Ubiquiti - USW-Ultra

This switch has made a huge inprovement in cleaning up my network rack. The POE+ output is reliable and consistent. The switch was easy to set up, but make sure you have a POE power suppli that is properly rated as this switch can pull up to 45 amps. At over $100 this switch is an expensive piece of kit. However the seamless integration in the ubiquiti ecosystem, the high quality, and appearance make it well worth the expense.

This switch is powered via POE, if you want to run POE devices down stream, you need to ensure you are supplying enough power. My main switch didn't quite produce enough so I had to use a separate POE injector.Outside of that, it works fantastic. Any issues I might have would be my own dumb fault versus the product's.Like all Unifi products, as soon as you plug it into your network, the controller will see it and present it for adoption. Adopt it and push any VLAN changes you may need. Mine is splt between cameras and additional accesspoints.

Easy to install didn’t had a problem figuring out how to operate

No power supply. It is understandable that some customers may not use it because they use PoE. However, the description needs to say it does not include the DC power supply. I would have spent a few dollars more to buy one, but there was no way of knowing without reading other reviews.The images show where it's plugged, and the description of what's contained in the box is "hardware kit." It's insufficient information. Now my install is delayed another day.

Aside from the price, this thing rocks! Can centralize power to conditioned, battery-backed rack while still providing POE to far-flung places in the house without too much wiring mess.

Works great, this switch doesn’t come with a power cord (and you can’t buy a power cord after from them separately) so if you need P.O.E 60 watts you need to buy the other switch ( ubiquiti usw ultra 60w) or use an injector to make it work. I hope this helps you

This is one of Ubiquiti's relatively new network components. When I ordered this, it had been a few years since I'd built a UniFi network, and this is one of several components that made the job easier and justified the decision to go with UniFi over competing systems, particularly TP-Link Omada.The first thing you might wonder when looking at this item's description is what, exactly, is it for? When was the last time you needed a PoE-powered PoE mini switch? (Personally, I had NEVER needed such a switch before.) The answer is that Ubiquiti has invested heavily in security systems; not just in producing backbone networks for security systems, but in producing the recorders, cameras, gate entry systems and other components as well. Most components in such systems require Power Over Ethernet (PoE), so, not surprisingly, Ubiquiti offers many PoE switch options in their UniFi line. But it's not always convenient, easy or even possible to run cables directly from the network closet to where some of the cameras and other system components need to go, and there aren't always power outlets or outlet boxes that one can easily tap for those components, either. I am often called in to help a surveillance system specialist with such networks, and I'm sure there have been PoE-powered PoE switches available from low-voltage supply companies for such purposes for years now. However, for network architecture, system monitoring and control purposes, it's a welcome bonus to be able to have a managed switch option that integrates with your software-defined network setup. And that's the niche that this switch fills.I recently completed a project with my low-voltage & surveillance partner that presented some unusual problems. The building, actually a complex of several buildings that had been essentially fused to one another, is particularly difficult to pull cables through, so to keep costs under control, there was a strong incentive to use existing runs as much as possible. There were also no power sources convenient to where many of the cameras had to go. So, this project also relied heavily on satellite network racks tucked into whatever spaces were available. I bought three of these PoE-powered mini PoE switches - actually, they're PoE++ powered PoE+ mini switches - to go in places where we had a single Ethernet cable available that we could connect to a PoE++ switch port, but where several cameras or wireless access points needed to go.In describing the Ubiquiti UniFi USW-Ultra as a PoE++ powered PoE+ mini switch, what I mean is that it accepts a PoE++ power feed of up to 60W DC and can then provide data and power to up to 7 PoE+ devices. I bought the basic UniFi USW-Ultra model, which doesn't come with a power supply. If you power it from a PoE++ main switch, such as the UniFi USW-PRO-24-POE, then the USW-Ultra can draw up to about 60W from the main switch and use it to power up to 5 PoE or PoE+ cameras; the switch itself needs 19W to run. The actual number for you will depend on the power draw of the cameras you use. In our case, we only needed to power 2 or 3 cameras per switch, and, in one case a UniFi U6+ wireless access point, each drawing about 10-12W. If you need to power more than that, you'll need the USW-Ultra-210W version, which comes with a 210W AC adapter.We did need to place one of our switches in a place where it was not possible to pull a cable from the PoE++ main switch, and we needed to daisy-chain a second USW-Ultra to it, so we really needed that PoE++ power input. Ubiquiti's only in-brand solution to this dilemma would have required me to have the low-voltage electrician remove the USW-Ultra that he had begun to install so that I could exchange it for a USW-Ultra-60W or -210W. I didn't want to go to all that trouble or expense, but, fortunately, I was able to find a 3rd party 60W PoE++ injector to power the switch.For the most part, my UniFi network set up easily enough with the UniFi Network Application. However, we ended up making some network architecture changes mid-stream, which had the unfortunate result of requiring a local IP addressing change. One of our USW-Ultras refused to accept the change and communicate with the UniFi Controller (referring, in this case, to the computer running the UniFi Network Application). It took a physical power-cycle to get it to accept the change and adopt.I'm happy with the USW-Ultra switches so far, although I docked it a star for that reconfiguration issue and Ubiquiti's inflexibility in not offering an AC adapter or PoE++ injector for purchase separately. I always do my best to plan ahead, but change requests are a common phenomenon!

Great product, but then again, everything Unifi puts out has been stellar.
