If you want to use Power over Ethernet but your network does not have this capability, you will need to use a Power over Ethernet (PoE) Injector as an adaptor between the phone (or wireless base unit) and the router.
To connect a PoE Injector
- Plug the power cable from the power supply to a wall outlet.
- Plug an Ethernet cable from the Data & Power Out port to the phone or base unit Ethernet port.
- Plug an Ethernet cable from the the Data In port to the router or switch.
For example, if you may connect a Spectralink DECT base unit to a PoE Injector. If everything is connected correctly, the Spectralink DECT base unit will have an LED on the top that will turn green, and the Ethernet port on the back will have a blinking green light (labeled ACT) to indicate network activity.
