Hi, Both of these devices have four shared, in right terms so called "combo SFP ports".
That means, the last four ports 21-24 can either be used as copper or SFP ports, not both (only four instead of eight ports). If you look in our product datasheets or solution guide, if there's stated 2 or 4 SFP Combo ports, they are shared, if it just says 2 or 4 SFP ports (without the term Combo), then the ports are additional ports, to the 24 or 48 ports. B2G/B3G/B5G have SFP combo ports B3K/B5K have SFP/SFP+ additional ports Hope this helps. Cheers, Markus Sent via iPhone.
