A4H124-24TX P0973JM ENTERASYS Function and Features
The A4H124-24TX P0973JM is a 24-port Fast Ethernet managed switch module belonging to the Enterasys A4 series, specially engineered for reliable enterprise edge and access-layer network deployments.
It features 24×10/100BASE-TX RJ45 copper ports, supporting speed and duplex auto-negotiation as well as auto MDI/MDIX crossover to simplify cable connections.
It adopts a non-blocking wire-speed switching architecture, delivering full line-rate packet forwarding on all ports without performance degradation under full load.
It supports IEEE 802.1Q VLAN tagging and Q-in-Q double VLAN, enabling flexible network segmentation and service isolation for multi-tenant or multi-department environments.
It provides robust QoS capabilities compliant with IEEE 802.1p and DiffServ standards, with multiple priority queues to schedule voice, video and data traffic separately and guarantee critical service bandwidth.
It comes with comprehensive security functions, including 802.1X port-based authentication, RADIUS and TACACS+ authentication, ACL access filtering, and DHCP snooping to defend against malicious network attacks.
It supports STP and RSTP spanning tree protocols to eliminate Layer 2 network loops and enhance network redundancy and stability.
It offers diverse management options: CLI console, SNMPv3, and web-based management interface. It is fully compatible with the Enterasys NetSight policy management platform for centralized policy deployment and monitoring.
It supports stackable deployment; up to 8 modules can be stacked together to expand port density and achieve unified configuration and management.
It is equipped with 2 Gigabit SFP uplink ports, which can accept fiber or copper SFP transceivers to establish high-bandwidth uplink connections to core switches or aggregation switches.
This is a hot-swappable module, allowing replacement and maintenance inside the chassis without powering down the whole system, minimizing network downtime during upgrades or troubleshooting.
The MAC address table supports up to 8000 MAC entries to accommodate a large number of connected end devices.
It operates in store-and-forward switching mode to perform complete error checking of each frame before forwarding, reducing bad frame propagation across the network.
It is well suited for connecting office workstations, network printers, IP phones, surveillance cameras and video terminals within enterprise local area networks.
Enterprise office access layer: It connects office workstations, VoIP phones, network printers and wireless access points. It supports VLAN segmentation, port-based identity authentication and priority scheduling for voice traffic to guarantee smooth daily office communications.
Campus network access: Installed in wiring closets of classrooms, dormitories and teaching buildings. It enables user access control and stack deployment to support mass terminal connections for large campus networks.
Retail and hotel network access: Used for front-end workstations, POS terminals, guest room network outlets and surveillance cameras. It helps configure access permissions and logically separate guest Wi-Fi networks from internal business networks.
Auxiliary industrial network access: Interfaces with HMIs, PLCs, field sensors and monitoring devices in factories, water treatment plants, power facilities and metallurgy sites. It delivers stable Fast Ethernet transmission for non-latency-critical industrial control and monitoring data.
Government and public institution edge networks: Satisfies strict requirements for 802.1X authentication, ACL filtering and centralized policy management. It is ideal for terminal access in administrative offices and service halls.
Building integrated low-voltage systems: Aggregates low-bandwidth smart devices including indoor surveillance cameras, access control panels and alarm units. The Gigabit SFP uplink ports provide reliable uplink connectivity toward core switches.
