A2H254-16-RH | Layer 3 Managed Switch

Technical Specifications

Key Features and Advantages

The A2H254-16-RH combines copper and fiber connectivity with non-blocking architecture, delivering wire-speed performance for latency-sensitive applications. Its hardware-based QoS prioritizes voice/video traffic with <50μs port-to-port latency.

Advanced security stack: Implements dynamic port security with automatic violation quarantine. The switch’s SecureFabric technology isolates IoT devices through automated policy-based segmentation, reducing attack surfaces by 60% compared to traditional VLAN setups.

Energy-efficient design: Features EcoMode power savings that reduce idle port consumption by 70%. Dual hot-swappable power supplies with load sharing ensure continuous operation during power fluctuations.

Application Areas

In mid-sized enterprise networks, the A2H254-16-RH serves as a collapsed core switch for converged data/voice systems, supporting Jitter <1ms for unified communications. Its 10G uplinks enable seamless connectivity to storage area networks.

Retail environments utilize its port density for digital signage networks and inventory management systems. The built-in sFlow monitoring supports traffic analysis for loss prevention initiatives.

Transportation hubs leverage the switch’s ruggedized design for CCTV backbones and passenger WiFi systems, with MACsec ensuring encrypted video feeds across distributed facilities.
