Step 2 Set up the network to support one of the following:
• DHCP support
• Manual assignment of IP address, gateway, and subnet mask
Install the Cisco IP Phone
After the phone connects to the network, the phone startup process begins, and the phone registers with the
third party server. To finish installing the phone, configure the network settings on the phone depending on
whether you enable or disable DHCP service.
If you used autoregistration, you need to update the specific configuration information for the phone such as
associating the phone with a user, changing the button table, or directory number.
Before using external devices, read External Devices, on page 20 . Note
If you only have one LAN cable at your desk, you can plug your phone into the LAN with the SW port and
then connect your computer into the PC port.
You can also daisy chain two phones together. Connect the PC port of the first phone to the SW port of the
second phone.
Do not connect the SW and PC ports into the LAN.
