The SSA-G1018-0652 has forty-eight 1000BASE-T SFP ports and four 10GBASE-X SFP+ ports, as shown in SSA-T1068-0652A Front Panel.
1 = 1000BASE-T SFP ports | 4 = Micro-USB debug port |
2 = 10GBASE-X SFP+ ports | 5 = OFFLINE/RESTART button |
3 = System LEDs | 6 = COM port |
Each of the 1000BASE-T ports can operate in either half-duplex or full-duplex mode which can be determined by either auto-negotiation or manual configuration.
The SFP and SFP+ ports support a number of SFP and SFP+ pluggable transceivers. For more information about the transceivers, see http://www.extremenetworks.com/product/transceivers/.
