Reason S20 Managed Ethernet Switches GE

Ethernet Switch GE’s Reason S20 series of managed Ethernet switches are designed to enable an IEC 61850 digital substation network, including IEEE 1588v2 (PTP), in harsh environments within power systems and industry applications. 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 models offer full cyber security features by default, including RADICUS/TACACS+ remote authentication technology, password encryption and digitally signed firmware, enabling operators to fully comply with NERC CIP guidelines and regulations. Statistical information and file management can be operated using SNMP v3.
