NOTE: After recovering factory defaults the initial controller reboot process takes longer than
usual.
On completion, the controller is restored to a factory default state.

Resetting platform credentials
Occasionally a situation will arise where you have a functional JACE-8000 controller but no valid
credentials or system passphrase. This could be due to a change in building ownership or control
contractors. In Niagara 4.4 and later, the Platform Account Recovery feature provides you with a
secure method of regaining access to the JACE-8000 without losing station data and configuration.
Prerequisites:
•
A USB-to-micro USB cable (same cable as that used to connect a smart phone to a computer)
connects the controller to your PC.
•
A terminal emulator (system shell) program, such as PuTTY, is installed on your PC.
•
During the procedure, you will be prompted to provide the hostid and “proof of ownership” for
this controller.
Resetting platform credentials is accomplished via a multi-stage process that involves using serial
shell software plus contacting your Support channel, and interacting with Tridium in order to initiate a
secure method of validating that you (the serial shell user) are authorized to reset the platform
credentials and system passphrase.
NOTE: The controller must be powered off to initiate this procedure. Additionally, you must be able to
communicate with Tridium via phone or email. Also, this process could conceivably take several hours
to complete, depending on your access to cell phone or internet service.
Perform the following steps:
1. Power off the controller.
2. Using the serial shell program on your PC, open a serial connection to the controller.
3. Power up the controller and during the boot sequence, press ESC to enter the recovery mode
which presents alternate boot options.
4. While viewing the Alternate Boot Options menu in the serial shell window, enter 8 to select the
option to “Reset Platform Credentials”, and when prompted to confirm that you intend to reset
platform credentials and system passphrase, enter Y to continue.
The Platform Access Recovery screen displays the controller’s hostId, and OS version, as well as
a randomly generated token and additional instructions, as shown.
