Cisco Systems 7940G Manual De Usuario

In addition, problems with security may prevent the phone from starting up properly. See the 

 for more information.

As the Cisco Unified IP Phones 7960G/7940G cycle through the startup process, you can access status 
messages that might provide you with information about the cause of a problem. See the 

 for instructions about accessing status messages and for a list of 

potential errors, their explanations, and their solutions.

A Cisco Unified IP Phone can register with a Cisco Unified Communications Manager server only if the 
phone has been added to the server or if auto-registration is enabled. Review the information and 
procedures in the 

 to ensure that the phone has been added to the Cisco Unified Communications Manager 

database.

To verify that the phone is in the Cisco Unified Communications Manager database, choose Device > 
Phone > Find from Cisco Unified Communications Manager Administration to search for the phone 
based on its MAC Address. For information about determining a MAC address, see the 

.

If the phone is already in the Cisco Unified Communications Manager database, its configuration file 
may be damaged. See the 

 for assistance.

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.

The Cisco Unified IP Phone uses the TFTP Server 1 setting to identify the primary TFTP server used by 
the phone. You can determine this setting by pressing the Settings button on the phone, choosing 
Network Configuration, and scrolling to the TFTP Server 1 option.

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 

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 a from one location to another. See the 

 for instructions.
