Connecting the LAN ethernet cable
Note: Your IP Deskphone supports both AC power and PoE options,
including IEEE 802.3 standard power. To use local AC power, you can
order the optional AC adapter separately. To use PoE, where power is
delivered over the CAT5 cable, the LAN must support PoE, and you
do not need an AC adapter.
To enable full functionality of your IP Deskphone, connect your IP
Deskphone to your LAN using a CAT5e Ethernet cable. If your network is
equipped with PoE, you can power your IP Deskphone through the LAN
port.

1. Connect one end of the supplied Ethernet cable to the back of your IP
Deskphone by using the RJ-45 connector marked with the % symbol.
