I've always been told that the card slots in the non VXR 7206s were not hot swappable. I've got a non VXR 7206 with 1 AC and 1 DC power supply. The DC needs to come out and an AC stuck back in it's place because it's new home does not have DC power available. Can you hot swap the power supply in the non VXR 7200s? -Richey
