Do I need to use a crossover cable or straight-through cable?
With most switches/routers, the Ethernet ports are Auto MDI-II/MDI-X. This means the port will auto-sense the cable type. Auto
MDI-II/MDI-X ports may react differently if the Ethernet cable is not properly pinned. If you make your own cables, it is very
important that they follow the industry standard pin-out (568A and 568B).
Computer connections to a switch or router typically use a straight-through cable. When connecting a computer to another
computer or to an uplink port then a cross-over cable is typically required. Rule of Thumb: "If there is a link light, the cable is
right. "
How do I verify that my DUB-E100 is properly installed?
