I was given some Extreme Networks Summit X440-48P/24P switches by a business that was going to toss them. Need help factory resetting one with a password.

Basically, I have been trying to follow stuff I've found searching online, and can't figure out how to get past the password prompt to run the "unconfigure switch all" command (and does this actually wipe any and all existing information on the switch? For what it's worth, I did get connected to one and was able to run this command. I'm kind of proud of that lol).

I am new to this stuff and I'm absolutely stuck. I have been giving it an honest try and googling my ass off though, if that counts for anything. I just don't know what I'm doing and I'm getting nowhere. I need some help to get me sent in the right direction.
