What do you mean it is another product? isn't the wiki referring to all mikrotik poe products?
If you read "Models with dependant voltage output" / "Models with selectable voltage output" / "Model-specific LED behaviour"
Doesn't it make you think there are DIFFERENT models?
And if you read "Green colour triangle" / "Red colour triangle", etc.
Where do you see the triangles in that model?
The Hex S does use more power than the Hap ac Lite (12-57 V compared to 10-28 V of hap ac lite)
These values are accepted input voltages for both.
The provided power adapter is 24V 1.2A and for math are 28,8W max.
The hEX S use 6W and hAP ac lite use 8W,
6+8 is les than 28,8 and are sufficient power for both devices.
, but the mode auto is supposed to detect the power that is needed from the Hap ac Lite and provide only what is needed.
Do not invent things by supposition.
Simply you provide 24V to the hEX S, and the hEX S provide exactly same voltage (24V) to the hAP
If you provide for some reason 30V to the hEX S, the hEX S still provide exactly same voltage (30V) to the hAP
Isn't that how it is supposed to work?
Don't make any supposition, read manuals, datasheets and study how current, voltage and power work.
