So I have a 3650 poe switch from cisco and 2 7960 ip phones that use poe, I have one phone on a short patch lead and this phone powers on fine
Now with the second phone, it has a 50m patch cable and for some odd reason only powers up when on port 10 of the switch, I have tried all the other phone ports that are configured and only port 10 works.
The same config has been applied to all other ports but the phone persists to only power on on port of
What is the problem here?
Thanks in advance
