The Cisco ME switch supports the SFP module patch cable, a 0.5-meter, copper, passive cable with SFP module connectors at each end. The patch cable connects two Cisco ME switches in a cascaded configuration.
On the Cisco ME-3400-24FS-A switch, only the Gigabit Ethernet uplink ports support the SFP module patch cable.
You can order the SFP module patch cable (part number CAB-SFP-50CM=).
