Hello Shawn, Thank you so much for your help. I was able to upgrade controller A to GL225P002-02. Plugging in controller B this morning (more than 4 hours ago) stops MC working properly. GUI: "WarningThe system is currently unavailable", CLI: "Error: The MC is not ready. Wait a few seconds then retry the request. (2020-02-10 12:19:34)". Is controller B dead? Is there something like hard reset? Do I have to replace this controller? Many Thanks! Roland
