Your ISP blips at 4:58 pm on a Friday and your whole office goes silent. Calls die, video conferences freeze, someone's about to lose a client because the internet blinked. You don't need one gateway praying the link holds. You need two. The UniFi WAN Switch (SFP+) links two Shadow Mode High Availability gateways to a single ISP through dedicated 10G SFP+ ports, so when one path stutters, traffic rides the other without your team noticing. Two AC power inputs mean a single adapter failure doesn't take you offline either. One GbE management port keeps everything visible in UniFi Network. You plug in the SFP+ modules, point two gateways at it, and your connectivity stops being a single point of failure
