I bet the engineers who designed this switch were having a heated debate. 'Let's give it two power inputs, that'll be fancy!' 'But what if someone tries to use them both at once? Chaos!'

C sounds like the most boring option. Where's the fun in only being able to use one input?

A has to be wrong, there's no way the power budget is just the sum of both inputs. That would be too easy!

I was going to say D, but that doesn't sound right. Daisy-chaining power inputs? That seems like a weird design choice.

Yeah, daisy-chaining power inputs does seem like an odd choice. A seems like the safer bet.

I was also considering D, but now I see why A makes more sense.

I think the correct answer is A. Both inputs are connected, and the power budget is the sum of both power inputs.

I think the correct answer is B. That's the only one that makes sense - using one input as primary and the other as backup.

Yes, you're right. That's how the power inputs labeled A and B of IE3400 are used.
