Hi Silvan: Hope you are doing well. It looks like there is only one model of these switches that supports SFP on the 100mbit ports. That model is ME 3400-24FS. It supports SFP on the 100mbit ports and on the 2 gbit uplink ports. The other switch from this platform that has only 10/100mbit ports (ME 3400-24TS) only supports SFP on the 2 gigabit uplink ports. The remainder of the switches in this series: ME 3400G-12CS ME 3400G-2CS Both have 24 10/100/1000 Dual purpose ports that support SFP and RJ45. I hope this helps.
