I have a fleet of the 7960G IP phones and recently bought a couple 7970G phones for use with the managers and am now curious, since we don't have PoE here can I use the PWR-CUBE that I have been using with the 7960s? Or will I need some kind of new power cube for use with that phone. Just thought of that and am afraid to try it with the ones used with the 7960s until I know for sure.
Model of the pwr-cube we have is: 34-1977-03
yes you can use any power cube. Cisco made improvements in further models, but are quite minor things and any will work.
Hope this helps, please rate post if it does!
