This chapter provides a quick setup checklist to get your AS1020C-3 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 1020C-3 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 1020C-3 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 1020C-3. 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 1020C-3 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
AS1020C-3 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 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
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.).

AS1020C-3 User's Manual
2-4 Installing the System into a Rack
This section provides information on installing the 1020C-3 into a rack unit with the
rack rails provided. If the 1020C-3 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 1020C-3. 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 1020C-3 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

AS1020C-3 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.

Chapter 2: Server Installation
Installing the Server into a Telco Rack
If you are installing the 1020C-3 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.

AS1020C-3 User's Manual
2-5 Checking the Serverboard Setup
After you install the 1020C-3 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 1020C-3 (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 may have one or two processors already installed into the serverboard. Each
processor needs its own heatsink. See Chapter 5 for instructions on processor
and heatsink installation.
3. 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 1020C-3 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.
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.
2-8
Chapter 2: Server Installation
Figure 2-5. Accessing the Inside of the Server
2-6 Checking the Drive Bay Setup
Next, you should check to make sure the peripheral drives and the SAS drives have
been properly installed and all connections have been made.
1.Accessing the drive bays
All drives are accessable from the front of the server. For servicing the CD-ROM
and fl oppy drives, you will need to remove the top chassis cover. The SAS disk
drives can be installed and removed from the front of the chassis without remov-
ing 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 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.
2-9
AS1020C-3 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 SAS drive
carriers to keep you constantly informed of the overall status of the system as well
as the activity and health of specifi c components. There are also two buttons on
the chassis control panel 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 SC813TQ+-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.

4-1 Electrical Safety Precautions
!
Basic electrical safety precautions should be followed to protect yourself from
harm and the 1020C-3 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 SAS 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
AS1020C-3 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 (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.
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 1020C-3 clean and free of clutter.
The 1020C-3 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.
4-3
AS1020C-3 User's Manual
4-4 Operating Precautions
!
Care must be taken to assure that the chassis cover is in place when the
1020C-3 is operating to ensure proper cooling. Out of warranty damage to the
1020C-3 system can occur if this practice is not strictly followed.

Advanced Serverboard Setup
This chapter covers the steps required to install processors and heatsinks to the
H8DCR-3 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.

AS1020C-3 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 H8DCR-3 serverboard requires a chassis that can support extended ATX
boards of 12" x 13.05" in size, such as the SC813TQ+-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 serverboard tray in the chassis
Carefully mount the serverboard onto the serverboard 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 serverboard 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-
!
CPU Backplates
sor. Always connect the power cord last and always remove it be-
fore adding, removing or changing any hardware components.
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
Installing the Processor
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.
Chapter 5: Advanced Serverboard Setup
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: using a single processor only
is not recommended.

AS1020C-3 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).
Repeat these steps to install the second heatsink to CPU #2.

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)
SAS drive cables (JSM2)
Control panel cable (JF1, see next page)
Connecting Power Cables
The H8DCR-3 has a 20-pin primary power supply connector at "J1B4" 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 processor connec-
tor at JPW2. For systems with high load confi gurations, a third (auxiliary) power
connector at J32 should also be connected to your power supply.
5-5
AS1020C-3 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.

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 2-2). 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. 128 MB, 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 any memory modules.
*With Opteron 246 C-stepping CPUs and above.
Support
The H8DCR-3 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. However, 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 fol-
lowing pages.
5-7
AS1020C-3 User's Manual
Optimizing memory performance
With two processors 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 DDR333/266 and 16 GB for DDR400.
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

Notes: X indicates a populated DIMM slot. If adding four DIMMs (with two CPUs installed), the confi guration in rows 2 and 6 (with DIMMs spread over both CPUs) will result
in optimized performance.
5-7 Adding PCI Cards
1. PCI slots
The H8DCR-3 has two PCI-Express x8 slots, one 133 MHz PCI-X slot and one
100 MHz PCI-X expansion slots. Two riser cards are included with the server to
make two of these slots available in a 1U chassis format: one full height, half length
Universal 133 MHz PCI-X or PCI-Express x8 add-on card and one low-profi le
Universal 100 MHz PCI-X slot or PCI-Express x8 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
