H8DGU-LN4F+ Serverboard User’s Manual

1-4 Chipset Overview

The H8DGU-LN4F+ serverboard is based on the AMD SR5690/SP5100 chipset. This
chipset functions as a Media and Communications Processor (MCP). Controllers for
the system memory are integrated directly into AMD Opteron processors.

AMD SR5690/SP5100 Chipset

The AMD SR5690/SP5100 are each a single-chip, high-performance HyperT ransport
peripheral controller. It includes a 42-lane PCI Express interface, an AMD Opteron
16-bit Hyper Transport interface link, a six-port Serial AT A interface and a seven-port
USB 2.0 interface. This hub connects directly to the CPU.

HyperTransport Technology

HyperTransport technology is a high-speed, low latency point to point link that was
designed to increase the communication speed by a factor of up to 48x between
integrated circuits. This is done partly by reducing the number of buses in the
chipset to reduce bottlenecks and by enabling a more effi cient use of memory
in multi-processor systems. The end result is a signifi cant increase in bandwidth
within the chipset.

1-5 PC Health Monitoring

This section describes the PC health monitoring features of the H8DGU-LN4F+
serverboard. The serverboard has an onboard System Hardware Monitor chip that
supports PC health monitoring.

Onboard Voltage Monitors

The onboard voltage monitor will continuously scan crucial voltage levels. Once
a voltage becomes unstable, it will give a warning or send an error message to
the screen. Users can adjust the voltage thresholds to defi ne the sensitivity of the
voltage monitor. Real time readings of these voltage levels are all displayed in BIOS.

Fan Status Monitor with Firmware/Software Speed Control

The PC health monitor can check the RPM status of the cooling fans. The onboard
fans are controlled by thermal management via BIOS.

Chapter 1: Introduction

1-11

CPU Overheat/Fan Fail LED and Control

This feature is available when the user enables the CPU overheat/Fan Fail warning
function in the BIOS. This allows the user to defi ne an overheat temperature. When
this temperature is exceeded or when a fan failure occurs, the Overheat/Fan Fail
warning LED is triggered.

Auto-Switching Voltage Regulator for the CPU Core

The 5+1-phase-switching voltage regulator for the CPU core can support up to
AMD Opteron 6000SE series processors and auto-sense voltage IDs ranging from

0.8 V to 1.55V. This will allow the regulator to run cooler and thus make the system
more stable.

1-6 Power Confi guration Settings

This section describes the features of your motherboard that deal with power and
power settings.

Microsoft OnNow

The OnNow design initiative is a comprehensive, system-wide approach to system
and device power control. OnNow is a term for a PC that is always on but appears
to be off and responds immediately to user or other requests.

Slow Blinking LED for Suspend-State Indicator

When the CPU goes into a suspend state, the chassis power LED will start blinking
to indicate that the CPU is in suspend mode. When the user presses any key, the
CPU will wake-up and the LED will automatically stop blinking and remain on.

BIOS Support for USB Keyboard

If a USB keyboard is the only keyboard in the system, it will function like a normal
keyboard during system boot-up.

1-12

H8DGU-LN4F+ Serverboard User’s Manual

Main Switch Override Mechanism

The power button can function as a system suspend button. When the user
depresses the power button, the system will enter a SoftOff state. The monitor
will be suspended and the hard drive will spin down. Depressing the power button
again will cause the whole system to wake-up. During the SoftOff state, the power
supply provides power to keep the required circuitry in the system alive. In case the
system malfunctions and you want to turn off the power, just depress and hold the
power button for 4 seconds. The power will turn off and no power will be provided
to the motherboard.

1-7 Power Supply

As with all computer products, a stable power source is necessary for proper and
reliable operation. It is even more important for processors that have high CPU
clock rates.

The H8DGU-LN4F+ serverboard requires the use of proprietary power supplies.
Please refer to the pinout information for the power connectors in Section 6 of
Chapter 2 for detailed information on power requirements.

In areas where noisy power transmission is present, you may choose to install a
line fi lter to shield the computer from noise. It is recommended that you also install
a power surge protector to help avoid problems caused by power surges.

Warning: To prevent the possibility of explosion, do not use the wrong type of
onboard CMOS battery or install it upside down.

1-8 Super I/O

The disk drive adapter functions of the Super I/O Winbond® BMC chip includes a
data separator, write pre-compensation circuitry, decode logic, data rate selection,
a clock generator, drive interface control logic and interrupt and DMA logic. The
wide range of functions integrated onto the Super I/O greatly reduces the number
of components required for interfacing with fl oppy disk drives.

The Super I/O provides two high-speed, 16550 compatible serial communication
ports (UARTs), one of which supports serial infrared communication. Each UART
includes a 16-byte send/receive FIFO, a programmable baud rate generator,
complete modem control capability and a processor interrupt system. Both UARTs
provide legacy speed with baud rate of up to 115.2 Kbps as well as an advanced
speed with baud rates of 250 K, 500 K, or 1 Mb/s, which support higher speed
modems.

Chapter 1: Introduction

1-13

The Super I/O provides functions that comply with ACPI (Advanced Confi guration
and Power Interface), which includes support of legacy and ACPI power management
through a SMI or SCI function pin. It also features auto power management to reduce
power consumption.

The IRQs, DMAs and I/O space resources of the Super I/O can be fl exibly adjusted
to meet ISA PnP requirements, which support ACPI and APM (Advanced Power
Management).

2-2 Static-Sensitive Devices

Electrostatic Discharge (ESD) can damage electronic com ponents. To prevent
damage to your system board, it is important to handle it very carefully . The following
measures are generally suffi cient to protect your equipment from ESD.

Precautions

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

• Touch a grounded metal object before removing the board from the antistatic

bag.

• Handle the 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 motherboard 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 motherboard.

• Use only the correct type of CMOS onboard battery as specifi ed by the

manufacturer. Do not install the CMOS onboard battery upside down, which
may result in a possible explosion.

Unpacking

The motherboard is shipped in antistatic packaging to avoid static damage. When
unpacking the board, make sure the person handling it is static protected.

Chapter 2: Installation

2-3 Processor and Heatsink Installation

Warning: Exercise extreme caution when handling and installing the processor . Always

connect the power cord last and always remove it before adding, removing or changing
any hardware components.

Installation Procedure

Follow the procedures as listed below to install the motherboard into a chassis.

1. Install the processor(s) and the heatsink(s).

2. Install the motherboard in the chassis.

3. Install the memory and add-on cards.

4. Finally, connect the cables and install the drivers.

Installing the Processors

1. Begin by removing the cover plate
that protects the CPU. Lift the
lever on the CPU socket until it
points straight up.

2. With the lever raised, lift open the
silver CPU retention plate.

H8DGU-LN4F+ Serverboard User's Manual

2-6

Triangle

3. Use your thumb and your index
fi nger to hold the CPU. Locate
and align pin 1 of the CPU socket
with pin 1 of the CPU. Both are
marked with a triangle.

4. 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.

5. 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. Then, gently lower
the silver CPU retention plate into
place.

6. Carefully press the CPU socket
lever down until it locks into its
retention tab. For a dual-CPU
system, repeat these steps to
install another CPU into the
CPU#2 socket (and into CPU#2,
CPU#3 and #4 sockets for a
quad-CPU confi guration).

Note: In single and dual-CPU confi gurations, memory must be installed in the DIMM
slots associated with the installed CPU(s). Memory is limited to a maximum of 384
GB for single CPU and 768 GB for dual CPU confi gurations.

Chapter 2: Installation

2-7

Installing the Heatsinks

We recommend the use of active type heatsinks (except for 1U systems). Use any
onboard fan header for the CPU's heatsink fan. To install the heatsink, please follow
the installation instructions that are included with your heatsink package.

Note: Make sure the heatsink is placed so that the fi ns of the heatsink are in the
direction of the airfl ow in your system.

2-4 Mounting the Motherboard into a Chassis

All 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 motherboard
and the chassis match. Although a chassis may have both plastic and metal
mounting fasteners, metal ones are highly recommended because they ground
the motherboard to the chassis. Make sure that the metal standoffs click in or are
screwed in tightly.

Check the Compatibility of the Motherboard Ports and the I/O Shield

1. The H8DGU-LN4F+ serverboard requires a chassis that can support a board
of (LxW) 12.8" x 16.5" (325 x 419 mm) in size.

2. Make sure that the I/O ports on the motherboard align with their respective
holes in the I/O shield at the rear of the chassis.

Mounting the Motherboard onto the Tray in the Chassis

1. Carefully mount the motherboard onto the motherboard tray by aligning the
motherboard mounting holes with the raised metal standoffs in the tray.

2. Insert screws into all the mounting holes in the motherboard that line up with
the standoffs.

3. Then use a screwdriver to secure the motherboard to the mainboard
tray - tighten until just snug (if too tight you might strip the threads). Metal
screws provide an electrical contact to the motherboard ground to provide a
continuous ground for the system.

2-5 Installing Memory

Warning: Exercise extreme caution when installing or removing memory modules to

prevent any possible damage.

Installing Memory

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 2-1).

H8DGU-LN4F+ Serverboard User's Manual

2-8

2. Install to slots CPU1/DIMM1A, CPU1/DIMM2A, CPU1/DIMM3A and CPU1/
DIMM4A, etc. Always install in groups of four and in the numerical order of
the DIMM slots. See support information below.

3. Gently press down on the memory module until it snaps into place.

4. With four DIMMs installed, repeat step 2 to populate the CPU2 DIMM
slots. Always install four DIMMs to both CPU DIMM slots for more effi cient
operation.

Note: 1 GB, 2 GB, 4 GB, 8 GB, 16 GB or 32 GB size memory modules are
supported. It is highly recommended that you remove the power cord from the
system before installing or changing memory modules. Please refer to our web site
for memory that has been tested on the H8DGU-LN4F+ serverboard.

Memory Support

The H8DGU-LN4F+ serverboard supports single/dual/tri/quad-channel DIMMs with
DDR3-1600/1333/1066 Mhz speed SDRAM.

Populating four 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.

Maximum Memory

The H8DGU-LN4F+ serverboard supports up to128 GB of ECC/Non-ECC
Unbuffered or 768 GB of ECC Registered DIMM in 24 DIMM slots.

Figure 2-1. Installing DIMM into Slot

To Install: Insert

module vertically and
press down until it
snaps into place.
Pay attention to the
alignment notch at
the bottom.

To Remove: Use
your thumbs to gently
push the release tabs
near both ends of the
module. This should
release it from the
slot.

2-8 Jumper Settings

Explanation of Jumpers

To modify the operation of the
motherboard, 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 motherboard layout page
for jumper locations.

Note: On two-pin jumpers, "Closed"
means the jumper is on and "Open"
means the jumper is off the pins.

2-11 Enabling SATA RAID

Now that the hardware is set up, you must install the operating system and the
SATA RAID drivers, if you wish to use RAID with your SATA drives. The installation
procedure differs depending on whether you wish to have the operating system
installed on a RAID array or on a separate non-RAID drive. See the instructions
below for details.

Serial ATA (SATA)

Serial ATA (SATA) is a physical storage interface that employs a single cable with a
minimum of four wires to create a point-to-point connection between devices. This
connection is a serial link that supports a SATA transfer rate from 150 MBps. The
serial cables used in SATA are thinner than the traditional cables used in Parallel
ATA (PATA) and can extend up to one meter in length, compared to only 40 cm for
PATA cables. Overall, SATA provides better functionality than PATA.

Installing the OS/SATA Driver

Before installing the OS (operating system) and SA TA RAID driver , you must decide
if you wish to have the operating system installed as part of a bootable RAID array
or installed to a separate non-RAID hard drive. If on a separate drive, you may
install the driver either during or after the OS installation. If you wish to have the
OS on a SATA RAID array, you must follow the procedure below and install the
driver during the OS installation.

Building a Driver Diskette

You must fi rst build a driver diskette from Supermicro drivers for your system.
Drivers can be found at ftp://ftp.supermicro.com. (You will have to create this disk
on a computer that is already running and with the OS installed.)

Building a Driver Diskette

1. Install your system drives from the FTP website. A display as shown in Figure
2-7 will appear.

2. Click on the icon labeled “Build Driver Diskettes and Manuals” and follow the
instructions to create a fl oppy disk with the drivers on it.

3. Once it’s been created, remove the fl oppy and insert the installation CD for
the Windows Operating System you wish to install into the CD-ROM drive of
the new system you are about to confi gure.

Note: You need to have an external USB fl oppy when building the driver diskette.
Window’s Vista, Windows 2008 or later Windows OS systems can use a USB stick
instead of a fl oppy.

H8DGU-LN4F+ Serverboard User's Manual

Question: Why can't I turn off the power using the momentary power on/off
switch?

Answer: The instant power off function is controlled in BIOS by the Power Button

Mode setting. When the On/Off feature is enabled, the motherboard will have instant
off capabilities as long as the BIOS has control of the system. When the Standby
or Suspend feature is enabled or when the BIOS is not in control such as during
memory count (the fi rst screen that appears when the system is turned on), the
momentary on/off switch must be held for more than four seconds to shut down the
system. This feature is required to implement the ACPI features on the motherboard.

BIOS

4-1 Introduction

This chapter describes the AMIBIOS™ Setup utility for the H8DGU-LN4F+
serverboard. The 16 Mb AMI 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
message. 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.)
Settings 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.

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
procedure. 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.
