You need to use an AC power supply on the base IP Phone 1140E for the backlight on the Expansion Module to work.

is it a bcm 50?bcm 50 must be version 3.0 release for module to work.

1. Reset the phone by disconnecting and re-connecting power.
2. When the Nortel logo appears, press each of the four soft keys in sequence.
3. If no other configuration changes are required, press OK repeatedly until the “PC
Port? 1-ON 0-0FF” option appears.
4. Press 1 to enable the PC Port or 0 to disable the PC Port.
5. Select OK to confirm the change.
6. Restart the IP Phone.
When the IP Phone is restarted, the firmware sets the PC Port status accordingly

here you are...
This could be the problem with your signaling server , have you checked it ??
I think it is losing connectivity of T-Lan Network.

Is it the only IP phone? Howstable is the network?
