Cisco Expansion Module – 48-Port UPoE Data Networking Expansion

The Cisco Expansion Module is a high-density, plug‑in solution engineered to scale enterprise and data center networks with unparalleled port versatility. Designed to slot into compatible Cisco switch chassis, this module delivers 36 RJ-45 10/100/1000Base-T UPoE ports alongside 12 RJ-45 10GBase-T UPoE ports, creating a unified, scalable Ethernet fabric that supports both traditional Gigabit access and high‑speed 10 Gigabit uplinks. With UPoE on every port, it’s capable of delivering power alongside data to a wide array of networked devices, including IP phones, wireless APs, cameras, and other PoE-enabled endpoints, all while preserving a streamlined management experience. This module is ideal for campus networks, branch offices, data centers, and edge deployments where dense port capacity and reliable power delivery are critical for performance and user experience.

• High-density port assortment: 36 x RJ-45 10/100/1000Base-T UPoE LAN ports plus 12 x RJ-45 10GBase-T UPoE LAN ports, enabling a single module to handle both legacy and next‑gen Ethernet devices within a compact footprint. This composition supports large-scale deployments without sacrificing port flexibility, making it easier to connect users, phones, cameras, access points, and uplinks to a centralized switching fabric.
• Universal Power over Ethernet on every port: UPoE-enabled ports deliver power where it’s needed, simplifying the deployment of powered devices (PDs) across the network. By provisioning power through the same copper Ethernet cables as data, the module reduces the need for separate power drops, lowers total cost of ownership, and helps maintain a tidy, scalable cabling environment in offices and data centers.
• Flexible data speeds and layer compatibility: Support for multi-rate Gigabit Ethernet on 36 ports and 10GBASE-T on 12 ports ensures compatibility with a wide range of devices and workloads. Whether you’re streaming video, running IP telephony, or aggregating high‑bandwidth servers, the module offers robust performance while maintaining compatibility with existing 10/100/1000Base-T and 10GBASE-T ecosystems.
• Enterprise-grade reliability and integration: Engineered for stable operation within Cisco data networking ecosystems, the expansion module integrates with Cisco management tools and security features, enabling centralized monitoring, configuration, and policy enforcement. It is designed for enterprise environments that require predictable performance, scalable growth, and straightforward administration.
• Future-ready flexibility and deployment simplicity: This module is built to complement growing networks, enabling seamless expansion as business needs evolve. Its modular design supports straightforward installation, streamlined cabling, and cohesive management, helping organizations maximize return on investment while maintaining network agility and resilience.

how to install Cisco Expansion Module

• Verify compatibility: Confirm that your Cisco switch chassis supports expansion modules and UPoE functionality, and identify the proper slot for installation according to Cisco deployment guidelines.
• Power and environmental readiness: Ensure the chassis and rack space meet power, cooling, and physical placement requirements. Confirm that the switch is in a maintenance window or approved downtime if required by your organization’s change management policy.
• Power down or prepare for hot insertion: Depending on the chassis and model, follow Cisco’s official instructions for safe module installation. If hot-swappable operation is supported for your hardware, ensure you have authorizations to perform a live insertion in a maintenance window.
• Insert the module: Align the module with the chassis slot and firmly push until it seats securely. Verify that connectors engage properly and that the module is locked into place per the chassis design.
• Connect cabling and configure: Attach the appropriate RJ-45 network cables to the 36 Gigabit ports and 12 10G ports as required by your network design. Power on the system (if not already on) and access the Cisco management interface to perform initial configuration, including port profiles, VLANs, PoE settings, and security policies.
• Validation and monitoring: After installation, verify LED indicators on the module and switch to confirm healthy operation. Run connectivity tests for both Gigabit and 10G ports, confirm PoE provisioning across UPoE ports, and monitor performance through Cisco management tools to ensure stable operation.
