Reason S20
Managed Ethernet Switches
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:
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. |
The firmware 07A07 versions adds Digital Diagnostics Monitoring (DDM) functionality for optical SFP transceivers as well as new alarms using the dry-contact relay or SNMP traps were add based on DDM measurements. For the full list of enhancements, please refer to the firmware release notes. |

Key Benefits
The flexible and robust Reason S20 Ethernet switches provide customers with a variety of benefits, including:
Cyber Security
The Reason S20 delivers advanced cyber security features that help operators to comply with NERC CIP guidelines and regulations. These features are standard with firmware 06A02 and greater.
AAA Server Support (Radius/TACACS+)
Enables integration with centrally managed authentication and accounting of all user activities and uses modern industry best practices and standards that meet and exceed NERC CIP requirements for authentication and password management.
Role Based Access Control (RBAC)
Efficiently administrate users and their privileges within S20 devices. Multiple users account with independent passwords and privilege levels (roles) may be created, and with an advanced function leveling it is possible to define the access level required for each predefined function. Attempts to log-in (either successful or failed) are stored in a persistent flash memory syslog. After three failed log-in attempts, the user account gets locked out and must wait 1 minute to retry new three attempts.
Password Complexity, Encryption and Expiration
Factory default password is different for each manufactured device and after the first login, users must change the password with at least 8 characters including lower/uppercase alphabetic, numeric and special non alphabetic characters (e.g. #, $, @, &). Passwords are encrypted using SHA256 and by default, it may expire after 6 months (user-configurable).
Firmware digitally signed and secure communications
To perform a secure firmware update, S20 uses the checksum algorithm to check firmware integrity and a digital signature to ensure its authenticity. In addition, only the encrypted Secure File Transfer Protocol (SFTP) is enabled to transfer the firmware file. By default, only secure protocols such as SSH (CLI) and HTTPS (graphic web interface) are activated to establish remote access to S20, and if desired they may be deactivated as well as unused Ethernet ports, leaving only the local USB Serial communication through SSH available.
Design
The flexible design of Reason S20 allows the user to customize each group of 4 ports interfaces to either electrical (RJ45 fixed/SFP) or optical (SFP), Fast Ethernet or Gigabit. In addition, S20 may have a redundant power supply which does not need to be identical to the main one. The power supply options are the full range high voltage 125-250 VDC / 110-240 VAC (50/60 Hz) or the low voltage 24/48 VDC.
Field proven design backed by extensive type testing to ensure the robustness of the S20’s fanless design for harsh substation environments. The EMC and Environmental tests are in accordance with IEC 60255-26, IEC 61850-3 Ed. 2, IEEE 1613 and its extension IEEE 1613.1. Safety requirements are in accordance with IEC 60255-27 and UL 60950-1.
IEC 61850 Networks
The Reason S20 is compliant with IEC 61850 for applications in substations, proven by an extensive type testing to demonstrate the EMC and environment robustness and a functional and performance test report issued by KEMA. The test scope included . The test scope included VLAN function, QoS function for GOOSE messages, network recovery performance (RSTP) and booting time. The Reason S20 UltraRSTP achieves a fault recovery time of less than 5ms per hop, reducing packets loss while maintaining interoperability with others standard RSTP devices. For zero recovery time, S20 is ready for PRP networks schemes.
IEEE 1588v2
Precision Time Protocol (PTP) is defined in the IEEE 1588 standard, which describes the precision clock synchronization protocol for networked measurement and control systems. Reason S20 complies with IEEE1588v2, and can operate either as transparent clock or boundary clock to ensure time accuracy for PTP-aware IEDs in the network. All S20 interface ports may operate as PTP-aware, achieving the nanosecond accuracy given the hardware based implementation. |
