Core Architecture & Port Configuration

The ​​C9300X-48TX-A​​ is a Catalyst 9300X Series switch optimized for ​​high-speed access-layer deployments​​, featuring ​​48x 10GBase-T ports​​ with ​​802.3at PoE+​​ support. This design caters to environments requiring ​​10G connectivity​​ for devices like ​​Wi-Fi 6/7 APs​​, ​​4K surveillance systems​​, and ​​collaboration endpoints​​ without external power injectors.

Uplink Scalability & Modular Design

Equipped with ​​two modular uplink slots​​, the switch supports Cisco’s ​​Network Interface Modules (NIMs)​​ for 40G QSFP+ or 100G QSFP28 uplinks. The ​​-A​​ suffix denotes ​​reverse airflow​​, making it ideal for hot-aisle/cold-aisle containment in data centers. ​​StackWise Virtual​​ enables seamless stacking over 10/40/100G links, simplifying multi-switch management.

Security & IoT Integration

Integrated with ​​Cisco DNA Center​​, the switch enforces ​​zero-trust segmentation​​ for IoT devices and endpoints. ​​MACsec-256 encryption​​ is hardware-accelerated on all ports, ensuring compliance with stringent data privacy regulations in sectors like finance or education.

Power Efficiency & Thermal Resilience

​​EnergyWise technology​​ dynamically adjusts power delivery to connected devices, reducing energy waste by up to ​​30%​​ compared to fixed-power models. The switch operates reliably at ​​ambient temperatures up to 45°C​​, suited for industrial or crowded edge environments.

Deployment Scenarios & Use Cases

• ​​High-density workspaces​​: Deliver 10G connectivity to desktop workstations and video conferencing systems.
• ​​AI-driven IoT hubs​​: Host Cisco IOx applications for localized data processing from sensors or cameras.
• ​​Converged networks​​: Power PoE+ devices like access points and digital signage while maintaining wire-speed throughput.

Licensing & Operational Considerations

The switch ships with ​​Cisco DNA Essentials​​, but ​​DNA Advantage​​ unlocks advanced features like SD-Access and SaaS application monitoring. For traditional networks, ​​Network Essentials​​ or ​​IP Base​​ licenses support static routing and basic QoS policies.

Procurement & Compatibility

Final Insight: Balancing Speed & Practicality

Having deployed Catalyst 9300X switches in campus and edge environments, the ​​C9300X-48TX-A​​ stands out for its ​​10GBase-T density​​ and ​​PoE+ flexibility​​. Its modular uplinks allow cost-effective scaling to 100G cores, while EnergyWise slashes operational costs in always-on deployments. For organizations prioritizing future-ready wired access without overprovisioning, this model eliminates the trade-off between performance and simplicity.
