Using the Reason S20, packet switching between substation devices is flexible, reliable and robust, even in situations where routing is necessary. A flexible, modular design allows the Reason S20 series to support a wide range of network architectures. The Reason S20 series includes the following models: S2020, the cost-effective choice, offers a high density of Ethernet ports in a 1U form factor for easy rack mounting. This model supports up to 5 modules with 4 ports each and allows configurations with up to 20 fast Ethernet ports or up to 4 gigabit ports plus 16 fast Ethernet ports. S2024, the premium model, offers full gigabit Ethernet switch functionality. This model supports up to 24 ports, provided by 6 interface modules with 4 ports each. The 1U mechanical design is identical to the S2020 model. In both S2020 and S2024 models, layer 3 functions and IEEE 1588v2 PTP (all ports, hardware-based) can be upgraded via a licensing file. The Reason S20 switches can be configured and managed cyber-securely using an SSH command line interface or an HTTPS graphical interface. Both switches support RADIUS and TACACS+ remote authentication technology. Statistical management information can be accessed using SNMP v2/v3. What's New Key Benefits Cyber Security Design IEC 61850 Networks IEEE 1588v2 SFP Transceivers Layer 3 functionalities (FW 07A) S20 is now a Layer 2 and 3 Managed Ethernet Switch, featuring the following protocols: Routing Information Protocol (RIP) version 1 and 2 - RFC 1058 and RFC 2453 Open Shortest Path First (OSPF) version 2 - RFC 2328 Virtual Router Redundancy Protocol (VRRP) - RFC 2338 Static Routing Supervisory monitoring enhancements (FW 07A) New failsafe function to detect Ethernet port link up/down from each interface separately. New SNMP OIDs to share the equipment Serial Number and internal temperature. New order code S2024G is now called S2024 (without G). S2020 and S2024 order codes were merged to a single order code: Number of ports (20 or 24) is chosen through the configurator (cortec) – this cannot be upgraded from 20 to 24 ports in the field; Layer 3 functions and IEEE 1588v2 PTP may be upgraded via a licensing file, available for both models S2020 and S2024. Cyber Security (FW 06A02 or greater) By default, S20 delivers cyber security features that helps customers comply with NERC CIP requirements by supporting the following core features: Password Complexity and Encryption AAA Server Support (Radius/TACACS+) Role Based Access Control (RBAC) Firmware digitally signed Syslog CONTACT INFORMATION PRIVACY COOKIES TERMS OF USE About Grid Solutions GE's Grid Solutions business serves customers globally with over 17,000 employees in approximately 80 countries.
