Spec's here https://www.cnet.com/products/brocade-fastiron-gs-648p-switch-48-ports-managed-desktop-series/specs/

Has been my staple home network switch for over a year but after moving into a new house, the cabinet location backs on to the ensuite and due to the noise, the wife says it has to go!

Looking for $140 which is a pretty good price for a 48-port gigabit switch with PoE on all ports. Unit is 2RU, quite deep and heavy so if you need me to ship, I'll have to get a quote.

I've wiped the username/password from the webpage and CLI to you can tinker to your hearts content. Most programming is done via the command line.
