Substation-Rated Managed Ethernet Switch

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 substations and switchyards.

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 DIN-rail 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, a fast recovery redundant ring, 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.
