Ubiquiti UniFi Flex Mini 5-Port PoE Switch

Product Information

On the one hand, its 2.5Gbps ports are straightforward. On the other, I don’t have enough SFP+ devices to use the two ports simultaneously. The USW-Flex-XG is a 2nd gen model, with one 1 Gbps and four 1/2.5/5/10 Gbps RJ45 Ethernet ports. No PoE. 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. In the event of a UniFi switch power supply failure, the USP-RPS automatically supplies redundant power to the failed device. One UniFi SmartPower device can support up to 6 devices until the failed device is replaced. 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.

In the end, I had to use two TP-Link TL-SM5310-T adapters for the testing, and it was impossible to know if they caused them to perform slower than a true 10Gbps connection, as shown on the charts. Considering the uplink role, though, the SFP+ ports’ sustained rate, in my case, was still more than fast enough. Flex and Lite switches are designed to be more stylish than traditional switches so you can easily place them anywhere without disrupting your décor. These switches offer a wide range of bandwidth, uplink speed, and Power-over-Ethernet (PoE) capability. Plus, they look great mounted to a wall or sitting on your desk! The Enterprise 8 PoE is not a PoE++ switch, so if you have PoE++ devices requiring higher power draws, you’ll need a different switch, like the Zyxel XS1930-12HP. Or you can get a separate injector. Ubiquiti Switch Enterprise 8 PoE’s real-world sustained throughputs. Its SFP+ ports were tested with Base-T 10Gbps adapters.The US-XG-6-PoE has four 1/2.5/5/10 Gbps RJ45 Ethernet ports with PoE++. It also has two 10 Gbps SFP+ interfaces. The 10/100 and gigabit Ethernet cables have four pairs of twisted cables that correspond to 8 pins. The 802.3af standard established that for 10/100 Ethernet cables, only two of the four pairs of wires are permitted to transmit data, while the other two could be used for power. Of these pairs, 10/100 Ethernet only allows for the transmission of data over two wire pairs (four wires). Two methods of doing this were preferred based on the power source, Mode A and Mode B. For comparison, the Zyxel XS1930-12HP features two SFP+ ports, but its ten PoE++ ports are all 10Gbps Mulit-Gig. The table below will highlight the differences between the two.

PoE Availability and Power Requirements

One thing to note: for the best and most reliable performance, you should use one of the SFP+ ports for the uplink connection. An SFP+ to RJ45 converter is necessary if your existing network doesn’t have an available SFP+ port.All the Ubiquiti Switch Enterprise 8 PoE’s ports are on its front. Here they are when out of the box and when the switch is working. Note the two SFP+ ports and the touchscreen. Higher PoE budgets. The 2nd generation non-pro models are fanless and have very limited PoE budgets All you have to do is plug it in, and that’s it, just like any unmanaged switch. Use one of its ports to connect to the existing switch or router, and the remaining ports will work as extensions of the wired network. Note: Other vendors may refer to PoE, PoE+, and PoE++ as 802.3af, 802.3at, and 802.3bt, respectively.

Also worth noting — if serial console out-of-band management port is something you need, the first generation switches have it, and the second generation models do not. XG UniFi Switches There’s a lot to cover when it comes to PoE, so I’ll try to keep it as simple as possible. There are 4 main types of PoE to know about:

Ubiquiti UniFi 16-Port PoE Switch (USW-16-POE)

The Enterprise 8 PoE doesn’t have a built-in web user interface, nor does it work with Ubquiti’s UniFi mobile app. However, like any Ubiquiti’s business hardware — similar to those in the UniFi family — it is designed to be managed via an UniFi-OS hardware controller. The BASE-T wiring is more popular thanks to its simple design and flexibility in speed support. Some routers and switches have an RJ45/SFP+ combo which includes two physical ports of each type, but you can use one at a time.
