Hello, I just purchased my first house and it has a cabinet of spaghetti in the office and I don’t know what it’s for or how to use it. But it does look expensive so if I can make it useful to me then I’d like to!
It should all work as is. I'd hook up a router to it and see. You can upgrade the switches at the bottom at your leisure if you need to. But if you just moved in you probably have 1001 other things to buy. 100mb switching is probably faster than your isp connection anyway.
