PoE switch connecting to AP

To connect a PoE switch to an access point, plug the AP's Ethernet port directly into a PoE-enabled port on the switch, ensuring the switch provides sufficient power and network connectivity.Physical ConnectionUse a PoE-enabled port: Connect an Ethernet cable from the AP's Ethernet jack to a PoE port on the switch. This port will supply both data and power to the AP, eliminating the need for a separate power adapter (Cisco documentation, TP-Link guide, Ubiquiti guide) .Cable type: Use a standard Cat5e or higher Ethernet cable to ensure proper data transmission and power delivery.Optional PoE adapter: If the AP is sold as a single unit without a PoE switch, a PoE injector or adapter can be used to provide power while connecting to a non-PoE switch (Ubiquiti Quick Start Guide) .PoE Standards and Compatibility802.3af (PoE) provides up to 15.4W per port, suitable for most standard APs.802.3at (PoE+) provides up to 30W per port, required for higher-power APs.Ensure the AP's power requirements match the switch's PoE output. Some passive PoE APs require specific pinouts and may not work with standard PoE switches (TP-Link guide) .Network ConfigurationSwitch port mode: Configure the switch port as an access or trunk port depending on your VLAN setup. For multiple VLANs, use trunk mode and allow the necessary VLANs for client and management traffic (Cisco guide) .DHCP: Ensure the VLAN associated with the AP has an active DHCP scope, either on the switch or an external DHCP server, so the AP can obtain an IP address.Controller association: For managed APs, verify that the AP can reach its controller or management system once powered and connected. The AP's LED should indicate a valid IP and readiness to join the network.Additional ConsiderationsSwitches before or after AP: PoE must be delivered directly from a PSE (Power Sourcing Equipment) to the AP. If you need additional ports at the AP location, a non-PoE switch can be connected after the AP's Ethernet port, but it will not pass PoE to other devices (Network Engineering guidance) .Outdoor APs: For outdoor deployments, PoE switches can be combined with fiber backhaul for high-speed connectivity while still powering the AP over Ethernet (Ubiquiti guide) . By following these steps, your AP will receive both power and network connectivity from the PoE switch, ensuring proper operation and integration into your network.
