Connecting the IP Phone to the LAN
Follow this procedure to connect the terminal to the Local Area Network (LAN) and to a
power source.
Prerequisites
IP Phones can be powered by an AC adapter or over a LAN. Contact your installation
technician to identify the correct power option.
Warning: Risk of equipment damage
Do not plug the IP Phone 1120 into a regular telephone jack. This
causes severe damage to the terminal. Consult your system
administrator to ensure that you plug your telephone into a
10/100BaseT Ethernet jack.
Connecting the IP Phone to the LAN
1. Connect one end of the CAT-5 line cable to the LAN Ethernet port, identified with a
LAN icon, located on the back of the terminal.
2. Connect the other end of the CAT-5 line cable to the IP network jack. For a terminal
sharing LAN access with a PC, connect a second CAT-5 line cable to the PC Ethernet
port located on the back of the terminal, identified by the PC icon. Connect the other end
of the cable to the Ethernet port on the computer.
3. For a secure power connection, thread the cord around the strain relief, retaining hook,
and channel on the back of the terminal.
4. Secure the terminal footstand to the terminal base.
