Should you need to reconnect your Cisco 8851 IP phone — perhaps you have moved to a new office — follow these guidelines. Your phone works in conjunction with your computer and can be plugged into both a network port and your TU-owned computer. If there is no computer, plug the phone into a network data port directly. The diagram below identifies the connections on your Cisco 8851 IP phone; all connections are on the back of the phone, at the bottom.
