The ENTERASYS A2H254-16 P0973BK is built to thrive in industrial environments where reliability and performance are non-negotiable. Its wide temperature range (-40°C to 75°C) and shock/vibration resistance (compliant with IEC 61373) make it suitable for deployment in harsh settings like factory floors, outdoor substations, or moving vehicles (e.g., trains). The switch supports dual power inputs (AC/DC options), ensuring redundancy and preventing downtime due to power failures.
From a networking perspective, the switch excels in Layer 3 routing, enabling efficient data flow between different subnets and reducing reliance on separate routers. Its QoS capabilities prioritize time-sensitive traffic like real-time control signals or video surveillance, ensuring critical data is transmitted without delay. The P0973BK power supply delivers stable power with surge protection, further enhancing reliability in unstable electrical environments.
Security is a core focus, with features like port-based authentication (802.1X), access control lists (ACLs), and encrypted management interfaces (SNMPv3, HTTPS) safeguarding against unauthorized access and cyber attacks. This is particularly vital in industrial sectors where network security is regulated by standards like NERC CIP or IEC 62443.
In manufacturing, the A2H254-16 P0973BK connects PLCs, HMIs, and robotics systems, enabling real-time monitoring and control of production lines. Its QoS features ensure that automation signals (e.g., emergency stop commands) are prioritized over non-critical traffic, minimizing downtime and improving safety. In power generation, the switch supports SCADA systems in substations, routing data from remote sensors to central control rooms while resisting electromagnetic interference (EMI) from high-voltage equipment.
For transportation, the switch complies with EN 50155 (railway standards), making it suitable for on-board networks in trains or traffic management systems. It reliably handles video feeds from surveillance cameras and real-time passenger information systems, even in vibrating or high-temperature environments. Across industries, the switch solves challenges like:
- Network Congestion: Layer 3 routing and QoS optimize traffic flow in high-data environments.
- Environmental Risks: Rugged design ensures operation in extreme temperatures, shocks, and EMI.
- Security Vulnerabilities: Advanced security protocols protect against evolving cyber threats in IIoT networks.
- ENTERASYS A2H254-24 P0974BK – 24-port variant for larger industrial networks.
- ENTERASYS A2H254-16G P0973BK – Includes SFP slots for fiber optic connectivity.
- ENTERASYS A4800-48 P0975BK – 48-port Layer 3 switch for enterprise-level industrial applications.
- ENTERASYS A2H254-16-DC P0973DK – DC-powered version for industrial environments with 24V DC infrastructure.
- ENTERASYS A2H254-16-Lite – Budget-friendly variant with basic Layer 2 features.
Installing the A2H254-16 P0973BK involves rack-mounting the switch in a control cabinet using the included brackets. For outdoor or harsh environments, consider using a weatherproof enclosure. Key setup steps include:
- Power Redundancy: Connect both power inputs (if available) for fault tolerance.
- Network Configuration: Use ExtremeXOS or the web interface to enable VLANs, QoS, and routing protocols.
- Cable Management: Use shielded Cat6/Cat7 cables for high-speed data and separate power/signal cabling to reduce EMI.
For maintenance:
- Firmware Updates: Regularly update to the latest ExtremeXOS version for security patches and new features.
- Health Monitoring: Use SNMP or the web interface to monitor port status, temperature, and power supply health.
- Environmental Checks: Clean dust from vents in high-dust environments and verify vibration mounts are secure.
