Ethernet interfaceThe RPU provides two 100BASE-TX FE interfaces. For their attributes, refer to the section“RPU”.The RPU2 provides three 10/100/1000 Mbps auto-sensing Ethernet interfaces that eachaccommodate an RJ-45 connector and an SFP module respectively for electrical and opticalconnections.The RPU2 provides three 10/100/1000 Mbps Ethernet interfaces, where two are electrical andone provides both fiber-optic and electrical connectors.When both electrical and optical connections are available, you can use only one at a time. Forthe available SFP options and the interface attributes, refer back to the section “RPU2” in thechapter “Router Overview”.II. Ethernet cable1) Electrical Ethernet interface cableElectrical Ethernet interfaces usually use category 5 twisted-pair cables, as shown in thefollowing figure.Figure 3-6 Ethernet cableEthernet cables fit into the following two categories:z Straight-through cable, at both ends of which, the wires are crimped in the RJ-45connectors in the same sequence. The cable connects different types of devices,such as a terminal device (PC for example) or router to a Hub or LAN switch. Thenetwork cables shipped with the router are standard cables.z Crossover cable, at both ends of which, the wires are crimped in the RJ-45connectors in different sequences. The cable connects the same type of devices,such as PC to PC or PC to router. You can make crossover cables by yourself asneeded.
