Memory is supported in both interleaved and non-interleaved conﬁ gurations. See

Section 5-6 for details.

Serial ATA

A Marvell 88SX6041 "Hercules II" SATA controller is integrated onboard the

H8DAR-T to provide a four-port Serial ATA subsystem, which is RAID 0 and 1

supported. The Serial ATA drives are hot-swappable units.

Note: The operating system you use must have RAID support to enable the hot-

swap capability and RAID function of the Serial ATA drives.

PCI Expansion Slots

Two riser cards have been included with the server to support add-on PCI ex-

pansion cards. The CSE-RR1U-X riser ﬁ ts into the 133 MHz PCI-X #6 slot on

the H8DAR-T to support a full-height, half-length PCI-X add-on card. The CSE-

RR1U-XLP ﬁ ts into the 133 MHz PCI-X #7 slot to support one low proﬁ le PCI-X

add-on card.

1-3 Server Chassis Features

The SC813T+-500 is our third-generation 1U chassis and features four hot-swap

Serial ATA drive bays, a slim CD-ROM drive, a slim 3.5" ﬂ oppy drive and a revo-

lutionary cooling design that can keep today's most powerful processors running

well below their temperature thresholds. The following is a general outline of the

main features of the SC813T+-500 chassis.

System Power

The SC813T+-500 chassis includes a single 500W cold-swap power supply.

Serial ATA Subsystem

For the 1020A-T, the SC813T+-500 chassis was designed to support four Serial

ATA hard drives, which are hot-swappable units. RAID 0 and RAID 1 levels are

supported.

Note: The system's operating system must have RAID support to enable the hot-

swap capability of the Serial ATA drives.

Control Panel

The control panel provides important system monitoring and control information.

LEDs indicate power on, network activity, hard disk drive activity and system over-

heat conditions. Also present are main power and system reset buttons.

I/O Backplane

The SC813T+-500 is a 1U rackmount chassis. Its I/O backplane provides one

full-height, half-length and one low proﬁ le slot for PCI add-on cards, one COM port

(the other is internal), one VGA port, two USB ports, PS/2 mouse and keyboard

ports and two Ethernet (LAN) ports. (See Figure 1-2.)

1-4

Chapter 1: Introduction

Cooling System

The SC813T+-500 chassis' revolutionary cooling design has been optimized to

provide sufﬁ cient cooling for dual processor conﬁ gurations. The chassis includes

four counter-rotating 4-cm fans located in the middle of the chassis. In the event

of a fan failure, the ambient air temperature inside the chassis will rise and activate

an overheat LED (fan speed is controlled by the system temperature).

A fan speed control setting in BIOS allows chassis fan speed to be determined by

system temperature [recommended setting is 3-pin (Server)].

Server Installation

2-1 Overview

This chapter provides a quick setup checklist to get your A+ 1020A-T system 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 1020A-T 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 1020A-T 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 1020A-T. 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 1020A-T 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

A+Server 1020A-T 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 Serial ATA 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 consid-

eration 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 con-

nections other than the direct connections to the branch circuit (i.e. the use of

power strips, etc.).

2-3

A+Server 1020A-T User's Manual

2-4 Installing the System into a Rack

This section provides information on installing the 1020A-T into a rack unit with the

rack rails provided. If the 1020A-T 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. You should also refer

to the installation instructions that came with the rack unit you are using.

Identifying the Sections of the Rails

You should have received a rack mounting kit with the 1020A-T. The kit includes

two sets of chassis rails (four pieces total, two of which are already installed on

the chassis) and two sets of rack rails (four pieces total). Figure 2-1 displays the

two right-side chassis rails and the two right-side rack rails. Note that two of the

four chassis rails (Chassis Rail 1) are already attached to the chassis.

Installing the Rack Rails

Begin by joining one set of rack rails corresponding to either the left or the right side

of the rack. Do this by aligning the studs of one rail with the holes of the other rail.

Push the studs into the grooved holes and then push the rail to slide the studs to

the end of the groove. Repeat this with the rack rails used for the other side.

Next, determine where you want to place the 1020A-T in the rack. (See Rack

and Server Precautions in Section 2-3.) Position the assembled rack rails at the

desired location in 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.

Locking Tabs: Both of the two chassis rails on each side have a locking tab (four

total), 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 operating position.

Secondly, these tabs also lock the server in place when extended from the rack.

This prevents the server from coming completely out of the rack when you pull it

out for servicing. The two sets of locking tabs mean there are two locked positions

when the chassis is extended from the rack, allowing easy access when servicing

the system. Note that on one side, you push the locking tab up to release it and

on the other side you push it down to release.

2-4

Chapter 2: Server Installation

Installing the Chassis Rails

Two of the chassis rails (Chassis Rail 1) should have already been preattached

- one to each side of the chassis. Attach the second set of chassis rails (Chassis

Rail 2) directly to the chassis with the screws provided. Chassis Rail 2 should

be positioned just behind Chassis Rail 1 (see Figure 2-2). Do this for both sides

of the chassis.

Figure 2-1. Identifying the Sections of the Rails

Figure 2-2. Installing Chassis Rails

2-5

A+Server 1020A-T User's Manual

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 lock-

ing tabs when inserting). See Figure 2-3.

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

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

the front of the server to the rack.

Figure 2-3. Installing the Server into a Rack

2-6

Chapter 2: Server Installation

Installing the Server into a Telco Rack

If you are installing the 1020A-T into a Telco type rack, follow the directions given

on the previous pages for rack installation. The only difference 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.

Figure 2-4. Installing the Server into a Telco Rack

2-7

A+Server 1020A-T User's Manual

2-5 Checking the Serverboard Setup

After you install the A+ 1020A-T 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 1020A-T (see Figure 2-5)

First, release the retention screws that secure the unit to the rack. Grasp the two

handles on either side and pull the unit straight out until it locks (you will hear

a "click"). Next, depress the two buttons on the top of the chassis to release

the top cover. There is a large rectangular recess in the middle front of the top

cover to help you 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.

2. Check the CPUs (processors)

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

Each processor needs its own heatsink. See Chapter 5 for instructions on pro-

cessor and heatsink installation.

3. CPU Speed

The CPU speed should automatically be detected so you will not need to change

any jumpers or settings in the BIOS Setup utility.

4. Check the system memory

Your 1020A-T 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.

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.

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 CD-ROM

and ﬂ oppy drives, you will need to remove the top chassis cover. The Serial ATA

disk drives can be installed and removed from the front of the chassis without

removing the top chassis cover or powering down the system.

2. CD-ROM and ﬂ oppy disk drives

A slim CD-ROM and a ﬂ oppy drive should be preinstalled in your server. Refer

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

system.

3. Check the SATA disk drives

Depending upon your system's conﬁ guration, your system may have one or

more drives already installed. If you need to install Serial ATA drives, please

refer to Chapter 6.

2-9

A+Server 1020A-T User's Manual

4. Check the airﬂ ow

Airﬂ ow is provided by four sets of counter-rotating 4-cm fans. The system com-

ponent layout was carefully designed to direct the 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 power to the system. Plug the power

cord from the power supply module 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). Finish by depressing the power

button on the front of the chassis to start the system.

3-1 Overview

There are several LEDs on the control panel as well as others on the Serial ATA

drive carriers to keep you constantly informed of the overall status of the system

as well as the activity and health of speciﬁ c components. There are also two but-

tons on the chassis control panel and an on/off switch on the power supply. This

chapter explains the meanings of all LED indicators and the appropriate response

you may need to take.

3-2 Control Panel Buttons

There are two push-buttons located on the front of the chassis. These are (in

order from left to right) a reset button and a power on/off button.

 Reset:

 Power: The main power switch is used to apply or remove power from the

power supply to the server system. Turning off system power with this button

removes the main power but keeps standby power supplied to the system.

Use the reset switch to reboot the system.

3-3 Control Panel LEDs

The control panel located on the front of th SC813T+-500 chassis has ﬁ ve 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.



Overheat/Fan Fail: When this LED ﬂ ashes it indicates a fan failure. When

on continuously (on and not ﬂ ashing) 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 overheat condition exists.

 NIC2: Indicates network activity on GLAN2 when ﬂ ashing .

 NIC1: Indicates network activity on GLAN1 when ﬂ ashing.

3-2

Chapter 3: System Interface

 HDD: Indicates IDE channel activity. On the 1020A-T this light indicates

SATA and/or CD-ROM drive activity when ﬂ ashing.

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

units. This LED should normally be illuminated when the system is operating.

3-4 Serial ATA Drive Carrier LED

Each Serial ATA drive carrier has a green LED. When illuminated, this green LED

(on the front of the Serial ATA drive carrier) indicates drive activity. A connec-

tion to the Serial ATA backplane enables this LED to blink on and off when that

particular drive is being accessed.

Note: The second LED on the SATA carriers is not used.

4-1 Electrical Safety Precautions

Basic electrical safety precautions should be followed to protect yourself from

harm and the 1020A-T 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 CD-ROM and ﬂ oppy drives (not necessary for Serial ATA

drives). When disconnecting power, you should ﬁ rst power down the system

with the operating system and then unplug the power cords from all the power

supply modules 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.

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

plugged into grounded electrical outlets.

4-1

A+ Server 1020A-T User's Manual

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

battery is installed upside down, which will reverse its polarities. 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. See Figure 4-1.

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

ROM drive. To prevent direct exposure to the laser beam and hazardous

radiation exposure, do not open the enclosure or use the unit in any

unconventional way.

4-2 General Safety Precautions

Follow these rules to ensure general safety:

 Keep the area around the 1020A-T clean and free of clutter.

 The 1020A-T weighs approximately 38 lbs (17.3 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.

 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.

 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.

4-2

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.

Chapter 4: System Safety

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

bag.

 Do not let components or PCBs come into contact with your clothing, which

may retain a charge even if you are wearing a wrist strap.

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

chips, memory modules or contacts.

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

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

not in use.

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

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

the serverboard.

4-4 Operating Precautions

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

1020A-T is operating to ensure proper cooling. Out of warranty damage to the

1020A-T system can occur if this practice is not strictly followed.

Figure 4-1. Installing the Onboard Battery

Chapter 5: Advanced Serverboard Setup

Chapter 5

Advanced Serverboard Setup

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

H8DAR-T 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.

5-1

A+ Server 1020A-T User's Manual

5-2 Mounting the Serverboard into a Chassis

All serverboards and motherboards have standard mounting holes to ﬁ t different

types of chassis. Make sure that the locations of all the mounting holes for both

the serverboard and the chassis match. Although a chassis may have both plastic

and metal mounting fasteners, metal ones are highly recommended because they

ground the serverboard to the chassis. Make sure that the metal standoffs click in

or are screwed in tightly.

1. Check the compatibility of the serverboard ports and the I/O shield

The H8DAR-T serverboard requires a chassis that can support extended ATX

boards of 12" x 13.05" in size, such as the SC813T+-500. Make sure that the I/O

ports on the serverboard align with their respective holes in the I/O shield at the

rear of the chassis.

2. Mounting the serverboard onto the mainboard tray in the chassis

Carefully mount the serverboard onto the mainboard tray by aligning the serverboard

mounting holes with the raised metal standoffs in the tray. Insert screws into all

the mounting holes in the serverboard that line up with the standoffs. Then use a

screwdriver to secure the serverboard to the mainboard tray - tighten until just snug

(if too tight you might strip the threads). Metal screws provide an electrical contact

to the serverboard ground to provide a continuous ground for the system.

5-3 Processor and Heatsink Installation

Exercise extreme caution when handling and installing the proces-

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

fore adding, removing or changing any hardware components.

CPU Backplates

Two CPU backplates (BKT-0004) have been preinstalled to the underside of the

serverboard. These backplates prevent the CPU area of the serverboard from

bending and provide a base for attaching the CPU heatsinks.

5-2

Chapter 5: Advanced Serverboard Setup

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

1. Lift the lever on CPU socket #1 until

it points straight up.

2. Use your thumb and your index ﬁ n-

ger to hold the CPU. Locate pin 1 on

the CPU socket and pin 1 on the CPU.

Both are marked with a triangle.

Triangles

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.

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.

5. Gently press the CPU socket lever

down until it locks in the plastic 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

CPU 1 DIMM slots are addressable.

5-3

A+ Server 1020A-T User's Manual

Installing the Heatsinks

To install the heatsink (SNK-P0012, optional), do not apply any thermal compound

to the heatsink or CPU die - the proper amount has already been applied. Place the

heatsink directly on the CPU so that the two mounting holes are aligned with those

on the CPU backplate. Make sure the heatsink sits completely ﬂ at on the CPU - if

not completely ﬂ at, the space between the two will degrade the heat dissipation

function of the heatsink, which may cause the processor to overheat. Screw in the

two screws until just snug (do not fully tighten), then ﬁ nish by fully tightening both

screws (see Figure 5-1).

If installing two processors, repeat these steps to install the second processor in

the CPU #2 slot.

Figure 5-1. Installing Heatsinks

5-4

Chapter 5: Advanced Serverboard Setup

5-4 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.

 CD-ROM cable (JIDE#1)

 Floppy Drive cable (JFDD1)

 Serial ATA cables (JS1, JS11, JS12, JS13)

 Control Panel cable (JF1, see next page)

Connecting Power Cables

The H8DAR-T has a 24-pin primary power supply connector "J1B4" at designated

"ATX Power" 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 Secondary ATX

Power connection at JPW2. For systems with high load conﬁ gurations, a third

power connector at J32 should also be connected to your power supply.

5-5

A+ Server 1020A-T User's Manual

Connecting the Control Panel

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

5-2 for the pin locations of the various front control panel buttons and LED indica-

tors and refer to section 5-9 for details. 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 5-3. Rear Panel I/O Ports

5-6 Installing Memory

CAUTION

Exercise extreme care when installing or removing memory modules

to prevent any possible damage.

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 5-4). 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 CPU2 DIMMs can-

not be addressed if only a single CPU is installed. 128 MB, 256 MB, 512 MB, 1

GB, 2 GB* and 4 GB* memory modules are supported.

*With Opteron 246 C-stepping CPUs and above.

Support

The H8DAR-T supports single or dual-channel, registered ECC DDR400/333/266

SDRAM.

Both interleaved and non-interleaved memory are supported, so you may populate

any number of DIMM slots (see note on previous 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).

5-7

A+ Server 1020A-T User's Manual

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.

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 (two CPUs): 32 GB for DDR266 and 16 GB for DDR400/333.

If only one CPU is installed, maximum supported memory capacity is halved (16

GB for DDR266 and 8 GB for DDR400/333).

Figure 5-4. Side and Top Views of DDR Installation

To Install:

Insert module vertically and press down until it snaps into place. The release tabs should close - if they do not you should close them yourself.

Note the notch in the slot and on the bottom of the DIMM. These prevent the DIMM from being installed incorrectly.

To Remove:

Use your thumbs to gently push each release tab outward to release the DIMM from the slot.

5-7 Adding PCI Cards

1. PCI slots

The H8DAR-T has two PCI-X 133 MHz expansion slots. Two riser cards are in-

cluded with the server to make both PCI-X slots available in a 1U chassis format:

the CSE-RR1U-X riser ﬁ ts into the PCI-X slot #6 to support a full-height, half-length

PCI-X add-on card and the CSE-RR1U-XLP riser ﬁ ts into the PCI-X slot #7 to

support a low proﬁ le PCI-X add-on card.

2. PCI card installation

Before installing a PCI add-on card, make sure it conforms to the correct riser

card (see step 1, above).

Begin by swinging the release tab on the PCI shield that corresponds to the riser

card/PCI-X slot you wish to populate. Insert the PCI card into the correct riser

card (depending on whether it is a standard or low-proﬁ le card), pushing down

with your thumbs evenly on both sides of the card. Finish by pushing the release

tab back to its original (locked) position. Follow this procedure when adding a

card to either slot.

5-10 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

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.

Chapter 5: Advanced Serverboard Setup

Note 1: On two-pin jumpers, "Closed"

means the jumper is on and "Open"

means the jumper is off the pins.

CMOS Clear

JBT1 is used to clear CMOS 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.

in the order given to eliminate the most common problems encountered. If some

steps are unnecessary, skip ahead to the next step.

Tools Required

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

Philips screwdriver.

6-1 Static-Sensitive Devices

Electricstatic 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.

Chapter 6: Advanced Chassis Setup

6-3 System Fans

Four high-performance, counter-rotating 4-cm fans provide all the cooling needed

for the 1020A-T. Each fan is actually made up of two fans joined back-to-back that

rotate in opposite directions. This counter-rotating action generates exceptional

airﬂ ow airﬂ ow while dampening vibration levels.

These fans can adjust their speed according to the heat level sensed in the system,

which results in more efﬁ cient and quieter fan operation. Fan speed is controlled

by a BIOS setting (see Chapter 7).

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

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 (see instructions on p. 2-8) while the

system is still running to determine which of the four fan units has failed. Then

power down the system before replacing a fan. Removing the power cord(s) is

also recommended as a safety precaution.

Replacing System Cooling Fans

1. Removing a fan

After turning off the power to the system, ﬁ rst remove the chassis cover and unplug

all the fan cables from the serverboard. Grasp the rectangular housing that holds

the fan units and lift it out of the chassis (see Figure 6-2). Push the failed fan unit

out through the bottom of the fan housing.

2. Installing a new fan

Replace the failed fan with an identical 4-cm, 12 VDC fan (p/n FAN-0083). Push

the new fan into the vacant space in the housing while making sure the arrows on

the top of the fan (indicating direction of airﬂ ow) point in the same direction as the

arrows on the other fans. Reposition the fan housing on the mounting posts in the

chassis, then reconnnect the fan wires to the same fan headers you removed them

from. Power up the system and check that the fan is working properly and that the

LED on the control panel has turned off. Finish by replacing the chassis cover.

If your system has a front bezel (optional) attached to the chassis, you must ﬁ rst

remove it to gain access to the drive bays. To remove the bezel, ﬁ rst unlock the

front of the chassis then press the release knob (see Figure 6-3). Carefully re-

move the bezel with both hands. A ﬁ lter located within the bezel can be removed

for replacement/cleaning. It is recommended that you keep a maintenance log of

ﬁ lter cleaning/replacement, since its condition will affect the airﬂ ow throughout the

whole system.

Accessing the Drive Bays

Serial ATA Drives: Because of their hotswap capability, you do not need to access

the inside of the chassis or power down the system to install or replace Serial ATA

drives. Proceed to the next step for instructions.

CD-ROM/Floppy Disk Drives: For installing/removing a CD-ROM or ﬂ oppy disk

drive, you will need to gain access to the inside of the 1020A-T by removing the

top cover of the chassis. Proceed to the "CD-ROM and Floppy Drive Installation"

section later in this chapter for instructions.

Note: Only a "slim" CD-ROM drive will ﬁ t into the 1020A-T.

Serial ATA Drive Installation

1. Mounting a Serial ATA drive in a drive carrier

The Serial ATA 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

Serial ATA drive bays. For this reason, even empty carriers without Serial ATA

drives installed must remain in the chassis. To add a new Serial ATA 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

six screws, as shown in Figure 6-4.

Figure 6-4. Mounting an SATA Drive in a Carrier

Use caution when working around the Serial ATA 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 Serial ATA hard drives are

installed, all drive carriers must remain in the drive bays to main-

tain proper airﬂ ow.

6-6

Chapter 6: Advanced Chassis Setup

2. Installing/removing hot-swap SATA drives

The SATA 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 6-5).

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

pability of the SATA drives.

Figure 6-5. Removing an SATA Drive from the Server

Serial ATA Power Cables

Serial ATA power cables should be routed so that they do not block the airﬂ ow

through the chassis. See the motherboard layout diagram for the location of the

cable connections.

Serial ATA Backplane

The Serial ATA 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.

A+ Server 1020A-T User's Manual

CD-ROM and Floppy Drive Installation

The top cover of the chassis must be opened to gain full access to the CD-ROM

and ﬂ oppy drive bays. The 1020A-T accomodates only slim-line CD-ROM drives.

Side mounting brackets are needed to mount a slim-line CD-ROM drive in the

1020A-T server.

You must power down the system before installing or removing a ﬂ oppy or CD-ROM

drive. 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.

With the chassis cover removed, unplug the power and data cables from the drive

you want to remove. Then locate the locking tab at the rear of the drive. It will be

on the left side of the drive when viewed from the front of the chassis. Pull the tab

away from the drive and push the drive unit out the front of the chassis. Add a new

drive by following this procedure in reverse order. You may hear a faint *click* of the

locking tab when the drive is fully inserted. Remember to reconnect the data and

power cables to the drive before replacing the chassis cover and restoring power

to the system. Please be aware of the following:

• 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.

Chapter 6: Advanced Chassis Setup

6-5 Power Supply

The 1020A-T has a single 500 watt power supply, which is auto-switching capable.

This enables it to automatically sense and operate at a 100v to 240v input voltage.

An amber light will be illuminated on the power supply when the power is off. An

illuminated green light indicates that the power supply is operating.

Power Supply Failure

If the power supply unit fails, the system will shut down and you will need to re-

place the unit. Replacement units can be ordered directly from the manufacturer.

As there is only one power supply unit in the 1020A-T, power must be completely

removed from the server before removing and replacing the power supply unit for

whatever reason.

Removing/Replacing the Power Supply

1. Removing the power supply

First turn the power switch on the control panel off, then unplug the power cord

from the system. Remove the chassis cover by pressing the two release buttons

on the top of the chassis (near the front) and push the chassis top rearward about

one inch. To remove the failed power unit, push the beige colored release tab to

the right and then carefully lift the unit up about 1/2 inch only. If you lift too high,

you may damage the power distribution board that the other end of the unit is

connected to. Then, pull the power unit straight back to unplug it from the power

distribution board. See Figure 6-6.

2. Installing a new power supply

Replace the failed unit with another unit of the same input voltage, output voltage

and wattage. It is highly recommended to replace it with exactly the same model

power supply. Carefully insert the new unit into position to plug it into the power

distribution board, making sure you are not holding it at too great an angle, which

may damage the power distribution board. Push it completely into the power

distribution board and seat it in the chassis. When correctly installed it should be

laying ﬂ at - make sure the end of the power supply is not sitting on the stop in the

chassis. Reconnect the power cord, replace the chassis top cover and reposition

the unit back into the rack. Finish by depressing the power button on the chassis

front control panel.

This chapter describes the AMIBIOS™ Setup utility for the H8DAR-T. 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.

Note: fan speed is controlled by the "Fan Speed Control Modules" setting in BIOS.

The recommended setting for the A+ 1020A-T is "3-pin (Server)". You may have to

reset this setting after ﬂ ashing BIOS or loading BIOS default values.

7-2 Main Setup

When you ﬁ rst enter AMI BIOS Setup Utility, you will see the Main setup screen.

You can always return to the Main setup screen by selecting the Main tab on the

top of the screen.

The Main Setup 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.

In the LBA mode, the maximum drive capacity is 137 GB. For drive capacities of

over 137 GB, your system must be equipped with 48-bit LBA mode addressing.

If not, contact your manufacturer or install an ATA/133 IDE controller card that

supports 48-bit LBA mode. The options are Disabled and Auto.

Block (Multi-Sector Transfer)

Block mode boosts IDE drive performance by increasing the amount of data

transferred. Only 512 bytes of data can be transferred per interrupt if block mode

is not used. Block mode allows transfers of up to 64 KB per interrupt. Select

"Disabled" to allow the data to be transferred from and to the device one sec-

tor at a time. Select "Auto" to allows the data transfer from and to the device

occur multiple sectors at a time if the device supports it. The options are Auto

and Disabled.

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
