Keep critical access networks stable with a switch module designed for high-density PoE delivery and disciplined Layer 3 control. The HPE Aruba Networking CX 5420 24G Class 4 PoE Module provides 24 10/100/1000 ports with PoE Class 4 support, making it a strong fit for powering phones, access points, cameras, and other edge devices from a single modular chassis. Built as a plug-in module for the CX 5420 family, it supports front-to-back airflow for predictable rack integration and thermal planning. Managed operation gives network teams the control expected in enterprise environments, while Layer 3 support helps segment traffic and keep access domains clean as deployments scale. This module is aimed at organizations that need more than basic switching. It is designed for environments where uptime, power distribution, and operational consistency matter more than lowest-cost port count. For teams standardizing on Aruba infrastructure, it extends the value of the CX 5420 platform with a compact, serviceable access layer built for demanding networks.
