Server Installation

2-1 Overview

This chapter provides a quick setup checklist to get your 4021M-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.

The 4021M-32R may be employed either as a tower or mounted in a rack as a 4U

rackmount chassis. If using it as a tower unit, please read the Server Precautions

in the next section and then skip ahead to Section 2-5.

2-2 Unpacking the System

You should inspect the box the system was shipped in and note if it was damaged

in any way. If the server itself shows damage you should fi le a damage claim with

the carrier who delivered it.

Decide on a suitable location for the 4021M-32R. 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. Be sure to read the Rack and Server Precautions in the next sec-

tion.

2-3 Preparing for Setup

The box the system was shipped in may include two sets of rail assemblies, two

rail mounting brackets and mounting screws needed for installing the system into a

rack (optional kit). Follow the steps in the order given to complete the installation

process in a minimum amount of time. Please read this section in its entirety before

you begin the installation procedure outlined in the sections that follow.

2-1

AS4021M-32R User's Manual

Choosing a Setup Location

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

door completely (~25 inches).

- Leave approximately 30 inches of clearance in the back of the system to allow for

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.

! !

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.

Warnings and Precautions!

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 touching

them.

-

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

closed when not servicing to maintain proper cooling.

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.).

2-3

AS4021M-32R User's Manual

2-4 Installing the System into a Rack

This section provides information on installing the system into a rack unit. Rack

installation requires the use of the optional rackmount kit. If the system has already

been mounted into a rack or if you are using it as a tower, you can skip ahead to

Sections 2-5 and 2-6. There are a variety of rack units on the market, which may

mean the assembly procedure will differ slightly. The following is a guideline for

installing the server into a rack with the rack rails provided in the rackmount kit.

You should also refer to the installation instructions that came with the rack unit

you are using.

Identifying the Sections of the Rack Rails

The optional rackmount kit includes two rack rail assemblies. Each of these as-

semblies consist of three sections: an inner fi xed chassis rail that secures to the

chassis, an outer rack rail that secures directly to the rack itself and two rail brackets,

which also attack to the rack (see Figure 2-1.) The inner and outer rails must be

detached from each other to install.

To remove the inner chassis rail, pull it out as far as possible - you should hear a

"click" sound as a locking tab emerges from inside the rail assembly and locks the

inner rail. Depress the locking tab to pull the inner rail completely out. Do this for

both assemblies (one for each side).

2-4

Chapter 2: Server Installation

Installing the Chassis Rails

You will need to remove the top cover and the feet to add rack rails to the chassis.

First, remove the top and right covers (top and left covers when standing as a tower

chassis) by fi rst removing the screws that secure them to the chassis. Depress

the button on the top (side if tower) of the chassis to release the cover and then

pull the cover off. Then unscrew the four feet and remove them from the chassis

(see Figure 2-2).

You can now attach rack rails to the top and bottom (now the sides) of the chassis.

First add the rack handles. Then position the inner chassis rail sections you just

removed along the side of the chassis making sure the screw holes line up. Note

that these two rails are left/right specifi c. Screw the rail securely to the side of the

chassis (see Figure 2-3). Repeat this procedure for the other rail on the other side

of the chassis. You will also need to attach the rail brackets when installing into a

telco rack.

Locking Tabs: As mentioned, the chassis rails have a locking tab, which serves

two functions. The 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.

Figure 2-2. Preparing to Install the Chassis Rails

Figure 2-3. Installing the Rails to the Chassis

Installing the Rack Rails

Determine where you want to place the SuperServer 4021M-32R in the rack. (See

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

guide assemblies at the desired location in the rack, keeping the sliding rail guide

facing the inside of the rack. Screw the assembly securely to the rack using the

brackets provided. Attach the other assembly to the other side of the rack, making

sure both are at the exact same height and with the rail guides facing inward.

2-6

Chapter 2: Server Installation

Installing the Server into the Rack

You should now have rails attached to both the chassis and the rack unit. The next

step is to install the server into the rack. You should have two brackets in the rack

mount kit. Install these fi rst keeping in mind that they are left/right specifi c (marked

with "L" and "R"). Then, line up the rear of the chassis rails with the front of the

rack rails. Slide the chassis rails into the rack rails, keeping the pressure even on

both sides (you may have to depress the locking tabs when inserting).

When the server has been pushed completely into the rack, you should hear the

locking tabs "click". Finish by inserting and tightening the thumbscrews that hold

the front of the server to the rack (see Figure 2-4).

2-5 Checking the Serverboard Setup

After setting up the the system, you will need to open the unit to make sure the

serverboard is properly installed and all the connections have been made.

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

[If rack mounted, fi rst release the retention screws that secure the unit to the

rack. Grasp the two handles on either side and pull the unit straight out until it

locks (you will hear a "click").] There are two screws that secure the cover to

the chassis - remove these fi rst. Locate the latch on the top (side if tower) of

the chassis - depress where it says "push" then lift the latch to release the cover.

You can then lift the cover from the chassis to gain full access to the inside of

the server.

2. Check the CPUs (processors)

You may have one or two processors already installed into the serverboard. Each

processor should have its own heatsink attached. See Chapter 5 for instructions

on processor installation.

3. CPU clock ratio setting

The CPU speed should be automatically detected. No jumper or BIOS settings

need to be made.

4. Check the system memory

Your server may have come with system memory already installed. Make sure

all DIMMs are fully seated in their slots. For details on adding system memory,

refer to Chapter 5.

5. Installing add-on cards

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

on installing PCI add-on cards.

6. Check all cable connections and airfl ow

Make sure all power and data cables are properly connected and not blocking

the chassis airfl ow. See Chapter 5 for details on cable connections.

Chapter 2: Server Installation

Figure 2-5. Accessing the Inside of the System

(Rack Confi guration shown)

2-6 Checking the Drive Bay Setup

Next, you should check to make sure the peripheral drives and the SAS drives and

backplane have been properly installed and all connections have been made.

1. Accessing the drive bays

All drives can be accessed from the front of the server. For servicing the CD-

ROM, IDE hard drives and fl oppy drives, you will need to remove the top/left

chassis cover. The SAS disk drives can be installed and removed from the front

of the chassis without removing any chassis covers.

2. Installing components into the 5.25" drive bays

To install components into the 5.25" drive bays, you must fi rst remove the top/

left chassis cover as described in the previous section. Refer to Chapter 6 for

details.

3. Installing CD-ROM and fl oppy disk drives

Refer to Chapter 6 if you need to install a CD-ROM and/or fl oppy disk drive to

the system.

2-9

AS4021M-32R User's Manual

4. Check the SAS disk 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.

5. Check the airfl ow

Airfl ow is provided by three hot-swap 8-cm chassis fans working in conjunction

with an air shroud. Two 8-cm exhaust fans are also mounted at the rear of the

chassis. The system component layout was carefully designed to promote suf-

fi cient airfl ow through the chassis. Also 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. Keep this in mind when you reroute them after working on the system.

6. Supplying power to the system

The last thing you must do is to provide input power to the system. Plug the

power cords from the power supplies unit into a high-quality power strip that of-

fers protection from electrical noise and power surges. It is recommended that

you use an uninterruptible power supply (UPS). Finally, depress the power on

button on the front of the chassis.

3-1 Overview

The control panel on the 4021M-32R has several LEDs and two buttons. There

are also two LEDs on each SAS drive carrier. These LEDs keep you constantly

informed of the overall status of the system and the activity and health of specifi c

components.

3-2 Control Panel Buttons

There are two push-buttons located on the front of the chassis: a power on/off

button and a reset button.

 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.

 RESET:

Use the reset button to reboot the system.

AS4021M-32R User's Manual

3-3 Control Panel LEDs

The control panel located on the front of the SC745TQ-R800 chassis has six LEDs

that provide you with critical information related to different parts of the system.

This section explains what each LED indicates when illuminated and any corrective

action you may need to take.

 Power:

LED should normally be on when the system is operating.

 HDD: Indicates IDE channel activity. On the 4021M-32R, this LED indicates

SAS drive activity when fl ashing.

 NIC1:

Indicates power is being supplied to the system's power supply. This

1

Indicates network activity on JLAN1 when fl ashing.

2

 NIC2: Indicates network activity on JLAN2 when fl ashing.

 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.

3-2

Chapter 3: System Interface

 Power Fail: Indicates a power supply module has failed. This should be

accompanied by an audible alarm. A backup power supply module will take the

load and keep the system running but the failed module will need to be replaced.

Refer to Chapter 6 for details on replacing the power supply. This LED should be

off when the system is operating normally.

3-4 SAS Drive Carrier LEDs

Each SAS drive carrier has two LEDs.

 Green: When illuminated, the green LED on the front of the SAS drive car-

rier indicates drive activity. A connection to the SAS backplane enables this LED

to blink on and off when that particular drive is being accessed.

 Red: The SES2 backplane activates the red LED to indicate a drive failure. If

one of the SAS drives fail, you should be notifi ed by your system management soft-

ware. Please refer to Chapter 6 for instructions on replacing failed SAS drives.

4-1 Electrical Safety Precautions

!

Basic electrical safety precautions should be followed to protect yourself from

harm and the 4021M-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

AS4021M-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 4021M-32R clean and free of clutter.

 The 4021M-32R weighs approximately 64 lbs (29.1 kg.) when fully loaded.

When lifting the system, two people at either end should lift slowly with their

feet spread out to distribute the weight. Always keep your back straight and

lift with your legs. Don't use the handles (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.

4-3

AS4021M-32R User's Manual

4-4 Operating Precautions

!

Care must be taken to assure that the chassis cover is in place when the

4021M-32R is operating to assure proper cooling. Out of warranty damage to

the 4021M-32R system can occur if this practice is not strictly followed.

Chapter 5

Advanced Serverboard Setup

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

H8DM3-2 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 chas-

sis 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.

AS4021M-32R User's Manual

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.

5-3

AS4021M-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 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)

 SAS cables (SAS0 ~ SAS7)

 Control Panel cable (JF1, see next page)

Connecting Power Cables

The H8DM3-2 has a 24-pin primary power supply connector designated "J1B1" for

connection to the ATX power supply. Connect the appropriate connector 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 8-pin Processor Power

connector at JPW1 and the 4-pin Auxiliary Power connector at JPW2.

5-5

AS4021M-32R 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.

Figure 5-4. Rear Panel I/O Ports

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. 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

AS4021M-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: 32 GB of registered ECC DDR2-667/533/400. If only one CPU

is installed, maximum supported memory is halved.

one PCI-Express x4 slot, one 64-bit 133 MHz PCI-X slot and two 64-bit 133/100 MHz

PCI-X slots. The 4021M-32R can support 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

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: O n t w o - p i n j u m p e r s , " C l o s e d "

means the jumper is on and "Open"

means the jumper is off the pins.

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.

Advanced Chassis Setup

This chapter covers the steps required to install components and perform simple

maintenance on the SC745TQ-R800 chassis. Following the component installation

steps in the order given will eliminate most common problems. If some steps are

unnecessary, skip ahead to the step that follows. Refer to Chapter 2 for instructions

on installing the system as a 4U rackmount.

Tools Required

The only tool you will need is a Philips screwdriver.

6-1 Static-Sensitive Devices

Static electrical discharge can damage electronic 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

static discharge.

Precautions

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

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

bag.

• Handle a board by its edges only; do not touch its components, peripheral chips,

memory modules or gold contacts.

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

• Put the serverboard, add-on cards and peripherals back into their antistatic bags

when not in use.

• For grounding purposes, make sure your computer chassis provides excellent

conductivity between the power supply, the case, the mounting fasteners and

the serverboard.

Unpacking

The serverboard is shipped in antistatic packaging. When unpacking the board,

make sure the person handling it is static protected.

6-3 System Fans

Three 8-cm chassis fans (located in the center of the chassis) provide cooling airfl ow

while two 8-cm exhaust fans expel hot air from the chassis. The chassis is also

fi tted with an air shroud to concentrate the fl ow of cool air over the areas of highest

generated heat. The fans should all be connected to headers on the serverboard

(see Chapter 5). Each power supply module also has a fan.

Fan Failure

Under normal operation, all three chassis fans, both exhaust fans and the power

supply fans run continuously. The chassis fans and the exhaust fans are hot-swap-

pable and can be replaced without powering down the system.

Replacing Chassis Fans

1. Identifying the failed fan

To locate and replace a failed chassis fan, begin by removing the top/left chassis

cover (see Chapter 2 for details on removing the cover). Locate the fan that has

stopped working.

2. Removing a hot-plug fan housing

Depress the locking tab on the failed fan: on a chassis fan, puch the tab on the side

of the housing inward, on the exhaust fan push down on the colored tab. With the

tab depressed, pull the unit straight out (see Figure 6-3). The wiring for these fans

has been designed to detach automatically.

3. Installing a new system fan

Replace the failed fan with an identical one (see Appendix for part numbers). Install

it in the same position and orientation as the one you removed; it should click into

place when fully inserted. Check that the fan is working then replace the top/left

side chassis panel.

Removing the air shroud

Under most circumstances you will not need to remove the air shroud to perform

any service on the system. However, if you wish to temporarily remove it (the air

shroud should always be in place when the system is operating), please follow

this procedure.

Begin by depressing the tabs at the front and rear of the shroud to unlock it, then

lift it up and out of the chassis (see Figure 6-4). To reinstall, simply position the

air shroud in its proper place and push it in until you hear it click.

SAS Drives

A total of eight SAS drives may be housed in the SC745TQ-R800 chassis. The

drive IDs are preconfi gured as 0 through 7 in order from bottom to top (or from left

to right if rackmounted). A bezel covers the drive area but does not need to be

removed to access the drives; simply swing open the bezel. If you wish to remove

the bezel piece, push on the three tabs on the inside of the left lip of the front chassis

cover. Then slightly swing out the same (left) side of the cover - about ½ inch only.

Remove by pushing on the open side of the cover to remove it from the chassis (do

not try to swing or pull it straight out after opening the left side).

Regardless of how many SAS drives are installed, all drive carri-

!

ers must remain in the drive bays to promote proper airfl ow.

1. Installing/removing hot-swap SAS drives

The SAS drive carriers are all easily accessible at the front of the chassis. These

drives are hot-swappable, meaning they can be removed and installed without

powering down the system. To remove a carrier, fi rst open the front bezel then

push the release button located beside the drive LEDs. Swing the handle fully out

and then use it to pull the unit straight out.

Note: Your operating system must have RAID support to enable the hot-swap

capability of the SAS drives.

2. 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 work to promote proper airfl ow for

the system. For this reason, even carriers without SAS drives must remain in the

server. If you need to add a new SAS drive, insert the 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 (see Figure 6-6).

Important! Use extreme caution when working around the SAS

backplane. Do not touch the backplane with any metal objects

!

3. SAS backplane

The SAS drives plug into a SAS backplane. Two iPass cables (CBL-0119L-02)

need to be connected from the serverboard to the appropriate connectors on the

backplane to support the eight SAS six drives. You cannot cascade the SAS

backplane.

and make sure no ribbon cables touch the backplane or obstruct

the airfl ow holes.

Installing Components in the 5.25"/3.5" Drive Bays

1. Drive bay confi guration

The 4021M-32R has two 5.25" and one 3.5" drive bays. Components such as an

extra fl oppy drive, IDE hard drives or CD-ROM drives can be installed into these

5.25" drive bays.

2. Mounting components in the drive bays

First power down the system and then remove the top/left chassis cover to access

the drive bays. With the cover off, remove the two or four screws that secure the

drive carrier to the chassis (one side only) then push the entire empty drive carrier

out from the back.

Adding a CD-ROM drive: remove the guide plates (one on each side) from the empty

drive carrier and screw them into both sides of the CD-ROM drive using the holes

provided. Then slide the CD-ROM into the bay and secure it to the chassis with

the drive carrier screws you fi rst removed. Attach the power and data cables to the

drive. Replace the top/left chassis cover before restoring power to the system.

Adding an IDE or fl oppy drive: to add one of these drives, install it into one of the

removed empty drive carriers with the printed circuit board side toward the carrier

so that the drive's mounting holes align with those in the carrier. Secure the drive

to the carrier with four screws then slide the assembly into the bay and secure it to

the chassis with the drive carrier screws you fi rst removed. Attach the power and

data cables to the drive. Replace the top/left chassis cover before restoring power

to the system.

Note: A red wire typically designates the location of pin 1. You should keep the

drive carriers inserted in any unused drive bays to reduce EMI and noise and to

facilitate the airfl ow inside the chassis.

Chapter 6: Advanced Chassis Setup

6-5 Power Supply

The SuperServer 4021M-32R has a redundant 800 watt 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. Re-

placement units can be ordered directly from Supermicro (see contact information

in the Preface). The hot-swap capability of the power supply modules allows you

to 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 unit. The

redundant feature will keep the system up and running while you replace the failed

hot-swap unit. Replace with the same model - (see Appendix D).

1. Removing the power supply

First unplug the power cord from the failed power supply unit. Then depress the

locking tab on the power supply unit and pull the unit straight out by the handle.

2. Installing a new power supply

Replace the failed module with another power supply module (must be the exact

same - refer to Appendix D for part number). Simply push the new power supply

unit into the power bay until you hear a click. Finish by plugging the AC power cord

back into the unit.

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 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.

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.

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.

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.
