In addition, problems with security may prevent the phone from starting up properly. See the “General Troubleshooting Tips” section on page 9-8for more information.

Identifying Error Messages

As the phone cycles through the startup process, you can access status messages that might provide you with information about the cause of a problem. See the “Status Messages Screen” section on page 7-2for instructions about accessing status messages and for a list of potential errors, their explanations, and their solutions.

Checking Network Connectivity

If the network is down between the phone and the TFTP server or Cisco Unified Communications Manager, the phone cannot start up properly. Ensure that the network is currently running.

Verifying TFTP Server Settings

You can determine the IP address of the TFTP server used by the phone by pressing the Applications button, then selecting Admin Settings > Network Configuration > IPv4 > TFTP Server 1.

If you have assigned a static IP address to the phone, you must manually enter a setting for the TFTP Server 1 option. See the “Network Setup Menu” section on page 4-4.

If you are using DHCP, the phone obtains the address for the TFTP server from the DHCP server. Check the IP address configured in Option 150.

You can also enable the phone to use an alternate TFTP server. Such a setting is particularly useful if the phone was recently moved from one location to another. See the “Network Setup Menu” section on page 4-4for instructions.

Verifying IP Addressing and Routing

You should verify the IP addressing and routing settings on the phone. If you are using DHCP, the DHCP server should provide these values. If you have assigned a static IP address to the phone, you must enter these values manually.

On the Cisco Unified IP Phone, press the Applications button, then select Administrator Settings > Network Configuration > IPv4, and look at the following options:

•Boot/DHCP Server—If you have assigned a static IP address to the phone, you do not need to enter a value for the DHCP Server option. However, if you are using a DHCP server, this option must have a value. If it does not, check your IP routing and VLAN configuration. Refer to the Troubleshooting Switch Port and Interface Problems document, available at this URL: http://www.cisco.com/en/US/customer/products/hw/switches/ps700/products_tech_note09186a00 8015bfd6.shtml

•IP Address, Subnet Mask, Default Router—If you have assigned a static IP address to the phone, you must manually enter settings for these options. See the “Network Setup Menu” section on page 4-4for instructions.
