Removing the Replacing the Cisco Unified IP Phone With Networks that Use a
Dynamic IP Address
If your network uses the Dynamic Host Configuration Protocol (DHCP) to dynamically allocate an IP
address for your Cisco TelePresence system, complete the following steps to replace your Cisco Unified
IP Phone.
Step 1 Unplug the Ethernet cable from the back of the existing Cisco Unified IP Phone.
The Ethernet port is marked as 10/100 SW.
Step 2 Make a note of the MAC Address of the new Cisco Unified IP Phone.
Find the MAC address on a white sticker on the rear of the phone, next to the Ethernet port.
Step 3 Log in to the Unified CM Administrative GUI.
Step 4 Enter the MAC address of the new Cisco Unified IP phone into the Administrative GUI.
The phone settings are stored in Unified CM and the MAC address is required for the phone to register
with Unified CM.
Step 5 Connect the new Cisco Unified IP Phone to the Ethernet cable to the 10/100 SW port (the same port as
was used on the existing phone).
The IP phone starts booting with the Power over Ethernet (PoE) power provided by the TelePresence
codec and attempts to register with Unified CM.
Step 6 Wait for the phone to complete its bootup procedure.
After the IP phone has successfully booted up and registered with the Call Manager, the IP phone ready
screen will display. See Figure 5-12 for an example of this screen.
