Mini Rack 001: 4U PoE, Solar, and UPS K3s cluster


Description: I wanted to build a mini rack that could be picked up and transported with zero downtime. It has a UPS on the bottom that provides 3-4 hours of battery backup, can be recharged in 2 hours, and even has a DC solar input, so you can keep it running off a portable solar panel!

All the devices are powered via PoE, and ideally I will have everything hard-mounted for rugged durability (right now the Sherpa UPS is loose in the bottom, so if you shake it around like in a moving vehicle, it will likely fall out).
