I have Delta Electronics RPS-700-2 A power supply (650W). He can work with one segment of 350W, with two, or all three. But if i pull out one of them during operation, psu shut down and orange led's appear instead green, also if i start psu with 2 segments, and push back 3rd segment, psu goes off.

That mean that redundant and hot swap are not working

Any solutions ?
 
Solution
You need the prints or you'll have to figure out on your own how it works. I presume you at least have a scope and a DVM to check it out? Based on the circuitry and the components, can you figure out how the monitoring and switching are done?
