Ubiquiti UniFi Flex Mini 5-Port PoE Switch

Product Information

The Ubiquiti UniFi USW-16-PoE Switch is a configurable Gigabit Layer 2 switch with 16 Gigabit Ethernet ports including eight auto-sensing 802.3at PoE+ ports, and two SFP ports. 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. Mode B works by having two dedicated pairs of wire (Pins 4,5+ and 7,8-) dedicated to carrying power, and the other two pair for data. As PoE adapters (injectors) take standard data Ethernet and 'injects'power into the cable, they more often use Type B to power devices. Thus Mode B is sometimes referred to as Midspan.

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. Higher PoE budgets. The 2nd generation non-pro models are fanless and have very limited PoE budgetsThe 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.

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. 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: 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. This article will cover the basics of Power over Ethernet (PoE).PoE streamlines the process of powering and providing data to a connected device by sending electric power over the Ethernet cable. There are different PoE types, standards modes available. This article will focus on the differences between some of the PoE types and standards that are relevant to Ubiquiti equipment. Table of ContentsDo not have a serial console port. All management has to be done over Ethernet in-band. (EdgeSwitches still have console ports!) After that, if you want to view the switch’s status or change some simple settings, you can use its little touchscreen, which is fun and helpful. 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!

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. Passive PoE A fixed output voltage is provided and there is no negotiation performed. Example output modes are 24V, 48V and 54V. The main point I’m trying to make here is that if you expect a UniFi switch to be your only layer 3 device, you’re going to be disappointed. Adding layer 3 at the switch level usually doesn’t make sense in small to medium sized networks, and I wouldn’t recommend relying on UniFi layer 3 switches in general. If you’re working on a large multi-building network with high requirements, UniFi may not be the best fit. I’ll cover this in more detail if I ever get around to finishing my USW-Enterprise-8-PoE review. I tried that out with the switch and could use its more advanced features, including port settings and bandwidth management, as shown in the screenshots above. However, none of these extras is essential for any home. Active PoE The voltage that the Powered Device (PD) needs is negotiated. Example output modes are IEEE 802.3af, 802.3at and 802.3bt.

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. Note: Please refer to model-specific datasheets found on the UI Store for more detailed information. PoE Adapters UniFi switches help you power, connect, and process traffic across all of your devices. Since each deployment’s size and layout are unique, we offer several distinct switch categories meticulously designed to optimize any network in any environment. We’d like to explore these categories further to help you identify the model(s) that will deliver the most value for you. Deciding between UniFi, EdgeMAX, UISP, or some other brand depends on your needs. The right solution varies with what kind of network you are trying to build, and what features you need to accomplish that. If you are comfortable with command line configuration and have complex needs, another vendor is probably a better option. This guide focuses on UniFi switches, but it’s worth noting some EdgeSwitch models are the same hardware as the first generation UniFi switches, with an EdgeOS CLI and UISP instead of the UniFi controller. The newer UISP switches are not as mature, but are worth considering if you want your switch to tie into the UISP NMS and UCRM software.
