Ubiquiti Networks Unifi 48Port Pro Switch Gen2 (USW-PRO-48-POE)

Great supervised 48 POE… will buy another one soon.

The SW‑PRO‑48‑POE is an absolute beast of a switch. From the moment it’s racked, you can feel the build quality and engineering behind it. Performance is rock‑solid, PoE delivery is consistent across all ports, and the overall reliability is exactly what you want in a core switch. What really sets it apart, though, is the ease of management. The interface is clean, intuitive, and makes monitoring, configuring, and troubleshooting incredibly straightforward—even across multiple sites. Whether you’re deploying a handful of devices or an entire building’s worth of APs, cameras, and endpoints, everything stays organized and simple. And the scalability is outstanding. This switch slots perfectly into growing environments, letting you expand without rethinking your entire network design. It’s built for today’s needs but clearly ready for tomorrow’s load. If you want a switch that delivers enterprise‑grade performance without the enterprise‑grade headaches, this is the one.

I definitely recommend this product, Excellent!!!

Everything was in excellent working condition and the shipment of my 15 switches was fast and everything arrived in top notch condition! Hope to do business again!

I waited for a while for this to be released and decided to purchase in May 2019 (I figured the early bugs would be worked out by now). Wrong. The first one I ordered reported overheating after a week of using it. Installed in a rack with plenty of ventilation, etc. Looking closer in the shell (swctrl env show), the PSU temp would sometimes hit 127C, but usually hung between 81C and 90+ C. I never had any issues where it rebooted, but again the controller and the display on the switch reported it overheating. I ordered a second unit from Amazon figured I had just one bad unit. The second unit I received happily shows 50C without overheating, BUT, don't believe it!! Again, running "swctrl env show", the PSU showed a temp of -128C which is impossible, so the sensor is obviously bad and who knows what temp is really was operating at. I tried to contact support but quickly gave up with them when the asked silly questions like, are the power cables firmly attached. Please...give me a break. I like the UniFi Wifi line, but the UniFi switches are too immature. If you search online, you'll see other examples of their switches overheating. I'm returning both and going with another Netgear switch which I know will work as I've had them in production for the past 10+ years without any drama. I really wanted to like the UniFi switch but it's a train wreck...don't bother, go with something reliable.
