Re: Power Problem
That really sucks.
OK, now that we've got that out of the way, this doesn't sound right at all. Your rp3440 documentation should tell you what the maximum draw is and the UPS documentation should tell you what it is capable of providing. Unless the rp3440 is drawing more than it should or the UPS is providing less than it should, you should be OK.
The only thing I can think of to check is to make sure that the rp3440 is the only thing plugged into this UPS. If there is something else then you'll need to take the additional equipment's power requirements into account too. If everything seems to add up and supply exceeds demand and the UPS is still tripping (bad acid?? sorry, couldn't resist) then you're going to need to get an electrician in to analyze what is going on because you've got a potentially dangerous, unsafe situation.

Re: Power Problem
I did not do the specs on the UPS, but was told it 'should' handle the load. I guess what you are saying is that it's not the server, but the UPS that is not right. (I didn't think it was the server, either.)
I'll go do my own calculations.
thanks!

Re: Power Problem
The rp3440 has a maximum current requirement of 3.6A shared across both inputs at 230V, figure close to 8A at 110V. The theoretical maximum power dissipation is 1,350 Watts.
What is the make and model of your UPS? What other devices do you have plugged into it?
When you say the UPS "trips", I assume you mean that it is tripping it's input breaker, is this correct? (It's also possible that you could be "tripping" it into battery mode.)
