Firmware - Nortel 1110 Fundamentals

442 Expansion Module for IP Phone 1100 Series
Use the Up/Down navigation keys to scroll the list to display the firmware
for each attached Expansion Module. The firmware version is displayed
even if the Expansion Module is not configured in LD 11. In this case, the
Expansion Module is identified in the display area by an asterisk (*) after the
Expansion Module number (for example, KEM1*).
If an Expansion Module is configured but does not respond, the firmware
version displays as <unknown>.

Firmware

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.
