Introduction to the Ethernet interface
The Router 5000 provide fixed 100BASE-TX FE interface(s). For the interface attributes, refer to Table 13.

Ethernet MDI (Media Dependent Interface) is the typical Ethernet interface on ordinary network cards. MDIX is crossover media-dependent interface, which is generally used on Hubs or LAN switches.
Ethernet cable
100BASE-TX Ethernet interface usually uses Category-5 twisted pair as shown in the following figure:
Figure 13 Ethernet cable assembly
■Straight-through cable: The wire sequences of the twisted pair cable crimped by the RJ45 connectors at both ends of the cable are totally the same. It is used to connect the terminal equipment, such as PCs and routers to HUBs or LAN Switches.
■Cross-over cable: The wire sequences of the twisted pair wires crimped by the RJ45 connectors at both ends of the cable are different. It is used to connect the terminal equipment (such as PCs) to the terminal equipment (such as PCs). If needed, the user can make such cables himself.
