1.1.2  System Health Monitor Functions

The system board is capable of monitoring the following “system

health” conditions.

• Monitors processor/system temperature and processor overheat

alarm

• Monitors 1.5V/3.3V/±5V/±12V/VCORE voltages and failure

alarm

• Monitors processor/chassis fan speed and failure alarm

• Automatic processor/chassis fan control

• Read back capability that displays accurate temperature, voltage

and fan speed

1.1.3  Intelligence

Automatic CPU/Chassis Fan Off

The CPU and chassis fans will automatically turn off once the system

enters the Suspend mode.

Dual Function Power Button

Depending on the setting in the BIOS setup, this switch will allow

the system to enter the Soft-Off or Suspend mode.

External Modem Ring-on

The Modem Ring-on feature allows the system that is in the

Suspend mode or Soft Power Off mode to wake-up/power-on to

respond to incoming calls.

Note:

This feature supports external modem only.

RTC Timer to Power-on the System

The RTC installed on the system board allows your system to

automatically power-on on the set date and time.
