Ubiquiti UniFi USW Flex Managed Layer 2 Gigabit Switch

Have used these in a couple situations where I needed to connect several POE devices and only had one cable run. It is powered by and shares POE so you can put it anywhere, no local power supply needed. Just be sure to cover your power requirements and use a suitable injector etc. Also, if you’re using an injector rather than a switch be sure to enable it in Unifi Controller.

A great outdoor rated PoE powered PoE edge switch.

These are versatile edge switches. The are great for locations that require switch power to be delivered via PoE, but also want the switch to provide PoE to other end-point devices. The Flex itself operates at maximum capacity when powered by a 60 watt PoE injector or a PoE switch that provides 802.3bt (60W) PoE to the port to which the Flex is connected. When powered this way, the Flex can deliver PoE+ power from each of the four ports, but obviously with a 60W maximum power budget overall. Do not confuse this with the Flex Mini which costs $29 and overs no PoE power to other devices. If you buy the Flex Utility Box for this switch. It comes with a PoE injector inside the box, but that injector is "power only". There is no "data in" port on it, so you lose on of ... MoreThese are versatile edge switches.

Fantastic managed switch for PoE peripherals

I can't say enough good about this little switch. It offers per power management for data and power use. Yes you can order it to power cycle any particular port to reset those hard to reach AP's or cameras. It measures the PoE consumption of each port as well as the total draw from the PoE uplink. It's sealed against weather and mounts in harsh environments like attics and garages. Integrated into the UI software it's also helpful to track down problems with devices connected through it. If you have a router, you can also run VLANs through it to, for example, tap off a dedicated PoE ethernet line for a security camera and turn it into a general purpose trunk line for regular devices like solar inverters or AP's, and then VLAN the camera port back to the dedicated ... MoreI can't say enough good about this little switch.

Great remote switch for POE devices.

Mounted this in my attic to power two Unifi access points and have two additional ports for future security cameras. I added a POE injector upstream to provide the necessary power since I was using an older POE switch upstream that would not run the switch and all the devices that I would like to connect to it. Easy to setup, nice cover for the ethernet ports for cable routing. ONE ISSUE: I needed to specify POE Injector as the power source in the Unifi network control. The switch did not automatically detect the POE injector and could not provide power from more than one port. Once I updated these settings, everything worked great.

Outside of the Box Thinking

This is a versatile switch that can be POE powered and provide POE output which works in the Unifi ecosphere. It provides for those out of the box thinking type of solutions. If you use a POE+ or POE++ source to power it make sure to change the USW-Flex config setting to POE injector to get up to the 15W per port supply. Be conscience of the POE source you choose and the total power budget to ensure adequate power out to the connected devices.

Perfect for Powering Multiple PoE Devices

I had a situation where I had a PoE phone and PoE access point in the same area. Between the patch cables, power cords, and PoE injectors, it was a cabled mess. This was the solution. It eliminated the need for the injectors and let me get rid of a couple of the patch cords. There were no issues with the Ubiquiti Dream Machine Pro picking up the device for management. One good thing: the switch can be powered by various levels of PoE - the only difference is how much power is available for other PoE devices on the switch: PoE - 8W for other devices PoE+ - 20W PoE++ - 46W Right now I'm using a PoE+ port to power the switch, which in turn is supplying a UniFi Touch phone and a UniFi AC access point with no issues. Quiet, runs reasonably cool, and comes with various ... MoreI had a situation where I had a PoE phone and PoE access point in the same area.

Powered by POE and supplies POE to every port

I used this little switch to extend ethernet and POE to a separate location where I could not add another cable. I also wanted to eliminate a couple of POE injectors and instead power back from my main network switch. Works great for me. I used Ubiquity Pro Switch 24 sourcing power over Ethernet which provides IEE 802.3bt PoE++ to the Flex RJ45 input switch. The switch immediately powered up, and began distributing power itself to the output ports which are IEE 802.3at PoE+ RJ45. I use it to power a Ubiquity WIFI access point as well as a Hikvision security camera. Be sure to check that the power specs match the devices you are wanting to power as all POE is not created equal. Included components to mount to a pole, or to place on a shelf. RJ45 connectors had a ... MoreI used this little switch to extend ethernet and POE to a separate location where I could not add another cable.

RJ45 connectors had a splash shield if used to mount outside. Case is pure silky white and fits in the palm of my hand. Pretty amazing for all the features it includes. The only downside I have its connecting and disconnecting RJ45 connectors is more difficult than normal due to the splash shield, but for me, this is a 1 time activity. Nice feature if outdoors

Very flexible and powers cameras & access points with ease.

Using my USW-16-150W switch to give the USW-Flex 20W budget for POE and using the other 4 ports for Dahua cameras (non PTZ) and UAP-AC Pro access point. Still has some overhead power available. Does get hot, so will see if that shortens the life any in the garage. Has a metal back plate for mounting, which may help some with the heat.

Works as Advertised

The UniFi Switch Flex 5-Port that I received works exactly as advertised: It is small and unobtrusive, integrates seamlessly with my existing UniFi environment, provides PoE power to attached devices depending on how much power is provided to it, is itself powered by PoE so it can be installed in remote areas, operates in ambient temperatures higher than the US-8-60, and frees up ports on my main switch. I am powering it with a US-8-150, and it is in turn powering 3 UVC‑G3‑AF bullets. It has been in operation for about a month. We'll see how it handles 120-degree Phoenix summers in enclosed, un-air-conditioned spaces soon enough. The only downside that I've noticed so far is that unlike the US-8-150, the USW-Flex doesn't seem to support port security at all (at ... MoreThe UniFi Switch Flex 5-Port that I received works exactly as advertised: It is small and unobtrusive, integrates seamlessly with my existing UniFi environment, provides PoE power to attached devices depending on how much power is provided to it, is itself powered by PoE so it can be installed in remote areas, operates in ambient temperatures higher than the US-8-60, and frees up ports on my main switch.

The only downside that I've noticed so far is that unlike the US-8-150, the USW-Flex doesn't seem to support port security at all (at least in the UniFi interface). In my particular case, it's a *relatively* minor shortcoming that can be handled upstream of this device, but it is the only reason that I didn't give it 5 stars.

just got two, really like them so far

Nice little POE powered switch, that also provides POE power to the output ethernet ports. Just be sure you know the maximum watt per port on the switch feeding the power to this switch, and be aware that this switch itself uses some power (around 5w if I recall correctly). Also, keep any eye on the maximum watt usage of clients you connect, e.g. my security cameras use roughly double the power when they turn on IR lights at night. (~3w daytime, 5+ in the dark) A nice addition to the Unifi collection, plug in, adopt, we're online, and with information about power use on every port, etc.
