• PCM600• LHMI• WHMIThe 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 isused with the front port.The speed of the front connector interface is limited to 10 Mbps.13.4.2 Ethernet rear connectionsThe Ethernet station bus communication module is provided with either galvanic RJ-45connection or optical multimode LC type connection, depending on the product variantand the selected communication interface option. A shielded twisted-pair cable CAT 5e isused with the RJ-45 connector and an optical multi-mode cable (≤2 km) with the LC typeconnector.In addition, communication modules with multiple Ethernet connectors enable theforwarding of Ethernet traffic. These variants include an internal Ethernet switch thathandles the Ethernet traffic between an protection relay and a station bus. In this case, theused 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 treeprotocol. In daisy-chain type of topology, the network is bus type and it is either withoutswitches, where the station bus starts from the station client, or with a switch to connectsome devices and the protection relays of this product series to the same network.InternalEthernet switch MAC table size is 512 entries. All Ethernet ports share this one commonMAC table.Communication modules including Ethernet connectors X1, X2, and X3 can utilize thethird port for connecting any other device (for example, an SNTP server, that is visible forthe whole local subnet) to a station bus. In RED615, the first Ethernet port X16 isdedicated to the line differential communication and it cannot be used for station buscommunication.The protection relay's default IP address through rear Ethernet port is 192.168.2.10 withthe TCP/IP protocol. The data transfer rate is 10 or 100 Mbps full duplex.1MAC059074-MB A Section 13Protection relay's physical connections615 series ANSI 1143Technical Manual
