Enter Configuration Mode, enabling access to the Web Console for one hour.
This will restart the Field Agent operating system and Predix machine without affecting the controller.
This will reset the IP Address back to the default, and remove Predix Enrollment information from the
Field Agent. On the first boot following a factory reset, Predix Machine will generate cryptographic keys
used for communication.
It is Critical the Field Agent is not powered down during these operations to prevent corruption that may
require another factory reset to resolve. Please wait until the EFA Status is Not Connected (FAOK LED
blinking at 1Hz) before cycling power.
