12 Power Failure Recovery
The automatic power failure recovery is used to re-create, configure, and
restart
1
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 automatic 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. Tapping the
FTB-1 power button for 5 seconds performs a power down reset and is
also considered as a power failure condition.
2. The Automatic Power On feature is enabled for this module from Mini
ToolBox. Refer to the Mini ToolBox 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-700G/800 Series is manually started from Mini
ToolBox. Thus, the test that was running will be re-created, configured,
and restarted.
Note: The power failure recovery is disabled when the application (GUI) closes
normally.
1. Not applicable for RFC 2544 Ethernet test application. The RFC 2544 test must be started manually.
