Checking and Clearing the MTBF

The ft server manages Mean Time Between Failures (MTBF) of each component. If a fault occurs in a
component, the ft server calculates the MTBF of the component again. If the calculated value is lower than the
defined threshold, the ft server disables the component to be used.
A disabled component with the MTBF lower than the threshold can be forcibly enabled by clearing the MTBF.
