Description
Product Overview
The Enterasys A2H124-24P is a SecureStack A2 Series managed Ethernet switch designed for high-density copper network connections. It provides 24 × 10/100 Mbps RJ45 PoE ports, two SFP expansion ports, and two 10/100/1000BASE-T ports that can be used either as Gigabit Ethernet interfaces or as stacking connections.
The switch is designed for managed network environments where multiple switches need to operate as a single logical stack. The A2 platform supports Layer 2/Layer 3 switching functions, traffic prioritization, and high-density Ethernet connectivity. Up to eight A2 switches can be connected in a stack using Category 5 or better UTP stacking cables.
Key Features
🔌 24 PoE Ethernet Ports — 24 fixed RJ45 10/100 Mbps copper ports provide network connectivity and PoE capability.
⚡ Power over Ethernet — The A2H124-24P is specifically the PoE version of the A2H124 platform.
🔗 Gigabit Uplink / Stack Ports — Two 1000BASE-T RJ45 interfaces can operate as normal Gigabit Ethernet ports or stack ports.
🌐 SFP Expansion — Two SFP slots support compatible fiber or copper Mini-GBIC/SFP interfaces.
🧱 Stackable Architecture — Multiple A2 switches can be linked into a single stack for centralized management.
📊 Managed Switching — Designed for controlled Ethernet network environments rather than basic unmanaged switching.
🔐 Network Management — Supports advanced management and traffic-control functions associated with the SecureStack A2 platform.

Typical Applications
🏭 Industrial Ethernet Networks
The A2H124-24P can be used as a managed access-layer switch in industrial or facility networks where copper Ethernet connectivity and centralized network management are required.
📹 IP Camera and Access Networks
Its PoE ports can provide both Ethernet connectivity and power to compatible powered devices, reducing the need for separate power cabling.
🏢 Building Automation
The switch is suitable for structured Ethernet networks connecting automation controllers, monitoring equipment, terminals and other network devices.
🔗 Stacked Network Architecture
Multiple A2-series switches can be connected together so the stack can be managed as an integrated network device.
Installation Notes
🔧 Before installation, confirm that the connected devices are compatible with the switch’s PoE voltage and power requirements.
🔧 Use Category 5 or better UTP cable for the stacking connections.
🔧 When used in standalone mode, the two 1000BASE-T stacking interfaces can be configured as standard Ethernet ports.
🔧 If SFP uplinks are required, verify the wavelength, fiber type and supported Mini-GBIC/SFP module before installation.
🔧 For PoE installations, calculate the total power requirement of all connected powered devices before connecting the switch.
🔧 Check the firmware version and existing configuration when replacing a unit in an operating network.
