Build a higher-capacity access layer with the HPE Aruba Networking CX 5420 16-port Smart Rate PoE module. Designed for environments where standard Gigabit ports are no longer enough, this module supports 1G, 2.5G, and 5GBase-T connectivity across 16 ports, giving modern wireless access points and high-demand edge devices the bandwidth they need without forcing an immediate uplink redesign. Class 6 PoE support adds the power headroom required for advanced endpoints, reducing the need for external power sources and simplifying cabinet design. Layer 3 management brings routing-aware control into the switching fabric, which is valuable when segmentation, policy, and traffic placement matter at the edge. The front-to-back airflow design aligns with common data center and campus rack cooling patterns, helping maintain predictable thermal behavior in dense installations. As a plug-in module for the CX 5420 platform, it is built for teams that want to scale port density and endpoint capability while staying within a consistent operational model. This is the kind of module that earns its place in networks where access performance, power delivery, and long-term platform fit all matter.
