About this deal

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. 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. 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. 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. 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

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.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. 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. 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.

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. You may choose to restrict the collection or use of your personal information in the following ways: Have lower fan noise — the non-pro models are fanless. The pros have fans, but are quieter than the 1st generation models.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. 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

Do not have a serial console port. All management has to be done over Ethernet in-band. (EdgeSwitches still have console ports!)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. To break the dozens of models into understandable chunks, the first thing to cover is the 1st vs. 2nd generation. An easy way to identify which generation they belong to is what their model name begins with: We recommend that you protect your networks from harmful outdoor environments and destructive ESD events with industrial-grade, shielded Ethernet cable from Ubiquiti. For more details, visit: ui.com/toughcable 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. 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.
