5.1. Connecting IP system phones
Connect the IP system phone LAN ports to the network as shown. The PC port on the IP
telephone may be used to connect a PC, thus allowing a single cable from the desk to carry the
PC traffic and the telephone traffic.
Note: Do not connect any IP system phone to the LAN until the system has access to
Internet;
otherwise the WAN address of the system (relayed by router UPnP) will not be
captured by the IP system phone at power-up.
Note: Do not power up the IP system phones until the system’s IP address is in the
correct range for the LAN, as described previously;
otherwise the IP system phones may be
assigned IP addresses that are not within the same range as the system and auto discovery
cannot work properly.
Connect the LAN port of the Operafone IP system phone (Executive or Professional) to the LAN
using the Ethernet cable supplied with the phone.
