I have two 3550 switches, which are not POE switches.  Are POE switches required for your Cisco studies?  In other words, IS POE specfic knowledge tested?  Please let me know, as I am thinking about replacing one of the switches for a POE but only if required.

 

Thanks,

 

Anthony

    Hi Anthony,

     

    POE switches are not really needed for Cisco studies. U can also use external power adapter for IP phones. POE switches are created to reduce the external power supply given by power adapters. POE switches use CDP protocol to know the power needed by IP phones and deliver the exact power.
