1.4 System Health Monitoring

This section describes the health monitoring features of the X11DDW-L/NT 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 define 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 define 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-defined 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-
flow to your system.

System Resource Alert

This feature is available when used with SuperDoctor 5
user of certain system events. For example, you can configure SuperDoctor 5 to provide you
with warnings when the system temperature, CPU temperatures, voltages and fan speeds
go beyond a predefined range.
. SuperDoctor 5 is used to notify the
