I have CISCO catalyst 2960 switches on the network and not supported POE, When we plug in the NEC DT700 Series IP phones, we get no power.
question 1: If we buy cisco power injectors or hub to power up the IP phones, will that work?
and what's this inector model?
question 2: If we buy the PowerDsine (which "adds" the POE feature to the non-POE switches), will it be compatible with the Catalyst 2960 switches not supported POE? and the NEC IP phones?
