We had an issue where a 210 switch was connected to a UPS and its presence suddenly caused an output short and the UPS shut down. It's not a big deal since we didn't need the switch but I would like to know if anyone has ran into a similar issue. I took it apart and I don't see anything wrong. I can confirm it does short out if plugged in. Under the power supply is some oily substance on the pad which seems weird to have?
