Chapter 9 Troubleshooting and Maintenance Resolving Startup Problems If you are using DHCP, the phone obtains the address for the TFTP server from the DHCP server. Check the IP address that is configured in Option 150. Refer to Configuring Windows 2000 DHCP Server for Cisco Unified CallManager that is available at this URL: http://www.cisco.com/warp/customer/788/AVVID/win2000_dhcp.html You can also enable the phone to use an alternate TFTP server. You will find such a setting is particularly useful if the phone was recently moved from one location to another. See the "Network Configuration Menu" section on page 4-6 for 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, choose Settings > Network Configuration, and look at the following options: • 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, you must ensure that this option has a value. If it does not, check your IP routing and VLAN configuration. Refer to Troubleshooting Switch Port Problems that is available at this URL: http://www.cisco.com/warp/customer/473/53.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 Configuration Menu" section on page 4-6 for instructions. OL-8726-02 Cisco Unified IP Video Phone 7985G Administration Guide 9-5

the DHCP server. Check the IP address that is configured in Option 150. Refer to

You can also enable the phone to use an alternate TFTP server. You will find such
a setting is particularly useful if the phone was recently moved from one location
to another. See the
“Network Configuration Menu” section on page 4-6

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, choose

not need to enter a value for the DHCP Server option. However, if you are
using a DHCP server, you must ensure that this option has a value. If it does
not, check your IP routing and VLAN configuration. Refer to
