Added capacity for an extra six hosts on my LAN and now most of my network infrastructure supports 2.5Gbps ethernet speeds. And my janky rack is obsolete now.
The equipment is four TP-Link TL-SG108-M2 ethernet switches which I got from Amazon.
Oh, and I should probably mention that the TP-Link switches come with piddly little adhesive feet, but I didn’t use them, I got some of these big honkin’ ones instead: 25x Rubber Feet Pads Self Adhesive Isolation Feet Speakers Foot Shock Absorption. My logic is that more space between switches equals better cooling.
