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

Installing the C9115I is straightforward for IT teams familiar with Cisco wireless deployments. Begin by selecting a location with optimal coverage and network access, preferably near central network resources to minimize latency. Mount the access point on a ceiling or wall using the included mounting brackets and ensure there is adequate clearance for cooling. Connect the device to a PoE-enabled network switch with a standard Ethernet cable, ensuring the switch can provide sufficient power for the unit.

• Power up and verify physical installation. Confirm that the device powers on and that the status indicators reflect normal operation.
• Adopt the AP into your Cisco wireless management domain. Use Cisco DNA Center or the corresponding Wireless LAN Controller to claim the new AP and assign it to an SSID policy, security profile, and radio settings appropriate for the location.
• Configure basic radio settings. Optimize channel selection and transmit power to balance coverage and interference in the environment.
• Set up security and onboarding. Apply strong WPA3 encryption where supported, enable client isolation where appropriate, and ensure firmware is up to date.
• Test connectivity and performance. Connect a few pilot devices to validate roaming, throughput, and reliability before full-scale deployment.
