Temperature / System Monitoring
Temperature and system monitoring aim to reliably protect the computer hardware against damage
caused by overheating. In addition, any unnecessary noise is also prevented by reducing the fan
speed and information is provided about the system status.
The temperature and system monitoring are controlled by an onboard controller.
The following functions are supported:
Temperature Monitoring:
Measurement of the processor and system temperature is done with an onboard temperature
sensor; measurement of the ambient temperature is done with an external temperature sensor.
Fan Monitoring:
Fans that are no longer available; blocked or sticky fans that are detected are operated with a 12 V
pulse voltage. Fans removed while the system is switched off are signalled by the
Event
LED. When
the system is switched on again the BIOS processes the application.
Fan Control:
The four fans are regulated according to temperature.
Sensor Monitoring:
The removal of, or a faulty error within the system, detection is done by a temperature sensor.
Should this happen all fans are monitored by this sensor and run at maximum speed, to achieve the
greatest possible protection of the hardware. When the system is switched on again the BIOS
processes the application.
LAN Connector A 10/100 Mbit
This system board has an Intel 82550PM LAN controller. The LAN controller is equipped with a
3 Kbyte transmission and receiving buffer (FIFO) and supports WOL function through Magic
Packet

.
It is also possible to boot a device without its own boot hard disk via LAN. Here Bootix LAN BootP
and Intel PXE are supported.
The LAN RJ45 connector is equipped with a green and a yellow LED (light emitting diode).
