Product Overview

Q.    What is the Cisco ® 2010 Connected Grid Router (CGR 2010)?
A.     The Cisco CGR 2010 is a rugged router designed for the harsh, rugged environments often found in the energy and utility industries. The Cisco CGR 2010 is designed to support the communications infrastructure needs for the energy delivery infrastructure across the generation, transmission, and distribution sectors. This infrastructure includes utility- and customer-owned energy infrastructure, such as substation applications supporting electrical transmission and distribution, renewable generation, oil and gas, water, distributed generation, co-generation, and trackside operations. The infrastructure also includes communications infrastructure for delivery applications such as transmission pipelines, distribution mains, and service lines for oil and gas and water. The CGR 2010 is part of the Cisco Connected Grid portfolio of products compliant with substation industry standards known as IEEE 1613 and IEC 61850. The CGR 2010 is a modular router supporting Grid Router WAN Interface Cards (GRWICs). For detailed product information about the Cisco CGR 2010, visit
Q.    What other products are included in the Cisco Connected Grid portfolio?
A.     In addition to the Cisco 2010 Connected Grid Router (CGR 2010), the Cisco 2520 Connected Grid Switch (CGS 2520) is also a new platform in the Connected Grid portfolio. It is designed for use in energy applications. For more information on the Cisco CGS 2520, please visit
Q.    What are the IEEE 1613 and IEC 61850-3 standards?
A.     Both the IEC and IEEE have developed and issued new standards addressing Electromagnetic Interference (EMI) requirements for communications networking equipment. Both groups borrowed heavily from the respective standards used for protective relaying devices, which are critical devices used for protection and control of the power system. Since more and more protection relays are using frame-based Ethernet network connectivity for the purpose of protection relaying, it was only natural that the communications also be made to comply with the same EMI, Electrostatic Discharge (ESD), and Radio Frequency Interference (RFI) immunity requirements.

   IEEE 1613—IEEE Standard Environmental and Testing Requirements for Communications Networking Devices in Electric Power Substations

   IEC 61850-3 Communications Systems and Networks in Substations


In both cases the standards have a minimum requirement that the networking equipment operate without any physical damage, reset, or latch-up during the application of a variety of normally-destructive EMI immunity-type tests.
IEC 61850 consists of 10 parts that provide a comprehensive set of standards for communications networks in substations. It includes everything from environmental and EMI immunity requirements (IEC 61850-3) to conformance testing (IEC 61850-10).

The IEEE 1613 was also developed as a standard to address the proliferation of Ethernet networks in substation automation. Released in August of 2003, the IEEE 1613 IEEE Standard Environmental and Testing Requirements for Communications Networking Devices in Electric Power Substations addresses the environmental and performance requirements in networking equipment in substation environments. The majority of the specification was adopted from the IEEE C37.90.x standards for protective relaying systems.
Q.    Does the CGR 2010 meet the IEC 61850 standard?
A.     The IEC 61850 protocol provides a standard way to communicate between devices inside the substation, i.e. intra-substation communications. The CGR 2010 meets or exceeds IEC 61850-3, which includes the environmental requirements for substation communications gear.
One of the protocols in IEC 61850 used to communicate between protection relays is Generic Object Oriented Substation Event, or GOOSE protocol. This protocol is used for intra-substation communications. Addendums to the 61850 standard are in process to document GOOSE messaging over the WAN.
Q.    How did Cisco certify the CGR 2010 to IEEE 1613 and IEC-61850-3 compliance standards?
A.     Both the CGR 2010 Connected Grid Router and the CGS 2520 Connected Grid Switch have been certified by Cisco’s compliance organization as well as KEMA, an international energy-consulting firm with a specialty in testing and certifications. Certificates will be made available to customers with valid non-disclosure agreements (NDAs) upon request.
Q.    What are some primary features of the CGR 2010?
A.     The CGR 2010 provides the utility with a highly secure substation network, which serves as the electronic security perimeter (ESP) for the substation. Utilities must comply with security mandates known as the NERC/CIP (North American Electric Reliability Corporation/Critical Infrastructure Protection). The CGR 2010 helps utilities converge disparate networks onto a common network infrastructure using Multiprotocol Label Switching VPN (MPLS-VPN) and VPN Routing and Forwarding (VRF). Also, the CGR 2010 is a multi-service platform with a comprehensive quality of service (QoS) feature set that helps prioritize substation control communications over other types of data (e.g., video, voice, and enterprise traffic). In addition, the CGR 2010 supports dual-redundant, hot-swap power supplies, which can also be used with the Cisco 2500 Series Connected Grid Switch. Finally, the CGR 2010 is a modular platform that supports Grid Router WAN Interface Card (GRWIC) slots that will allow customers to upgrade the platform over time to meet their networking requirements.
Q.    What configuration options are available for the CGR 2010?
A.     Table 1 shows the list of CGR 2010 options.
