Ensure you are using a POE switch or injector that has adequate power for the access point you are using, you can contact us or look up the datasheet for this information.
-
Ensure the port on the switch is a POE port, Ubiquiti switches indicate this with a⚡symbol.
-
Attempt to use a different cable
-
All Ubiquiti Unifi devices will attempt to obtain an IP address from a DHCP server on the network, nearly every router has this enabled by default so you will need to make sure that the device can reach the router and is not isolated from it.
-
Keep an eye on the light indicator or mini LCD on your unifi device, the light will flash white if initializing so you will need to wait until it's solid white before it's ready for adoption. The Mini LCD should show an IP address in your networks IP range.
-
Ensure there's activity on the ethernet port by looking at the light on the port, most routers have this and the light should be flashing quite frequently. If there's no light or minimal activity, try a different cable or port.
