​​Key Technical Specifications​​

The Cisco Catalyst C9300L-48PF-4X-1E is a ​​48-port PoE+ Layer 3 switch​​ designed for high-density deployments requiring robust power and data delivery. It features ​​48x RJ45 ports​​ with ​​740W total PoE+ budget​​ (30W per port) and ​​4x 10G SFP+ uplinks​​, enabling high-speed backbone connectivity. Built on Cisco’s ​​DNA architecture​​, it supports ​​SD-Access​​ for automated network segmentation and ​​Cisco Umbrella​​ for cloud-delivered security.

With ​​480 Gbps switching capacity​​ and ​​Multi-Gigabit Ethernet support​​ (up to 5Gbps on select ports), this switch handles bandwidth-intensive applications like 4K video streaming and industrial IoT sensor networks.

​​Primary Use Cases and Industry Applications​​

This model excels in ​​enterprise campuses​​, ​​retail chains​​, and ​​smart warehouses​​ where high-power PoE devices like access points, digital signage, and RFID readers are prevalent. Its ​​front-to-back airflow design​​ ensures efficient cooling in densely packed racks, while ​​EnergyWise integration​​ allows real-time power consumption monitoring.

​​Resolving Critical Deployment Concerns​​

• ​​Q: Can the switch support high-wattage devices like PTZ cameras and wireless APs simultaneously?​​
  Yes—the ​​740W PoE+ budget​​ powers up to 24x 30W devices (e.g., Cisco 9120 AX APs) or 48x 15.4W endpoints (e.g., VoIP phones) without external power supplies.

• ​​Q: How does it enhance network reliability?​​
  ​​StackWise-480 technology​​ allows stacking up to eight switches as a single logical unit, providing redundancy and simplified management.

• ​​Q: Is it compliant with modern security standards?​​
  Integrated ​​Cisco ISE​​ and ​​MACsec encryption​​ ensure secure device authentication and data protection, meeting GDPR and HIPAA requirements.

​​Licensing and Procurement Options​​

The C9300L-48PF-4X-1E includes ​​Cisco DNA Essentials​​ for basic automation and ​​limited lifetime hardware warranty​​. For organizations needing advanced analytics, ​​DNA Advantage​​ subscriptions are available. Explore pricing and availability at the “C9300L-48PF-4X-1E” product listing.

​​Why This Switch Is a Strategic Investment​​

Having analyzed its PoE scalability and security frameworks, the C9300L-48PF-4X-1E eliminates the need for separate power injectors and standalone security appliances. For IT managers balancing cost and performance, its ability to consolidate infrastructure while supporting future IoT expansions positions it as a long-term solution—especially in industries where uninterrupted power and data integrity directly impact operational continuity.
