Cisco CGS-2520-24TC Connected Grid Switch

The Cisco CGS-2520-24TC Connected Grid Switch is a rugged, enterprise-grade Ethernet switch purpose-built for transmission and distribution substations. Built to operate reliably in harsh utility environments, this switch runs Cisco IOS Software, delivering familiar configuration workflows, robust security, and advanced traffic management for critical grid applications. The CGS-2520-24TC is designed to withstand electrical noise, temperature extremes, and vibration typical of substation sites, while providing predictable, low-latency performance for I/O devices, protection relays, and gateway endpoints. By combining rugged hardware with Cisco’s mature software ecosystem, this switch enables centralized control, policy enforcement, and scalable networking across distributed energy networks, ensuring uptime and secure connectivity for essential grid operations.

• Rugged, industrial-grade design for substation environments: Engineered to tolerate EMI, dust, vibration, and temperature swings common in transmission and distribution facilities, the CGS-2520-24TC delivers reliable performance where conventional switches may fail. Its durable chassis and protected connectors help utilities maintain continuous communications in outdoor enclosures and challenging indoor spaces.
• 24 copper Ethernet ports for scalable field connectivity: The switch provides ample, shielded 10/100/1000 Mbps copper interfaces to connect field devices, terminal blocks, meters, RTUs, and protection relays. The port density supports dense substation networks, enabling granular segmentation and reliable device-to-network communications without resorting to external hubs or adapters.
• Cisco IOS Software for enterprise-grade management: With Cisco IOS Software as the operating system, administrators gain access to well-known CLI, secure management protocols, and a broad set of features such as VLANs, Access Control Lists, Quality of Service, and robust authentication. The familiar software foundation accelerates deployment, simplifies ongoing maintenance, and provides a consistent experience alongside other Cisco devices in the network.
• Flexible topology, scalable growth, and secure connectivity: Designed to integrate with existing fiber and copper backbones, the CGS-2520-24TC supports layered network architectures that accommodate expanding grid layouts. Its management features enable policy-based automation, traffic prioritization for critical control channels, and secure remote access to streamline operations across remote substations and field sites.
• Secure remote management for resilient grid operations: The switch offers strong security capabilities and centralized management options that utilities rely on to enforce access controls, monitor device health, and rapidly respond to events. By enabling encrypted management sessions and granular policies, it helps minimize cyber risk while ensuring dependable, auditable network performance for protective relays, SCADA interfaces, and smart grid devices.

How to install Cisco CGS-2520-24TC Connected Grid Switch

• Plan the deployment in a secure cabinet or 19-inch rack, ensuring proper ventilation and clearance for heat dissipation. Confirm compatibility with your substation enclosure and mounting standards before installation.
• Mount the CGS-2520-24TC in the selected rack or enclosure using standard mounting hardware. Verify that connectors and ports are accessible for practical cable routing and maintenance, with attention to clean cabling practices to minimize EMI and cross-talk.
• Connect the switch to power and verify that power indicators illuminate as expected. If a redundant or alternative power source is available, configure it according to your substation’s power architecture and safety requirements.
• Establish initial network connectivity by wiring the 24 copper Ethernet ports to your field devices, relays, meters, and edge gateways. Leave adequate spacing for airflow and route cables to prevent strain on connectors.
• Access the switch’s management interface via the console or IP-based CLI/web interface, configure essential settings such as management IP address, VLANs, port security, and QoS policies, and apply any required security hardening. Save the configuration and validate connectivity by testing device reachability and latency across critical control channels.
