how to install Cisco Catalyst 9120AXI 802.11ax 5.38 Gbit/s Wireless Access Point

• Plan placement: Choose high‑traffic areas with clear sightlines to maximize coverage. Avoid mounting near large metal surfaces or dense objects that can interfere with RF performance. Use heat maps or predictive planning tools to identify optimal locations.
• Prepare the network: Ensure your switch or PoE injector provides adequate power (PoE/PoE+ as required) and establish a management VLAN. Confirm IP addressing, DNS resolution, and access control policies align with your security design.
• Mount and connect: Mount the AP on the ceiling or wall according to your architectural plan. Connect the uplink to the network switch using a trunk or access port as designated by your design. Power on and verify the LED indicators reflect normal operation.
• Adopt and configure: Use Cisco DNA Center or your preferred controller to adopt the AP, push firmware updates, and apply network policies such as SSIDs, security protocols, and guest access rules. Validate RF profiles and ensure proper client steering and load balancing settings.
• Verify performance: Run post‑deployment validation to confirm coverage, latency, and throughput. Check client association rates, jitter, and interference levels. Fine‑tune channel widths and transmit power to optimize performance for your environment.
