Defect Severity 2

8.8.3
Faults of defect severity 2 are fatal device faults that lead to an immediate restart of the device (reset).
This occurs when the device data is corrupted (for example, RAM memory), if a restart prevents restoration of
data consistency. The device goes briefly out of operation, a failure is avoided.

If the fault of defect severity 2 has not be been removed after 3 unsuccessful restarts (reset), the fault is
automatically assigned to defect severity 3. The device will automatically turn to the fallback mode.
