The ComNet CNGE3FE7MS4 is a substation-rated and industrially hardened fully managed layer 2 gigabit Ethernet switch. Fully compliant with the requirements of IEC 61850-3, IEEE 1613 Class 2, UL 508 Class 1/ Division 2 (Groups A, B, C, & D for hazardous environments), EN50155, and NEMA TS-1/ TS-2, it is designed for deployment in environments where high levels of electromagnetic noise and interference (EMI) and severe voltage transients and surges are routinely encountered, such as electrical utility substations and switchyards, heavy manufacturing facilities, trackside and roadside electronic equipment, and other difficult out-of-plant applications. Providing (7) 10/100 BASE-TX ports, the (3) 10/100/1000TX or 100/1000BASE-FX user-configurable combo gigabit uplink ports support conventional CAT-5e/CAT-6 copper or optical transmission media by selection of the appropriate ComNet SFP module. Featuring an internal/self-contained 85-264 VAC/88-373 VDC power supply, the CNGE3FE7MS4 is DINrail or wall-mountable, and is ideal for mission-critical applications where very high levels of reliability and network availability are of the utmost importance. Utilizing exclusive ComNet C-Ring technology, the fastest recovery redundant ring available, network recovery time of <10 ms is provided for protection from network faults or temporary interruptions. ComChain permits additional redundant network rings of different redundancy protocols to function together as a larger and more robust network topology. eConsole, a Windows-based utility, is included for centralized/remote management and configuration of all functions of the CNGE3FE7MS4.

Features for CNGE3FE7MS4

  • Provided HTTPS/SSH protocol enhances network security
  • DDM (Digital Diagnostic Monitoring) remotely ascertains the status of the operating voltage, current, and operating temperature of the SFP modules
  • Fully compliant with the requirements of IEC 61850-3 and IEEE 1613 Class 2 for electrical utility substations, EN50155 for railway applications, and NEMA TS-1/TS-2 for traffic signal control equipment
  • Port based VLAN (IEEE 802.1Q)
  • Fully configurable through web-based or SNMP network management
  • Compliant with EN60950-1 and UL 508 Class 1, Division 2 (Groups A, B, C & D) for use in Hazardous Locations
  • Environmentally hardened for deployment in difficult unconditioned out-of-plant and roadside installations
  • PTP Client for precision time protocol clock synchronization
  • Internal/self-contained universal high-voltage power supply: 85-264 VAC/88-373 VDC operating range. Redundant power supply capability significantly reduces the possibility of a single-point-of-failure for the highest possible system and network reliability
  • Utilizes C-Ring, the fastest redundant Ethernet ring available; Recovery time <10 ms with 250 units within a ring. Fully compatible and interoperable with the Moxa Turbo Ring topology using ComRing technology, and ComNet X-Ring, Dual-Homing, Couple Ring, and DualRing Topologies
  • Supports ComChain, the ComNet-exclusive technology that provides add-on network redundancy topology to any backbone network. ComChain allows multiple redundant network rings of different redundancy protocols to join and function together as a larger and more robust compound network topology, while maximizing fault-recovery speed, flexibility, compatibility, ease of use, and cost-effectiveness.
  • Fault/event notification provided through Syslog, e-Mail, SNMP trap, or relay alarm output
  • 10/100 BASE-T(X), 10/100/1000T(X), and 100/1000 BASE-FX compatible
  • IGMP Snooping V1/V2/V3 for multicast filtering, and IGMP Query V1/V2
  • No fans or forced-air cooling; cooling via natural convection eliminates unreliable and troublesome fans/moving parts, with no periodic maintenance requirements.
  • Uses customer-installed ComNet SFPs for compatibility with a wide range of optical fibers, optical connector types, and optical transmission distances (SFPs ordered separately).
  • Electric Port Supports Auto-negotiation for Full Duplex or Half Duplex Data Throughput
  • Web-based, Telnet, Console (CLI), and Windows-based utility (eConsole) configuration
  • Rigid aluminum housing
  • Designed for wall or DIN rail mount installations


  • Electrical substation automation & SCADA networks, protective relaying systems
  • Power transmission & distribution systems, remote wind farm, hydroelectric, and solar/photovoltaic power generation facilities, and other electrical utility-specific applications
  • Perimeter security, surveillance monitoring, and controlled access to electrical substations and power generating facilities, and other high-value, mission-critical sites
  • Industrial/Factory Automation & Process Control SCADA Networks
  • Chemical and petrochemical refining and processing facilities, oil and gas pipelines/transmission systems, and mining installations
  • Food processing operations
  • Wastewater treatment plants
  • ITS/Transportation Traffic Signalization & Surveillance/Incident Detection Networks
  • Railway/trackside control and monitoring systems
  • Integrated IP-Video, VOIP, and Data Transmission Networks
  • Cellular telephony and wireless backhaul networks
