Abstract: In one example in accordance with the present disclosure, a system for auto-negotiation over extended backplane includes an enclosure and a switch external to the enclosure. The enclosure has a NIC (network interface controller) for a server in the enclosure and a DEM (downlink extension module). The DEM has a single DEM PHY connected to the NIC via a backplane and also connected to the switch via an external connection. The DEM PHY facilitates auto-negotiation between the switch and the NIC.

Abstract: One embodiment describes a network system. The system includes a primary enclosure including a network switch system that includes a plurality of physical interface ports. A first one of the plurality of physical interface ports is to communicatively couple to a network. The system further includes a sub-enclosure comprising a network interface card (NIC) to which a computer system is communicatively coupled and a downlink extension module (DEM) that is communicatively coupled with the NIC and a second one of the plurality of physical interface ports of the network switch system to provide network connectivity of the computer system to the network via the network switch system.
