​​Introduction to the Cisco Catalyst C9300-48H-A​​

The ​​Cisco Catalyst C9300-48H-A​​ is a high-density Layer 3 switch engineered for hyperscale enterprise networks, data centers, and environments requiring ​​massive port density​​ alongside advanced automation. Part of the Catalyst 9300 series, it addresses the growing need for scalability, security, and multi-gigabit readiness in bandwidth-intensive applications.

​​Core Technical Specifications​​

• ​​48x Multigigabit Ports​​: Supports ​​1G/2.5G/5G/10G speeds​​ on copper, ideal for high-density Wi-Fi 6/6E APs, IoT clusters, and workstation farms.
• ​​12x40G/100G QSFP28 Uplinks​​: Delivers hyperscale backbone connectivity or stacking via ​​Cisco StackWise-1.6T​​, offering ​​1.6 Tbps stacking bandwidth​​.
• ​​Cisco DNA Premier Licensing​​: Bundles ​​AI-driven network optimization​​, ​​encrypted traffic analytics (ETA)​​, and ​​SD-Access segmentation​​.
• ​​UPOE+ Support​​: Provides ​​90W per port​​ (UPOE) for power-hungry devices like AV systems, industrial sensors, and next-gen APs.

​​Addressing Key User Concerns​​

​​Q: What’s the Power Budget for Connected Devices?​​

The C9300-48H-A offers ​​3,600W total PoE capacity​​, enabling simultaneous support for hundreds of high-power devices without external injectors.

​​Q: How Does It Compare to the C9300-24U-M?​​

• ​​Port Density​​: Doubles port count (48 vs. 24) for large-scale deployments.
• ​​Uplink Speed​​: 100G QSFP28 vs. 40G QSFP+ in the 24U-M.
• ​​Stacking Bandwidth​​: StackWise-1.6T (1.6 Tbps) vs. StackWise-480 (480 Gbps).

​​Licensing and Advanced Capabilities​​

The ​​“-A” suffix​​ denotes ​​DNA Premier licensing​​, which includes:

• ​​Cross-domain orchestration​​ for unified campus, branch, and data center management.
• ​​Stealthwatch integration​​ for real-time threat detection.
• ​​Lifetime 24/7 TAC support​​ and hardware replacement.
  No additional licenses are needed for full SD-Access or AI-driven operational tools.
