A4H124-24FX | Layer 3 Managed Switch

Technical Specifications

Key Features and Advantages

The A4H124-24FX redefines network performance with 10G/40G multi-rate support and 1.44Tbps non-blocking architecture. Its adaptive flow control technology eliminates microburst packet loss through dynamic buffer allocation, achieving 99.9999% traffic integrity in financial trading networks.

A4H124-24FX-3

Data center optimized: Features hitless In-Service Software Upgrades (ISSU) and VXLAN hardware acceleration. The switch’s energy-proportional design reduces power consumption by 45% during off-peak through per-port power scaling.

Advanced telemetry: Built-in sFlow and IPFIX export at line rate enable real-time network anomaly detection. The front-panel LCD provides instant port statistics visualization and automated troubleshooting workflows.

Application Areas

In hyperscale data centers, the A4H124-24FX serves as top-of-rack switch for NVMe-oF storage clusters, delivering consistent <1μs latency for distributed all-flash arrays. Its deep buffer design prevents congestion in east-west traffic patterns.

5G mobile edge computing leverages the switch’s precise timing synchronization (PTP IEEE 1588v2) for fronthaul networks. The 40G QSFP28 ports enable high-density connectivity to radio unit bases.

High-frequency trading systems utilize the cut-through switching mode for ultra-low latency order execution. MACsec-256 encryption ensures secure market data feeds between colocation facilities.
