5. The IP telephone connects to the TFTP or HTTP server and looks for an upgrade script file.
During TFTP or HTTP processing for the 4601 IP Telephone, both Call Appearance Line
indicators flash continuously 500 milliseconds on, 500 milliseconds off while all other LEDs
remain lit. If the appropriate information cannot be discerned or is missing, both of the
4601’s Call Appearance Line indicators flutter 50 milliseconds on, 50 milliseconds off three
times. All other 4601 LEDs remain lit, and a reset occurs.

The read request packet might have to be sent several times. Each time the RRQ message
is sent, all IP telephones except the 4601 display one of the following messages:
For TFTP, # is the number of TFTP requests made by the phone and www.xxx.yyy.zzz
is the IP address of the current TFTP request. For HTTP, n is the number of HTTP requests
made by the phone and uri is the URI for the current HTTP request.

the following message:
where n is the number of KBs received from the TFTP server.

4601 display the following message:
