Chapter 1: Introduction

1-2 Chipset Overview

The H8DMU+ serverboard is based on the nVidia MCP55 Pro chipset. The nVidia
MCP55 Pro functions as Media and Communications Processor (MCP). Controllers
for the system memory are integrated directly into the AMD Opteron processors.

MCP55 Pro Media and Communications Processor

The MCP55 Pro is a single-chip, high-performance HyperTransport peripheral con­troller. It includes a 28-lane PCI Express interface, an AMD Opteron 16-bit Hyper
Transport interface link, a six-port Serial ATA interface, a dual-port Gb Ethernet
interface, a single ATA133 bus master interface and a USB 2.0 interface. This hub
connects directly to CPU#1 and through that to CPU#2.

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.

H8DMU+ User’s Manual

1-3 PC Health Monitoring

This section describes the PC health monitoring features of the H8DMU+. The
serverboard has an onboard System Hardware Monitor chip that supports PC
health monitoring.

Onboard Voltage Monitors

The onboard voltage monitor will scan these voltages continuously: CPU cores,
Hyper Transport (1.2V), memory banks (1.8V), 1.5V, MCP55 Core, 3.3V, 12V, ­12V, 5V, VSB and battery voltage. 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.

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 5-phase-switching voltage regulator for the CPU core can support up to 120A
and auto-sense voltage IDs. 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. Dur­ing 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

H8DMU+ 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.

The H8DMU+ accommodates 12V ATX power supplies. Although most power sup­plies generally meet the specifi cations required by the CPU, some are inadequate.
Important: a 3A or greater current supply on the 5V Standby rail is required.

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.

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 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 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 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.

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.

2-2 Processor and Heatsink Installation

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.

CPU Backplates

Two CPU backplates (BKT-0011L) have been preinstalled to the serverboard to
prevent the CPU area of the serverboard from bending and to provide a base for
attaching the heatsink retention modules.

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

1. Begin by removing the cover plate
that protects the CPU. Lift the lever
on CPU socket #1 until it points straight
up. With the lever raised, lift open the
silver CPU retention plate.

2. 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.

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

5. Carefully press the CPU socket

lever down until it locks into its reten­tion 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
the CPU1 DIMM slots are addressable
for a maximum of 32 GB memory.

H8DMU+ User's Manual

Installing the Heatsink Retention Modules

Two heatsink retention modules (BKT-0012L) and four screws are included in the
retail box. Once installed, these are used to help attach the heatsinks to the CPUs.
To install, align the module with the standoffs of the preinstalled CPU backplate and
with the four feet on the module contacting 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-0012L is included for use with non-Supermicro heatsinks only. When
installing Supermicro heatsinks, only BKT-0011L (the pre-installed CPU backplate)
is needed. The BKT-0012L retention module was designed to provide compatibility
with clip-and-cam type heatsinks from third parties.

Installing the Heatsink

The use of active type heatsinks (except for 1U systems) are recommended. Con­nect the heatsink fans to the appropriate fan headers on the serverboard. To install
the heatsinks, please follow the installation instructions included with your heatsink
package (not included).
