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 Menu” section on page 7-3 for 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 CallManager, 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 Menu button on the phone and then selecting Settings
> Network Configuration > 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 Configuration Menu”
section on page 4-7.
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 Configuration Menu” section on page 4-7 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.
