Firmware Upgrade
The 480i CT phone uses a TFTP server
to download configuration files and
firmware. The TFTP server should be
ready and be able to accept connec-
tions anonymously (without a require-
ment for a user name and password).
See Appendix B for information on
setting up a TFTP server.
You can download the firmware
stored on the TFTP server in one of
two ways, by either resetting the
phone through the options list of the
480i CT or by activating a firmware
download through the web client.
Resetting the phone will force the
phone to check for both firmware and
configuration files stored on the TFTP
server.
Warning: Do not reset or turn off the
phone until the download is com-
plete.
