The power flickers at 11pm on a Friday. Your gateway reboots. Your cameras go dark. Your phone system drops calls. By the time the grid stabilises, you've lost an hour of business and a customer's trust. The UniFi Network Mission Critical switch is built for exactly that moment. A 368Wh lithium-ion battery sits inside the unit and keeps eight PoE devices running through the outage. Two 230V AC outputs feed your gateway and modem so the uplink stays alive too. Four GbE PoE+ and four GbE PoE++ ports cover your cameras, phones, and access points. A DC terminal block lets you bolt on an external 48V battery if you need even longer ride-through. Manage it from the UniFi Network app (v6.2.26 or later). Add to cart before the next storm rolls through
