1-3 Server Chassis Features
The SC812S-420C is a 1U chassis that features three hot-swap SCSI drive bays,
a slim CD-ROM drive, a slim 3.5" fl oppy drive and a revolutionary cooling design
that can keep today's most powerful processors running well below their tem-
perature thresholds. The following is a general outline of the main features of the
SC812S-420C chassis.
System Power
The SC812S-420C chassis includes a single 420W power supply.
SCSI Subsystem
The SCSI subsystem supports four 80-pin SCA Ultra320 SCSI hard drives. (Any
standard 1" drives are supported. SCA = Single Connection Attachment.) The SCSI
drives are connected to an SCA backplane that provides power, bus termination and
confi guration settings. The SCSI drives are also hot-swap units
Note: The operating system you use must have RAID support to enable the hot-
swap capability of the SCSI drives.
Control Panel
The SC812S-420C control panel provides important system monitoring and control
information. LEDs indicate power on, network activity, hard disk drive activity and
system overheat conditions. Also present are a main power button and a system
reset button.
I/O Backplane
The SC812S-420C is a 1U rackmount chassis. Its I/O backplane provides one full-
height full-length slot for a PCI add-on card, 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.)
Cooling System
A revolutionary cooling design has been designed into the SC812S-420C to provide
suffi cient cooling for dual processor confi gurations. The SC812S-420C includes
two heavy duty 10-cm blower fans located in the middle of the chassis. In the

Server Installation
2-1 Overview
This chapter provides a quick setup checklist to get your 1020A-8 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-8 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-8 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-8. 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-8 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-8 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 SCSI 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 tem-
perature of the rack environment may be greater than the ambient temperature
of the room. Therefore, consideration should be given to installing the equip-
ment 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.).

2-4 Installing the System into a Rack
This section provides information on installing the 1020A-8 into a rack. If the
1020A-8 has already been mounted into a rack, you can skip ahead to Sections
2-5 and 2-6. There are a variety of rack units on the market, which may mean the
assembly procedure will differ slightly. The following is a guideline for installing
the 1020A-8 into a rack with the rack rails provided. You should also refer to the
installation instructions that came with the rack unit you are using.
Identifying the Sections of the Rack Rails
You should have received two rack rail assemblies with the 1020A-8. Each of
these assemblies consist of three sections: an inner fi xed chassis rail that secures
to the 1020A-8 (A) and an outer fi xed rack rail that secures directly to the rack
itself (B). A sliding rail guide sandwiched between the two should remain attached
to the fi xed rack rail. (See Figure 2-1.) The A and B rails must be detached from
each other to install.
To remove the fi xed chassis rail (A), 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. Then depress the locking tab to pull the inner rail completely out.
Do this for both the left and right side rack rail assemblies.

2-4
Chapter 2: Server Installation
Installing the Chassis Rails
Position the fi xed chassis rail sections you just removed along the side of the
1020A-8 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 2-2). Repeat
this procedure for the other rail on the other side of the chassis. You will also need
to attach the rail brackets when installng into a telco rack.
Locking Tabs: As you have seen, both 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.
Installing the Rack Rails
Determine where you want to place the 1020A-8 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.

A+ Server 1020A-8 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 chas-
sis rails with the front of the rack rails. Slide the chassis rails into the rack rails,
keeping the pressure even on both sides (you may have to depress the locking
tabs when inserting). See Figure 2-3.
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.

Chapter 2: Server Installation
Installing the Server into a Telco Rack
If you are installing the 1020A-8 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.

A+ Server 1020A-8 User's Manual
2-5 Checking the Serverboard Setup
After you install the 1020A-8 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-8 (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 do not need to change
any jumpers or settings in BIOS.
4. Check the system memory
Your 1020A-8 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 an add-on card 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.
2-6 Checking the Drive Bay Setup
Next, you should check to make sure the peripheral drives and the SCSI drives
have been properly installed and all connections have been made.
2-8
Chapter 2: Server Installation
Figure 2-5. Accessing the Inside of the 1020A-8 Server
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 SCSI
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 SCSI disk drives
Depending upon your system's confi guration, your system may have one or
more drives already installed. If you need to install SCSI drives, please refer
to Chapter 6.
4. Check the airfl ow
Airfl ow is provided by two heavy duty 10-cm blower fans. The system compo-
nent 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. Take
2-9
A+ Server 1020A-8 User's Manual
care to reroute them in the same way when working on the system.
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.

System Interface
3-1 Overview
There are several LEDs on the control panel as well as others on the SCSI 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.
3-2 Control Panel Buttons
There are three push-button buttons located on the front of the chassis. These are
(in order from left to right) a reset button, an MNI (non-maskable interface) button
and a power on/off button.
RESET:
NMI:
a non-maskable interrupt to force the server into a halt state. This is used for
diagnostic purposes, and allows you to perform a memory download to determine
the cause of a problem.
Use the reset button to reboot the system.
NMI stands for "non-maskable interrupt". Pressing this button issues

A+ Server 1020A-8 User's Manual
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.
3-3 Control Panel LEDs
The control panel located on the front of the SC812S-420C 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.

Indicates power is being supplied to the system's power supply units.
3-4 SCSI Drive Carrier LEDs
Each SCSI drive carrier has two LEDs.
Green:
indicates drive activity. A connection to the SCSI SCA backplane enables this LED
to blink on and off when that particular drive is being accessed.
Red: A SAF-TE compliant backplane (standard on the 1020A-8) activates the
red LED, which indicates a drive failure. If one of the SCSI drives fail, you should
be notifi ed by your system management software. Please refer to Chapter 6 for
instructions on replacing failed SCSI drives.

System Safety
4-1 Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from
harm and the 1020A-8 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 SCSI 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-8 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-8 clean and free of clutter.
The 1020A-8 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.

A+ Server 1020A-8 User's Manual
4-4 Operating Precautions
Care must be taken to assure that the chassis cover is in place when the 1020A-8
is operating to ensure proper cooling. Out of warranty damage to the 1020A-8
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
H8DAR-8 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.

A+ Server 1020A-8 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-8 serverboard requires a chassis that can support extended ATX
boards of 12" x 13.05" in size, such as the SC812S-420C. 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.
Installing the CPU Backplates
Two CPU backplates (BKT-0004) are included in the retail box. The backplates
prevent the CPU area of the serverboard from bending and provide a base for
attaching the heatsink retention modules. To install, begin by peeling off the re-
lease paper to expose the adhesive. On the underside of the serverboard, locate
the two holes on either side of the CPU socket. Attach the adhesive side of the
backplate to the board by inserting the standoffs into the two holes and applying
light pressure so that the backplate sticks to the underside of the board. Repeat
for the second CPU socket.
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.

5-4 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

Connecting Power Cables
The H8DAR-8 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.

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 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
cannot be addressed if only a single CPU is installed. It is recommended that you
remove the power cord from the system before installing or changing DIMMs. 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.
5-7
A+ Server 1020A-8 User's Manual
Support
The H8DAR-8 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 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.
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 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 slot
The H8DAR-8 has one PCI-X 100 MHz expansion slot. A riser card is included
with the server: the CSE-RR1U-X riser fi ts into the 100 MHz PCI-X slot to support a
standard size (full-height, full-length) PCI-X add-on card (either 100 or 66 MHz).
2.PCI card installation
Before installing a PCI add-on card, see step 1, above. Begin by swinging the
release tab on the for the PCI shield out to the left. Insert the PCI card into the
riser 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.

Appendix A
BIOS Error Beep Codes
During the POST (Power-On Self-Test) routines, which are performed each time
the system is powered on, errors may occur.
Non-fatal errors are those which, in most cases, allow the system to continue the
boot-up process. The error messages normally appear on the screen.
Fatal errors are those which will not allow the system to continue the boot-up pro-
cedure. If a fatal error occurs, you should consult with your system manufacturer
for possible repairs.
These fatal errors are usually communicated through a series of audible beeps.
The numbers on the fatal error list, on the following page, correspond to the number
of beeps for the corresponding error. All errors listed, with the exception of Beep
Code 8, are fatal errors.
POST codes may be read on the debug LEDs located beside the LAN port on the
serverboard backplane. See the description of the Debug LEDs (LED1 and LED2)
in Chapter 5.
