Recently I upgraded several access swicthes (2960, 3650's) which have POE and Cisco 7962 phones connected. After the upgarde and subsequent reboot, the IP phones failed to power up and are effectively dead.
All that happen on the phone now is that when the POE cable is connected, the phones mute button LED light flashes before the spekaer LED lights up and remains lite up.
Approx 5 phones across multiple switches have died this way.
Can anyone tell me if this is a behaviour they have experience and how they may have recovered from it.
