Product Overview The RuggedCom RS950G is an IEC 62439-3 PRP and HSR redundancy box (RedBox).

The latest redundancy protocols specified in IEC 62439-3, high-availability seamless ring (HSR) and parallel redundancy protocol (PRP), ensure zero-millisecond failover operation.

1 Product Overview The RuggedCom RS950G is an IEC PRP and HSR redundancy box (RedBox). The RS950G provides the ultimate in network reliability with Zero-Packet-Loss and zero failover time from any network fault. The latest redundancy protocols specified in IEC , high-availability seamless ring (HSR) and parallel redundancy protocol (PRP), ensure zero-millisecond failover operation. This is achieved by simultaneously transmitting duplicate packets on independent routes through the network to provide complete path redundancy. In PRP and HSR networks the receiving nodes eliminate any redundant packets resulting in a truly seamless failover mechanism that is not compromised by switch, cable or transient failure. Features: Reliability: IEC PRP and HSR Guaranteed behavior under failure conditions High availability network using simultaneous transmission over two Ethernet ports Efficient elimination of duplicated packets at hardware level Zero millisecond recovery time from network failures Reserved bandwidth for critical and time-sensitive messages to guarantee delivery Zero-Packet-Loss provides 100% packet retention Performance: FPGA implementation maximizes PRP and HSR performance Wire-speed gigabit throughput with cut-through switching to minimize latency and jitter Built-in state of the art QoS engine enables guaranteed throughput and guaranteed packet delivery for user defined high priority traffic 8 Class of Service queues for QoS prioritization Flexible packet classification and traffic shaping engine with interruption of low priority packets Predictable Ethernet behaviour even in congested networks Substation Rated : Meets IEC and IEEE 1613 standard -40 C to +85 C operating temperature range Industrial Design: Panel or DIN mounting Dual voltage inputs 20 AWG steel enclosure Support and Service: 5 Year Warranty Global 24x7x365 Support Management: RADIUS or TACACS user authentication SSH/SSL encryption Web-based, Telnet, CLI, SNMP, RMON

3 RS950G with IEC High Reliability Applications Figure 1. Interface on HSR network sends duplicate packets in opposite directions. Using cut-through switching, high priority packets are moved through the HSR network to the receiving node with minimal latency. Duplicate packets are removed from network by the receiving node. Figure 2. Unlike other Ethernet ring protocols, HSR is not limited to single ring architecture. With Quad-box mode of operation, multiple inter-ring communications can be set-up to increase the scale of the network and maintain complete redundancy.

RS950G with IEC 62439 High Reliability Applications Figure 3. Both reliability and precision timing are critical in High Availability Networks that control process automation.

4 RS950G with IEC High Reliability Applications Figure 3. Both reliability and precision timing are critical in High Availability Networks that control process automation. The RS950G with IEEE 1588 v2 transparent clock is capable of 1us accuracy. Multicast IEEE 1588 v2 timing packets are handled as high priority to ensure accuracy and eliminate timing jitter. Figure 4. For High Availability Networks that require redundant, parallel physical and layer 2 hardware, the RS950G and RuggedNet devices can be used in PRP mode. Similar to HSR, duplicate packets are generated by the sending node and removed at the receiving node as required. With PRP, singly attached nodes can be part of the network.

6 ROS Features All RuggedCom managed switches come with embedded Rugged Operating System (ROS ) software to provide a rich set of features to connect intelligent substation devices on IEC networks. ROS based switches are built on the latest networking and security standards to integrate seamlessly with the enterprise LAN architectures and meet corporate policies. High availability Seamless Redundancy (HSR) and Parallel Redundancy Protocol (PRP) The RuggedCom RS950G is compliant with both IEC HSR and PRP. The RS950G generates duplicate packets and transmits them on independent paths on the HSR or PRP rings, providing complete redundancy for network or device faults that could interrupt the continued operation. If both paths remain intact and the receiving node receives duplicate packets, the RS950G ensures the duplicate packets are removed and taken out of circulation. Nodes in the HSR ring that are neither transmit nor receive nodes circulate the packets to keep the loop closed. The RS950G permits connection of singly attached nodes to the HSR or PRP networks. The RS950G operating in Quad-box mode is used to interconnect multiple HSR or PRP rings together allowing more design options and increased scalability of the network. IEEE 1588 v2 Support ROS supports IEEE 1588 v2 with hardware time stamping on all ports to provide a high level of accuracy. Transparent clock operation allows for high precision on switched networks eliminating the accumulations switch jitter errors. Support for peer-to-peer or end-to-end path delay measurements. Network Security Network security is a key requirement in any industry where advanced automation and communications networks play a crucial role in mission critical applications. ROS provides fundamental security features to address the various industry specific security standards such as NERC CIP, ISA S99, AGA 12, IEC 62443, ISO 17799:2005 and PCSRF SPP-ICS. Quality of Service (IEEE 802.1p) Real-time control and monitoring applications require predictable arrival times for Ethernet frames. Switches can introduce latency in times of heavy network traffic due to internal queues that buffer frames and transmit on a first in first out basis. ROS supports QoS in accordance with IEEE 802.1p to push high priority traffic to the front of the queue, minimizing latency and reducing jitter. ROS allows priority classification by port, tags, MAC address and IP type of service (TOS). A configurable weighted fair queuing algorithm controls how frames are emptied from the queues. VLAN (IEEE 802.1q) ROS supports 802.1q tagged Ethernet frames and VLAN trunks to allow a single physical network to be segregated into multiple logical networks with independent broadcast domains. Limiting host traffic to specific VLANs provides added security and isolates traffic storms. Port based classification allows legacy devices to be assigned to the correct VLAN. GVRP support simplifies VLAN configuration on the switches. SNMP v1/v2/v3 (Simple Network Management Protocol) SNMP provides a standard method for network management systems, (NMS) to remotely manage devices. SNMP version 3 secures the connection with authentication, privacy, and access control. ROS also supports numerous standard MIBs (Management Information Base) allowing for easy integration with any NMS. ROS products can be configured to generate SNMP traps on system events to proactively advise the NMS about system conditions that could require attention. RuggedNMS is RuggedCom s network management systems that provides a graphical representation of the network and is fully integrated with all ROS products ROS security features: Multi-level passwords provides user privileges and controls configuration access SSH / SSL encryption prevents clear text transmission of passwords Port enable/disable capability to lock-down unused ports 802.1q VLAN to provide logical traffic segregation between predefined ports MAC Based port authentication allows access only to devices known by the switch SNMPv3 provides authentication and encryption for management through SNMP based network management systems

7 ROS Features SNTP (Simple Network Time Protocol) ROS devices can contact an SNTP server on the network to automatically synchronize the internal clock and also act as SNTP servers to other devices. Time synchronization allows for correlation of time stamped events for sequence of event recording. Port Statistics and RMON (Remote Monitoring) ROS provides real time in and out packet and byte counters as well as detailed error figures per port. Full Remote Monitoring support is provided with RMON statistics, history, alarms, and event groups. RMON allows for sophisticated data collection, analysis and detection of traffic patterns. SCADA and Industrial Automation ROS contains features that optimize network performance and simplify switch management based on the unique requirements found in SCADA and industrial automation applications. Features such as Modbus TCP management for retrieval of switch data using the ubiquitous Modbus protocol and DHCP Option 82, a Rockwell Automation ODVA requirement for IP address assignment based on the location of the end device. ROS products provide capabilities not found in typical commercial or office grade Ethernet switches. Port Rate Limiting ROS supports rate limiting per port to allow full configuration of unicast and multicast traffic rates. This ensures single devices cannot monopolize the available network bandwidth and provides security on the edge against denial of service (DOS) attacks. Broadcast Storm Filtering Broadcast storms create problems that could be disastrous on a network running mission critical applications. ROS limits the damaging effects of network congestion and device overload caused by broadcast storms by filtering broadcast frames with user-defined thresholds. Loss of Link Management Many intelligent electronic devices (IEDs) have dual fiber optic ports with automatic failover. ROS ensures this mechanism works reliably under all failure modes by appropriately disabling link signals when failover occurs. ROS also flushes learned MAC addresses to ensure rapid failover. Port Configuration and Status ROS allows individual ports to be hard configured for speed, duplex, auto-negotiation, flow control etc. This allows ROS devices to connect with devices that do not autonegotiate or have unusual settings. ROS provides detailed port status will generate alarm and SNMP trap messages when link problems occur to aid in system troubleshooting. Event Logging and Alarms Events and Alarms provide a means to alert the network manager about conditions and record them for later analysis. Non-critical or Alert level Alarms can be user configured to control their output behavior. ROS can record configured events to a non-volatile system log for forensic troubleshooting. Events include link failure and recovery, unauthorized access, broadcast storm detection, and selftest diagnostics among others. Alarms provide a snapshot of recent events for the network administrator to acknowledge. Critical alarms can trip the Fail-Safe allowing an external controller to monitor the device. HTML Web Browser and Telnet User Interfaces ROS provides a simple, intuitive user interface for configuration and monitoring via Telnet or a graphical user interface accessed via a standard web browser. All system parameters include detailed on-line help to ease setup. All ROS devices have a common look and feel and standardized configuration process allowing easy migration to other RuggedCom managed products. Configuration via ASCII Text File All configuration parameters are stored in an ASCII formatted text file that can easily be transferred via TFTP or SFTP. The configuration file can be saved for backup purposes and easily manipulated by a text editor. The same text file can be downloaded to the switch at a later date in order to re-configure or restore a previous configuration. Command Line Interface (CLI) A command line interface can be used in conjunction with remote shell to automate data retrieval, configuration updates, and firmware upgrades. A powerful SQL-like capability allows expert users the ability to selectively retrieve or manipulate any parameters the device has to offer.
