Does a cloudUC Poly (Polycom) phone require a separate power source?

Your cloudUC Poly (Polycom) phone can be powered in two ways. One way would be utilizing an optional power supply which would plug into a standard 110 AC outlet at the workstation. The other way would be using Power over Ethernet (PoE). PoE provides power to the phone via the Ethernet cable that also provides network connectivity to the phone. Typically PoE is delivered through the use of a PoE equipped Ethernet switch that is installed in the network/telecom/server room. Additionally, PoE power injectors are available if a PoE switch is not available. NCTC strongly recommends PoE switching for most deployments as a centralized power source with a recommended battery backup/UPS can continue to power your cloudUC phones in the event of a short term power outage.
