Good morning
My name is Paolo and I write from Italy
I'm sorry for my bad english
I have encountered a frequent problem on cisco 3905 phones:
The POE port fails and the phone no longer works
if you connect an external power supply to the phone
the phone works.
The phone no longer receives energy from the data port.
is this a software problem that can be repaired?
Or is it a broken hardware component?
Is the solution unknown or are there documents to repair?
Thanks for your attention Yours sincerely. Paul
 
Hello. What is the switch model? What category are the cables? How many phones are connected to the switch?
