How to generate a platform reset token for a JACE 8000

Jace 8000’s implement security features that prevent unauthorised access to the Platform and Station. The platform is protected to prevent malicious and unwanted access to the Station it is hosting which means if the credentials are not known or lost etc then there is limited access options available to the end user/engineer. This can occur when a site is taken over or falls under a new maintainer. The only way to securely access the platform is to obtain a platform reset token in return for a key.

If you are not the original installer or owner of the Jace will need to be authorised to obtain a platform reset by submitting a proof of ownership to your Tridium distributor prior to requesting a reset token.

If you are the original installer or owner of the controller then you will not need to prove ownership as the licence will have been issued to you.

All you will need is a Micro USB cable to hand and a Terminal emulator program like PuTTY installed on your PC. Having internet access on the PC you are using will greatly aid this process.

1. Connect the Micro USB cable to the Jace and the PC. Then open the Device Manager in Windows and expand the Com & LPT View then you should expect to see “USB Serial Port (COMxx)”. This is the Jace’s assigned com port that you will use to connect to. Open your terminal emulation software on your PC (For this guide we will refer to the use of PuTTY).

To open the Serial connection to the Jace follow the below:

a) Open Putty, then select, Connection, Serial

b) Configure the serial line with the following settings:

  • Serial Line: COM xx (as stated in Device Manager)
  • Speed (baud): 115200
  • Data bits: 8
  • Stop bits: 1
  • Parity: None
  • Flow control: None

c) In the PuTTY Configuration dialog, click on “Session” and select “Serial” as the “Connection type”.

d) At the login prompt, enter your platform username, and at the password prompt, enter your platform password.

e) From the main menu select option 11 to reboot the device.

f) Watch the output as the device boots and look for the prompt “Press ESC to choose alternate boot options” action this when visible.

g) You will now see the Boot Option Menu where you will want to select option 8 for Reset Platform Credentials. Select Y for yes and hit enter. This will begin the boot to Platform Access Recovery menu. There you will see the Token that will need to be exchanged along with the Host ID to your Tridium distributor. See example below and follow step 2 carefully.

2. Note at this point you will need to stay connected to the controller while completing this process.

a) Copy the information out of the terminal and compile it into an email to your Tridium distributor request a reset token.

c) You should receive a reset token fairly promptly as the token is time sensitive. Once received your code return to the terminal window and select the appropriate key entry option.

d) Once this has been entered you will need to reconnect to the platform using workbench where you will need to enter the default credentials (tridium, niagara). Upon connection you will be prompted to change the default platform credentials.
