Crossover Cables
Intel® Ethernet Converged Network Adapters X540 Series and network connections based on the Intel® Ethernet Controller X540 Series use Automatic MDI/MDI-X Configuration. Intel recommends using straight through cables. Where crossover cables are used, all four pairs must be crossed. Using crossover cables where only some pairs are crossed is not supported and might result in link failure or slow links.

This applies to:

Intel® Ethernet Controller X540-AT2
Intel® Ethernet Converged Network Adapter X540-T1
Intel® Ethernet Converged Network Adapter X540-T2
