TRENDnet TEG-S081FMI - Manual (Page 10)

You can use the TEG-S081FMi Switch to connect PCs, workstations, and
servers to each other by connecting these devices directly to the Switch.
All the devices in this network can communicate with each other.
Connecting servers to the backbone switch allow other users to access
the server’s data.
The Switch automatically learns node address, which are subsequently
used to filter and forward all traffic based on the destination address. You
can use any of the Fiber port of the Fiber Management Switch to connect
with another Switch or Hub to interconnect each of your small switched
workgroups to form a larger and long distance switched network.
