I'm looking to use a RPS 2300 to act as a redundant power supply for some 2950 switches in my data center. I figured that they would be able to keep my 4 switches up and running in the event that power was lost to the switches. As long as I have my RPS unit on a different ciruit. What I'm reading is that it will only protect against local power supply failures and can only backup up to 2 devices at one time. So protection from losing power to half of a network rack is not possible. Can anyone either confirm or deny?
