I just enable it on ports I know will have PoE devices. when it's enabled on all ports at the same time with one power supply the default allocation is something like 12 watts per port instead of the full. You can override that for certain ports, but easier to just enable the ports you need.Got it working, thanks! Is it bad to enable PoE on all ports?
if you do enable all ports, turn off legacy PoE detection, as I've seen some devices trigger this and the switch will try to send them power (legacy PoE was identified only by a certain resistance/response on one of the pairs, and I've seen switches that accidentally have this same resistance and trigger a detection). turning it off is just "no legacy-inline-power" at the global config level. make sure to "write memory" to save any cli changes
