Additionally, the Cisco IP Phone 7900 Family Administration Guide includes regulatory compliance information about your phone, which your system administrator can review.


Warning This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. (To see translations of the warnings that appear in this publication, refer to the appendix "Translated Safety Warnings.")

Installing the Phone and Connecting to the Network

Read the information in the "Safety Notices" section before installing your phone. Refer to Figure 2-1 for an overview about how to connect the Cisco IP Phone 7940/7960 to your personal computer (PC), network, power, and headset. All phone connection ports are located at the rear of the phone base unit.

Use the following procedure to install the phone on a network that has already been prepared to host the phone.


Step 1 Connect an Ethernet cable to the network port (middle port) on the phone.

Use the Ethernet cable supplied in the box with your IP phone. If you need a longer Ethernet cable, contact your system administrator.

Step 2 Connect the handset (bottom port) and the headset (top port) to their respective port connector.

See the "Using the Headset" section for a list of supported headsets.


Note If you are not connecting to a computer or using an AC power adapter, proceed to Step 5.
