The ICX7250 I found seem to only have 8x1gbe SFP or 2x10gbe SFP+.
So there's two basic types of 7250; there's the 24G/48G (the G is the important part) that has four total SFP ports that are 1-gig only ports.
The other type is the ones with 8 SFP+ ports. If you're seeing them listed as 8x1GbE, that's because they don't have their licenses enabled. However, with the current firmwares (see Fohdeesha's megathread in here - there's details on the first page including links to downloads, or you can get them direct from Ruckus with a free account) all that is required is to issue a command to enable the 10G functionality on the ports. It's an honor-based system, and as long as you're using it for personal use I sincerely doubt they'll care.
Which of course would mean don't pay extra for the 2x10GbE versions, as you can convert all of those "gigabit" ports to 10G SFP+ with a command.
