Chapter 1: Introduction
1.3 System Health Monitoring
This section describes the health monitoring features of the X11DPU motherboard. The
motherboard has an onboard Baseboard Management Controller (BMC) chip that supports
system health monitoring. 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.
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. The user
can adjust the voltage thresholds to dene the sensitivity of the voltage monitor. Real time
readings of these voltage levels are all displayed in BIOS.
Fan Status Monitor with Firmware Control
The system health monitor embedded in the BMC chip can check the RPM status of the
cooling fans. The CPU and chassis fans are controlled via lPMI.
Environmental Temperature Control
System Health sensors in the BMC monitor the temperatures and voltage settings of onboard
processors and the system in real time via the IPMI interface. Whenever the temperature of
the CPU or the system exceeds a user-dened threshold, system/CPU cooling fans will be
turned on to prevent the CPU or the system from overheating.
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 used with SuperDoctor 5
®
. SuperDoctor 5 is used to notify the
user of certain system events. For example, you can congure SuperDoctor 5 to provide you
with warnings when the system temperature, CPU temperatures, voltages and fan speeds
go beyond a predened range.
1.4 ACPI Features
ACPI stands for Advanced Conguration and Power Interface. The ACPI specication denes
a exible and abstract hardware interface that provides a standard way to integrate power
management features throughout a computer system including its hardware, operating system
and application software. This enables the system to automatically turn on and off peripherals
such as network cards, hard disk drives and printers.
