Switching Capacity: 1.6 Gbps (8 ports × 200 Mbps)

Forwarding Rate: ~1.19 Mpps

Packet Buffer: ~256 KB total shared memory

Indicators: Per-port LEDs for Link/Activity and Speed; dual-color power-source LED

Power: 24 – 28 V DC, ≤ 3 W

Mounting: DIN-rail (clips ordered separately) or panel with screws

Operating Temp.: –40 °C to +85 °C

Storage Temp.: –40 °C to +85 °C

Humidity: 5 % to 95 % RH, non-condensing

Shock/Vibration: IEC 60068-2 compliant

Ingress Protection: IP30

Product function

GE IS420ESWAH3A IONet Ethernet Switch Unmanaged Layer-2 Switching: Transparent forwarding of Ethernet frames between connected IONet/Ethernet devices.

Auto-MDIX & Auto-Negotiation: Simplifies cabling; automatically adapts to straight or crossover cables and port speed/duplex.

Industrial Reliability: Designed for continuous operation in harsh control-room and cabinet environments with extended temperature range and vibration tolerance.

Multicast/Broadcast Handling: Buffers one high-volume stream to prevent network overload; additional streams are queued.

Core supporting modules

GE IS420ESWAH3A DIN-Rail Mounting Clips:

259B2451BVP1 (long-edge parallel)

259B2451BVP2 (long-edge perpendicular)

Redundant Power Supply Module: RPS6U series provides 24 V DC redundancy for Mark VIe racks

Patch Panels & Cable Assemblies: GE-qualified shielded RJ-45 cables for IONet installations

Extension components

ESWB Fiber-Port Variants: IS420ESWBH3A for multi-mode fiber uplink (for longer-reach links)

Managed Ethernet Option: IONet-managed switches (e.g., IS435ESW*) for VLAN/QoS and diagnostic features

Ethernet Surge Protectors: Inline surge-suppression modules to guard against lightning/transient voltages on 10/100 TX lines

Software support

GE IS420ESWAH3A Unmanaged Operation: No configuration software required; plug-and-play.

Network Diagnostics: Link/Activity LEDs and speed indicators provide basic visibility.

Integration with Mark VIeS Systems: Frame forwarding optimized for IONet protocols used by turbine controllers.

Hardware Monitoring: External SNMP-based rack-level status via separate management modules (optional GE-OSP modules).
