Troubleshooting a network that uses single color cross over cable

What faster approach can I use to troubleshoot a network that use single color cross over cable? I need to troubleshoot an Ethernet network that uses one color cross over cable, if I troubleshoot each cable one after the other, the downtime would be much. To mitigate against this, am looking for a better approach that will reduce the downtime.

Troubleshooting a network that uses single color cross over cable

That’s the problem when your network cable is single-colored. An Ethernet cable contains eight color-coded cables inside. Normally, when you buy an Ethernet cable, it is usually a straight through cable unless you specifically asked for a crossover cable. A straight through cable is totally different from a crossover cable. In a straight through cable, all cables go straight to their respective pins in order.

For example, the cable on pin 1 on connector A will go straight to pin 1 on the other end or on connector B. And that goes to pin 2 and so on. But in a crossover cable, pin assignments are different. Pins 1, 2, 3, and 6 are crossed-linked to pins 3, 6, 1, and 2 respectively. Here are the pin assignments for crossover cable:

  • * Pin 1 – the cable connected to pin 1 on connector A should be connected to pin 3 on connector B.
  • * Pin 2 – the cable connected to pin 2 on connector A should be connected to pin 6 on connector B.
  • * Pin 3 – the cable connected to pin 3 on connector A should be connected to pin 1 on connector B.
  • * Pin 4 – this cable should stay as is. It is not cross-linked.
  • * Pin 5 – this cable should stay as is. It is not cross-linked.
  • * Pin 6 – the cable connected to pin 6 on connector A should be connected to pin 2 on connector B.
  • * Pin 7 – this cable should stay as is. It is not cross-linked.
  • * Pin 8 – this cable should stay as is. It is not cross-linked.

You don’t need to actually troubleshoot each cable. Only four cables need to be checked and cross-linked. The other four should remain untouched.
