HPE S0U55A - Aruba CX 5420 Management Module
Overview
The HPE S0U55A is the primary management module for the Aruba CX 5420 modular chassis. It runs the AOS-CX operating system and handles the control plane for line-cards, enabling Layer-3 routing, CLI/Web access, time-series database analytics, and VSX high-availability when paired with a second module. This module is critical × without it or its standby pair, the CX 5420 chassis cannot operate. It's well-suited for campus access, aggregation, or branch infrastructure, providing the brains for automated, secure, and scalable networking.
Key Features
Full AOS-CX OS × enables advanced Layer-3 routing, ACLs, scripting, REST API, and telemetry.
VSX Live Upgrade support × allows non-disruptive software upgrades when used in a redundant pair.
Gen-7 ASIC architecture support × provides low-latency high-performance control plane.
Redundant control plane capability × supports active/standby setup for high availability.
