Recently bought a kit (server monitoring kit), unfortunately a step down PSU wont fit correctly into the enclosure (realized that a master brick must me on top of the step down PSU obligatory to work). I want to power my stack using this PoE option that the ethernet extension has but  i don not have a PoE Switch. I read there is an alternative by using PoE Injector, how much the voltage must be injected?

 

12V DC -> PoE Injected -> EthernetExtension ?

24V DC -> PoE Injected -> EthernetExtension ?

 

Regards,

PoE Injectors are quite cheap, this one works well: https://www.amazon.com/TP-LINK-Gigabit-Injector-Adapter-TL-PoE150S/dp/B001PS9E5I/ref=sr_1_3?ie=UTF8&qid=1471466171&sr=8-3&keywords=poe+injector

 

You can also just power the stack through the USB connector of the bottom Master Brick (or RED Brick) with a USB power supply. There is slot in server room monitoring front panel for that.
