Firmware

553-3001-368 Standard 26.00
Expansion Module for IP Phone 1100 series
The Expansion Module uses a TFTP or UFTP Server to upgrade the
firmware. The firmware is downloaded to the IP Phone, which is then
distributed to the each attached Expansion Module, one at a time. After the
Expansion Module confirms to the IP Phone that the firmware file is
downloaded and saved successfully, the IP Phone starts the download to the
next attached Expansion Module.
If any error causes the firmware download to fail, or if the saved firmware file
is corrupted, the Expansion Module reverts to the factory installed firmware.
The factory installed firmware file is always available to facilitate firmware
download in case the downloaded firmware is unusable.
For more information about TFTP Server firmware upgrade, see
Appendix Appendix H:: "TFTP Server" on
