phone 7975 SCCP75.9-4-2SR1-1S
two expansion 7916 module B016-1-0-4-2
I configured the phone using SCCP, once the configuration was finalised I connected the phone - 1 x 7916 expansion modules - and its working fine , but when we connect 2 X 916 expansion , the status that the 2 expansion keep resetting , could it be simply power supply related. The two expansion modules are connected to an external power supply.
Please follow these steps:

Cisco Unified IP Phone Expansion Module 7916
Have you tried connecting only the one is resetting?
Does it work?
Are you plugging the power cube to the right sidecar?
Just in case, follow these steps for connecting both Expansion Modules:
1) Plug one end of the second interface cable into the AUX jack with the “out” icon underneath on the first Expansion Module (the one closest to the phone).
2. Plug the other end of the second interface cable into the AUX jack with the “in” icon underneath on the second Expansion Module (the one next to the first Expansion Module).
If that doesn't work, let's try making a factory reset to phone.
