ehh..sorry I don’t completely understand. Until now I first put the adapter in a powered strip, and then put the connector in the H9 to power it up. To power the H9 down I pulled the connector out of the H9. You mean this is not good?
To power the H9 up, or down, is it best to keep the connector in the H9, and then put the adapter in (or out of) a powered strip?
Or, if I understand what you are saying, second best is to keep everything connected and power it up/down by switching the master power switch (on the strip) down/up.
So what I did until now is not good. That is if I interpret your words correctly. I have to keep the connector in the H9. Which I didn’t do.
