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.
