Temperature / System Monitoring - Fujitsu D1919 Technical Manual

Temperature / system monitoring

Features
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
developed by Fujitsu Siemens.
The following functions are supported:
Temperature monitoring
Measurement of the processor temperature, measurement of the ambient
temperature by a temperature sensor on the LED board.
Fan monitoring
The PWM fans are monitored. 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
Cover monitoring:
Unauthorised opening of the cover is detected, even when the system is
switched off. However, this will only be indicated when the system is switched
on again
