How to install Cisco Catalyst C9115I

• Plan placement for optimal coverage by considering ceiling height, room layout, and anticipated device density. Choose a secure mounting location that minimizes physical obstruction and interference.
• Connect the access point to a PoE-enabled switch using the supplied Ethernet cable. Ensure PoE or PoE+ power is available to support reliable startup and operation.
• Mount the unit on the ceiling or wall, align it to maximize line-of-sight coverage to common usage areas, and secure all mounting hardware according to your facility’s safety standards.
• Power up the device and begin the onboarding process through Cisco DNA Center or your compatible wireless controller. Adopt the AP into the management platform and apply initial security and network policies.
• Configure network settings: set SSIDs, security protocols (such as WPA3 and enterprise-grade encryption), guest access policies, and multi‑SSID segmentation if required. Enable RF optimization features like smart channel selection and transmit power control.
• Perform a site survey or use analytics from the management platform to verify coverage, adjust RF profiles for different zones (open areas, conference rooms, hallways), and monitor performance metrics to ensure a consistent user experience.
