Dear support,
Can Cisco 500 series switches deliver 24V on the access port for POE operation?

Hi, the SX300/500 supports 15.4 watt.
So if you have 24 V, with 2 amp, that is 48 watt if it is DC.
AC three phase with 24 V, 1 amp and power factor of 1 is 41.5 watt.
AC one phase with 24 V, 1 amp and power factor of 1 is 24 watt.
So I would say no it is not supported.

I belive the 802..2F and 802.2at poe standard is strictly 48v. I haven't found anything to the contrary. There are inline convertes 48v-24v or something like this that can be used with a non poe switch: http://www.digital-loggers.com/poe24.html but that means all conected device would be off the same access port / vlan.
