[Skunkworks] 24-port PoE Switch /Passive PoE Recommendation

Hello Skunkers, Does anyone know of an affordable 24-port PoE/Managed switch capable of suppying 24V/48V on all it's ports? I'd like to power 16 powered devices each requiring 48V at the port, besides another 3 devices each requiring 15V - all from the same switch if possible. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 "I can't hear you -- I'm using the scrambler."
