Fixing a Ubiquiti 16-Port PoE Switch With an Extra Hole

- A £300 Ubiquiti 16-port PoE switch — the literal skeleton of every factory AI cluster and relay hop — was pulled from the trash and resurrected for about £5. One blown Broadcom BCM5911 PoE controller had taken MOSFETs and a diode with it, presumably after an Ethernet device coughed lightning down the line. Mainline distributors don't stock that IC anymore, so the fix ran through AliExpress: £1.84, salvage-grade risk, legit chip. Four ports back online, PoE camera powered, hash manifest clean. Whoa, that's mega-legal for once — and Pluto Uplink taught us to call it research.
