​Technical Specifications​

  • ​Port Configuration​​: ​​48x 10/100/1000BASE-T ports​​ with ​​30W PoE+ per port​​, ideal for ​​IP cameras​​, ​​Wi-Fi 6 access points​​, and ​​digital signage​​.
  • ​Performance​​: ​​160 Gbps per-slot bandwidth​​ and ​​MACsec encryption​​ for secure data transmission.
  • ​Scalability​​: Supports ​​StackWise Virtual​​ for inter-chassis link aggregation, enabling ​​single-pane management​​ across multiple Catalyst 9400 chassis.
  • ​Energy Efficiency​​: ​​Cisco EnergyWise​​ compatibility reduces power consumption during low-usage periods by up to ​​40%​​.

​Compatibility and Requirements​

This line card operates exclusively in ​​Catalyst 9400 Series chassis​​ (e.g., ​​C9407R​​, ​​C9410R​​) with ​​Cisco IOS-XE 17.9 or later​​. It requires ​​dual 2100W AC power supplies​​ to fully utilize its PoE+ capacity. Incompatible with non-PoE line card slots or legacy platforms like the ​​Catalyst 9300​​.

――――――――――――

​Primary Use Cases​

  1. ​Smart Campus Networks​​: Powers ​​thousands of PoE devices​​ in universities, hospitals, or corporate offices.
  2. ​Retail IoT Deployments​​: Connects ​​POS systems​​, ​​smart shelves​​, and ​​security cameras​​ with unified power and data.
  3. ​Industrial Environments​​: Supports ​​OT/IT convergence​​ for sensors and automation controllers in manufacturing plants.

​Strategic Perspective​

The ​​C9400-LC-48P=​​ is a ​​cost-effective solution for scaling PoE+ access layers​​, but its 1G port speeds limit its relevance in bandwidth-intensive scenarios. While perfect for ​​legacy IoT ecosystems​​, organizations planning ​​Wi-Fi 6E/7​​ or ​​AI-driven edge deployments​​ should prioritize MultiGig modules like the ​​C9400-LC-24XY++=​​. Invest in this line card if your focus is ​​simplicity over future-proofing​​—otherwise, balance PoE needs with uplink scalability.
