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 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. Have lower fan noise — the non-pro models are fanless. The pros have fans, but are quieter than the 1st generation models.

Build and expand your network with Ubiquiti Networks® UniFi® Switch, part of the UniFi line of products. The fanless UniFi®Switch delivers quiet yet powerful performance with its 10 independent switching ports. Sharing a total of 150W PoE, eight Gigabit Ethernet ports offer 802.3af/at PoE+ or 24V passive PoE and two SFP ports offer optical connectivity. This Ubiquiti US-8-150W UniFi Switch features eight PoE+ Gigabit Ethernet ports of auto-sensing IEEE 802.3af/at or configurable 24V passive PoE to simplify your infrastructure. By default, this UniFi Switch automatically detects 802.3af/at devices so they automatically receive PoE. For 24V passive PoE devices, manually enable 24V passive PoE using the UniFi Controller software. Fiber Connectivity 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.USW-Flex — When using PoE passthrough ( Note: this was upgraded to 802.3at PoE+ in a firmware update) EdgeSwitches are older, more traditional managed switches, with command line (CLI) and individual web interfaces for configuration. EdgeSwitches also have optional integration with the UISP software controller. The newer UISP-branded switches are tied closely to the UISP software, have no web interface, but still offer a CLI for manual configuration. I cover EdgeSwitch and UISP hardware briefly below, but I cover them in more detail in my UISP Switch review. 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.

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. The UniFi ®Switch features auto-sensing IEEE 802.3af/at and 24V passive PoE to power multiple devices on the network. The Ubiquiti UniFiUS-8-150W is a fully managed 8 port PoE+ Gigabit switch, delivering robust performance and intelligent switching for growing networks.The US-8-150W is afanless UniFi switchwhich delivers a quiet yet powerful performance.

Passive 24V and 48V PoE — Ubiquiti’s standard, mostly used on EdgeMAX, AirMAX, and older UniFi devicesEight Gigabit RJ45 ports offer different power output options: auto-sensing IEEE 802.3af/at PoE/PoE+ and 24Vpassive PoE, and two SFP ports provide optical fibre connectivity options to support uplinks of up to 1 Gbps. 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.

Do not have a serial console port. All management has to be done over Ethernet in-band. (EdgeSwitches still have console ports!) Higher PoE budgets. The 2nd generation non-pro models are fanless and have very limited PoE budgetsWe require this information to understand your needs and provide you with a better service, and in particular for the following reasons: 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.

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. 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. 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 Ubiquiti US-8-150W UniFi Switch provides fibre connectivity options for easy expansion of your networks. This Switch includes two SFP ports for uplinks of up to 1 Gbps, so you can directly connect to a high-performance storage server or deploy a long-distance uplink to another switch. UniFi Controller Going forward, Ubiquiti seems to be drifting away from the EdgeRouter and EdgeSwitch line, instead focusing its efforts on the new UISP devices, such as the UISP Switch and UISP Router, no doubt with many more to come.So far, Ubiquiti hasn’t really done this since, there have only been two switches released which looked identical and had corresponding UniFi and EdgeMAX editions. There were these switches here and the UniFi Switch 16-150W, which also had an EdgeSwitch version. At that time, Ubiquiti had the UniFi AC Pro which was powered by 802.3af/at as well as the UniFi AC Lite and the AC LR which were powered only by 24v passive. In the years after, Ubiquiti made the decision to standardise it’s use of PoE in the UniFi line to autosensing PoE only and leave the passive PoE to the airMAX and WISP line of devices. 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. Have a small touchscreen on the left side of the device, like the UDM-Pro. This screen shows stats and info about the device, and the network it is on. They also integrate with the UniFi AR feature, which lets you use a phone to virtually see what is connected to each port.
