GE IS420ESWDH1A

Product Type: Managed Ethernet Switch Module

Product Introduction:
The IS420ESWDH1A is a 48-port Gigabit Ethernet managed switch for GE Mark VIe systems. It is an earlier hardware revision of the IS420ESWDH5A with identical core functionality but older firmware architecture. It provides Layer 2 switching with VLAN, QoS, and redundant ring support for turbine control networks.

Functional Features:

  • 48 Gigabit Ethernet ports with auto-negotiation
  • Layer 2 managed switch with CLI configuration
  • 802.1Q VLAN segmentation (up to 128 VLANs — fewer than H5A revision)
  • RSTP/STP for loop-free redundant topologies
  • 802.1p QoS with 4 priority queues
  • IGMP snooping for multicast optimization
  • Port mirroring (SPAN) for diagnostics
  • SNMP v1/v2c management (no SNMPv3 — limitation vs H5A)

Key Differences from IS420ESWDH5A:

  • SNMPv3 not supported (only v1/v2c)
  • Maximum VLANs: 128 (vs 256 in H5A)
  • Older firmware — no support for some newer security features
  • Identical hardware port count and switching capacity

Applicable Industries:

  • Legacy Power Plant Control Systems
  • Retrofit Projects (Existing Mark VIe Installations)
  • Gas/Steam Turbine Control Networks

Installation Requirements:

  • Mount in Mark VIe or Mark VLM chassis
  • Use Cat5e/Cat6 cables for Gigabit operation
  • Configure VLANs and QoS via CLI before network integration
  • Verify redundant power connection

Usage Precautions:

  • Firmware is not upgradeable to H5A feature set
  • Use SNMPv2c with community string security as best available option
  • Do not mix with IS420ESWDH5A in the same network segment without VLAN isolation
  • Maximum ambient temperature: 55°C
