Overview of the Catalyst C9300LM-48U-4Y-1A

The ​​C9300LM-48U-4Y-1A​​ is a ​​48-port Multi-Gigabit Ethernet switch​​ from Cisco’s Catalyst 9300L Series, tailored for enterprises needing high-density connectivity, robust Power over Ethernet (PoE), and seamless scalability. It caters to IoT deployments, smart offices, and environments requiring both data agility and power delivery.

Key Technical Specifications and Innovations

• ​​Port Configuration​​: 48 x 1G/2.5G/5G/10G Multi-Gig RJ45 ports + 4 x 1G/10G SFP+ uplinks for flexible connectivity.
• ​​Power over Ethernet​​: ​​UPOE+ (90W per port)​​ supports high-wattage devices like Wi-Fi 7 APs, PTZ cameras, and industrial sensors.
• ​​Stacking​​: ​​Cisco StackWise-480​​ enables up to 8 switches to operate as a single unit with ​​480 Gbps stacking bandwidth​​.
• ​​Security​​: Integrated with ​​Cisco DNA Center​​ for automated threat detection, encrypted traffic analysis, and zero-trust segmentation.
• ​​Licensing​​: Includes ​​Network Essentials​​ with optional upgrades to ​​Network Advantage​​ for advanced SD-Access and AI-driven features.

Addressing Core User Concerns

“Can It Power High-Demand Devices Across All Ports?”

Yes. The ​​90W UPOE+ per port​​ ensures consistent power delivery even at full capacity, eliminating the need for external injectors when deploying devices like 802.11be access points or digital kiosks.

“How Scalable Is It for Expanding Networks?”

With ​​StackWise-480​​, organizations can add switches incrementally without rearchitecting the network. The ​​10G uplinks​​ provide ample bandwidth for spine-leaf topologies or cloud gateway connectivity.

“Does It Simplify Compliance and Threat Response?”

​​Cisco DNA Center​​ automates policy enforcement and provides end-to-end visibility, while ​​MACsec-256 encryption​​ secures data across all ports. Real-time analytics detect anomalies in encrypted traffic, critical for industries like finance or healthcare.

Why This Model Outperforms Competing Solutions

• ​​Cost Efficiency​​: Consolidates power and data infrastructure, reducing cabling and hardware costs by up to 30%.
• ​​Operational Simplicity​​: Single management interface via Cisco DNA Center streamlines configuration and monitoring.
• ​​Future-Proof Design​​: ​​Multi-Gig ports​​ support legacy 1G devices and modern 10G endpoints, delaying costly upgrades.
