Most of my equipment has dual power input, one plugged into UPS and the other into non-ups regular AC power. I like it that way so I can change things around with the UPS and AC power without interruption. Plus sometimes UPS modules fail. Is there a Y dongle or power strip or something that I can take from two AC sources into one plug and fail between the sources?
