If I may please share a story from my past...

So, one day I get called into the machine room of a telecoms startup I was involved with. There's that awful "magic blue smoke" smell in the air...

Turns out my boss and one of the other techs had tried to power up our very expensive new "Class 4/5 Softswitch". Unfortunately, they had plugged in all the modules, and had also forgotten that in "Server Space" "48 vold DC" is actually -48... They hadn't even bothered to use a volt-meter during the commissioning...

I think that was something like a $100,000 mistake...
