Unifi Switch Flex | USW-Flex

Product Information

Putting the L2/L3 differences aside, the 2nd generation pro models also have some other advantages over the non-pro UniFi switches. 2nd Gen Pro models add Port managed PoE switch with (1) 802.3at/bt (PoE+/PoE++) input port and (4) 802.3af (PoE) Gigabit Ethernet ports If you are planning on using PoE passthrough on switches like the USW-Flex, or access points like the In-Wall-HD, you should supply them with the higher-wattage PoE+ or PoE++. Devices with PoE passthrough will usually function when fed with standard 15W PoE, but will not reliably power downstream devices unless they receive their maximum rated power input. For example, the USW-Flex can provide 8W with PoE in, 20W with PoE+ in, and 46W with PoE++ in. I’ll use the PoE, PoE+, PoE++ names as shorthand. It is important to consider the type of PoE you need for your devices, and to make sure that you have enough PoE budget on your switch to power all your devices. Otherwise, you will need to rely on separate power injectors. PoE Passthrough Ubiquiti calls them “Gen2” but I am going to call them 2nd generation. Whatever you call them, Ubiquiti’s newer UniFi switches split things into a few tiers. There are models which replace the 1st generation switches, and the higher pro and enterprise tiers.

EdgeSwitches have an optional web interface overlay called UISP, which is similar to the UniFi controller. UISP is limited when it comes to EdgeSwitch configuration, and it doesn’t have every option that the device’s individual web GUI or CLI has. Think of UISP as an easy way to monitor all of your AirMAX, LTU and EdgeMAX devices, rather than a single interface for configuring everything like the UniFi controller. Please note: This product does not come with a PoE injector (sold separately, see accessories tab).

XG 6 PoE (Gen1)

The USW-FLEX will now allow for a 46W total power output rather than the 8W when using the default settings. No 802.1X (Not a huge deal because I can enable multi-host on the upstream switch, which limits the danger-zone to just the other client ports on the switch.) USW-Flex — When using PoE passthrough ( Note: this was upgraded to 802.3at PoE+ in a firmware update) EdgeSwitches are more flexible and capable, and are a better fit for network operators, WISPs, managed service providers, and other more advanced networks. If you need features like link aggregation, TACACS+, RADIUS, 802.1X, MAC filtering, ACLs, or static routing, you’re better off with an EdgeSwitch than a UniFi switch. UniFi switches support many of these features, but are often less configurable, poorly documented, and less reliable.

Passive 24V and 48V PoE — Ubiquiti’s standard, mostly used on EdgeMAX, AirMAX, and older UniFi devicesPoE passthrough is when a PoE device can receive power and also pass PoE to another downstream device. A common example would be a 24 port PoE switch, feeding an In-Wall-HD access point, with a video camera connected to the In-Wall-HD. The key part is that all three devices are drawing their power from the 24-port PoE switch. In situations like that, you need to be especially careful about what PoE support your switch or voltage and amperage of your PoE injector. The UniFi Switch Flex Mini uses only a maximum of 2.5W. For your convenience, it can be powered by 802.3af/at PoE or a 5V,1A USB-C power adapter(european only)
