The default IP address of the protection relay through this port is 192.168.0.254.
The front port supports TCP/IP protocol. A standard Ethernet CAT 5 crossover cable is
used with the front port.
The speed of the front connector interface is limited to 10 Mbps.

Ethernet rear connections

The Ethernet station bus communication module is provided with either galvanic RJ-45
connection or optical multimode LC type connection, depending on the product variant
and the selected communication interface option. A shielded twisted-pair cable CAT 5e is
used with the RJ-45 connector and an optical multi-mode cable (≤2 km) with the LC type
connector.
In addition, communication modules with multiple Ethernet connectors enable the
forwarding of Ethernet traffic. These variants include an internal Ethernet switch that
handles the Ethernet traffic between an protection relay and a station bus. In this case, the
used network can be a ring or daisy-chain type of network topology. In loop type topology,
a self-healing Ethernet loop is closed by a managed switch supporting rapid spanning tree
protocol. In daisy-chain type of topology, the network is bus type and it is either without
switches, where the station bus starts from the station client, or with a switch to connect
some devices and the protection relays of this product series to the same network.Internal
Ethernet switch MAC table size is 512 entries. All Ethernet ports share this one common
MAC table.
Communication modules including Ethernet connectors X1, X2, and X3 can utilize the
third port for connecting any other device (for example, an SNTP server, that is visible for
the whole local subnet) to a station bus. In RED615, the first Ethernet port X16 is
dedicated to the line differential communication and it cannot be used for station bus
communication.
The protection relay's default IP address through rear Ethernet port is 192.168.2.10 with
the TCP/IP protocol. The data transfer rate is 10 or 100 Mbps full duplex.
