Wiping clean a JACE (clean dist)

At times it may be necessary to restore the JACE controller to a known good “empty” state, either to recommission with the current Niagara release build, or else before recommissioning with an earlier Niagara build. To do this , you can install a Niagara “clean dist” (distribution) file.

Wiping clean a JACE is typically unneccessary if upgrading an operational N4 controller to a later Niagara software build—simply using the Commissioning Wizard should be all that is necessary. However, if downgrading a JACE to an earlier release build, install a clean dist file first, to avoid compatibility problems. This applies especially to JACE controllers, as binaries for the (QNX) OS are included in dist files.

NOTE: A conversion (clean) dist file is available to downgrade N4 JACE-8000 controllers to run AX-3.8U1. A requirement for this is adding the JACE-8000-AX license feature to the JACE-8000 license.
