Description
GE IS420ESWAH3A
Technical Specifications:
- Series: GE Mark VIe / Mark VIeS
- Product Type: Unmanaged IONet/Industrial Ethernet Switch (ESWA series)
- Copper Ports: 8 × 10/100Base-TX RJ45
- Fiber Ports: None
- Standards: IEEE 802.3, 802.3u, 802.3x
- Auto-Negotiation: 10/100 base copper, full/half duplex
- FX Uplink: Not applicable (no fiber ports)
- HP-MDIX: Auto-sensing
- Buffer: Minimum 256 KB
- MAC Addresses: 4K
- Power Input: 24/28 V DC, redundant dual power input (diode OR’d)
- Operating Temperature: -40 °C to +70 °C
- Cooling: Convection (no fan)
- Installation: DIN rail or panel mount
- Dimensions: 18.8 cm (H) × 8.6 cm (W) × 5.6 cm (D)
Functional Features:
- Same buffering and soft-start capabilities as other ESWA series switches
- All-copper connectivity for local IONet device aggregation
- Redundant dual power inputs
- LED indicators: power LED, plus per-port link and activity LEDs (yellow = 10 MB link, green = 100 MB link, no LED = no link; flashing green activity = full duplex, flashing yellow = half duplex)
- Supports DIN-rail or panel mounting in parallel or vertical orientation
- No fiber ports, reducing cost and complexity for all-copper installations
Application Scenarios:
- Local IONet switching within Mark VIe control cabinets
- Turbine control systems where all I/O packs and controllers are within copper cabling distance
- Safety-critical Mark VIeS networks requiring simple, reliable Ethernet switching
- Industrial automation environments with concentrated network topologies
Performance Parameters:
- Wire-speed forwarding on eight copper ports
- Low latency for real-time IONet communication
- Robust multicast and broadcast buffering
- Industrial-grade reliability with redundant power and wide temperature range
Material and Structural Characteristics:
- Industrial-grade metal housing with convection cooling
- Eight RJ45 ports on the front panel
- DIN-rail mounting clips (259B2451BVP1 for horizontal, 259B2451BVP4 for vertical) or panel-mount with screws
- LED indicators for power, link, and activity per port
Working Principle: The switch forwards Ethernet packets between eight copper-connected IONet devices, buffering multicast and broadcast streams with per-port packet buffering. It auto-negotiates speed and duplex, uses HP-MDIX for cable orientation, and operates from redundant 24/28 V DC power inputs. The absence of fiber ports simplifies deployment for localized control cabinet networking. Installation Requirements:
- Mount on DIN rail using clips (259B2451BVP1 or 259B2451BVP4) or panel-mount with screws
- Connect 24/28 V DC to redundant power inputs
- Wire copper ports using Cat 5e or better UTP cabling with RJ45 connectors
- Ensure adequate ventilation for convection cooling
- Use appropriate mounting orientation (parallel or vertical) based on cabinet layout
Usage Notes:
- This model has no fiber ports; select ESWAH2A or ESWAH4A for fiber uplink requirements
- Monitor LED indicators for link status (yellow/green) and activity (flashing green/yellow for duplex)
- Avoid exceeding 200 insertion/removal cycles on RJ45 connectors
- Confirm power supply voltage and polarity before energizing
- Replace with identical ESWA series models to maintain network configuration
