FUNCTIONAL DESCRIPTION:

IS420ESWAH2A REV B is an Ethernet IONet 10/100 Switch manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Gas Turbine Control Systems. The ESWAH2A Industrial Ethernet Switch is purpose-built for demanding industrial environments, providing high-speed, reliable Ethernet communication even under harsh operating conditions. It is a critical component in turbine control systems, facilitating seamless and real-time data exchange between control modules, monitoring devices, and safety systems. This ensures efficient operation, rapid response, and enhanced system reliability.

Equipped with 8 ports supporting 10/100BASE-TX, it serves as an essential element for all IONet switches used in Mark VIe and VIeS safety control systems, ensuring consistent network performance for both standard and safety-critical operations. The module supports DIN-Rail mounting, allowing for quick installation within industrial control panels while maintaining a compact and organized layout. When replacing an existing switch, the included port adapter ensures compatibility, enabling a smooth connection from an existing SC fiber termination to the LC fiber port without requiring additional hardware.

• Industrial Reliability: Designed to withstand harsh conditions typical of industrial environments, including vibration, temperature fluctuations, and electrical noise.
• High-Speed Connectivity: 8 copper ports with 10/100BASE-TX, supporting fast, stable communication for real-time control.
• Standards Compliance: Fully compatible with IEEE 802.3, 802.3u, and 802.x standards.
• Flexible Duplex Operation: Auto-negotiation supports full and half-duplex communication for versatile network configurations.
• Fiber Uplink Support: 100 Mbps FX uplink port ensures high-speed data transfer and network expansion.
• Easy Connectivity: HP-MDIX auto-sensing eliminates the need for crossover cables.
• Visual Indicators: Dual-color LEDs display link status, activity, duplex mode, and speed; power status LED ensures quick troubleshooting.
• Memory & Addressing: 256KB buffer with 4K MAC address capacity allows efficient handling of high network traffic.
• Redundant Power Inputs: Enhances system reliability and ensures continuous operation in critical industrial processes.

ETHERNET SWITCH FLOW CONTROL:

The ESWAH2A Industrial Ethernet Switch supports advanced flow control using IEEE-defined pause packets, ensuring smooth and efficient data transmission across the network. The switch intelligently responds to incoming pause requests and sends pause signals only when required, preventing network congestion and maintaining consistent performance in real-time control applications.

Designed for high-reliability industrial environments, the switch is built to meet stringent operational demands. It boasts an impressive Mean Time Between Failures (MTBF) exceeding 4 million hours at 35°C (95°F) under controlled, ground-fixed conditions, providing exceptional durability and long-term operational stability. This combination of precise flow control and outstanding reliability makes the ESWAH2A an ideal solution for critical industrial and turbine control systems where uninterrupted communication is essential.

CONFORMANCE CRITERIA:

The ESWAH2A Industrial Ethernet Switch is engineered for precise, real-time industrial communication. It supports IEEE 1588 Precision Time Protocol (PTP) timing, enabling packet traffic to be synchronized and triggered to start within a 1-microsecond window. This high level of timing accuracy ensures deterministic data delivery, which is critical for turbine control systems, safety devices, and other time-sensitive industrial applications.
