2 Product Scope
GE Reason Switches are managed switches with modular communication interfaces
designed for harsh environment environments, such as power systems and industry
applications. Developed to be used in IEC 61850 networks, Reason Switches provide
flexibility, reliability and robustness in IED interconnections. Precision timing
synchronization of the IEDs can be obtained using the IEEE 1588 v2 protocol (PTP).
For IEC 61850 network applications, Reason Switches are able to perform traffic
isolation of Sampled Values (IEC 61850-9-2LE), GOOSE messages, PTP synchronizing
protocol and other messages using virtual LANs (VLANs). Switch traffic and ports
monitoring is performed using the SNMP protocol, and loop-based topologies, such
as ring topology, can be monitored and reconfigured using the RSTP (IEEE 802.1D)
protocol.
Packet switched transmission in the switches is totally done by hardware, which
ensures agility and maximum reliability even when interconnecting IEDs to distinct
interfaces and speeds.
The switches configuration may be done through interactive mode of text
commands (SSH and Telnet) or in a friendly graphic environment (HTTP or HTTPS) with
native or remote authentication (RADIUS and ). Statistical data collection
can be obtained using SNMP v2/v3 protocol. Communication interfaces are the
Ethernet port or a dedicated USB-2.0 port.
Critical applications can benefit from the optional redundant power supply for even
greater uptime and reliability. A dry-contact relay is available in Reason Switches to
indicate a failsafe alarm to the supervisory system when an interface communication
becomes unavailable or the equipment is missing of its power supplies.
