​​Introduction to the Cisco Catalyst C9300-48T-1A​​

The ​​Cisco Catalyst C9300-48T-1A​​ is a high-port-density Layer 3 switch designed for enterprise networks requiring scalable copper connectivity without Power over Ethernet (PoE). Part of the Catalyst 9300 series, it targets organizations prioritizing ​​cost-effective scalability​​, advanced security, and seamless integration with Cisco’s software-defined networking (SDN) ecosystem.

​​Core Technical Specifications​​

• ​​48x1G Copper Ports​​: Non-PoE RJ45 interfaces for connecting servers, workstations, and legacy devices.
• ​​4x10G SFP+ Uplinks​​: Supports high-speed stacking via ​​Cisco StackWise-480​​ (480 Gbps bandwidth) or backbone connectivity.
• ​​Cisco DNA Advantage Licensing​​: Includes ​​SD-Access segmentation​​, ​​AI-driven network analytics​​, and ​​automated threat response​​.
• ​​Energy Efficiency​​: Consumes 25% less power than older Catalyst 3850/4500E models.

​​Addressing Key User Concerns​​

​​Q: Is the C9300-48T-1A Suitable for PoE Deployments?​​

No. The ​​“48T”​​ designation confirms ​​non-PoE copper ports​​. For PoE+ or UPOE, consider the ​​C9300-48P-A=​​ or ​​C9300-48U-A​​ models.

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

• ​​Port Density​​: Double the copper ports (48 vs. 24) for large office or campus deployments.
• ​​Licensing Tier​​: DNA Advantage (included with “1A”) offers ​​SD-Access​​ and ​​AIOps tools​​, unlike DNA Essentials in the “-E” model.
• ​​Uplink Flexibility​​: Both support 10G SFP+, but the 48T-1A is optimized for high-density edge-to-core traffic.

​​Licensing and Advanced Features​​

The ​​“-1A” suffix​​ signifies ​​DNA Advantage licensing​​, which provides:

• ​​Software-Defined Access (SD-Access)​​ for micro-segmentation and policy enforcement.
• ​​Cisco Stealthwatch integration​​ for network-wide threat visibility.
• ​​Lifetime hardware warranty​​ with 24/7 Cisco TAC support.
  Upgrading to ​​DNA Premier​​ adds multi-domain orchestration and encrypted traffic analytics.

​​Final Evaluation​​

The C9300-48T-1A strikes a pragmatic balance for enterprises needing high-density copper connectivity without PoE overhead. Its DNA Advantage tools simplify network segmentation and threat management, making it ideal for environments like financial campuses or government offices where data security and port density outweigh PoE requirements. While not the cheapest Catalyst 9300 variant, its Total Cost of Ownership (TCO) is justified for IT teams prioritizing scalable, software-driven network modernization. For businesses planning gradual SDN adoption, this switch is a strategic stepping stone.
