Selected Answer: A
A. Add a PoE injector. If the VoIP phone is not turning on despite a good cable connection, it's possible that the phone requires Power over Ethernet (PoE) to operate, and the switch it's connected to may not be providing PoE. Adding a PoE injector between the switch and the phone can provide the necessary power for the phone to function properly.

It is NOT turning on is the clue. Switch is probably not giving POE (it could been port configuration to give POE, but looks like an injector is another way assuming the switch cannot give the power

Selected Answer: A
A. Add a PoE injector is needed for this phone to work. VoIP phones require power to operate, and they can either be powered through an AC adapter or through Power over Ethernet (PoE). If the switch is not providing PoE, a PoE injector can be used to inject power into the Ethernet cable, allowing the phone to turn on.
