monitoring
• Monitoring of high and low temperature limits and
cable break of the temperature sensors
• For this, temperature sensors record the temperature
at critical points of the device, e.g. at the processor.
• The temperature thresholds are defined for the
individual temperature sensors.
• Status display "TEMP (Page 27)"
• Speed control of the device fans,
the fan of the power supply unit
and the fan of the graphics card
• Temperature alarm is output.
• Monitoring of underspeed and failure of a fan as well
