Connect two 10 GbE SFP+ interfaces across a short rack distance with passive twinax direct-attach copper. The fixed SFP+ ends plug directly into compatible ports, creating a copper link without separate optical modules or fiber patch cables. A 2 m reach suits adjacent servers, top-of-rack switches, storage controllers, and other equipment installed within the same cabinet or nearby rack positions. Axiom Memory 487652-B21-2M-AX is an HP-compatible SFP+ to SFP+ passive copper cable. Its direct-attach construction combines the cable and endpoint modules into one assembly, so both ends must be connected to SFP+ cages rather than RJ45 Ethernet ports. Passive DAC assemblies are intended for short interconnects where copper reach, cable routing, and port compatibility match the installation requirement. This specific cable provides a 2 m length for connections that need more routing allowance than a very short patch lead while remaining within the short-distance role of passive direct-attach copper. It is appropriate for 10 GbE links where the equipment accepts HP-compatible SFP+ DACs. Verify port type, host compatibility requirements, and the required cable path before deployment, particularly where switches or servers enforce coded-transceiver support.
