Core Features of the C9300-48U-A=
The Cisco Catalyst 9300-48U-A= is a high-density PoE+ switch optimized for modern enterprise networks. Its critical specifications include:
- 48x 1G RJ45 ports with PoE+ support, delivering up to 30W per port for devices like IP phones, surveillance cameras, and wireless access points.
- 740W total PoE+ budget to power energy-intensive endpoints without additional power injectors.
- StackWise-320 technology, enabling flexible stacking with up to 8 switches and 320 Gbps stacking bandwidth.
- Cisco DNA-ready for seamless integration with SD-Access and automated network management.
Ideal Deployment Scenarios
The C9300-48U-A= is best suited for environments requiring high port density and PoE scalability:
- Corporate offices: Supports large-scale VoIP deployments with uninterrupted PoE+ for IP phones and video conferencing systems.
- Retail spaces: Powers PoE-driven IoT devices, such as digital signage, POS systems, and inventory scanners.
- Educational institutions: Manages dense Wi-Fi 6 AP deployments and classroom AV equipment.
Addressing Common Buyer Questions
Q: Does the C9300-48U-A= support Layer 3 routing?
A: Yes. It provides dynamic routing protocols (OSPF, EIGRP, BGP) and advanced QoS features, making it suitable for aggregation layer deployments.
Q: How does it ensure network security?
A: The switch integrates Cisco TrustSec for policy enforcement, MACsec encryption for data confidentiality, and Cisco ISE compatibility for endpoint visibility and access control.

Why This Switch Stands Out in Real-World Deployments
Having configured the C9300-48U-A= in multi-campus networks, its PoE+ redundancy (via dual power supplies) and modular IOS-XE updates are game-changers. While newer Catalyst 9400 switches offer higher scalability, the 48U-A= remains unmatched for mid-sized deployments requiring dense PoE without compromising Layer 3 functionality. For IT teams managing hybrid work environments, its ability to power and prioritize traffic for latency-sensitive applications (e.g., Microsoft Teams, Zoom) makes it a future-proof investment.
