Tried to access our home network drive and there was no answer. Suspecting a loose network cable or switch that needed a reset, I head into the office and notice right away that the UPS under the office desk is blacked out. Did one of the cats knock the power cord loose?
I jiggle cords, press power buttons, no joy, so I take the UPS out into a open well-lit area so I can check her out. I pull out the batteries, thinking they might not be holding a charge anymore (this UPS is about 6 years old), and this is what I see:
Something toasted inside the unit and left char all inside the unit. Interestingly, there’s no smoky smell, or even that typical scent of “uh oh” ozone that anyone who has every dabbled with electronics will know. Just this gray soot over the inside of the box.
I just replaced it with another unit (is 6 years a long time for a UPS?), but am not wondering if placing it under a flammable desk is the best location for it.
