User diagnostic crash via Front Panel Security (FPS) button
Allows the switch’s front panel Clear button to manually initiate a diagnostic reset. In the case of an application hang, this feature allows you to perform reliable diagnostics by debugging via the front panel Clear button. Diagnostic reset is controlled via Front Panel Security (FPS) options.
