Multispeed backbone switching

You can use the switch as a multispeed backbone switch in a network that serves network
components such as high-speed servers, high-speed storage platforms, and 1G and
2.5G computers. The switch supports speeds from 100 Mbps all the way up to optional
purchased 10G fiber transceivers.
In the following figure, the speed icons indicate the speed of each connection. The
yellow Ethernet cable indicates the uplink connection through a purchased 10G fiber
transceiver to a 10G network router and a 10G Internet connection.
