How to reset the switch, no one knows anything about it, and does it ignore the attempt to connect by rsk?

Question

Computer networks

Good afternoon. I got it in the teeth on an old LinkPro smi-2404-m1 switch. There is no data on it at all. They asked me to try to reset the password or the entire configuration on it. Technical support is very intractable, attempts to connect via telnet, through a browser on the factory ip or which port the switch ignores. Are there any other options, or is it a brick now?

And they also do it on their devices Factory reset button.

Answer 2

And in a stupid way through it there is an Internet at all? For example, plug a PC and a wan cable from the provider into any lan connectors.
