I have dp34 with 2 vs, there were posts about the vs are able to power up the switch, but in my case, it did not, not even with 2 vs, so I have to get a d pro adapter to give more juice to the switch.
if you are talking about those 4X1 diseq, and you have only one box, I think you should be ok, but if you have more than one, than you will need to put the switch back.
