3. Making Network Connections
3.1 Network Switched Ports
The following figure illustrates the switched ports provided on the front panel. The switch comes with 24
10/100BASE-TX Fast Ethernet switched ports and two Gigabit Ethernet slots for Gigabit Ethernet modules.
The following table lists the connectors provided on each network ports:

10/100BASE-TX Fast Ethernet Switched Ports
Each switched port supports one connection to a LAN segments. Each segment is an independent shared
network in one collision-domain. The connection can be to either a 10BASE-T or a 100BASE-TX device.

MDI-X and MDI RJ-45 Connectors
MDI-X jack is labeled [X] normally to indicate the jack is designed with internal crossover function. It
allows a connection to an end station using straight-through UTP cable. MDI RJ-45 connector is provided
on port for easy uplink via standard straight-through UTP to other device that supports MDI-X RJ-45
connector. The following table shows the pin assignments of MDI-X and MDI RJ-45 connector respec-
tively:
