General Electric IS42yESWAH5A Industrial Ethernet Switches
Core Hardware and Port Configuration
Port Combination: 8 x 10/100Base-TX RJ45 copper ports (supports HP-MDIX auto-sequencing, 10/100M auto-negotiation, full/half-duplex negotiation, IEEE 802.3x flow control) + 2 x 100Base-LX10 single-mode fiber optic LC ports; RJ45 copper ports are 200 mating cycles resistant.
Buffer and Address: 256KB buffer, 4K MAC address table, non-blocking full-switching architecture, ensuring low-latency transmission of real-time control data.
Power Supply and Installation: 24-28VDC redundant power supply (Phoenix Contact connector, hot-swappable), standard DIN rail mounting, vertical/horizontal adaptation, natural convection cooling.
Fiber optic characteristics: Two 100Base-LX10 single-mode LC ports; single-mode 9/125μm fiber transmission distance ≤10km, suitable for long-distance inter-factory communication; requires GE dedicated IR SFP single-mode optical module.

Redundancy and Safety Features
Power Redundancy: Dual 24-28VDC inputs, diode OR protection, hot-swappable replacement, avoiding single-point-of-failure power supply.
Harsh Environment Resistance: Metal casing, strong EMC performance, suitable for power plants, petrochemical plants, and other environments with strong electromagnetic interference and vibration shock.
Explosion-proof Compliance: Class 1 Div 2/ATEX certified, can be deployed in control cabinets in hazardous areas, meeting SIS system safety requirements.
Dual Fiber Redundancy: Two single-mode fiber ports support redundant ring networks, improving the reliability of long-distance backbone links and avoiding single-point failures.
Typical Applications and Deployment Recommendations
Long-distance Single-mode Fiber Dual Redundant Backbone: Mark VIeS system IONet backbone network, connecting remote safety I/O modules, controllers, and operator stations, suitable for long-distance (≤10km) high-reliability communication scenarios across plant areas.
Turbine Unit Remote Monitoring Network: The remote communication layer of the Mark VIeS TMR system for gas/steam turbines connects remote vibration/displacement modules, safety controllers, and operator stations, ensuring stable transmission of control signals.
Inter-plant Anti-interference Link: Single-mode fiber optic transmission replaces copper cables, avoiding strong electromagnetic interference within the plant area, suitable for long-distance control network interconnection across plant buildings.
Spare Parts Upgrade: Directly replaces aging dual-mode/single-mode fiber optic switches, improving long-distance transmission and redundancy capabilities; no configuration changes are required during replacement, plug and play.
