1-2 Chipset Overview
The X10SLE-DF supports the Intel® Xeon E3-1200 v3, 4th-Generation Core i3,
Pentium, or a Celeron processor in an LGA1150 H3 socket. Built upon the func-
tionality and capability of the C224 Express chipset, the X10SLE-DF is optimized
for high-end, high-performance, Micro-Cloud server platforms.
The high-speed Direct Media Interface (DMI) featured in the Intel C224 Express
chipset supports high-speed Direct Media Interface (DMI) for chip-to-chip true
isochronous communication, providing up to 4 Gb/s of software-transparent data
transfer rate on each read/write direction. In addition, the X10SLE-DF also features
a TCO timer, which allows the system to recover from a software/hardware lock
and perform tasks, including Function Disable and Intruder Detect.
Intel C224 Express Chipset Features
•Direct Media Interface (up 10 Gb/s transfer, full duplex)
•Intel® Matrix Storage Technology and Intel Rapid Storage Technology
•Dual NAND Interface
•Intel I/O Virtualization (VT-d) Support
•Intel Trusted Execution Technology Support
•PCI Express 3.0 Interface (up to 8.0 GT/s)
•SATA Controller (up to 6Gb/sec)

X10SLE-DF User’s Manual
1-3 Special Features
Recovery from AC Power Loss
Basic I/O System (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.
1-4 PC Health Monitoring
This section describes the PC health monitoring features of the board. All boards
have an onboard System Hardware Monitoring chip that supports PC health monitor-
ing. An onboard voltage monitor will scan the following onboard voltages continu-
ously: CPU Vcore, 12V, 5V, 3.3V, 3.3VSB, memory, chipset, and battery voltages.
Once a voltage becomes unstable, a warning is given, or an error message is sent
to the screen. The user can adjust the voltage thresholds to dene the sensitivity
of the voltage monitor.
Fan Status Monitor with Firmware Control
PC health monitoring in the BIOS can check the RPM status of the cooling fans.
The onboard CPU and chassis fans are controlled by Thermal Management via
IPMI Firmware.
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-dened
threshold. The overheat circuitry runs independently from the CPU. Once the ther-
mal sensor detects that the CPU temperature is too high, it will automatically turn
on the thermal fans to prevent the CPU from overheating. The onboard chassis
thermal circuitry can monitor the overall system temperature and alert the user when
the chassis temperature is too high.
Note: To avoid possible system overheating, please be sure to provide
adequate airow to your system.
System Resource Alert
This feature is available when the system is used with SuperDoctor®III in the

Chapter 1: Introduction
1-11
Windows OS environment or used with SuperDoctor®II in Linux. SuperDoctor
is used to notify the user of certain system events. For example, you can also
congure SuperDoctor to provide you with warnings when the system temperature,
CPU temperatures, voltages and fan speeds go beyond predened thresholds.
1-5 ACPI Features
ACPI stands for Advanced Conguration and Power Interface. The ACPI specica-
tion denes a 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 also
provides a generic system event mechanism for Plug-and-Play, and an operating
system-independent interface for conguration control. ACPI leverages the Plug-and
-Play BIOS data structures, while providing a processor-architecture-independent
implementation that is compatible with Windows 7, Windows 8, and Windows 2008
operating systems.
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.
This motherboard accommodates SMC-proprietary power supplies. To provide
adequate power to your system, be sure to use power supplies recommended by
