More Information

Overview Manuals Copper Fit Power Arrangement Link Validation Applications

Features:

  • Eight RJ45 connections concentrate copper IONet traffic inside the control cabinet.
  • A copper-only design separates H3A from the fiber-equipped H1A option.
  • Dual diode-ORed DC inputs support a resilient panel power arrangement.
The H3A suffix identifies the ESWA configuration intended for eight copper network connections without an optical port.

DIN-rail mounting and convection cooling support integration into established Mark VIeS cabinet layouts.

Accurate replacement depends on comparing the suffix and port map with the installed network drawing.

Apter Power can support sourcing and technical review for the General Electric IS420ESWAH3A IONet Ethernet Switch.

  • H3A suits cabinet designs that keep all eight IONet connections on copper cabling.
  • Existing port labels and peer-device assignments provide the clearest reference for restoring the original topology.
  • A design requiring multimode fiber points to H1A rather than this copper-only configuration.
  • Two diode-ORed DC inputs allow the switch to participate in a redundant 24/28 Vdc supply scheme.
  • DIN-rail mounting supports orderly cabinet replacement while preserving cable routing and service access.
  • Grounding and open airflow around the enclosure contribute to stable convection-cooled operation.
  • Port-by-port link indications help confirm that each documented cabinet connection has returned.
  • A final comparison with the network drawing reduces the chance of swapped copper destinations.
  • Apter Power can review the complete model and topology record before shipment to support accurate selection.
  • Mark VIeS IONet cabinets using eight copper Ethernet connections and no fiber uplink.
  • Maintenance projects that must preserve the installed H3A hardware suffix and RJ45 port arrangement.
  • Turbine-control network service supported by documented redundant power and cabinet wiring.
Description
IS420ESWAH3A provides eight 10/100Base-TX RJ45 ports for copper IONet connections in a compatible GE Mark VIeS control network; the H3A configuration has no fiber interface.

IS420ESWAH3A suits cabinet layouts that keep every local network leg on copper, avoiding an unnecessary media interface while preserving the required port count.

IS420ESWAH3A uses dual diode-ORed 24/28 Vdc inputs, DIN-rail mounting and convection cooling. Apter Power can review the installed port map, documents and sourcing requirement.

Technical notes
A smooth commissioning plan benefits from confirming both DC feeds, grounding, RJ45 assignments and cabinet airflow. The main selection risk is confusing H3A with the fiber-equipped H1A and creating a topology mismatch. Apter Power can compare the nameplate and network drawing before shipment.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Where does IS420ESWAH3A fit in a Mark VIeS IONet cabinet?
It provides eight copper Ethernet connections where the documented cabinet design does not require a fiber interface.
How is IS420ESWAH3A different from H1A?
H3A is the copper-only version. H1A adds a multimode LC fiber interface, so the cabinet network drawing should guide selection.
Which records help verify an IS420ESWAH3A replacement?
The full nameplate, existing port map, DC feed arrangement and cabinet drawing help our team compare the required switch with the installed unit.
Can IS420ESWAH3A receive redundant DC power?
Yes. GE documents two diode-ORed 24/28 Vdc inputs for the switch when wired within the intended cabinet design.
What supports a smooth IS420ESWAH3A commissioning check?
Confirming DC power, grounding, cable labels and peer-device link indications helps show that the original copper topology has been restored.
How can Apter Power assist with IS420ESWAH3A?
We provide quotations, technical documents, sourcing assistance and model-specific topology review without implying an OEM stock or delivery commitment.
