Comment 3 for bug 1381000

I think this approach is overkill.

Let's make it so that the UI has a second stage (can be JS) where you need to test the parameters entered before allowing the edit node form to be saved. All of the infrastructure is already in place to do this because we have the "test power" button on the main node page.

The API can also do a power check when editing a node power parameter (or adding a node that has power defined).
