Manual Power Failure Recovery
If only the requirement number 1 is met, the saved configuration will be
loaded when the FTB-8500 Series and FTB-8120NGE/8130NGE is manually
started from ToolBox. Thus, the test that was running will be re-created,
configured, and restarted.
Note: For RFC 2544, the configuration will be re-loaded but the test will not
restart automatically.
Note: The power failure recovery is disabled when the SUI terminates normally
or when the test case is cleared.
