Recovery from AC Power Loss

BIOS provides a setting for you to determine how the system will respond when AC
power is lost and then restored to the system. You can choose for the system to
remain powered off (in which case you must press the power switch to turn it back
on) or for it to automatically return to a power- on state. See the Advanced BIOS
Setup section to change this setting. The default setting is Last State.

This section describes the PC health monitoring features of the X8DTU/X8DTU-F . All
have an onboard System Hardware Monitor chip that supports PC health monitoring.
An onboard voltage monitor will scan these onboard voltages continuously: Onboard
voltage monitors for CPU1 Vcore, CPU2 Vcore, CPU1 DIMM, CPU2 DIMM, 5V,
5VSB, 12V , -12V, 3.3Vcc, 3.3VSB, VBAT and Vtt. Once a voltage becomes unstable,
a warning is given or an error message is sent to the screen. Users can adjust the
voltage thresholds to defi ne the sensitivity of the voltage monitor.

Fan Status Monitor with Firmware Control

The PC health monitor can check the RPM status of the cooling fans. The onboard
CPU and chassis fans are controlled by Thermal Management via BIOS (under
Hardware Monitoring in the Advanced Setting).

Environmental Temperature Control

The thermal control sensor monitors the CPU temperature in real time and will turn
on the thermal control fan whenever the CPU temperature exceeds a user-defi ned
threshold. The overheat circuitry runs independently from the CPU. Once it detects
that the CPU temperature is too high, it will automatically turn on the thermal fan
control to prevent any overheat damage to the CPU. The onboard chassis thermal
circuitry can monitor the overall system temperature and alert users when the chas­sis temperature is too high.

To avoid possible system overheating, please be sure to provide adequate
airfl ow to your system.

System Resource Alert

This feature is availab le when used with Supero Do ctor III in the Windows OS
environment or used with Supero Doctor II in Linux. Supero Doctor is used to

notif y the user of cer tain system events. For example, you can also confi gure
Supero Doctor to provide you with warnings when the system temperature, CPU
temperat ures, volt ages a nd fan spe eds go beyon d a pre- defi ned range.

1-5 ACPI Features

ACPI stands for Advanced Confi guration and Power Interface. The ACPI specifi ca-
tion defi nes a fl exible and abstract hardware interface that provides a standard
way to integrate power management features throughout a PC system, including
its hardware, operating system and application software. This enables the system
to automatically turn on and off peripherals such as CD-ROMs, network cards, hard
disk drives and printers.

In addition to enabling operating system-directed power management, ACPI
provides a generic system event mechanism for Plug and Play and an operating
system-independent interface for confi guration control. ACPI leverages the Plug
and Play BIOS data structures while providing a processor architecture-independent
implementation that is compatible with both Windows 2003 and Windows 2008Op­erating Systems.

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.

1-6 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 X8DTU/X8DTU-F can accommodate 20-pin ATX power supplies. Although
most power supplies generally meet the specifi cations required by the CPU, some
are inadequate. In addition, two 12V 8-pin power connections are also required to
ensure adequate power supply to the system. Also your power supply must supply

1.5A for the Ethernet ports.
Warnings: 1. To prevent damage to the power supply or motherboard,

please use a power supply that contains a 20-pin and two 8-pin power
connectors. Be sure to connect these connectors to the 20-pin (JPW1)
and the two 8-pin (JPW2,JPW3) power connectors on the motherboard.
Failure in doing so will void the manufacturer warranty on your power sup­ply and motherboard. 2. To provide adequate power to the add-on cards

1-11

X8DTU/X8DTU-F User's Manual

installed on the motherboard, please connect the UIOP PWR connector
to the power supply.

It is strongly recommended that you use a high quality power supply that meets ATX
power supply Specifi cation 2.02 or above. It must also be SSI compliant (For more
information, please refer to the web site at http://www.ssiforum.org/). 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.

1-7 Super I/O

The Super I/O supports two high-speed, 16550 compatible serial communication
ports (UARTs). 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 an SMI or SCI function pin. It also features auto power management
to reduce power consumption.

1-8 Overview of the Winbond WPCM450 Controller (For
X8DTU-F Only)

The Winbond WPCM450 Controller is a Baseboard Management Controller (BMC)
that supports the 2D/VGA-compatible Graphics Core with the PCI interface,
Virtual Media, and Keyboard/Video/Mouse Redirection (KVMR) modules. With
blade-oriented Super I/O capability built-in, the WPCM450 Controller is ideal for
legacy-reduced server platforms.

The WPCM450 interfaces with the host system via a PCI interface to communicate
with the Graphics core. It supports USB 2.0 and 1.1 for remote keyboard/mouse/
virtual media emulation. It also provides LPC interface to control Super IO func­tions. The WPCM450 is connected to the network via an external Ethernet PHY
module.

The WPCM450 communicates with onboard components via six SMBus interfaces,
fan control, and Platform Environment Control Interface (PECI) buses.
