If it makes sense in your context, I would imagine one interpretation might be that "many UPSs can now BE ACCESSED VIA IP" --- presumably to interrogate them about their status, etc.

But I remain unsure about which particular meaning of IP to choose , which will surely have a significant impact on the exact meaning of 'accessible', and thence, 'sous'

I find it hard to imagine what they\'re getting at here; surely they don\'t mean \"you can buy them over the Internet\"? :-))

I don\'t know enough IT to know if it makes sense to say that they are addressable via IP, though I guess in the light of HB\'s reference, they may be talking about remote control applications, and presumably they might just as well use IP as any other kind of more dedicated protocol.

I think you need to be looking at \'can be accessed\' or even \'can be addressed\', and steer clear of the literal translation of \'accessible\'
