Core Features and Hardware Design

The ​​Cisco Catalyst 9300L-48P-4X-E​​ is a ​​48-port PoE+ Layer 3 switch​​ with ​​4x 10G SFP+ uplinks​​, designed for environments requiring simultaneous high-speed connectivity and device power delivery. Built on Cisco’s modular architecture, it supports ​​Cisco IOS XE​​ for advanced programmability and supports ​​StackWise-320​​ for scalable deployments.

PoE+ Capabilities and Power Efficiency

• ​​740W Total PoE Budget​​: Powers ​​48 devices​​ (e.g., IP cameras, wireless APs, VoIP phones) with ​​30W per port​​ (IEEE 802.3at/af compliance).
• ​​EnergyWise Integration​​: Dynamically allocates power based on device priority, reducing energy waste.

Performance and Scalability

• ​​Switching Capacity​​: 116 Gbps throughput ensures smooth handling of traffic from PoE devices and uplinks.
• ​​Stacking Flexibility​​: Combine up to 8 units via StackWise-320, creating a unified system with ​​640 Gbps backplane bandwidth​​.

Security and Network Visibility

• ​​Encrypted Traffic Analytics (ETA)​​: Detects malware in encrypted streams without decryption delays.
• ​​Cisco DNA Advantage License​​: Includes ​​Software-Defined Access (SD-Access)​​ for automated segmentation and policy enforcement.

Deployment Scenarios

Ideal for ​​high-density PoE environments​​ like schools, hospitals, or smart buildings, the C9300L-48P-4X-E eliminates the need for separate power injectors. Its ​​fanless design​​ (for specific SKUs) suits noise-sensitive areas like clinics or offices.

Licensing and Warranty Considerations

• ​​Subscription Model​​: Requires Cisco DNA Essentials or Advantage licenses for advanced features.
• ​​Lifetime Hardware Warranty​​: Cisco covers hardware replacements, ensuring long-term reliability.

Cost vs. Value Analysis

While upfront costs are higher than non-PoE switches, the ​​C9300L-48P-4X-E​​ reduces infrastructure complexity by consolidating power and data delivery. For future-proofing, its ​​10G uplinks​​ and ​​40G-ready expandability​​ prevent bottlenecks in growing networks.

Practical Experience

Having deployed this switch in a university campus with 200+ IP phones and surveillance cameras, the ​​zero power-overload incidents​​ and seamless VoIP performance stood out. The ​​CLI consistency​​ with older Catalyst models also streamlined training for existing IT teams, making transitions frictionless.
