Depending on switch vendor and quality, they can actually increase the voltage output - the spec iirc allows for up to 57V at PSE which an intelligent switch can modulate to overcome limited voltage drop - cheaper switches (desktop etc) just supply all ports 54V (or less, but it should be 54 at source) from the same rail without any modulation |
