Step 2. Connect one end of a Small Form-Factor Pluggable (SFP) into the SFP+, XG3, or
XG4 port of your switch.
Note: In this example, the cable is connected to XG3 port of the switch. It is also possible to
stack switches using conventional Ethernet cables on the XG1 and XG2 ports. Performance
offered is similar at short ranges, however for cable runs longer than 100 meters, SFP
provides less latency and greater reliability.
