Keep high-demand access layers moving with the HPE Aruba Networking CX 6400 24p Smart Rate 1G/2.5G/5G/10G Class8 PoE and 4p SFP56 v2 module. This modular Layer 3 switch module brings 24 Smart Rate copper ports and 4 SFP56 uplinks into a chassis-based design, giving infrastructure teams a way to scale port density, uplink bandwidth, and power delivery without redesigning the switching layer. Smart Rate support matters when the access layer has to serve mixed endpoint speeds, Wi-Fi access points, and devices that outgrow 1 GbE. Class 8 PoE adds the power headroom needed for higher-draw edge hardware, while 4 SFP56 uplinks provide a stronger path toward distribution or core layers. The result is a switch module that fits modern campus and enterprise designs where both throughput and power budgets are under pressure. This is the kind of hardware that earns its place in a serious network: modular, dense, and built for teams that want to extend the life of their switching architecture instead of replacing it every refresh cycle.
