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 define the sensitivity of the voltage monitor. Real time readings
of these voltage levels are all displayed in BMC.
Fan Status Monitor with Firmware Control
Users can check the RPM status of the cooling fans through the IPMI Web interface. The
chassis fans are controlled by Thermal Management.
Environmental Temperature Control
The thermal control sensor monitors the CPU temperature in real time and will turn on the
thermal control fan whenever the CPU temperature exceeds a user-defined threshold. The
overheat circuitry runs independently from the CPU. Once the thermal sensor detects that
the CPU temperature is too high, it will automatically turn on the thermal fans to prevent the
CPU from overheating. The onboard chassis thermal circuitry can monitor the overall system
temperature and alert the user when the chassis temperature is too high.
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
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.
1.6 ACPI Features
ACPI stands for Advanced Configuration and Power Interface. The ACPI specification
defines a flexible 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, storage drives and printers.
In addition to enabling operating system-directed power management, ACPI also provides a
generic system event mechanism for Plug and Play and an operating system-independent
interface for configuration control. ACPI leverages the Plug and Play BIOS data structures
while providing a processor architecture-independent implementation that is compatible with
Windows 2019 and 2022 operating systems.
