Temperature/system monitoring Features
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 signalized via the Global Error
LED and recorded in the System Event Log. They could be retrieved in the BIOS
Setup or via ServerView.
Diagnostic LEDs
For signalisation of failures LEDs are situated on the system board.
