HPE Aruba CX 6405 Overview

Enterprise campus networks must support growing user populations, high-density wireless deployments, and bandwidth-intensive applications while maintaining reliable connectivity across distributed environments.

Modular Switching for Campus Core and Aggregation

The HPE Aruba CX 6405 v2 Switch is a modular campus switching platform designed for enterprise core and aggregation roles. Built on the AOS-CX operating system, the chassis supports line cards delivering 1GbE, 10GbE, 25GbE, 40GbE, and 100GbE connectivity with high switching capacity and redundant system components. High-speed uplinks, programmable switching, and integrated analytics improve visibility across the access, aggregation, or data-centre fabric, helping teams spot congestion and policy issues before they affect users or applications.

Programmable Architecture with Real-Time Network Telemetry

The CX 6405 v2 integrates the Network Analytics Engine (NAE), enabling continuous monitoring and automated analysis of network traffic and system performance. This programmable architecture allows operators to detect anomalies and automate policy enforcement across campus networks. Organisations that require more chassis slots and line-card capacity may also consider the HPE Aruba CX 6410 v2 Switch, for supporting larger access, aggregation and core builds in one platform.

Scalable Infrastructure for Evolving Campus Networks

With modular expansion and integrated automation capabilities, the CX 6405 v2 allows organisations to scale campus infrastructure while maintaining operational visibility and consistent network performance.

Our specialists can help design and deploy HPE Aruba CX 6405 v2 Switch solutions aligned to your campus network architecture.

HPE Aruba CX 6405 Deployment Scenarios

 

The HPE Aruba CX 6405 v2 Switch is designed for organisations that need a modular switch for campus aggregation, core, and services-edge roles. It suits enterprise networks that need flexible port combinations, high availability, and room to scale without moving to a larger chassis than the site requires.

Campus Aggregation

The Aruba CX 6405 v2 is well suited to campus aggregation layers where multiple access switches, wireless services, and user segments need to be brought together on one modular platform. It supports scalable aggregation with flexible interface options and strong Layer 3 capability.

Collapsed Core Designs

Many midsize campuses use a collapsed core design where routing, aggregation, and policy services sit in one switching layer. The Aruba CX 6405 v2 fits these environments by combining modular growth, resiliency, and high-speed uplinks in a compact chassis.

High-Density Multi-Gig Access Services

Sites supporting Wi-Fi, IoT, and user access often need multi-gigabit ports, PoE, and policy enforcement at scale. The Aruba CX 6405 v2 supports these deployments with modular Smart Rate, PoE, and dynamic segmentation options.

Enterprise Edge and Services Distribution

The Aruba CX 6405 v2 also suits enterprise edge designs where traffic from users, devices, and wireless infrastructure needs to be distributed securely across campus buildings. It supports these roles with high-speed switching and campus-ready policy control.

Private Data Environments

Private data environments and enterprise server rooms can also deploy the Aruba CX 6405 v2 where modular switching, redundant components, and flexible uplinks are needed. It fits sites that want one chassis for aggregation and core-style functions.
