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. 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: 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.

Ubiquiti USW-24-POE Gen2 24-Port Layer2 PoE+ with 2 x - Scan

Passive 24V and 48V PoE — Ubiquiti’s standard, mostly used on EdgeMAX, AirMAX, and older UniFi devices The Ubiquiti UniFi USW-24-POE is a configurable, Gigabit Layer 2 switch with 24 Gigabit Ethernet ports including 16 auto-sensing 802.3at PoE+ ports, and two SFP 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. If you take a larger view, there are a lot of available options for switching in the UniFi ecosystem. If you don’t need multiple VLANs and a segmented network, there’s nothing wrong with grabbing a budget unmanaged gigabit switch and using it in your network. If you want to be able to use multiple VLANS and need segmentation and inter-VLAN routing, there’s enough variety in the UniFi switch lineup that you should be able to find something that fits your network. There’s also a lot of other brands out there if UniFi isn’t for you.For outdoor applications, shielded Category 5 (or above) cabling should be used for all wired Ethernet connections and should be grounded through the AC ground of the power supply. 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. 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.

Managed and configured by the UniFi Network Controller with UniFi mobile app support, the USW-24-POE offers an extensive suite of advanced Layer 2 switching protocols and features, including operation mode (switching, mirroring, or aggregate) per port. The UniFi Network Controller and mobile app allow admins to configure and monitor virtually all of the switch features in a graphical user interface from anywhere. Have lower fan noise — the non-pro models are fanless. The pros have fans, but are quieter than the 1st generation models.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.

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 support simplifies your network infrastructure and cabling. PoE ports offer 802.3af/at to power your PoE devices, such as UniFi APs and cameras. The 2nd generation Pro models feature L3 support, higher PoE budgets, and 10 Gbps SFP+ or 25 Gbps SFP28 interfaces. The USP-RPS can be used for redundant power on all models that support it. 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: 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.The Ubiquiti UniFi USW Pro 24-POE is a configurable, Gigabit Layer 2 and Layer 3 switch with auto-sensing 802.3at PoE+ and 802.3bt PoE++. The UniFi PoE Switch features fanless, silent thermal cooling*, so it can be deployed in areas where fan noise would be distracting. Note: Although the cabling can be located outdoors, the UniFi Switch itself should be housed inside a protective enclosure. Basic layer 3 features like static routing (supported as of firmware version 4.3.13.11253) and inter-VLAN routing. We recommend that you protect your networks from harmful outdoor environments and destructive ESD events with industrial-grade, shielded Ethernet cable from Ubiquiti.
