Hi Sprout,
The power loss of network cables also needs to be considered during the calculation.
For example, the resistance of the CAT5 network cable of the 100M is about 20 ohms, so the loss of the 100M network cable is =(25w/50v)^2*20=5W. Therefore, the number of APs supported by the switch=370/(25+5)=12.
