a rack unit. If the
2021M-32R 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 instal-

lation 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 2021M-32R. Two
of these sections secure directly to the 2021M-32R 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 2021M-32R
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.

2-4

Chapter 2: Server Installation

Figure 2-1. Installing Chassis Rails

2-5

AS2021M-32R User's Manual

Installing the Rack Rails:

Determine where you want to place the 2021M-32R in the rack. (See Rack and
Server Precautions in Section 2-3.) Position the fi xed rack rail/sliding rail guide as-
semblies (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 2021M-32R into a Telco type rack, use two L-shaped brackets on
either side of the chassis (four total). First, determine how far follow 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
telco 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 2021M-32R 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 2021M-32R 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 SAS 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 SAS 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 SAS drives
Depending upon your system's confi guration, your system may have one or more
drives already installed. If you need to install SAS drives, please refer to Chapter

6.

4. Check the airfl ow
Airfl ow is provided by three 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
generate 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
cords from the power supply modules 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 SAS 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 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.

Use the reset button to reboot the system.

AS2021M-32R User's Manual

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 2021M-32R 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

AS2021M-32R 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.

4-2 General Safety Precautions

Follow these rules to ensure general safety:

 Keep the area around the 2021M-32R clean and free of clutter.

 The 2021M-32R 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
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.

4-2

Chapter 4: System Safety

!

 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.

5-2 Processor and Heatsink Installation

Exercise extreme caution when handling and installing the proces­sor. Always connect the power cord last and always remove it be­fore adding, removing or changing any hardware components.

Installing the CPU Backplates

Two CPU backplates (BKT-0011L) have been preinstalled to the serverboard to
prevent the CPU area of the serverboard from bending and to provide a base for
attaching the heatsink retention modules.

Installing the Processor (install to the CPU#1 socket fi rst)

1. Begin by removing the cover plate
that protects the CPU. Lift the lever
on CPU socket #1 until it points straight
up. With the lever raised, lift open the
silver CPU retention plate.

Triangles

2. Use your thumb and your index
fi nger to hold the CPU. Locate and
align pin 1 of the CPU socket with pin
1 of the CPU. Both are marked with
a triangle.

5-2

3. Align pin 1 of the CPU with pin 1

of the socket. Once aligned, carefully
place the CPU into the socket. Do not

drop the CPU on the socket, move the
CPU horizontally or vertically or rub the
CPU against the socket or against any
pins of the socket, which may damage
the CPU and/or the socket.

Chapter 5: Advanced Serverboard Setup

4. With the CPU inserted into the

socket, inspect the four corners of the
CPU to make sure that it is properly in­stalled and fl ush with the socket. Then,
gently lower the silver CPU retention
plate into place.

5. Carefully press the CPU socket

lever down until it locks into its reten­tion tab. For a dual-processor system,
repeat these steps to install another
CPU into the CPU#2 socket.
Note: if using a single processor, only
the CPU1 DIMM slots are addressable
for a maximum of 16 GB memory.

AS2021M-32R User's Manual

Installing the Heatsink Retention Modules

Two heatsink retention modules (BKT-0012L) and four screws are included in the
retail box. Once installed, these are used to help attach the heatsinks to the CPUs.
To install, align the module with the standoffs of the preinstalled CPU backplate and
with the four feet on the module contacting the serverboard. Secure the retention
module to the backplate with two of the screws provided. See Figure 2-1. Repeat
for the second CPU socket.

Note: BKT-0012L is included for use with non-proprietary heatsinks only. When
installing proprietary heatsinks, only BKT-0011L (the CPU backplate) is needed.
The BKT-0012L retention module was designed to provide compatibility with clip­and-cam type heatsinks from third parties.

5-5 Installing Memory

Note: Check the Sup ermi cro web s ite for rec omme nded me mor y modul es.

CAUTION!

Exercise extreme care when installing or removing DIMM modules

to prevent any pos sible da mage. Al so note th at the mem or y is inter-

leaved to improve performance (see step 1).

1. Insert each memory module vertically into its slot, paying attention to the notch

along the bottom of the module to prevent inserting the module incorrectly (see
Figure 5-5). See support information below.

2. Gently press down on the memory module until it snaps into place.

Note: each processor has its own built-in memory controller, so the CPU2 DIMMs
cannot be addressed if only a single CPU is installed. 256 MB, 512 MB, 1 GB, 2
GB and 4 GB memory modules are supported. It is highly recommended that you
remove the power cord from the system before installing or changing DIMMs.

5-7

AS2021M-32R User's Manual

Support

The H8DM3-2 supports single or dual-channel, DDR2-667/533/400 registered ECC
SDRAM.
Both interleaved and non-interleaved memory are supported, so you may populate
any number of DIMM slots (see note on previous page and charts on following
page). The CPU2 DIMM slots can only be accessed when two CPUs are installed
(however, the CPU2 DIMM slots are not required to be populated when two CPUs
are installed).
Populating two adjacent slots at a time with memory modules of the same size and
type will result in interleaved (128-bit) memory, which is faster than non-interleaved
(64-bit) memory. See charts on following page.

Optimizing memory performance

If two processors are installed, it is better to stagger pairs of DIMMs across both
sets of CPU DIMM slots, e.g. fi rst populate CPU1 slots 1A and 1B, then CPU2 slots
1A, and 1B, then the next two CPU1 slots, etc. This balances the load over both
CPUs to optimize performance.

Maximum memory: 64 GB of DDR2-667 or 32 GB of DDR2-533/400 registered
ECC SDRAM. If only one CPU is installed, maximum supported memory is
halved.

5-9 Jumper Settings

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 ser ve 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 .

CMOS Clear

JBT1 is used to clear CMOS and will also clear any passwords. Instead of pins,
this jumper consists of contact pads to prevent accidentally clearing the contents
of CMOS.
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 for at least four seconds.

3) Remove the screwdriver (or shorting device).

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

Notes:

Do not use the PW_ON connector to clear CMOS.

The onboard battery does not need to be removed when clearing CMOS, however
you must short JBT1 for at least four seconds.

Advanced Chassis Setup

This chapter covers the steps required to install components and perform mainte­nance on the SC825TQ-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 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 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 2021M-32R. 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-0094L). 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.

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.

Chapter 6: Advanced Chassis Setup

!

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. To reinstall, simply position the air shroud in its
proper place and push it in until you hear it click.

SAS Drive Installation

1. Mounting a SAS drive in a drive carrier

The SAS 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 SAS drives installed must
remain in the chassis. To add a new SAS 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 SAS Drive in a Carrier

Use caution when working around the SAS 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 SAS hard drives are
installed, all drive carriers must remain in the drive bays to
maintain proper airfl ow.

2. Installing/removing hot-swap SAS drives

The SAS 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 SAS drives.

Important: All of the SAS drive carriers must remain in the drive
bays to maintain proper cooling airfl ow.

Chapter 6: Advanced Chassis Setup

Hard Drive Backplane

The SAS 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 hot-swap
capability of the SAS 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 2021M-32R accomodates only slim type DVD-ROM
drives. Side mounting brakets are typically needed to mount a slim DVD-ROM
drive in the 2021M-32R 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.

AS2021M-32R User's Manual

6-5 Power Supply

The 2021M-32R 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 modules have a hot-swap capability, meaning you can
replace the failed module without powering down the system.

Removing/Replacing the Power Supply

You do not need to shut down the system to replace a power supply module. The
backup power supply module will keep the system up and running while you replace
the failed hot-swap module. 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 module with another identical power supply. Simply
push the new power supply module 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
module.

BIOS

7-1 Introduction

This chapter describes the AMIBIOS™ Setup utility for the H8DM3-2. The AMI
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 our web site for any changes to BIOS that may not be refl ected
in this manual.

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>, etc.) 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 confi gured. “Grayed-out” options cannot be confi gured. 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 that BIOS has default text messages built in.
We retain the option to include, omit, or change any of these text messages.) Set­tings printed in Bold are the default values.
A "

" indicates a submenu. Highlighting such an item and pressing the <Enter>

key will open the list of settings within that submenu.

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.

7-2 Main Menu

When you fi rst enter AMI BIOS Setup Utility, you will see the Main Menu screen.
You can always return to the Main Menu by selecting the Main tab on the top of
the screen with the arrow keys.

The Main Menu screen provides you with a system overview, which includes the
version, built date and ID of the AMIBIOS, the type, speed and number of the
processors in the system and the amount of memory installed in the system.

System Time/System Date

You can edit this fi eld to change the system time and date. Highlight System Time
or System Date using the <Arrow> keys. Enter new values through the keyboard.
Press the <Tab> key or the <Arrow> keys to move between fi elds. The date must
be entered in DAY/MM/DD/YYYY format. The time is entered in HH:MM:SS format.
Please note that time is in a 24-hour format. For example, 5:30 A.M. appears as
05:30:00 and 5:30 P.M. as 17:30:00.

Appendix A

BIOS Error Beep Codes

During the POST (Power-On Self-Test) routines, which are performed each time
the system is powered on, errors may occur.

Non-fatal errors are those which, in most cases, allow the system to continue the
boot-up process. The error messages normally appear on the screen.

Fatal errors are those which will not allow the system to continue the boot-up pro­cedure. If a fatal error occurs, you should consult with your system manufacturer
for possible repairs.

These fatal errors are usually communicated through a series of audible beeps.
The numbers on the fatal error list, on the following page, correspond to the number
of beeps for the corresponding error. All errors listed, with the exception of Beep
Code 8, are fatal errors.

POST codes may be read on the debug LEDs located beside the LAN port on the
serverboard backplane. See the description of the Debug LEDs (LED1 and LED2)
in Chapter 5.

BIOS POST Checkpoint Codes

When AMIBIOS performs the Power On Self Test, it writes checkpoint codes to I/O
port 0080h. If the computer cannot complete the boot process, diagnostic equipment
can be attached to the computer to read I/O port 0080h.
