Its like this. Im moving out of the house, and I live in a horrible stupid little island. Called Terceira, and placed in Azores. (Good luck finding it on Google Map ). So, im moving out of the house for a couple of weeks, and I want my server to be on all the time. The problem is that electricity fails allot in here, and sometimes, more that 2 hours, so ... If I had 1 UPS - to Another UPS - to another UPS When the power failed, and then batteryof the UPS failed, it would go to the second UPS, etc .. The problem with this situation is that, because the UPS doesnt automaticly turn himself on (the #1 UPS in this case) the other one (#2) would never have power again, and the same thing with #3. I dont know if I mafe myself clear, but if not, ill try to expain a little bit better next time. Thanks all
