HPE Aruba CX 5420 S0U63A - 20-Port PoE Module with 4 × 1G/10G SFP+

Overview

The HPE Aruba S0U63A is a modular line card designed for the CX 5420 chassis. It provides 20 ports of 10 M / 100 M / 1 G Ethernet with Class-4 PoE, plus 4 SFP+ ports that support either 1 Gb or 10 Gb uplinks. This line card is built to deliver both power and data in a flexible access-layer setup, ideal for enterprise campus networks.With the CX 5420 chassis, the S0U63A can be deployed in environments that require moderate densities of powered devices like Wi-Fi access points, IP phones, or security cameras. The module uses a Gen-7 ASIC architecture for low-latency performance and integrates fully with the AOS-CX operating system. With support for MACsec (hardware), analytics via Aruba's telemetry engine, and modular power/fan trays in the chassis, it ensures resilient and secure access-layer switching.
