21Ethernet cableEthernet interfaces usually use category 5 twisted pair cables, as shown in the following figure:Figure 14 Ethernet cableEthernet cables fit into the following two categories:• Standard cable, also called straight-through cable, at both ends of which, wires are crimped in theRJ-45 connectors in the same sequence. The cable connects different categories of devices, such asa terminal device (PC for example) or router to a Hub or LAN switch. The cable accompanying therouter is standard cable.• Crossover cable, at both ends of which, wires are crimped in the RJ-45 connectors in differentsequences. The cable connects the same category of devices, such as PC to PC or PC to router. Youcan make crossover cables yourself as needed.NOTE:In making network cables, shielded cables are preferred for electromagnetic compatibility sake.Connecting the Ethernet cableFollow the steps below to connect an Ethernet cable:Step1 Connect one end of the Ethernet cable to an Ethernet port on the router and the other end to anotherdevice.• For a 10/100 Mbps port provided by the RPU, connect it to a PC or another router using a crossovercable or to a Hub or LAN switch using a straight-through cable.Step2 View the LINK LED of the Ethernet interface: ON means a link is present. OFF means no link is present;check the line for the cause.Ethernet Switching InterfaceThe MSR 20-21 Router is available with fixed 100Base-TX FE interface(s).
