Model 480i SIP Admin Guide  20 

The 480i phone uses a TFTP server 
to download conÞguration Þles and 
Þrmware. The TFTP server should 
be ready and be able to accept 
connections anonymously (without 
a requirement for a user name and 
password). See Appendix B for 
information on setting up a 
TFTP server. 
You can download the Þrmware 
stored on the TFTP server in one of 
two ways, by either resetting the 
phone through the options list of 
the 480i or by activating a Þrmware 
download through the web client. 
Resetting the phone will force the 
phone to check for both Þrmware 
and conÞguration Þles stored on the 
TFTP server.
Warning: Do not reset or turn off 
the phone until the download is 
complete.
