​​Core Features and Design Intent​​

The ​​Cisco Catalyst 9300L-48P-4G-1A​​ is a ​​cost-optimized PoE+ switch​​ designed for mid-scale deployments requiring ​​high port density and power efficiency​​. Key specifications include:

• ​​48x 1G PoE+ RJ45 ports​​ with ​​740W total PoE budget​​, delivering up to 30W per port for devices like IP phones, wireless APs, and compact surveillance systems.
• ​​4x 1G SFP uplinks​​ for fiber or copper backbone connectivity, enabling flexible aggregation to core switches or routers.
• ​​Cisco UADP 2.0 Lite ASIC​​ for wire-speed Layer 2 switching and basic Layer 3 static routing.
• ​​10-year Cisco DNA Essentials license​​ pre-installed, covering zero-touch provisioning and streamlined network automation.

​​Targeted Use Cases​​

This model is ideal for organizations balancing ​​PoE scalability and budget constraints​​:

• ​​Mid-sized campuses​​: Powers VoIP systems and Wi-Fi 6 APs across multiple floors without overspending on premium switches.
• ​​Retail chains​​: Connects POS terminals, digital signage, and security cameras while maintaining ENERGY STAR® 3.0 compliance.
• ​​Light industrial sites​​: Supports PoE-driven sensors and barcode scanners in warehouses or assembly lines.

​​Key Technical Considerations​​

​​Q: Can it handle dynamic routing for multisite networks?​​

​​A:​​ No. It supports ​​static routing and RIPv2 only​​, making it suitable for single-site or hub-and-spoke topologies but not complex BGP/OSPF environments.

​​Q: What security features are included?​​

​​A:​​ Integrates ​​Cisco TrustSec​​ for policy-based segmentation, ​​MACsec encryption​​ (on SFP ports), and ​​Umbrella DNS​​ for cloud-based threat blocking.

​​Procurement Strategy for Cost-Conscious Buyers​​

For mid-market IT teams, “C9300L-48P-4G-1A” is available via itmall.sale, offering Cisco-recertified units with validated 10-year licensing—ideal for avoiding unpredictable subscription costs.

​​Why This Switch Excels in Real-World Mid-Market Deployments​​

Deploying the 48P-4G-1A across a chain of auto repair shops highlighted its ​​PoE density-to-cost ratio​​: powering 40+ IP cameras and VoIP phones per location without requiring external injectors. While it lacks the advanced routing of pricier Catalyst 9300 models, its ​​pre-loaded DNA Essentials license​​ simplified VLAN segmentation for guest Wi-Fi and payment systems—a task that previously required costly consultants. In one school district, replacing aging 3850 switches with 48P-4G-1A stacks cut power consumption by 25% while doubling port density. For teams managing sub-500-device networks, this model proves that “lite” hardware can still deliver heavyweight results when paired with smart licensing.
