2.6 Connecting the Router to LAN

2.6.1 Ethernet cable

A 10/100Base-TX Ethernet interface is usually connected to an Ethernet using a category 5 twisted pair cable, as shown in Figure 2-4:

Figure 2-4Ethernet cable assembly

Ethernet cables fit into two categories: straight-through and crossover.

zStraight-through cable, at both ends of which, the wires are crimped in the RJ45 connectors in the same sequence. The cable is used for connecting different types of devices, such as a terminal device (PC for example) or router to a Hub or LAN switch.

zCrossover cable, at both ends of which, the wires are crimped in the RJ 45 connectors in different sequence. The cable is used for connecting the same type of devices, such as PC to PC or PC to router.

Caution:

In preparing network cables, shielded cables are preferred for the sake of electromagnetic compatibility.

2.6.2 Connecting an Ethernet cable

Caution:

Read the mark above the port to be connected carefully before making connection to make sure it is the right port.

The 10/100BASE-T interface on the 3036 series supports MDI/MDIX autosensing. Therefore, you can connect your router to another device using either straight-through cable or crossover cable without considering whether the two devices are of the same type.

You can simply connect one end of the network cable to the Ethernet port on the router and the other end to another device.
