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. A factory reset is useful for a creating fresh setup of a UniFi Console, or device that was already configured in a managed state. Restoring with the Reset Button Selecting this option will unmanage the device from your UniFi Console and restore the device to a factory default state. UniFi Consoles The Ubiquiti UniFi Switch 16 150W delivers robust performance over its 18 independent switching ports. Two SFP ports offer optical connectivity, and 16 Gigabit Ethernet ports of auto-sensing IEEE 802.3af/at or configurable 24V passive PoE allow you to simplify your infrastructure. 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.

We use the Ubiquiti equipment at work (mainly the access points) and have been very impressed with how they are built and their reliability. We have a couple hundred access points in service now for three years, only one died and was replaced under warranty. I mounted it, plugged it in to power and the other switch I had. By the time I got upstairs, the controller already found the new switch.

Key Features

The Ubiquiti US-16-150W UniFi switch provides fiber connectivity options for easy expansion of your networks. Each Ubiquiti US-16-150W UniFi switch model includes two SFP ports for uplinks of up to 1 Gbps for network expansion and uplinks. UniFi Controller If you keep having problems with the installation of the firmware you can also try to install it your self directly on the device. To do this we are going to access the device using SSH. Its enterprise level equipment, so you pay a little more than consumer, but it is in reach of a homeowners budget. I highly recommend it.

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 Passive 24V and 48V PoE — Ubiquiti’s standard, mostly used on EdgeMAX, AirMAX, and older UniFi devices 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.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. Note: This can only be done by the account owner and requires them to have previously signed into the mobile app while the device was managed. 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. 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. I have been working a lot with Unifi devices and sometimes you just got one of those devices that just won’t adopt. You may get an error that a firmware update is required or you can’t simply find the device in the controller.

USW-Flex — When using PoE passthrough ( Note: this was upgraded to 802.3at PoE+ in a firmware update) 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: 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.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.

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. Wait for the device to fully boot, the led will turn dark blue (or stay white if it wasn’t adopted before, approximately 5 minutes max) This Ubiquiti US-16-150W UniFi switch offers sixteen (16) PoE Gigabit Ethernet ports of auto-sensing IEEE 802.3af/at or configurable 24V passive PoE to simplify your infrastructure. By default, the Ubiquiti US-16-150W 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 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.Do not have a serial console port. All management has to be done over Ethernet in-band. (EdgeSwitches still have console ports!) 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.
