Hello, I am running multiple POE devices on PI4, how to use them without a network.

I have currently using the PoE switch and access the network cable to assign an address to the PoE device.

    Hi yimu,
    I'm not entirely sure what you mean by "how to use them without a network." Once the PoE devices turn on, they get their IP addresses assigned automatically (assuming you have DHCP enabled on your router). All you have to do then is to scan your LAN (Local Area Network) using nmap for example.
    But if you want to use them without a router, in which case the DHCP request will fail, devices will fall back to static IP 169.254.1.222. You will then need to assign your PC to be in the same network, eg. IP: 169.254.1.10 and netmask: 255.255.0.0. To test the connection, you can ping the devices.
