FUNCTIONAL DESCRIPTION:
IS420ESWAH5A is a 10/100 Ethernet IONet Switch manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Gas Turbine Control Systems. IONet switches are unmanaged, fully switched, and full-duplex to prevent collisions. They provide data buffering and flow control during the critical input scan. Only industrial-grade switches that meet the codes, standards, performance, and environmental criteria for industrial applications are used for the IONet. GE industrial Ethernet 10/100 IONet switches (ESWA and ESWB) have an operating temperature of -40 to 70 °C (-40 to 158 °F), have provisions for redundant 18 to 36 V dc power sources (200/400 mA), and can be DIN-rail mounted. The switches also provide LEDs to indicate the status of the IONet link, speed, activity, and duplex.
ETHERNET SWITCH FLOW CONTROL:
The switch incorporates IEEE-standard flow control using pause frames, enabling efficient network traffic management by temporarily halting data transmission during periods of congestion. This proactive traffic regulation helps maintain optimal performance and prevents packet loss in demanding environments. Engineered specifically for mission-critical industrial control systems, the switch delivers exceptional reliability with a mean time between failures (MTBF) exceeding 4 million hours at 35°C (95°F) under stable, ground-fixed conditions. Its rugged design ensures consistent performance in harsh environments, supporting long-term deployment with minimal maintenance. Its robust architecture is also ideal for applications requiring uninterrupted communication, such as manufacturing automation, power generation, and transportation systems.
I/O PACK ETHERNET ADDRESSING:
On the IONet, I/O packs are assigned IP addresses through the DHCP servers in the controllers. The Host ID presented to the DHCP server is based on the board type and serial number information stored on a serial EEPROM located on the terminal board. Since the Host ID is part of the terminal board, the I/O pack can be replaced without having to update the ToolboxST application or controller communication IDs.
IONets are Class C networks. Each is an independent network with different subnet addresses. The IONet IP host addresses for the controllers are fixed. The IP addresses of the I/O packs are assigned by the ToolboxST application, and the controller automatically distributes the addresses to the I/O packs through a standard Dynamic Host Configuration Protocol (DHCP) server in the controllers.

How many ports does it support?
The switch is equipped with 8 RJ-45 copper ports, each supporting 10/100Base-TX Ethernet. It offers auto-negotiation, allowing automatic selection of the best network speed and duplex mode. With HP-MDIX auto-sensing it ensures seamless connectivity without requiring manual crossover cables, which adds flexibility in network setups.
What type of network standards does it support?
This Ethernet IONet Switch complies with key IEEE standards, including 802.3, 802.3u, and 802.x. These standards ensure reliable communication and interoperability with other industrial networking equipment. By adhering to these established protocols, the switch guarantees compatibility in a wide range of network environments, supporting the long-term integration of industrial control systems.
What power input is required?
The switch operates within a power range of +32 V DC to 18 V DC and is designed to support redundant power supply inputs (18–36 V DC). This dual power input setup ensures the switch remains operational even if one power source fails, enhancing its reliability for mission-critical applications where continuous uptime is a must.
