Issue
Can a JACE-NXT controller that was originally installed with Niagara R2 be cleared and re-installed with Niagara G3 for a site upgrade?
Product Line
TAC IA SeriesEnvironment
- Niagara R2
- Niagara G3
- JACE-NXT
Cause
The site is upgrading from Niagara R2 to Niagara G3, requiring confirmation of compatibility and installation steps for JACE-NXT hardware.
Resolution
Yes, it is possible to reinstall Niagara G3 on a JACE-NXT previously running Niagara R2:
- Connect via Remote Desktop to access the internal Windows desktop of the JACE-NXT.
- Install Niagara G3 as you would on any Windows-based system.
- Check storage type:
- If the JACE-NXT has a hard drive, there is sufficient space for G3 installation.
- If it has a flash drive, space is limited. You may need to completely remove Niagara R2 before copying and installing G3 files.
- Purchase and apply a Niagara G3 license for the unit.
- Note: Tridium does not provide an upgrade service for this process. It is a manual, do-it-yourself task.
