Technical Specifications

Key Features and Capabilities

1. Simplified Access Layer Deployment

The Aruba R9Y03A is optimized for wired access deployments. Its 48 ports of Gigabit Ethernet with PoE+ provide ample connectivity for access points, IP cameras, VoIP phones, and IoT devices. These ports support Class 4 PoE+ (30W per port) with a total PoE budget of 740W, making it a perfect solution for high-density device environments.

2. High-Speed Uplinks

With 4 SFP+ 1/10GbE uplinks, the R9Y03A ensures high-speed, low-latency connections to the aggregation/core layer or directly to servers. These uplinks are critical for reducing bottlenecks and enhancing overall network throughput.

3. AOS-CX Operating System

The R9Y03A runs on Aruba’s AOS-CX, a modern, cloud-native operating system that brings consistent management, advanced analytics, and enhanced automation to access switches. AOS-CX provides a robust CLI, a programmable REST API, and an intuitive Web UI, allowing IT teams to manage the switch easily through their preferred method.

Benefits of AOS-CX include:

• Modular architecture for better software stability

• Real-time and historical network state information

• Consistent configuration and monitoring across Aruba switches

• Automation and orchestration capabilities for simplified operations

4. Cloud-Based Management with Aruba Central

The switch is designed to integrate seamlessly with Aruba Central, HPE’s cloud-native network management platform. Aruba Central enables centralized management, AI-powered insights, and enhanced visibility across the network from a single pane of glass. This is particularly valuable for distributed networks, allowing administrators to manage multiple sites remotely and effectively.

5. Security and Access Control

To protect the network from unauthorized access and threats, the R9Y03A includes robust security features:

• 802.1X Port-Based Network Access Control (NAC)

• MAC Authentication Bypass (MAB)

• RADIUS and TACACS+ support

• Access Control Lists (ACLs)

• Traffic segmentation and filtering

These features ensure that only authorized users and devices can connect to the network, helping to maintain a secure digital environment.

6. Energy Efficient and Silent Operation

The Aruba R9Y03A is ENERGY STAR® certified, supporting energy-efficient Ethernet (EEE) and intelligent power management features. It includes a fixed, quiet cooling system, making it suitable for deployments in open office environments or small IT closets where noise levels matter.

Use Cases

1. Enterprise Access Layer

In large organizations, the R9Y03A switch is ideal for use in the access layer to support endpoints like desktops, phones, printers, and access points. Its PoE+ capabilities make it suitable for powering VoIP phones and wireless APs without the need for additional power adapters.

2. Retail and Branch Offices

Retail locations or remote branch offices can benefit from the R9Y03A’s compact design, quiet operation, and centralized management via Aruba Central. With remote troubleshooting and automation, IT departments can support multiple locations with minimal on-site visits.

3. IoT-Heavy Environments

Facilities deploying a large number of IP cameras, sensors, and other IoT devices can leverage the R9Y03A’s PoE+ ports and enhanced security features. With up to 740W of PoE, it eliminates the need for separate power systems for IoT gear.

4. Education and Healthcare Campuses

Schools, universities, and hospitals benefit from secure, high-speed access. The switch supports multiple VLANs, ACLs, and authentication methods, making it easy to segment and control access for students, staff, guests, and medical devices.

Benefits of Deploying Aruba R9Y03A Switch

✔ Enhanced Network Visibility

With Aruba Central and AOS-CX, IT administrators gain end-to-end visibility into network traffic, device status, and performance metrics. Troubleshooting and optimization become faster and more accurate.

✔ Scalable Design

The switch can be deployed individually or as part of a larger access layer network. The modular software architecture ensures that it can scale with growing business needs.

✔ Operational Simplicity

Aruba’s software-defined approach and centralized cloud management minimize the need for manual configurations and repetitive tasks. Automation, AI insights, and monitoring tools streamline network operations.

✔ Reduced Total Cost of Ownership (TCO)

The R9Y03A offers a cost-effective switching solution with enterprise-grade features. Its energy-efficient design and long hardware lifecycle, backed by a limited lifetime warranty, reduce long-term costs.
