Please contact Digitec (customer service) before you buy it. Mine had 1Gbit, which was the older version.
I don't think Digitec buys "in stock" here and you would certainly get a newer model with 2.5 - but verification is required.
Plus, for you to activate the business edition, they have to send you a token by mail (that was a bit of a hassle with mine, but it worked) - I contacted Digitec at the time and then received the token from Deciso...
Have fun with it :) - I wouldn't give my 750 (although 1Gbit) away again...

When I bought them a year ago, they were only 1GB ports, which is why I had to return them and then bought them directly from Deciso.
I can't say whether this is still the case. If in doubt, I would contact Digitec directly.
