I wanted to thank IdiotInCharge for cuing me in to these in another thread (which I don't want to pull off topic anymore than I already have) They are original pre-HPE MAS Aruba switches. I just ordered mine, $125 on eBay, with a 1 year warranty included at no added cost. Seems like A LOT of switch for the money. Originally I was considering trying to get 10GBase-T SFP+ adapters for it, but I guess instead I'm going to put Intel x520 fiber NIC's in both my workstation and NAS. I did some googling and found a tutorial on how to set the thing up on Youtube here. Also a guide for a fan mod if you find it too loud here. Apparently it really isn't too loud as is, but you may want to do this if its right next to you in your office. It seems to take standard PWM PC fans. The Noctua 40mmx20mm fans seem to fit perfectly. And here is another guide for VLAN's Jumbo Frames, Users and more. Apparently the web interface is somewhat limited, so for anything beyond basic layer2 stuff you'll likely need the console. The console is similar to, but different when compared to Cisco, but it sounds like people familiar with Cisco consoles can navigate it with a few educated guesses and tab completion. This seems like the used Enterprise switch to buy as a hobbyist in 2019.
