Hello all, we have a dk280 for cabinet setup here at work, seems we somehow lost another power supply.

as for why we have four cabinets, I do not know. we have empty slots in the third cabinet and only one that I know we use in the fourth cabinet...

I found the issue when I went to check on some programming and could not get in then found that 4th power supply to be dead...

I tried the three button reset trick and get a little life out of it, all three lights going to town, blinking on and off and a relay ckicking to all get out right behind those leds...

any suggestions a component check on the board and or any thing else other than flat out replacement of the power supply?

on another note, can I move the programming card out of the bottom fourth cabinet into one of the many empty slots in the third cabinet and if so, will the system need to be powered down to do so?

Thanks
