Using your hub, you can also connect 10Base-T networks and
100Base-TX and 1000Base-SX/LX networks together for more
flexibility in your network topology. As in the Figure 16 shown

to a 10Base-T network, and through another port, connect to a
100Base-TX port, creating one network. This switch can also
connect to a 1000 Base-LX or SX port.
