Chapter 1: Introduction
1.4b System Health Monitoring (X11SCZ-F)
This section describes the health monitoring features of the X11SCZ-F 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 and IPMI interface.
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. Refer to the below table for
available fan modes to choose the most appropriate one of nominal operation.
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 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.
Figure 1-5. Fan Speed Modes
Fan Mode Description
Full Speed Use this mode to set fan speed at full speed for maximum system cooling
Standard Use this mode to set fan speed for normal system cooling
Heavy I/O Use this mode to set fan speed for higher PCI-E add-on card area cooling
Optimal Use this mode to set fan speed for normal PCI-E add-on card area cooling
PUE2 Use this mode to set fan speed for best power ef ciency and maximum noise reduction
