Ubiquiti US-16-150W 150 W 16 Port UniFi PoE Switch

Product Information

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. 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.

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. Read full review

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: Most UniFi switches operate at layer 2, meaning they can handle VLANs but cannot act as a router. The 2nd generation pro and enterprise UniFi switches have some layer 3 features such as static inter-VLAN routing and DHCP, but they require a separate router or firewall for everything else. UniFi L3 switches can’t compete with a true enterprise product from a vendor like Cisco or Juniper. UniFi switches are a fraction of the price and don’t require licensing, so they compete in different markets. As with all network design and purchasing decisions, what matters most is your budget and your use case. 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!)

Basic layer 3 features like static routing (supported as of firmware version 4.3.13.11253) and inter-VLAN routing.

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. 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 24V and 48V PoE — Ubiquiti’s standard, mostly used on EdgeMAX, AirMAX, and older UniFi devices 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. 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.

Ubiquiti calls them “Gen2” but I am going to call them 2nd generation. Whatever you call them, Ubiquiti’s newer UniFi switches split things into a few tiers. There are models which replace the 1st generation switches, and the higher pro and enterprise tiers. 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. 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.Have lower fan noise — the non-pro models are fanless. The pros have fans, but are quieter than the 1st generation models. 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. 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)

I adopted it and upgraded the firmware. It took longer to unbox and mount it than it did to set it up. 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. 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: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
