When you buy all Cisco IP phones, without the power adaptor, so how to work?

There are 3 options for connections.

1) Buy power transformer (CP-PWR-CUBE-3) directly; suitable for few Qty, will be an economic method.

2) If you have POE switches, will be better. Connect by a RJ-45 cable directly.

POE switch: e.g. WS-C2960-24PC-L (24 Ports), WS-C2960-48PST-L (48 ports) and so on.

3) For long-distance consideration within 100 meters, you also can connect with Power Injector (CP-PWR-INJ).
