Strange problem here.
2x VVX600 phones with Polycom VVX color Expansion module. Software UC 22.214.171.1245, Bootrom 126.96.36.1990. The problem is that the module don't bootup, it stucks with the Polycom logo en don't switch to the blank screen. Also after a factory reset of the phone the expansion module won't startup.
Tried the expansion module on another phone on another location, everything is working fine.
What could be the problem??
Power of the POE switch to low??
