Brocade ICX 6610-48P
I bought this switch on ebay for for $150 back at the end of January. It's too loud for me in my workshop. I've updated it to the latest firmware and did the whole license upgrade which I will blank out before shipping, but instructions on how to get unlimited ports on it are here on STH.
it has both power supplies *( both a and b revisions) and has mounting ears.
I'm asking $130 for it +plus whatever shipping is if you don't want to pick it up in Roswell, Ga.
I replaced it with a 6450-48
