Explanation

When connecting a router to a switch and auto MDI-X is unavailable (meaning the devices cannot automatically configure their transmit/receive pins), you must use a crossover cable if: - Pins 1 & 2 are receivers - Pins 3 & 6 are transmitters This pin configuration implies that both devices are sending and receiving on the same pins, which would cause a conflict unless the pins are crossed. A crossover cable swaps the transmit and receive pairs so that transmitters on one end connect to receivers on the other.
