  • I don’t think you have to be autistic to have a passion for something and realise that the only way you’ll pass that knowledge on is via written text.

    Before the printing press the only way to copy a book was by hand. Do you think the people doing it were odd or just pragmatic?



  • Pump the brakes. You need to find out what voltage it wants over PoE. There is NO guarantee that it is the same as the 12v input.

    Standard Poe is like 48v. Unifi used 12v and 24v Poe for a while to power their antennas and AP’s but this is not standard and they have stopped doing it. This was supplied by their special poe injectors.

    You will cause serious damage if you supply the wrong voltage to your device.

    Edit: reread your post. The negotiation protocol is to

    a. See if the device plugged into a Poe switch actually needs power

    B. Negotiate higher supply’s like poe +, ++ and in future +++.

    For a Simple PoE device the negotiation is not needed.
