How to install Cisco Catalyst C9120AXI

• Plan placement to maximize coverage: mount near the center of high‑density zones and avoid obstructions that could degrade signal integrity. For best results, consider ceiling mounting in conference rooms and open workspaces to minimize dead zones.
• Prepare power and cabling: use PoE+ (IEEE 802.3at) switches or a compatible injector. Use CAT5e/6+ cabling rated for your network speed to ensure reliable connectivity and future‑proofing.
• Connect and power up: attach the AP to the network, apply the necessary power, and verify physical installation integrity. Ensure mounting hardware aligns with enclosure specifications for secure operation.
• Configure network access and security: adopt the AP into your Cisco management environment (such as DNA Center) and apply consistent SSIDs, WPA3 security policies, and guest access controls as required by your policy framework.
• Optimize radio settings and ongoing monitoring: enable OFDMA and MU‑MIMO where appropriate, set channel plans and transmit power to reduce interference, and leverage analytics from your management platform for ongoing performance tuning.
