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
H8SCM(-F) serverboard.
The H8SCM(-F) serverboard is based on the AMD® SR5650/SP5100 chipset and
supports one AMD Socket C32 type processor with up to 32 GB of ECC/Non-ECC
UDIMM or up to 128 GB of ECC RDIMM SDRAM memory.The H8SCM serverboard
does not have IPMI capability, whereas the H8SCM-F serverboard does.
Please refer to the motherboard specifications pages on our web site for updates on
supported processors (http://www.supermicro.com/aplus/). This product is intended
to be professionally installed.
Manual Organization
Chapter 1 includes a checklist of what should be included in your motherboard
box, describes the features, specifications and performance of the motherboard
and provides detailed information about the chipset.

H8SCM(-F) SERVERBOARD USER'S MANUAL
1-4 Chipset Overview
The H8SCM(-F) serverboard is based on the AMD SR5650/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 SR5650/SP5100 Chipset
TheAMDSR5650/SP5100 are each a single-chip, high-performance HyperTransport
peripheral controller. It includes a 22-lane PCI Express interface, an AMD Opteron
16-bit Hyper Transport interface link, a six-port SerialATAinterface 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 efficient use of memory
in multi-processor systems. The end result is a significant increase in bandwidth
within the chipset.
1-5 PC Health Monitoring
This section describes the PC health monitoring features of the H8SCM(-F)
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 define 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 define 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-phase-switching voltage regulator for the CPU core can support up to
AMD Opteron 4000 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 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.
Note: To wake up the system from an S4 state by the USB keyboard/mouse, please
connect the keyboard/mouse to USB port 0/1 at the rear I/O side.

1-12
H8SCM(-F) 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.
Wake-On-LAN (WOL)
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
(WOL) 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.
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 H8SCM(-F) serverboard requires the use of proprietary power supplies. Please
refer to the pinout information for the power connectors in Section 7 of Chapter 2
for detailed information on power requirements.
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.

Chapter 1: Introduction
1-13
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 floppy 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.
The Super I/O provides functions that comply with ACPI (Advanced Configuration
andPowerInterface),whichincludes supportof legacyandACPIpowermanagement
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 and APM (Advanced Power
Management).
