Connecting an AC Adaptor to an IP Telephone
IP-PTs and some SIP phones comply with the IEEE 802.3af Power-over-Ethernet (PoE) standard. If PoE is
available on your network, these IP telephones can receive the necessary power supply from the network
through the network cable. In this case, no AC adaptor is needed for the IP telephones.
However, if PoE is not available, you will need to connect an AC adaptor to the IP telephone.
Note
Use only the specified type of AC adaptor for each IP telephone. For details, refer to the documentation of
your IP telephone.
