Special Features
Recovery from AC Power Loss
The Basic I/O System (BIOS) provides a setting that determines 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 the power-on state. See
the Advanced BIOS Setup section for this setting. The default setting is Last State.

System Health Monitoring
This section describes the features of system health monitoring of the motherboard.
This motherboard has an onboard baseboard management controller (BMC) that
supports system health monitoring. An onboard voltage monitor will scan the follow-
ing onboard voltages continuously: +3.3V, 3.3V Standby, +5V, +5V Standby, +12V,
CPU core, memory, chipset, BMC, and battery voltages. Once a voltage becomes
unstable, a warning or error message is given. The user can adjust the voltage
thresholds inside the BMC Web GUI to define the sensitivity of the voltage monitor.
Fan Status Monitor with Firmware Control
System health monitoring support provided by the BMC controller can check the
RPM status of a cooling fan. The onboard CPU and chassis fans are controlled by
IPMI Thermal Management.
Environmental Temperature Control
The system health sensors monitor temperatures and voltage settings of onboard
processors and the system in real time via the IPMI interface. Whenever the tem-
perature 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 airflow 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 configure
SuperDoctor 5 to provide you with warnings when the system temperature, CPU
temperatures, voltages, and fan speeds go beyond a predefined range.
