Description

A2H124-24FX: Product Overview
The A2H124-24FX is a managed Layer 2 Ethernet switch from Enterasys Networks (now part of Extreme Networks), designed specifically for fiber optic network infrastructure. This switch serves as a high-density aggregation point in network closets, data centers, and as a distribution switch in larger enterprise networks. Its primary function is to provide reliable, high-speed data transmission over fiber optic cabling, which is essential for covering long distances, mitigating electromagnetic interference (EMI), and ensuring high bandwidth connectivity between switches, servers, and other critical network assets.
The switch operates at the data link layer (Layer 2) of the OSI model, using MAC addresses to intelligently forward traffic. As a managed switch, it offers comprehensive control over the network traffic, allowing administrators to configure Virtual LANs (VLANs) for segmentation, implement Quality of Service (QoS) policies for traffic prioritization, and utilize advanced security features to protect the network. The all-fiber design, using Small Form-factor Pluggable (SFP) transceivers, provides flexibility in choosing the appropriate fiber type (multimode or single-mode) and optic wavelength for various link distances and bandwidth requirements.

Core Features & Customer Value
The switch’s primary value is its high-density fiber connectivity​ and management capability. For network architects, this allows for the creation of a robust and scalable network backbone that can cover long distances (up to kilometers/miles with single-mode optics) and is immune to electrical noise, making it ideal for connecting buildings or noisy industrial environments. The SFP-based design provides investment protection and flexibility, allowing the use of various optic types to meet specific distance and budget requirements without replacing the entire switch.
The comprehensive management and security features​ provide control and visibility into network traffic. Administrators can segment network traffic using VLANs for security and performance, prioritize critical data with QoS, and implement port security to prevent unauthorized access. The high switching capacity and forwarding rate ensure the switch can handle aggregated traffic from multiple access switches without congestion, making it suitable for a distribution or core layer role in a mid-sized network.
Typical Applications
In a campus network environment, the A2H124-24FX acts as a distribution switch, aggregating traffic from multiple access switches (e.g., in different wings of a building) over fiber uplinks and connecting to the network core.
In a data center or server room, it is used as a top-of-rack (ToR) switch, providing high-speed fiber connectivity to servers equipped with fiber network interface cards (NICs), ensuring high-throughput, low-latency access to storage and application resources.
