GE IS420ESWDH5A

Product Type: Managed Ethernet Switch Module for Industrial Control

Product Introduction:
The IS420ESWDH5A is a 48-port managed Ethernet switch designed for the GE Mark VIe and Mark VI control systems. It provides high-bandwidth, deterministic communication for turbine and generator control networks. The module operates within the Mark VIe distributed control architecture, supporting both Gigabit Ethernet (1000 Mbps) and Fast Ethernet (100 Mbps) port speeds.

Functional Features:

  • 48 Gigabit Ethernet ports with auto-negotiation
  • Layer 2 managed switch with full CLI configuration
  • VLAN segmentation for traffic isolation between control domains
  • Quality of Service (QoS) prioritization for time-critical control traffic
  • Port mirroring (SPAN) for network diagnostics
  • IGMP snooping for multicast traffic optimization
  • Storm control to prevent broadcast/multicast storms
  • Link aggregation (LACP 802.3ad) support on selected port groups
  • Secure management via SSHv2, SNMPv3, and RADIUS/TACACS+
  • Redundant ring topology support via RSTP for zero-downtime failover

Structural Features:

  • Compact 1U-equivalent form factor for Mark VIe chassis mounting
  • Front-panel LED indicators for port status, link, speed, and activity
  • Hot-swappable module compatible with Mark VIe backplane
  • Ruggedized PCB design with conformal coating for industrial environments

Applicable Industries:

  • Power Generation (Gas Turbine, Steam Turbine, Combined Cycle)
  • Oil & Gas (Refinery, Pipeline SCADA)
  • Petrochemical Plants
  • Water/Wastewater Treatment Facilities

Installation Requirements:

  • Mount in Mark VIe or Mark VLM chassis only
  • Ensure redundant DC power is connected to backplane
  • Connect fiber or copper Ethernet cables (Cat5e/Cat6 recommended for 1 Gbps)
  • Configure IP addressing and VLANs via CLI or Web interface before deployment

Usage Precautions:

  • Do not exceed maximum switching capacity of 88 Gbps
  • Maintain ambient temperature below 55°C
  • Use shielded Ethernet cables in high-EMI environments
  • Update firmware only via GE approved procedures
  • Do not mix with non-GE managed switches in the same control network
