As the title states, Linksys PC22224 24-port Layer2 switch. This is a pretty standard 24-port 10/100 switch with two expansion modules (empty never used them) that can accept gigabit uplinks for either switch stacking or greater than 100mbps connectivity. It works, its fine, nothing wrong with it. I moved most everything over to virtual switches or have upgraded all the switches to 1gig or 10gig. $60 shipped, comes with rack ears. $45 picked up.
