Description

A4H254-8F8T: Product Overview
The A4H254-8F8T is a managed Layer 2 Ethernet switch from Enterasys Networks (now part of Extreme Networks). This switch functions as a core networking component, providing reliable and intelligent data transmission between connected devices such as computers, servers, printers, and other network-enabled equipment. It operates at the data link layer (Layer 2) of the OSI model, using MAC addresses to forward traffic efficiently within a local area network (LAN).
The switch is designed for use in environments requiring network segmentation, traffic prioritization, and enhanced security features. Its managed capabilities allow network administrators to configure, monitor, and control the network traffic passing through the switch. This includes setting up Virtual LANs (VLANs) to segment network traffic, implementing Quality of Service (QoS) to prioritize critical data, and configuring security features like port security and access control lists (ACLs). The robust metal enclosure is designed for standard 19-inch rack mounting, making it suitable for wiring closets, server rooms, and light industrial settings.

Core Features & Customer Value
The switch’s primary value is its management capability, which provides control and visibility into network traffic. For network administrators, this allows for the creation of VLANs to separate traffic for security and performance, ensuring that sensitive data is isolated from general traffic. The Quality of Service (QoS) features enable prioritization of time-sensitive traffic like voice over IP (VoIP) or video conferencing, reducing latency and jitter for a better user experience.
The robust security features​ help protect the network from unauthorized access and attacks. Features like 802.1X port-based authentication ensure that only authorized devices can connect to the network. The CLI and web GUI provide flexible management options for both novice and experienced network engineers. The high switching capacity and forwarding rate ensure that the switch can handle high traffic loads without becoming a bottleneck, supporting the demands of modern networks.
Typical Applications
In enterprise office environments, the A4H254-8F8T is deployed in wiring closets to connect end-user devices like desktop computers, IP phones, and wireless access points. The managed features allow IT staff to segment departmental traffic and prioritize voice traffic for clear VoIP calls.
In light industrial or manufacturing settings, this switch can be used to connect PLCs, HMIs, and other control system components on a dedicated network segment, providing reliability and security for operational technology (OT) networks.
