  Personally I don't like them. All they really do is cover you in case of a power supply failure - they just don't work that well for any other type of failure (UPS, circuit, etc). If you are looking dual power supply functionality (covering UPS failure, someone kicking a power cord out, etc) you have to actually get a dual power supply router or switch. 

  Example, switching BACK to AC once power is restored seems to require the switch/router to reload anyway. If the power supply fails and you are replacing the switch, no big deal. If you lost power for some other reason and it flipped to the RPS for DC power, now you have to reboot the switch and get it back onto AC and off of the RPS before the RPS can protect another device.

    Anyone use these things? I'm spec'ing out either a 3825 or a 3845 - the 3825 should do, just need to be sure the RPS units are robust.
