How to install Cisco Catalyst 9120AXE Dual Band Indoor Wireless Access Point

• Plan your deployment: Assess the workspace to determine optimal AP placement for maximum coverage and minimal interference. Create site surveys or heat maps to identify central locations with clear paths to high-density areas.
• Prepare mounting and power: Choose ceiling or wall mounting hardware, and ensure a PoE+ capable switch or injector is available to provide both power and data via Ethernet.
• Mount the AP: Secure the 9120AXE to the selected mounting point using the included hardware. Ensure there is adequate clearance around the unit to allow for airflow and optimal radio performance.
• Connect and power: Run an Ethernet cable from the PoE+ switch or injector to the AP and power on. Verify link status and basic connectivity to the wider network.
• Initial configuration: Access the AP through your network management platform (e.g., Cisco DNA Center or the local web UI) to configure SSIDs, security policies, and basic operating parameters. Enable essential features such as WPA3 security, 802.1X authentication, and VLAN tagging as needed.
• Optimize performance: Enable roaming assistance, set channel plans to minimize interference, configure QoS for critical applications, and apply RF optimization settings like band steering and transmit power controls appropriate for the environment.
• Monitor and adjust: Use the management platform to monitor client connections, health, and throughput. Make iterative adjustments to placement, power, and channel assignments to maintain optimal performance as the network grows.
• Document and maintain: Record deployment details, IP addressing, SSIDs, and security settings for future audits and scaling. Schedule regular firmware updates and security patches to keep the network protected.
