M11SDV-4C/4CT/8C/8CT/8C+-LN4F motherboard. The motherboard has an onboard

System Hardware Monitor chip AST2500 that supports system health monitoring.

Recovery from AC Power Loss

The Basic Input/Ouput 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.

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-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® in the Windows OS or in the Linux

environment. SuperDoctor is used to notify the user of certain system events. For example,

you can congure SuperDoctor to provide you with warnings when the system temperature,

CPU temperatures, voltages and fan speeds go beyond a predened range.

1.4 System Health Monitoring

This section describes the health monitoring features of the M11SDV-4C/4CT/8C/8CT/8C+-LN4F

motherboard. The motherboard has an onboard Baseboard Management Controller (BMC)

chip that supports system health monitoring.

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 dene 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 chip can check the RPM status of a cooling fan. The CPU and

chassis fans are controlled by BIOS Thermal Management through the back panel. Refer

to the below table for available fan modes to choose the most appropriate one for nominal

operation.

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
