The SSA-T1068-0652 and SSA-T1068-0652A have forty-eight 10/100/1000BASE-T RJ45 ports and four 10GBASE-X SFP+ ports, as shown in SSA-T1068-0652 and SSA-T1068-0652A Front Panel.
1 = 10/100/1000BASE-T RJ45 ports | 5 = Micro-USB debug port |
2 = 10GBASE-X SFP+ ports | 6 = OFFLINE/RESTART button |
3 = PoE mode button | 7 = COM port |
4 = System LEDs |
Each of the 10/100/1000BASE-T ports, which support PoE (IEEE 802.3af and 802.3at), can operate in either half-duplex or full-duplex mode which can be determined by either auto-negotiation or manual configuration. The SSA-T1068-0652 and SSA-T1068-0652A can provide PoE power for powered devices on all 48 RJ45 ports simultaneously.
The SFP+ ports support a number of SFP+ pluggable transceivers. For more information about the transceivers, see http://www.extremenetworks.com/product/transceivers/.
