The RG231 provides four 10BASE-T/100BASE-TX RJ-45 ports. These LAN
ports are standard RJ-45 Ethernet network ports that connect directly to
PCs. They can also be connected to an Ethernet switch or hub to support
more users.
All ports support automatic MDI/MDI-X operation, so you can use straight-
through cables for all network connections to PCs or servers, or to other
switches or hubs. Each of these ports support auto-negotiation, so the
optimum transmission mode (half or full duplex), and data rate (10 or
100 Mbps) is selected automatically.
Each RJ-45 port includes a built-in LED indicator. This LED indicator is
described in the following table.
