Temperature / system monitoring Features
Sensor monitoring
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
Unauthorized 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
System Event Log (SEL)
All monitored events of the system board are recorded in the System Event Log.
They could be retrieved after a system reboot via ServerView.
