Server edition "update primary or Consolidate"?

[d00ner62]

What is the cause of, and reason for, My server edition asking me to "reconsolidate or Update Primary?" What is the difference?

I remember once selecting one of the 2 options and it bricked one of my expansion cabinets..

I just do not want to run into the issue again, but also do not know how to recreate the message. I see it here and there but do not know why or when it shows up......

The SE lost communication to one of the expansion units.
You made changes to the SE, so the expansion unit needs to be updated with those changes.

So what are the 2 options? What do they do?

1. reconsolidate?

or

2. Update Primary?

What does each one do?

Which one would I choose to "reinform" the expansion cabinet?

What are the SE options set in Manager?
