Unifi Switch Flex | USW-Flex

Product Information

One limitation of the regular second generation switches is their limited PoE budget. PoE budget refers to the total amount of power available for all PoE devices. Since the non-pro 2nd generation models are fanless, they also have smaller power supplies, and a smaller PoE budget. No UniFiOS CLI access or SCP file upload access. Can only get to BusyBox shell. (Not a huge problem, but sometimes it's handy to be able to rescue a switch at the CLI without having to do a full-on factory reset.) Managed and configured by the UniFi Controller or UniFi Mobile app, the UniFi Switch Flex offers basic Layer 2 switching protocols and features. The UniFi Controller and mobile app allow admins to configure and monitor virtually all of the switch features using a graphical user interface from anywhere. It’s also worth pointing out that PoE devices don’t always consume their maximum rated power draw. The spec sheet will specify the maximum amount the device can use, but during normal operation they won’t use that much. For example, the U6-Pro requires 802.at PoE+ or 48V passive, and maxes out at 13W. During normal use it usually consumes around 5 to 7 watts of power. PoE+ devices like the U6-Pro will usually operate with 802.3af input, but they will be unreliable. It’s never a good idea to push past your budget, feed a PoE+ or PoE++ device with a lower tier of PoE, or supply the wrong voltage. Always follow the recommended input power, and never provide less the required power or a different voltage.

You can find a step by step set of instructions on how to go about telling the controller that this switch is powered by an injector below. Please Note: This product does not come with PoE injectors included, however, you can select our PoE injector kits from the accessories menu. Ubiquiti UniFi USW Flex Mini 5-Port Layer 2 Gigabit Switch - EU Power Supply (USW-Flex-Mini) If you want 10 Gbps ports for clients, or need a distribution switch to aggregate other switches, the XG series has a few options. Some are in the 1st generation, some are in the 2nd: The USW-EnterpriseXG-24 is a 2nd gen model, with twenty-four 1/2.5/5/10 Gbps RJ45 and two 25 Gbps SFP28 interfaces. No PoE.

Switch port status

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) 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 The USW-Flex switch from Ubiquiti has the capacity to provide a total PoE power budget of 46W but this will vary depending on how you power the device. These total power output breakdowns are as follows: A common complaint with the first generation models are their loud fans. It is possible to replace them with quieter Noctua fans, or you can throw it in a network closet and forget about it. If you just need basic L2 switching and PoE, the first generation models are still worth considering, especially if budget and availability are more important than future software support. Please note: This product does not come with a PoE injector (sold separately, see accessories tab).

PoE 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.EdgeMAX products are managed with a per-device web interface, or via SSH. These web interfaces are not as polished or pretty as UniFi, but they expose more advanced features than UniFi does. EdgeSwitches also have the full EdgeOS CLI for configuration. If you’re familiar with JunOS or IOS, you’ll be able to figure out your way around. See Ubiquiti’s CLI Command Reference user guide for more details.
