1 Project Scope
My parents' house is widely equipped with Mikrotik routers and other passive PoE powered hardware. So a centralized power distrution seems reasonable. However, passive PoE injectors like the one from Intellinet have one considerable problem:
They use a powerful PSU, capable of delivering a high current to a single port in case of a short circuit on the cable, inevitably causing a fire.
So I wanted to have a PoE injector that has a per-port fuse. I was not ale to find such a device on the market, so I built it myself.
Additional features:
- Web Interface
- Current port switching status
- Fuse status
- Syslog interface
- Switching events
- Fuse falure events
- External powering (24V) from UPS / Battery
