386 Expansion Module for IP Phones 1100 Series

Set Info

The Set Info menu displays the firmware version for the IP Phone and

any attached Expansion Modules. The attached Expansion Modules are

identified as KEM1, KEM2, and KEM3. KEM1 is the closest to the IP

Phone. The Expansion Module identifies the firmware as a three character

string; the TPS displays the firmware in an n.nn format.

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, then distributed

to 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 “TFTP

Server” (page 649).
