how to install Cisco Catalyst C9115I 802.11ax 5.38 Gbit/s Wireless Access Point

• Plan your coverage and density strategy: Assess the space, user distribution, and IoT device patterns to determine optimal placement, ensuring strong line-of-sight coverage and minimizing interference from neighboring networks.
• Prepare mounting and enclosure: Choose the correct mounting option (ceiling or wall) and install any required brackets or enclosures. Ensure there is adequate ventilation and access to a stable network connection for reliable operation.
• Connect power and network: Use the appropriate power source (PoE or other supported methods) and run Ethernet to the switch or controller. Confirm that the network link is stable and that VLAN tagging or QoS requirements align with your design.
• Adopt and configure via Cisco management: Use the Cisco Wireless LAN Controller (WLC), Cisco DNA Center, or a compatible management platform to adopt the AP. Create SSIDs, define security policies (WPA3 where applicable), configure guest access, and set QoS and roaming preferences.
• Validate coverage and monitor performance: After deployment, perform a site survey to verify signal strength and roaming behavior. Monitor client distribution, interference, and throughput through your management tool, and tune channel selection and power levels as needed.
