1.4 System Health Monitoring

Onboard Voltage Monitors

An onboard voltage monitor will scan the voltages of the onboard chipset, memory, CPU,
and battery continuously. 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.

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

1.5 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 CD-ROMs, network cards, hard disk 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 2012/2012R and 2016 operating systems.
