Fault tolerance

Table 9. Fault condition behavior

Condition Behavior

Power loss  Volatile memory data loss (internal memory)

 Data loss if data being written to non-volatile storage. MCC cannot guarantee

integrity of existing data on storage device. (Note 6)

Unexpected removal of SD card  Data loss if data being written to non-volatile storage. MCC cannot guarantee

integrity of existing data on storage device. (Note 6)

Power on after fault.  Unit restarts with existing configuration.

Note 6: Solid-state memory devices behave differently under fault conditions. MCC cannot guarantee the

integrity of data, both new and existing, in the event of power loss, unexpected media removal or

similar actions.
