SEL-5056

Network Management System (NMS)

The SEL-5056 Network Management System (NMS) provides a single controller for system-level network configuration, management, and telemetry monitoring for critical infrastructure. The SEL-5056 NMS simplifies SDN-enabled switch provisioning by automatically configuring networks using network drawings, IEC 61850 SCD files, and SEL RTAC connection services files. It works collectively with SEL Operational Technology (OT) Software-Defined Networking (SDN) switches to provide a complete deny-by-default engineering solution for Ethernet-based LANs. Traffic engineering with the SEL-5056 NMS simplifies end-to-end provisioning and offers the ability to proactively design fault-tolerant networks, resulting in greater performance, improved reliability, and highly deterministic packet delivery. With the SEL-5056 NMS, you can manage multiple networks and centrally manage network changes from a single, modern interface streamlined for effortless navigation and enhanced situational awareness and control. Running as a Microsoft Windows service or as an embedded application on the SEL Blueframe platform, the NMS makes scaling to large networks easy and efficient.

Configure Applications and Endpoints

—Define and deploy host communication profiles using applications and application endpoints. This allows you to utilize common network designs and services for multiple networks and to manage your network functions uniformly and efficiently.

Simplify Network Engineering

—Eliminate repetitive network engineering tasks by using your Microsoft Visio network drawings or IEC 61850/RTAC files to automatically provision your network. Save time, reduce the chance of input errors, and ensure alignment between relay and network communication settings while validating drawing accuracy.

Easily Navigate the Modernized Topology Space

—Quickly perform network changes using a feature-rich user interface that helps you understand your actions within the context of the larger system. Streamlined information management connects workflow steps and clearly highlights statuses, easing your analytical workload.

Manage Multiple Networks Simultaneously

—Design the system architecture that best fits your facilities and procedures. Simplify complex environments and improve network scalability with centralized management, while maintaining precise control over individual communication circuits.

Create Stronger Network Security

—Define exactly what can occur on your network with a deny-by-default architecture. Provision circuits using network access control that extends from Layer 1 through Layer 4 of the packet, giving you context-aware control of conversations between devices. SDN makes systems more cybersecure by eliminating attack-prone networking features, like flood to learn, unsecure control plane, and broadcast domains.

Improve Failover Performance

—Proactively traffic-engineer your network, bringing more precision and predictability to critical infrastructure networks and improving failover times to less than 1 ms to support even the most demanding real-time control signals.

Streamline NERC CIP Data Collection

—Use the SEL-5056 NMS to automate reporting of NERC CIP-007-6 R1.1—Systems Security Management, Ports, and Services.

Reduce Downtime for Configuration

—Configure the SEL-5056 NMS in the field with connected IEDs or offline in a lab. With 100% offline design, configuration, testing, validation, and baselining capabilities, the NMS streamlines deployment and minimizes field installation downtime.

Manage Network Scalability and Change Management

—Manage all network changes without affecting existing services and applications. All network additions and changes can be configured centrally and pushed out to configure the network of SEL OT SDN Ethernet switches.

Programmatically Test and Validate Your Network

—Reduce deployment timelines and eliminate guess work in testing scope by knowing exactly what communication circuits your network is configured to support and that all other conversations will be dropped with deny-by-default network access control. This results in a defined test scope and predictable and consistent network validation. You have confidence your network will perform exactly how you engineered it for as long as it is in service.
