Description
GE Mark VIe IS420ESWBH1A IONet Ethernet Switch Product Specification
The
GE Mark VIe IS420ESWBH1A is a
16-port industrial Ethernet switch designed for GE Speedtronic Mark VIe turbine control systems. It combines
16x 10/100Base-TX copper ports with
1x 100Base-FX multimode fiber port (LC connector), enabling hybrid copper-fiber network configurations for power generation, oil & gas, and industrial automation. With
wide-temperature operation (-40°C to 70°C) and
unmanaged plug-and-play functionality, the
IS420ESWBH1A ensures reliable connectivity in harsh environments.

IS420ESWBH1A
- Hybrid Network Flexibility: Combines copper and fiber ports for long-distance fiber connections (up to 2km with multimode fiber) and short-range copper links, reducing cabling complexity.
- Harsh Environment Tolerance: Operates in extreme temperatures and humidity (0–95% non-condensing), making it suitable for outdoor or industrial settings.
- Plug-and-Play Simplicity: Unmanaged design requires no configuration, ideal for quick deployment in basic networks.
- Buffered Packet Handling: Stores excess multicast/broadcast packets to prevent data loss during high-traffic periods.
Industries:
- Power Generation (gas/steam turbines, combined cycle plants)
- Oil & Gas (pipeline monitoring, compressor control)
- Manufacturing (factory automation networks)
Application Case:
A chemical plant used IS420ESWBH1A to connect 16 field devices to a central control system via copper ports while extending the network 1.5km using the fiber port. The switch’s wide-temperature rating ensured stable operation in 60°C summer conditions, reducing network failures by 80%.
Compared to similar industrial switches:
- Fiber Integration: Unique 16-copper + 1-fiber port design vs. standard 8-copper + 2-fiber configurations in competing models.
- Wider Temperature Range: -40°C start-up vs. -20°C minimum for some alternatives.
- GE Compatibility: Native integration with Mark VIe systems without third-party gateways.

IS420ESWBH1A
- Network Topology: Choose IS420ESWBH1A for mixed copper-fiber networks; use IS420ESWBH3A (16 copper ports) for all-copper setups.
- Environment: Opt for this model if operating below -20°C or above 50°C.
- Cost: Unmanaged design offers lower upfront costs than managed switches for basic applications.
- Cabling: Use Cat5e/6 UTP cables for copper ports (max 100m) and 50/125μm multimode fiber for the fiber port.
- Mounting Clips: Requires GE clips 259B2451BVP1 (parallel) or 259B2451BVP4 (perpendicular) for DIN-rail installation.
- LED Troubleshooting: Steady green link LED = 100Mbps; flashing yellow activity = half-duplex mode.
