I have an issue with a Cisco Expansion modules 7916 attached to a 7965 phone. Phone died and I have replaced it with a refurbished one from Cisco. After configuring refurbished phone through CLI I have noticed that both 7916 expansion modules just show Cisco screen and buttons underneath display are led amber. I have configured them through CLI as well but I can't get them to work. Phone works just fine but expansion modules don't. See picture attached. Any suggestions?
I am having this exact same issue. I have 5 other 7916s on the network all working fine.
If i take one of the sidecars of my two from the phone that is not working and put it with another phone that has a working car, it works no problem. I have tried two replacement phones now at the position with the failure. No luck.
