Chapter 1: Introduction

1-2 Chipset Overview

The H8DC8/H8DCi serverboard is based on the nVidia nForce Pro 2200/2050 and

AMD 8132 chipset. The nVidia nForce Pro 2200/2050 functions as Media and Com-

munications Processors (MCPs) and the AMD 8132 as a PCI-X Tunnel. Controllers

for the system memory are integrated directly into the AMD Opteron processors.

2200 Media and Communications Processor

This MCP is a single-chip, high-performance HyperTransport peripheral controller.

The 2200 includes a 20-lane PCI Express interface, an AMD Opteron 16-bit Hyper

Transport interface link, a four-port Serial ATA interface, a dual ATA133 bus master

interface, a USB 2.0 interface and support for 32-bit PCI slots. This hub connects

directly to CPU#1 and the 2050 MCP. The GLAN#1 port connects directly to the

2200 MCP.

2050 Media and Communications Processor

The 2050 is pin-to-pin compatible with the 2200. It includes a PCI Express inter-

face with 20 lanes and an AMD Opteron 16-bit Hyper Transport interface link. The

GLAN#2 connects directly to the 2050 MCP.

8132 HyperTransport PCI-X Tunnel

This hub includes AMD-speciﬁ c technology that provides two PCI-X bridges with

each bridge supporting a 64-bit data bus as well as separate PCI-X operational

modes and independent transfer rates. Each bridge supports up to ﬁ ve PCI masters

that include clock, request and grant signals. This hub connects to the processors

and through them to system memory.

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.

1-9

H8DC8/H8DCi User’s Manual

1-3 PC Health Monitoring

This section describes the PC health monitoring features of the H8DC8/H8DCi.

The serverboard has an onboard System Hardware Monitor chip that supports PC

health monitoring.

Onboard Voltage Monitors for two CPU cores, Hyper Transport (1.2V), two memory banks (2.5V), nVidia 2200/2050 chipset (1.5V)

The onboard voltage monitor will scan these voltages continuously. 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 moni-

tor. 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.

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, then, the Overheat/Fan

Fail warning LED is triggered.

Auto-Switching Voltage Regulator for the CPU Core

The 3-phase-switching voltage regulator for the CPU core can support up to 80A 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.

1-10

Chapter 1: Introduction

1-4 Power Conﬁ guration Settings

This section describes the features of your serverboard 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.

Main Switch Override Mechanism

When an ATX power supply is used, 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. Dur-

ing the SoftOff state, the ATX 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 serverboard.

Wake-On-LAN (JWOL)

Wake-On-LAN is deﬁ ned as the ability of a management application to remotely

power up a computer that is powered off. Remote PC setup, up-dates and access

tracking can occur after hours and on weekends so that daily LAN trafﬁ c is kept

to a minimum and users are not interrupted. The serverboard has a 3-pin header

(JWOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has

WOL capability. Wake-On-LAN must be enabled in BIOS. Note that Wake-On-LAN

can only be used with an ATX 2.01 (or above) compliant power supply.

1-11

H8DC8/H8DCi User’s Manual

Wake-On-Ring Header (JWOR)

Wake-up events can be triggered by a device such as the external modem ringing

when the system is in the SoftOff state. Note that external modem ring-on can only

be used with an ATX 2.01 (or above) compliant power supply.

1-5 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 of 1 GHz and faster.

The H8DC8/H8DCi accommodates 12V ATX power supplies. Although most power

supplies generally meet the speciﬁ cations required by the CPU, some are inad-

equate. A 2 amp current supply on a 5V Standby rail is strongly recommended.

It is strongly recommended that you use a high quality power supply that meets

12V ATX power supply Speciﬁ cation 1.1 or above. Additionally, 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.

Chapter 1: Introduction

1-6 Super I/O

The disk drive adapter functions of the Super I/O chip include a ﬂ oppy disk drive

controller that is compatible with industry standard 82077/765, a data separator,

write pre-compensation circuitry, decode logic, data rate selection, a clock genera-

tor, 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 supports two 360

K, 720 K, 1.2 M, 1.44 M or 2.88 M disk drives and data transfer rates of 250 Kb/s,

500 Kb/s or 1 Mb/s.

It also provides two high-speed, 16550 compatible serial communication ports

(UARTs), one of which supports serial infrared communication. Each UART in-

cludes 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.

The Super I/O supports one PC-compatible printer port (SPP), Bi-directional Printer

Port (BPP) , Enhanced Parallel Port (EPP) or Extended Capabilities Port (ECP).

The Super I/O provides functions that comply with ACPI (Advanced Conﬁ guration

and Power Interface), which includes support of legacy and ACPI power manage-

ment 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).

2-1 Static-Sensitive Devices

Electric Static 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 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.

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

turer. Do not install the CMOS onboard battery upside down, which may result

in a possible explosion.

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.

Installation Procedures

Follow the procedures as listed below to install the serverboard into a chassis:

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

2. Install the serverboard in the chassis.

3. Install the memory and add-on cards.

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

2-2 Processor and Heatsink Installation

Exercise extreme caution when handling and installing the proces-

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 at-

taching the heatsink retention modules. To install, begin by peeling off the release

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. See Figure 2-1. Note that for nForce 2050 (IO4) to function properly,

you will need to install CPU2.

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

fore adding, removing or changing any hardware components.

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

1. 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.

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 and the IO4 chip

will not function properly.

Installing the Heatsink Retention Modules

Chapter 2: Installation

Two heatsink retention modules (BKT-0005) and four screws are included in the

retail box. Once installed, these are used to help attach the heatsinks to the CPUs.

To install, position the module so that the CPU backplate standoffs insert through the

holes on the heatsink retention module and the four feet on the module contact the

serverboard. Secure the retention module to the backplate with two of the screws

provided. See Figure 2-1. Repeat for the second CPU socket. Note: BKT-0005

is included for use with non-proprietary heatsinks only. When installing proprietary

heatsinks, only BKT-0004 (CPU backplate) is needed. The BKT-0005 retention

module was designed to provide compatibility with clip-and-cam type heatsinks

from third parties.

Figure 2-1. CPU Backplate/Heatsink Retention Module Installation

Installing the Heatsink

We recommend the use of active type heatsinks (except for 1U systems). Use the

Fan7 header for the CPU1 fan and the Fan8 header for the CPU2 fan due to fan

monitoring and wiring considerations. To install the heatsinks, please follow the

installation instructions included with your heatsink package (not included).

2-3 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 H8DC8/H8DCi serverboard requires a chassis that can support extended ATX

boards of 12" x 13.05" in size. 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.

2-4 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, so the CPU2 DIMMs

cannot 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. It is highly recommended

that you remove the power cord from the system before installing or changing any

memory modules.
