It does state clearly that the SRW224G4P switch will support 7.5W over 24 ports or 15W over 12 ports.
The Mikrotik RB433, if this is your product, i had to guess, the other units at Mikrotik seem to draw more wattage, so i just compared this unit...
Seems to have a spec which I copied from the datasheet "Power consumption ~3W without extension cards, maximum – 25 W, 16W output to cards"
In terms of support for the POE standard, the datasheet previously mentioned states;
"Power options Power over Ethernet: 10..28V DC (except power over datalines). Power jack: 10..28V DC. Voltage monitor." No where does it state 802.3af compliancy.
Does your AP have the entension cards ?
Need more information at this point, but to answer your question, the switch will support 7.5W over 24 ports or 15W over 12 ports.
