C9300-48P-A=: How Does Cisco’s High-Capacity PoE Switch Meet Enterprise Scalability Demands?

​​Introduction to the Cisco Catalyst C9300-48P-A=​​

The ​​Cisco Catalyst C9300-48P-A=​​ is a high-density Layer 3 switch designed for enterprises requiring ​​massive Power over Ethernet (PoE)​​ scalability and advanced automation. Part of the Catalyst 9300 series, it targets campuses, IoT hubs, and environments demanding simultaneous support for hundreds of connected devices, from Wi-Fi 6 APs to IP surveillance systems.

​​Core Technical Specifications​​

• ​​48x PoE+ Ports​​: Delivers ​​30W per port​​ (802.3at) with a total PoE budget of ​​1,140W​​, sufficient for high-density deployments.
• ​​4x40G QSFP+ Uplinks​​: Supports high-speed stacking via ​​Cisco StackWise-480​​ (480 Gbps) or backbone connectivity for data-intensive workloads.
• ​​Cisco DNA Premier Licensing​​: Includes ​​AI-driven network insights​​, ​​SD-Access segmentation​​, and ​​encrypted traffic analytics (ETA)​​.
• ​​Energy Efficiency​​: Operates with ​​Cisco EnergyWise​​ technology, reducing power consumption by up to 25% compared to older models.

​​Addressing Critical User Questions​​

​​Q: Can the 48P-A= Support UPOE for 90W Devices?​​

No. The “48P” designation indicates ​​PoE+ (30W per port)​​. For ​​UPOE (90W)​​, consider the ​​C9300-48U-A​​ model.

​​Q: How Does It Compare to the C9300-24P-10E?​​

• ​​Port Density​​: Double the PoE ports (48 vs. 24) for large-scale IoT or digital classroom setups.
• ​​Licensing Tier​​: DNA Premier (included with “-A=”) offers ​​multi-domain management​​ and ​​predictive analytics​​, unlike DNA Essentials in the “10E” model.
• ​​Uplink Speed​​: 40G QSFP+ vs. 10G SFP+ in the 24P-10E.

​​Licensing and Advanced Features​​

The ​​“-A=” suffix​​ signifies ​​DNA Premier licensing​​, providing:

• ​​Cisco Stealthwatch integration​​ for real-time threat visibility.
• ​​Application Experience Assurance​​ to prioritize critical traffic.
• ​​Lifetime hardware warranty​​ with 24/7 Cisco TAC support.
  No additional licenses are required for full SD-Access or automated policy enforcement.
