INSTALLING THE TS-550i
CONNECTING THE IP PHONE
The figure below shows the cable connections for your IP phone. The LAN and desktop PC connections
employ standard Category 5 cables terminated with RJ-45 connectors. The TS-550i supports PoE (Power
over Ethernet) in accordance with the IEEE-802.1af Class 2 standard. When connected to a PoE compliant
LAN port, the IP Phone derives power from the port. If the LAN port does not support PoE, use the AC/DC
adaptor (sold seperately). The handset connects to the base with the coiled handset cord.
