We bought Cisco 3560-CX-PC-S and ten 3802i AP. The plan is to install nine APs and one to have as a backup. Until a couple of hours I didn't know that our switch is maximum 240 W so basically that means that we can connect only 8 APs on full power. Also, I have found somewhere that AP will also work with 25.8 W so I have made power inline static max 25800 on each port and with this, I can connect 9 APs.
My question is, could I experience some problems because making lower power? I have read that USB will not work but I don't need it.
according to this thread
The minimum power requirement for the 3802 APs is 25watts, you can plug additional accessories into the 3802 like the Halo antennas that will require additional power. if you are going to use the standard AP with out any additional add-ons the 25 watts will work fine
