Hello, there is smart PoE (which can be found in Configure> Network Policy> Advanced Settings> Management options), which applies to the AP models 230, 320, and 340. If you have this enabled these AP models will detect if there are power injectors connected to one or both Eth ports and how many watts are available for each channel. The AP will manage it's internal power usage based on the currently available power that it detects. You can find more details about this on this page- https://docs.aerohive.com/330000/docs/help/english/ng/Content/gui/configuration/configuring-management-options.htm (Expand Miscellaneous Settings and look for "Enable Smart PoE").
Otherwise, you can set the power manually on any AP with the following command:
system power-mode <802.3af/802.3at/auto>.
If you set the power on the CLI, keep in mind that CLI configuration commands get wiped out after each reboot, so you'd want to make a supplemental CLI object for this command so it is applied to your APs after each reboot.
