Specifications

Description

IS420ESWAH1A is a 10/100 Ethernet IONet Switch manufactured and designed by General Electric as part of the Mark Vle Series used in GE Distributed Gas Turbine Control Systems. These switches are available in both managed and unmanaged configurations. Managed switches provide advanced networking features such as VLANs (Virtual Local Area Networks), Quality of Service (QoS), and remote monitoring, making them ideal for complex network architectures requiring segmentation and prioritization. On the other hand, unmanaged switches offer a simpler, plug-and-play setup, which is beneficial for straightforward networking needs where minimal configuration is required. Additionally, many industrial-grade Ethernet IONet switches are built with rugged enclosures, redundant power supply options, and enhanced electromagnetic compatibility (EMC) protection, ensuring reliable operation in harsh environments.

Applications

Power plants (core application, responsible for high-speed real-time data exchange between gas turbines, steam turbines, and the entire plant's DCS)
Nuclear power plants (for highly secure and deterministic digital control networks)
Chemical plants (establishing a redundant network backbone for the plant's distributed control system)
Oil refineries (supporting large-scale cross-regional unit networking and signal monitoring)
Natural gas liquefaction plants (ensuring low-latency communication during cryogenic storage and transportation)
Steel plants (for complex automated rolling lines and blast furnace interlocking networks)

Feature

Compatible with 802.3, 802.3U, and 802.x standards

10/100BASE-TX copper ports with auto-negotiation

Supports full and half-duplex auto-negotiation

100 Mbps FX uplink port

HP-MDIX auto-sensing for easy connectivity

Dual-color LEDs for link status, activity, duplex mode, and speed indication

Power status LED indicator

256KB buffer with 4K MAC address capacity

Redundant power supply inputs for reliability

FLOW CONTROL

The switch supports flow control with IEEE-defined pause packets, responding to requests and transmitting them only when needed. Engineered for high reliability in control systems, it achieves over 4 million hours MTBF at 35°C (95°F) in a stable, ground-fixed environment

CONFORMANCE CRITERIA

The packet traffic can be synchronized by IEEE 1588 timing and triggered to initiate within a 1-microsecond packet start window. The switch' s capability and conformance are tested to meet the following four criteria:

1 Multicast packet load initiated on one port without IEEE 802.3x flow control.

2 Multicast packet load initiated on one port with IEEE 802.3x flow control.

3 Multicast packet load distributed across all ports, averaging the required packet count per port, without IEEE 802.3x flow control.

4 Multicast packet load distributed across all ports, averaging 200 packets per port, with IEEE 802.3x flow control enabled on half the ports.

FAQ

Q: What is a 10/100 Ethernet IONet Switch IS420ESWAH1A?
A: A 10/100 Ethernet IONet switch is a network device designed to support Ethernet speeds of 10 Mbps and 100 Mbps, making it ideal for industrial automation and control systems. It ensures seamless communication between various devices, such as PLCs, HMIs, sensors, and actuators, within networks used in power plants, SCADA systems, and distributed control systems (DCS).

Q: What flow control mechanisms does the IS420ESWAH1A support?
A: The switch implements IEEE 802.3x full-duplex flow control using pause frames, allowing it to respond to incoming pause requests and issue pause frames only when network congestion occurs. This prevents packet loss due to buffer overflow and optimizes transmission efficiency between devices such as PLCs, HMIs, and remote I/O units.

Q: What is the Mean Time Between Failures (MTBF) of the IS420ESWAH1A?
A: The switch is designed for long-term reliability, achieving a Mean Time Between Failures (MTBF) of over 4 million hours at 35°C (95°F) in a ground-fixed, controlled environment. This high MTBF rating ensures continuous, trouble-free operation for years, making it a dependable choice for mission-critical networks.
