Hi Kris,
a. What is the CUCM version u are using ?
b. what is the 9971 firmware?
c. Does the phone work fine when single KEM is connected ?
d. How the 9971 phone is getting power? IF it is working on 802.3AF , then u need to connect power CUBES to both KEMs.

Firmware is 9.3.4.24. CUCM version is 8.6.2. I use power cube. Resets happens when BLF is configured on Phone, Phone + 1CKEM or Phone + 2CKEM.

Hi
9971 geting power for power cube 4 (48W), when i do not configure BLF - phone works fine with CKEM and SD buttons. I can only configure max 4 BLF (on phone or CKEM), when i configure more then 4 BLF on phone or CKEM - phone starts resets and register to backup CUCM, then to SRST, then to Primmary CUCM, then to Backup ... Subscribe CCS is ok, Phone is in Default Presence Group.
Thanks for any help

Hi Marcin,
I could not find the cause /bug behind such behaviour.
If anybody has come across the issue,please advise.

I don't think you could power both modules by regular PoE. Are you using external power adapters for the module?
