how to install Cisco Catalyst CW9166I

• Plan a strategic installation location with clear line‑of‑sight to underserved areas and high‑density hotspots; ensure the site has an available PoE network connection and adequate cooling.
• Mount the CW9166I on a ceiling or wall using the included hardware. Verify there is access to a 2.5 GbE uplink port and a PoE+ power source consistent with IEEE 802.3at/af standards.
• Connect the AP to your network switch or PoE injector, and power it up. Wait for the device to boot and reach the management plane (cloud or on‑premises) as configured.
• Access the initial configuration through the preferred management method: a cloud portal for cloud deployments or the local web UI/Cisco DNA Center for on‑premises setups. Configure SSIDs, security (WPA3), VLANs, and basic RF settings to establish a reliable baseline.
• Activate ongoing management and optimization: apply firmware updates, enable RF optimization features, and enroll the CW9166I into your centralized management platform for policy consistency, monitoring, and analytics across your network.
