    What is the autonegociation you’re talking about here ? I never owned a POE switch, I, of course, don’t need all the port, it was the cheapest POE switch I could find near me, everything else is like 250€ or more, or 150 for unmanagable. It won’t be ON often for the moment, I just wanted a POE switch to have fun with wifi AP and in the futur IP cameras!

      Autonegotiation allows two devices, such as switches or network interface cards, to automatically exchange information about their capabilities and configure the best possible connection settings, like speed and duplex mode. This enables devices to establish a link with optimal settings for both. Without it, this needs to be done manually

        Not PoE+ so no autonegotiation

        Yeah I already knew what autonego is, but this bit I didn’t understand, why POE/POE+ would affect auto nego ?

          If I had to guess, negotiating POE voltage. Some stuff uses nonstandard voltage like some older ubiquiti gear

          Auto negotiation is not an L2 process. It is a physical layer process that is performed before a CDP or LLDP packet can be transmitted.

            He’s not talking about speed/duplex auto negotiation. He’s talking about automatic power negotiation.

        In this case the 3750G is a standards based PSE using 802.3af. It should not have any issues powering modern network equipment up to 15.4W
