About This Manual
This manual is written for system integrators, PC technicians and
knowledgeable PC users. It provides information for the installation and use of the
H8SMU serverboard. The H8SMU is based on the nVidia® MCP55 Pro chipset
and supports a single AMD Opteron 1000 Series AM2 type processor and up to 8
GB of DDR2-800/667/533 unbuffered ECC/non-ECC SDRAM.
Please refer to the serverboard specifications pages on our web site for updates on
supported processors (http://www.supermicro.com/aplus/). This product is intended
to be professionally installed.

the serverboard in a chassis. Also refer to this chapter to connect the floppy and
hard disk drives, the parallel and serial ports, the mouse and keyboard and the
twisted wires for the power and reset buttons and the system LEDs.
If you encounter any problems, see Chapter 3, which describes troubleshooting
procedures for the video, the memory and the setup configuration stored in CMOS.

1-2 Chipset Overview
The H8SMU motherboard 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 processor.
MCP55 Pro Media and Communications Processor
The MCP55 Pro is a single-chip, high-performance HyperTransport peripheral con-
troller. It includes a 28-lane PCI Express interface, an AMD Opteron 16-bit Hyper
Transport interface link, a four-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 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 efficient use of memory in
multi-processor systems. The end result is a significant increase in bandwidth
within the chipset.

H8SMU User’s Manual
1-3 PC Health Monitoring
This section describes the PC health monitoring features of the H8SMU. The
motherboard has an onboard System Hardware Monitor chip that supports PC
health monitoring.
Onboard Voltage Monitors for CPU core, 3.3V, +5Vin, +12Vin,
+5V standby and battery voltage
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 define 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 define 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 100A
and auto-sense voltage IDs. This will allow the regulator to run cooler and thus
make the system more stable.

Chapter 1: Introduction
1-11
1-4 Power Configuration 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.
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 motherboard.
Wake-On-LAN (JWOL)
Wake-On-LAN is defined 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 traffic is kept to
a minimum and users are not interrupted. The motherboard 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.

1-12
H8SMU User’s Manual
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 H8SMU accommodates 12V ATX power supplies. Although most power sup-
plies generally meet the specifications 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 Specification 1.1 or above. Additionally, in areas where
noisy power transmission is present, you may choose to install a line filter 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.
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.

Chapter 1: Introduction
1-13
1-6 Super I/O
The disk drive adapter functions of the Super I/O chip include a floppy 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 floppy 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 Configuration
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 flexibly adjusted
to meet ISA PnP requirements, which support ACPI.

H8SMU User’s Manual
1-7 UIO
The H8SMU is a specially-designed motherboard that features Supermicro's UIO
(Universal I/O) technology. UIO motherboards have PCI-Express slots (or UIO
slots on UIO risers) that can support any one of several types of UIO card types
to add SAS ports, additional LAN ports, Infiniband®, etc. to the motherboard. This
allows the user to tailor the motherboard to their own needs.
