I'm running an EISY with IoX 5.9.1. Last night I attempted to link two new-to-my-system devices. I had a SwitchLinc that was previously paired to a mini remote (direct, not through PLM). When presented with the 3 radio buttons to choose how to deal with link, I switched to the last option which said something about retaining previous links. I'm para-phasing as I can't get to that screen at the moment. I got an error message below.

AI results suggested (keep your commentary about AI to yourself, please) that I power cycle the PLM, which I did with the admin console cleanly closed.

I returned to the console and attempted again, this kicked off the normal linking progress bar which takes a few minutes to complete, but then it reset to zero and started again. My console has been in this cycle for over 12 hours and there are no additional indicators whether this will ever finish. I've got probably over 50 devices in my Insteon network and nearly as many scenes. Am I just seeing a complete scan of every device and scene relinking? At this point I'm just going to let this run the rest of the weekend and cross my fingers that it finishes without error.

My concerns are two-fold: one that none of my scenes or programs are runnable due to all the link activity currently running, and two that I'm going to come back to my PC to find that something is irreversibly broken requiring significant rework.

If you have any solid advice or experience to share on this, I would be appreciative.

Rebooting the eisy will usually resolve this issue. You might need to redo the module linking. Check first.

The last (bottom) option is usually to remove existing links. If you cannot successfully link it to your eisy, you might need to factory reset the switch first. In that case, also recreate the direct link with the mini controller, though I'd use a scene would be better.
