The HPE R9W92A Aruba Networking 48-Port Layer 3 Switch

The HPE R9W92A Aruba Networking SFP+ 4x40/100G 48-Ports QSFP28 L3 Managed Hot-pluggable Rack-Mountable 1U Switch is engineered to deliver ultra-high bandwidth, low latency, and enterprise-class resiliency for modern data centers and campus core networks. Designed by Hewlett Packard Enterprise (HPE) under its advanced Aruba Networking portfolio, this switch integrates cutting-edge silicon architecture with intelligent Layer 3 routing features to support next-generation workloads, including virtualization, cloud computing, AI-driven analytics, storage networking, and high-performance enterprise applications.

48-Port QSFP28 Architecture

The 48-port QSFP28 configuration is optimized for high-throughput environments where port density and performance are critical. Each QSFP28 port supports 100 Gigabit Ethernet and can be configured for 40G connectivity, enabling versatile deployment options across data center topologies. This density allows enterprises to maximize rack space utilization while maintaining exceptional performance metrics.

Flexible 40G and 100G Ethernet Support

With support for both 40G and 100G Ethernet standards, the switch offers backward compatibility and future-proof scalability. Organizations transitioning from 10G or 40G environments can incrementally upgrade to 100G without replacing their entire networking infrastructure. This adaptability reduces capital expenditures and extends hardware lifecycle value.

QSFP28 and SFP+ Transceiver Compatibility

The switch supports a wide range of optical and direct-attach copper transceivers, including QSFP28 modules for 100G connectivity and SFP+ modules for 10G uplinks. This ensures compatibility with various fiber and copper cabling infrastructures, including single-mode and multi-mode fiber deployments. Enterprises can deploy short-range or long-range optics depending on data center layout and connectivity requirements.

Advanced Layer 3 Managed Switching Capabilities

The HPE R9W92A Aruba Networking switch operates as a fully managed Layer 3 device, providing intelligent routing, segmentation, and traffic optimization across enterprise networks. Advanced Layer 3 features allow organizations to build scalable and resilient routing domains with dynamic and static routing protocols.

Dynamic Routing Protocol Support

Layer 3 functionality includes support for routing protocols that enhance network efficiency and redundancy. These capabilities allow automatic route recalculation in the event of link failures, ensuring uninterrupted data flow across the network fabric. This makes the switch suitable for core, aggregation, and spine roles within distributed network architectures.

Enhanced Network Segmentation and Security

Through VLAN support, access control mechanisms, and policy-based routing, the switch enables granular traffic segmentation. Network administrators can isolate departments, tenants, or application tiers to improve security and optimize bandwidth utilization. Integrated security features help mitigate internal threats while maintaining high-speed connectivity.

Hot-Pluggable and Modular Design

The hot-pluggable architecture of the HPE R9W92A switch enables seamless replacement or upgrade of components without powering down the system. This design minimizes downtime and enhances operational continuity in mission-critical environments.

Hot-Swappable Power Supplies

Redundant, hot-swappable power supply units ensure continuous operation even in the event of a hardware failure. This redundancy is essential for data centers and enterprise core networks where uptime is paramount.

1U Rack-Mountable Form Factor

The compact 1U rack-mountable design maximizes rack efficiency while delivering high port density. This makes the switch suitable for environments where space is limited but performance requirements are substantial. The standardized form factor allows easy integration into existing server racks and network cabinets..

Comprehensive Network Management

As part of the Aruba Networking ecosystem, the HPE R9W92A switch integrates with centralized management platforms, offering visibility and control over the entire network infrastructure. Administrators benefit from streamlined configuration, monitoring, and troubleshooting capabilities.

Optimized Thermal Management

Advanced airflow engineering ensures consistent cooling across all components, preventing thermal hotspots and extending hardware lifespan.
