FOXBORO A4H124-24TX Managed Ethernet Switch Brand New

FOXBORO A4H124-24TX Managed Ethernet Switch

Enterprise-Grade Performance for Industrial Environments

Overview

The FOXBORO A4H124-24TX is a robust Layer 2 managed Ethernet switch designed to deliver exceptional performance, flexibility, and reliability in both industrial and enterprise networking environments. Originally developed by Enterasys (later acquired by Extreme Networks) and integrated into Foxboro’s industrial control systems like the I/A Series, this model bridges the gap between IT and OT (Operational Technology) requirements.

Being brand new ensures the switch offers optimal lifespan, full feature support, and top-tier reliability for critical infrastructure applications.

Key Features

• 24 × 10/100BASE-TX Copper Ports
  Standard RJ-45 ports for extensive connectivity with controllers, HMIs, sensors, and other Ethernet-enabled devices.

• Flexible Gigabit Uplinks
  Includes:

• 2 × 10/100/1000BASE-T RJ-45 uplink/stacking ports

• 2 × SFP (Mini-GBIC) slots for copper or fiber Gigabit transceivers
  These ports support high-speed connections to the network core or additional switches.

• Advanced Layer 2 Managed Features

• VLAN Support (IEEE 802.1Q): Up to 4096 VLANs for traffic segmentation and improved security.

• QoS (IEEE 802.1p): Prioritizes time-sensitive data (e.g., VoIP, control systems).

• Spanning Tree Protocol (STP/RSTP/MSTP): Enables redundant paths and prevents loops.

• MAC Filtering & 802.1X Authentication: Enhances access control and network security.

• SNMP (v1/v2c/v3), HTTP, Telnet, SSH, CLI: Full remote monitoring and configuration options.

• Stacking Capability
  Stack up to 8 A4-series switches into a single logical unit, providing scalability, increased port density, and simplified administration.

• High Switching Performance

• Switching Capacity: Up to 17.6 Gbps

• Forwarding Rate: ~9.5 Mpps (non-blocking architecture)

• Industrial-Grade Reliability
  Designed to withstand temperature variation, vibration, and EMI — making it ideal for mission-critical environments.

• Redundant Power Supply Support
  Equipped with external RPS connector for uninterrupted power in critical applications.

• Fanless Operation (Model Dependent)
  Quiet design suitable for control rooms and other noise-sensitive environments.

• Jumbo Frame Support
  Handles Ethernet frames up to 9216 or 10K bytes, ideal for high-throughput applications.
