Recently removed from a business during an upgrade. I have no power cords or anything close to the voltages that I could try to power them without damaging them, so they have not been tested. They were powered and on during removal but the power cords were damaged during their removal. 4 units in total in this listing, free shipping. Each unit has the ethernet plug units. I only have what you can see. I do not know if all the stands fit the units, but I will include them, they all came from the same location.
