1.4 System Health Monitoring
This section describes the health monitoring features of the A2SDV-4C/8C-LN8F/LN10PF
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.
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. Users can
adjust the voltage thresholds to dene 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. Refer to the below table for
available fan modes to choose the most appropriate one for nominal operation.
Environmental Temperature Control
System Health sensors monitor 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-dened 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 airow to your
system.
System Resource Alert
This feature is available when used with SuperDoctor 5® in the Windows OS or in the Linux
environment. SuperDoctor is used to notify the user of certain system events. For example,
you can congure SuperDoctor to provide you with warnings when the system temperature,
CPU temperatures, voltages and fan speeds go beyond a predened range.
Figure 1-7. 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 effi ciency and maximum noise reduction
