Configuring Startup Network Settings
3. Some or all of the line keys flash green.
Normally, this sequence takes just a few seconds. However, if the phone flash memory is erased or
the phone load is corrupted, the sequence of green flashes will continue while the phone begins a
software update procedure. If the phone performs this procedure, the following buttons light to
indicate progress:
– Headset—Phone is waiting for the network and completing CDP and DHCP configuration. (A
DHCP server must be available in your network.)
– Mute—Phone is downloading images from the TFTP server
– Speaker—Phone is writing images to its flash memory
4. The phone screen displays the Cisco Systems, Inc., logo screen.
5. These messages display as the phone starts:
– Verifying load (if the phone load does not match the load on the TFTP server). If this message
displays, the phone start up again and repeats step 1 through step 4 above.
– Configuring IP
– Updating the Trust List
– Updating Locale
– Configuring Unified CM List
– Registering
6. The main phone screen displays:
– Current date and time
– Primary directory number
– Additional directory numbers and speed dial numbers, if configured
– Softkeys
If the phone successfully passes through these stages, it has started up properly. If the phone does not
start up properly, see Resolving Startup Problems, page 9-1.
Configuring Startup Network Settings
If you are not using DHCP in your network, you must configure these network settings on the
Cisco Unified IP Phone after installing the phone on the network:
• IP address
• IP subnet information (subnet mask for IPv4 and subnet prefix length for IPv6)
• Default gateway IP address
• TFTP server IP address
You may also configure these optional settings as necessary:
• Domain name
• DNS server IP address
