General Electric IS42yESWBH2A Industrial Ethernet Switches
Core Hardware and Port Configuration
Port Combination: 16 10/100Base-TX RJ45 copper ports (supporting HP-MDIX auto-sequencing, 10/100M auto-negotiation, full/half-duplex negotiation, and IEEE 802.3x flow control) + 2 100Base-FX multimode fiber optic LC ports; the RJ45 copper ports are resistant to 200 mating cycles.
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-FX multimode LC ports; multimode 50/125μm or 62.5/125μm fiber transmission distance ≤2km, suitable for short to medium distance inter-factory communication; requires GE dedicated IR SFP multimode optical module.

Redundancy and Safety Features
Power Redundancy: Dual 24-28VDC inputs, diode OR protection, hot-swappable, 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, deployable in control cabinets in hazardous areas, meeting SIS system safety requirements.
Dual Fiber Redundancy: Two multimode fiber ports support redundant ring networks, improving the reliability of short-to-medium distance backbone links and avoiding single-point failures.
Typical Applications and Deployment Recommendations
High-Density I/O Access + Dual Multimode Fiber Redundant Backbone: Mark VIeS system IONet backbone network, connecting 16 local I/O modules/controllers downstream and a dual multimode fiber redundant backbone upstream, suitable for centralized I/O communication scenarios in large turbine units.
Medium-to-short distance multimode fiber optic dual-redundancy expansion: Connects to remote operation stations or area controllers, adaptable to medium-to-short distance (≤2km) cross-plant communication, with dual fiber optic links ensuring high reliability.
Security control network expansion: The area-level switch of the SIS security system connects security I/O modules and security controllers, ensuring reliable transmission of security control signals.
Spare parts upgrade: Directly replaces aging 16-port dual multimode fiber optic switches, improving port density and redundancy; no configuration changes are required during replacement, plug and play.
