HI
Dear administrators I'm facing an issue with a Cisco 3650 switch with 48 ports.
On this switch 17 ports are not working so all ip phones plugged are not on " no electricity or no power" ,
how could I handle ?
thnks for help

Post up the model number and we can find out how much power u got. Also was it all working before?Currently Reading

17 out of 48 not working is funky, doesn't make me think the PSU is going..post results of the above.Modularity and Design Simplicity:
Think of the 2:00 a.m. test—if you were awakened in the
middle of the night because of a network problem and had to figure out the
traffic flows in your network while you were half asleep, could you do it? -

Do a show power inline to see if your using all the POE allocated power if you aren't then do a TDR test on the interfaces that are giving you trouble.... I work in an environment with thousands of access switches - the 3560's have POE issues bad; we stopped using them and went to the 2960S models (plus 2960S support 48 POE III ports).
Sometimes it can be something funky layer 1 and the TDR test will resolve it...
Can you do a show power inline and post it for us? -

Yeah, the 3560s are not intended to be loaded up with the newer color phones. The V02s are much better, but still not enough juice for the newer stuff.CCNP:Collaboration, CCNP:R&S, CCNA:S, CCNA:V, CCNA, CCENT -

Well power quantity is the issue 3% of the time 50% of the time its the wiring; 42% of the time its the actual 3560, 5% of the time its user error lol. -
