21 Power Failure Recovery
The automatic power failure recovery is used to re-create and restart the
test that was running before the power failure. A test that was created and
not running before the power failure will be re-created but not started. The
configuration of the test is saved automatically once the test is created. The
logger, injections, and configuration are periodically saved.
The following requirements control the power failure recovery process:
1. The power failure occurred while the test case is created. A power
failure condition occurs when the AC power is down while the unit’s
battery has not sufficient power to keep the unit running.
2. The Application Startup is enabled for this module from ToolBox CE.
Refer to the ToolBox CE user guide for more information.
Automatic Power Failure Recovery
If the requirements number 1 and 2 are met, the saved configuration will
be loaded when the unit is rebooted after a power failure. Thus, the test
that was running will be re-created, configured, and restarted; the test that
was not running will be re-created and configured.
Manual Power Failure Recovery
If only the requirement number 1 is met, the saved configuration will be
loaded when the FTB-8100 Series is manually started from ToolBox CE.
Thus, the test that was running will be re-created, configured, and
restarted.
Note: The power failure recovery is disabled when the GUI terminates normally
or when the test case is cleared.
