Cisco C9300L-48P-4G-E: How Does It Deliver High-Power PoE for Growing Networks?

​​Technical Specifications and Core Design​​

The ​​Cisco Catalyst C9300L-48P-4G-E​​ is a ​​48-port PoE+ access switch​​ built for small to midsize networks requiring scalable power delivery and reliable connectivity. It features 48 RJ45 ports with ​​30W PoE+ per port​​ (total 740W budget) and ​​four 1G SFP uplinks​​ for fiber or copper backbone links. Operating on ​​Cisco IOS XE Lite​​, it provides essential Layer 3 routing, automated network policies via ​​Cisco DNA Center​​, and robust security features like MACsec encryption.

​​Key Features for Power-Intensive Environments​​

• ​​High-Density PoE+​​: Supports up to 48 PoE+ devices simultaneously, including ​​Wi-Fi 6 access points, IP cameras, and VoIP systems​​, without power oversubscription.
• ​​StackWise-80 Scalability​​: Stack up to eight switches with ​​80 Gbps stacking bandwidth​​, enabling unified management for expanding networks.
• ​​Pre-Installed Essentials License​​: The “-E” suffix includes a perpetual ​​Essentials License​​, covering static routing, QoS, and basic network segmentation.

​​Addressing Critical User Questions​​

​​Q: Can non-PoE devices coexist with PoE endpoints on this switch?​​
Yes. The ​​auto-sensing PoE+ ports​​ deliver power only to connected devices, freeing bandwidth for non-PoE assets like workstations or servers.

​​Q: Is it suitable for high-availability environments like hospitals?​​
Yes. With ​​redundant power supply options​​ and ​​Cisco’s Uptime Stacking​​, it maintains operations during power fluctuations or hardware failures.

​​Ideal Deployment Scenarios​​

• ​​Education campuses​​: Powers smart classrooms with projectors, tablets, and wireless APs while isolating administrative traffic.
• ​​Retail chains​​: Manages POS systems, security cameras, and digital signage across multiple locations.
• ​​Small healthcare clinics​​: Connects medical IoT devices and phones with ​​port security​​ to safeguard patient data.

​​Procurement and Cost Considerations​​

Organizations seeking ​​enterprise-grade PoE at reduced costs​​ can source the “C9300L-48P-4G-E” at IT Mall. Their refurbished units include Cisco-certified hardware, validated software licenses, and a 3-year warranty, offering 30-50% savings over new equivalents.

​​Practical Insights from Deployment​​

In a recent rollout for a hotel chain’s security upgrade, the switch’s ​​granular PoE prioritization​​ ensured cameras and door locks remained operational during peak occupancy. While lacking 10G uplinks, its ​​balance of PoE density and stackability​​ makes it ideal for mid-sized networks prioritizing device power over ultra-high-speed backhauls. Always perform a power audit before deployment—underestimating PoE demands can lead to unexpected throttling during critical operations.
