Chapter 2

Server Installation

2-1 Overview

This chapter provides a quick setup checklist to get your 2021M-T2R+/2021M-82R+

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-T2R+/2021M-82R+ 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-T2R+/2021M-82R+ 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-T2R+/2021M-82R+ 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).

!

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.

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 tempera-

ture 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 tempera-

ture (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 connec-

tions 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 2021M-T2R+/2021M-82R+

into a rack unit. If the 2021M-T2R+/2021M-82R+ 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 2021M-T2R+/

2021M-82R+. Two of these sections secure directly to the 2021M-T2R+/2021M-

82R+ 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-

T2R+/2021M-82R+ 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.

AS2021M-T2R+/2021M-82R+ User's Manual

Installing the Rack Rails:

Determine where you want to place the 2021M-T2R+/2021M-82R+ in the rack.

(See Rack and Server Precautions in Section 2-3.) Position the fi xed rack rail/slid-

ing 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 chas-

sis 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

If you are installing the 2021M-T2R+/2021M-82R+ into a Telco type rack, follow

the directions given on the previous pages for rack installation. The only differ-

ence in the installation procedure will be the positioning of the rack brackets to the

rack. They should be spaced apart just enough to accommodate the width of the

telco rack.

2-5 Checking the Serverboard Setup

After you install the 2021M-T2R+/2021M-82R+ 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-T2R+/2021M-82R+ 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

and SCSI 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 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 units into a high-quality power strip that offers protec-

tion from electrical noise and power surges. It is recommended that you use an

uninterruptible power supply (UPS).

AS2021M-T2R+/2021M-82R+ 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.

4-1 Electrical Safety Precautions

!

Basic electrical safety precautions should be followed to protect yourself from

harm and the 2021M-T2R+/2021M-82R+ 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-T2R+/2021M-82R+ 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-T2R+/2021M-82R+ clean and free of

clutter.

 The 2021M-T2R+/2021M-82R+ 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.

Advanced Serverboard Setup

This chapter covers the steps required to install processors and heatsinks to the

H8DME-2/H8DM8-2 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 fi nished working on the serverboard to

protect and cool the system suffi ciently.

5-1 Handling the Serverboard

Static electrical discharge can damage electronic com ponents. To prevent dam-

age 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 sup-

port it when handling. The following measures are generally suffi cient 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.

5-2 Processor and Heatsink Installation

Exercise extreme caution when handling and installing the proces-

!

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.

sor. Always connect the power cord last and always remove it be-

fore adding, removing or changing any hardware components.

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 in-

stalled 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 reten-

tion 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-T2R+/2021M-82R+ 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 clip-

and-cam type heatsinks from third parties.

Figure 2-1. CPU Heatsink Retention Module Installation

Installing the Heatsink

The use of active type heatsinks (except for 1U systems) are recommended. Con-

nect the heatsink fans to the appropriate fan headers on the serverboard. To install

the heatsinks, please follow the installation instructions included with your heatsink

package (not included).

Chapter 5: Advanced Serverboard Setup

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 preconfi gured systems to prevent them from blocking the fl ow

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 reroute them as they

were originally after reconnecting them (make sure the red wires connect to the

pin 1 locations). If you are confi guring the system, keep the airfl ow in mind when

routing the cables. The following data cables (with their serverboard connector

locations noted) should be connected. See the serverboard layout diagram in this

chapter for connector locations.

 DVD-ROM drive cable (IDE#1)

 2021M-T2R+: SATA cables (SATA0 ~ SATA5)

 2021M-T2R+: SATA Enclosure Management LED cable (SGPIO1)

 2021M-82R+: SCSI cables (JA1, JA2)

 Control Panel cable (JF1, see next page)

Connecting Power Cables

The H8DME-2/H8DM8-2 has a 24-pin primary power supply connector designated

"JPW1" for connection to the ATX power supply. Connect the appropriate con-

nector from the power supply to the "ATX Power" connector to supply power to

the serverboard. See the Connector Defi nitions section in this chapter for power

connector pin defi nitions.

In addition, your power supply must be connected to the 4-pin Secondary ATX

Power connection at J32 and the 8-pin processor power connector at JPW2.

AS2021M-T2R+/2021M-82R+ User's Manual

Connecting the Control Panel

JF1 contains header pins for various front control panel connectors. See Figure

5-3 for the pin locations of the various front control panel buttons and LED indi-

cators. Please note that even and odd numbered pins are on opposite sides of

each header.

All JF1 wires have been bundled into single keyed ribbon cable to simplify their

connection. The red wire in the ribbon cable plugs into pin 1 of JF1. Connect

the other end of the cable to the Control Panel printed circuit board, located just

behind the system status LEDs in the chassis.

See the Connector Defi nitions section in this chapter for details and pin descrip-

tions of JF1.

5-5 Installing Memory

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

CAUTION!

Exercise extreme care when installing or removing DIMM modules

to prevent any possible damage. Also note that the memory 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. 128 MB, 256 MB, 512 MB,

1 GB and 2 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-T2R+/2021M-82R+ User's Manual

Support

The H8DM8-2/H8DME-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: 32 GB of registered ECC DDR2-667/533 or 64 GB of regis-

tered ECC DDR2-400. If only one CPU is installed, maximum supported memory

is halved.

Express x8 slots, two 64-bit 133 MHz PCI-X slots and two 64-bit 100 MHz PCI-X

slots. On the H8DM8-2, one 100 MHz PCI-X slot supports Zero Channel RAID

(ZCR). The 2021M-T2R+/2021M-82R+ can support low-profi le cards in all six slots

of the serverboard.

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, 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

connector. Pin 1 is identifi ed with

a square solder pad on the printed

circuit board. See the diagram at

right for an example of jumping pins

1 and 2. Refer to the serverboard

layout page 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

Connector

321

Pins

Jumper

321

Setting

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.

Use the following information to connect the fl oppy and hard disk drive cables.

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

 A red mark on a wire 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.

 The 80-wire ATA133 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.

5-12 Enabling SATA RAID

Now that the hardware is set up, you must now install the operating system and the

SATA RAID drivers, if you wish to use RAID with your SATA drives. The installation

procedure differs depending on whether you wish to have the operating system

installed on a RAID array or on a separate non-RAID drive. See the instructions

below for details.

Serial ATA (SATA)

Serial ATA (SATA) is a physical storage interface that employs a single cable with a

minimum of four wires to create a point-to-point connection between devices. This

connection is a serial link that supports a SATA transfer rate from 150 MBps. The

serial cables used in SATA are thinner than the traditional cables used in Parallel

ATA (PATA) and can extend up to one meter in length, compared to only 40 cm for

PATA cables. Overall, SATA provides better functionality than PATA.

Installing the OS/SATA Driver

Before installing the OS (operating system) and SATA RAID driver, you must decide

if you wish to have the operating system installed as part of a bootable RAID array

or installed to a separate non-RAID hard drive. If on a separate drive, you may

install the driver either during or after the OS installation. If you wish to have the

OS on a SATA RAID array, you must follow the procedure below and install the

driver during the OS installation.

Building a Driver Diskette

You must fi rst build a driver diskette from the Supermicro CD-ROM that was included

with the system. (You will have to create this disk on a computer that is already

running and with the OS installed.) Insert the CD into your CD-ROM drive and

start the system. A display as shown in Figure 2-5 will appear. Click on the icon

labeled "Build Driver Diskettes and Manuals" and follow the instructions to create

a fl oppy disk with the driver on it. Once it's been created, remove the fl oppy and

insert the installation CD for the Windows Operating System you wish to install into

the CD-ROM drive of the new system you are about to confi gure.

Enabling SATA RAID in the BIOS

Before installing the Windows Operating System, you must change some settings

in BIOS. Boot up the system and hit the <Del> key to enter the BIOS Setup Utlility.

After the Setup Utility loads,

1. Use the arrow keys to move to the Exit menu. Scroll down with the arrow keys

to the "Load Optimal Defaults setting and press <Enter>. Select "OK" to confi rm,

then <Enter> to load the default settings.

5-28

Chapter 5: Advanced Serverboard Setup

2. Use the arrow keys to move to Advanced > Floppy/IDE/SATA Confi guration >

nVidia RAID Setup and press the <Enter> key. Once in the submenu, enable the

"nVidia RAID Function" setting, which will cause the SATA0/1/2 Primary/Secondary

settings to appear. Enable the SATA devices and channels you will be using.

3. Hit the <Esc> key twice and scroll to the Exit menu. Select "Save Changes and

Exit" and hit <enter>, then hit <Enter> again to verify.

4. After exiting the BIOS Setup Utility, the system will reboot. When prompted

during the startup, press the <F10> key when prompted to run the nVidia RAID

Utility program.

Using the nVidia RAID Utility

The nVidia RAID Utility program is where you can defi ne the drives you want to

include in the RAID array and the mode and type of RAID. Two main windows

are shown in the utility. The "Free Disks" window on the left will list all available

drives. Use the arrow keys to select and move drives to the window on the right,

which lists all drives that are to become part of the RAID array.

Once you have fi nished selecting the drives and type of RAID you wish to use for

your RAID array, press the <F7> key. You will be prompted to verify your choice; if

you want to continue with your choices, select "Yes". Note that selecting "Yes" will

clear all previous data from the drives you selected to be a part of the array. You

are then given the choice of making the RAID array bootable by pressing the the

<B> key. After you have fi nshed, press the <Ctrl> and <X> keys simultaneously.

Installing the OS and Drivers

With the Windows OS installation CD in the CD-ROM drive, restart the system.

When you see the prompt, hit the <F6> key to enter Windows setup. Eventually a

blue screen will appear with a message that begins "Windows could not determine

the type of one or more storage devices . . ." When you see the screen, hit the <S>

key to "Specify Additional Device", then insert the driver diskette you just created

into the fl oppy drive. Highlight "Manufuacturer Supplied Hardware Support Disk"

and hit the <Enter> key. Highlight the fi rst "nVidia RAID" driver shown and press

the <Enter> key to install it. Soon a similar blue screen will appear again. Again hit

the <S> key, then highlight the second item, "nForce Storage Controller" and press

the <Enter> key, then <Enter> again to continue with the Windows setup.

Advanced Chassis Setup

This chapter covers the steps required to install components and perform mainte-

nance on the SC825TQ-R700LP/SC825S2-R700LP chassis. For component instal-

lation, 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.

Chapter 6: Advanced Chassis Setup

6-3 System Fans

Three 8-cm hot-swap fans provide the cooling for the 2021M-T2R+/2021M-82R+.

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-plug-

gable.

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 previ-

ously 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 SATA/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.

AS2021M-T2R+/2021M-82R+ User's Manual

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 ca-

pability 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 hot-

swap 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 2021M-T2R+/2021M-82R+ accomodates only slim type

DVD-ROM drives. Side mounting brakets are typically needed to mount a slim

DVD-ROM drive in the 2021M-T2R+/2021M-82R+ 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-T2R+/2021M-82R+ User's Manual

6-5 Power Supply

The 2021M-T2R+/2021M-82R+ has a 700 watt redundant power supply consisting

of two power modules. Each power supply module has an auto-switching capabil-

ity, 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. Replace-

ment 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.

7-1 Introduction

This chapter describes the AMIBIOS™ Setup utility for the H8DM8-2/H8DME-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 mes-

sage. 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.) Set-

tings 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.

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 pro-

cedure. 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.
