GE IS420ESWAH3A IONet Ethernet Switch
Product Specifications:
The GE IS420ESWAH3A is an Industrial Ethernet IONet Switch engineered for real-time industrial control solutions, delivering speed and functionality critical for dynamic operational environments. Unlike other ESWA-series switches, it stands out as the only model without fiber ports, instead relying on copper connectivity. It adheres to core Ethernet standards and integrates user-friendly features like HP-MDIX auto-sensing and power-indicating LEDs, making it a reliable choice for industrial control systems requiring consistent data transmission.
Key Features:
Distinctive Copper-Centric Port Configuration:The switch features eight front-facing 10/100Base-TX copper RJ45 ports—its most defining trait, as it is the sole ESWA model lacking fiber ports. This copper-focused design simplifies integration with copper-based industrial networks, catering to setups where fiber connectivity is unnecessary, while still ensuring 10/100 Mbps speed for real-time control data.
Targeted Packet Buffering for Multicast/Broadcast Streams:It relies on packet buffering to manage continuous multicast or broadcast data flows, a critical capability for industrial control (where such streams are common). However, it buffers only one incoming stream at a time; remaining streams are queued for later transmission. GE recommends using one packet per port to optimize buffering efficiency, preventing bottlenecks and maintaining steady data flow.
Performance-Driven ArchitectureThree core performance criteria define its operation:
Inrush current management: Prevents power spikes during startup, protecting connected equipment.
Low switch latency: Ensures minimal delay in data transmission, vital for real-time control responsiveness.
Store-and-forward architecture: Validates data integrity before forwarding packets, boosting confidence in handling high data volumes without errors—critical for industrial systems where data accuracy directly impacts operational safety.
Standards Compliance & User-Friendly Diagnostics:It complies with IEEE 802.3 (Ethernet), 802.3u (Fast Ethernet), and 802.3x (flow control) standards, ensuring compatibility with existing industrial networks. HP-MDIX auto-sensing eliminates the need for crossover cables, simplifying installation.
