I have a snap-pac-s2 that I just configured two weeks ago. It is set up on my desk in the office. Today, I tried to power it up and it is dead. There are no lights. I hit the reset and still nothing. My power supply is putting out 24 VDC. I hook up another snap-pac-s2 and it is working fine. I have a snap-pac-s2 in the field that I used the same power supply with it. The power supply is an Acopian VTD15-160.
