Features Temperature / system monitoring
3.5 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 the inhouse temperature by an onboard
sensor, measurement of the ambient temperature by a I²C temperature sensor.
Fan monitoring
Fans that are no longer available, blocked or sticky fans are detected.
Fan control
The fans are regulated according to temperature.
Sensor monitoring
The removal of, or a fault in, a temperature sensor is detected. Should this
happen all fans monitored by this sensor run at maximum speed, to achieve the
greatest possible protection of the hardware.
Voltage monitoring
When voltage exceeds warning level high or falls below warning level low an
alert will be generated.
System Event Log (SEL)
All monitored events of the system board are recorded in the System Event Log.
They could be retrieved after a reboot via ServerView.
