Overview

LT20GF series are 20-port DIN mount layer-2 managed Ethernet switch with 16x10/100/1000Base-T(X) and 4xGigabit combo ports with SFP socket. These switches are designed for power substation application, and it is fully compliant with the requirement of IEC 61850-3 and IEEE 1613. These switches support Ethernet Redundancy protocol, LK-Ring (recovery time < 30ms), LK-Chain, MRP *, Fast Recovery and MSTP (RSTP/STP compatible) can protect all mission-critical applications from network interruptions or temporary malfunctions with its fast recovery technology.


LT20GF series can be managed centralized and convenient by Open-Vision, as well as the web-based interface, Telnet and console (CLI) configuration. Therefore, the switch is one of the most reliable choices for highly managed and Fiber Ethernet application.
