A network element includes a plurality of Input/Output Cards (IOCs), a plurality of Datapath Service Cards (DSCs); and at least one crosspoint switch card (XPC) configured to be able to selectively interconnect each of the IOCs with each of the DSCs. Enabling full interconnectivity between all the IOCs and DSCs enables greater sparing options within the network element. Additionally, network element is configured to enable the XPCs to be spared, thus eliminating the XPCs as a potential single source of failure in the network element.
