Upgrading Wireless Phones
After software updates are obtained, they must be transferred to the appropriate location in the LAN to
update the code used by the wireless phones.
The wireless phones allow over-the-air transfer of software updates from the designated TFTP server to
the wireless phones. The downloading function in the wireless phone checks its software version every
time the wireless phone is turned on. If there is any discrepancy the wireless phone immediately begins
to download the update.
Normal Download Messages
When the wireless phone is powered on, it displays a series of messages indicating that it is searching
for new software, checking the versions and if necessary downloading. The list below shows the normal
message progression:
1.
Checking Code
The wireless phone is contacting the TFTP server to determine if it has a newer version of
software that should be downloaded.
2.
Erasing Memory
The wireless phone has determined that a download should occur and is erasing the current
software from memory. This message also displays a progress bar. When the progress bar fills
the display line the erase operation is complete.
3.
Updating Code
The wireless phone is downloading new software into memory. The number icons at the bottom
of the display indicate which file number is currently being downloaded. This message also
displays a progress bar. When the progress bar fills the display line the update operation is
complete on that file.
When the update is complete, the wireless phone displays the extension number and is ready to use.
