1. Product Overview
The Enterasys A4H124-4FX (P0973JN) is a Layer 2 managed industrial Ethernet switch from the A4 Series, designed for reliable, high-performance network connectivity in industrial automation, enterprise, and campus environments. It features 24 x 10/100Base-TX RJ45 ports and 4 x 100Base-FX/1000Base-X SFP fiber ports, supporting flexible copper/fiber media conversion for long-distance and EMI-sensitive deployments. With 17.6 Gbps switching capacity, 9.5 Mpps throughput, 16K MAC address table, and advanced features like VLAN (4096), QoS, LACP, and stacking (up to 8 units), it ensures secure, scalable, and redundant network operations. The switch supports dual AC power inputs, front-panel stacking, and multiple management interfaces (Web UI, CLI, SNMP, Telnet), making it ideal for industrial control systems, manufacturing floors, power plants, and data center edge networks, minimizing downtime and optimizing network efficiency.
