Cisco C9300-48UN-A | Catalyst 9300 48-Port Multigigabit UPOE Switch, 645W, Network Advantage

Q: What network modules are compatible with the C9300-48UN-A?
A: The C9300-48UN-A supports Catalyst 9300 and 3850 network modules including C9300-NM-4G (4x1G), C9300-NM-8X (8x10G), C9300-NM-2Q (2x40G), C9300-NM-4M (4xmGig), and C9300-NM-2T (2x25G). The modular uplink slot is sold separately and provides flexible upgrade paths for 1G, 10G, 25G, or 40G connectivity.

Q: Can I stack the C9300-48UN-A with other Catalyst models?
A: Yes, the C9300-48UN-A supports mixed stacking with other Catalyst 9300 and 9300X models using StackWise-480 technology at 480 Gbps speeds. You can stack up to 8 switches for unified management. However, it cannot be stacked with fixed-uplink models like C9300L or older Catalyst 3850/3650 series.

Q: What devices benefit most from the multigigabit and UPOE features?
A: The 5 Gbps multigigabit ports are ideal for Wi-Fi 6/6E access points, which require higher bandwidth than traditional 1G connections. The 60W UPOE capability powers high-demand devices such as PTZ cameras, digital building sensors, LED lighting systems, UHD video endpoints, and next-generation wireless access points without requiring separate power sources.

Q: What does the Network Advantage license include?
A: Network Advantage licensing unlocks full Layer 3 routing, advanced security features including MACsec-256 encryption and Encrypted Traffic Analytics, SD-Access fabric integration with micro-segmentation, LISP/VXLAN support, and full API programmability for automation and orchestration via Cisco DNA Center.

Q: How do I increase the PoE power budget beyond 645W?
A: The C9300-48UN-A has dual PSU slots. Adding a secondary AC power supply increases the available PoE budget: adding PWR-C1-350WAC provides 995W total, PWR-C1-715WAC provides 1360W, or a second PWR-C1-1100WAC provides up to 1745W of total PoE power for the most demanding high-density deployments.
