Overview of UniFi Switch GEN2. New generation



The UniFi line of equipment includes a wide variety of devices. Of course, the main product of the series is wireless access points, among which there are models from the standard “classic” - the UniFi AP series and the all-weather UniFi MESH, as well as exotic built-in In-Walls. At the same time, one of the key advantages of UniFi, of course, is the ability to control in a single interface UniFi Controller, which, in fact, is absolutely necessary for the effective management of large corporate networks. That is why, in addition to wireless access points, the UniFi Security Gateway routers and UniFi Switch switches are included in the series. In addition to optimizing the work with the equipment of its family, all switches and routers of the series are configured through the UniFi Controller, together with access points and other UniFi devices.

UniFi Switch is nothing new in itself. A series of these switches has been available for quite some time, and works great on UniFi networks. However, with the release of new access points that support higher data exchange speeds, naturally, the upgrade of the switching part of the switches themselves was required. And most importantly, some UniFi access point models, due to the increased power of the radio modules, as well as their duplication, required the use of more energy-intensive power supply - POE ++ 802.3 BT - its old revisions of UniFi switches did not support. The sum of the above reasons clearly suggested the need to update the line of switches. Which was recently done by Ubiquiti engineers. So, meet - UniFi Switch GEN2.

UniFi Switch GEN2 - changes in the series.

Immediately striking design changes, compared with the equipment of the first generation. Instead of the Ubiquiti logo, a touch screen has now appeared on the left side of the ports, which displays various service information. In particular, you can find out the presence or absence of PoE power on the ports, connection speed and other similar parameters. In terms of usability and usability, this is certainly a very true innovation.

Another change was the redesigned switch cooling system. This is especially important given the increased power distribution of PoE. With the new UniFi Switch Gen2 lineup, there should be no overheating even when using the equipment to the fullest




By the way, in the most loaded versions of the first generation switches with 48 ports and distributing PoE, the problem of overheating was sometimes observed, especially when using closed racks with poor ventilation system.

UniFi Switch GEN2 - technical features.

In total, the new line has so far included 4 models that are divided into two categories. The first category includes USW 16 POE Gen 2 and USW 24 POE Gen 2.

They differ among themselves by the power of the integrated power supply, which is 60 watts for the youngest and 120 watts for the older version, as well as an interface that includes 16 gigabit Ethernet ports for the USW-16-POE Gen 2 version and 24 ports for the USW-version 24-POE Gen 2. The first model can distribute IEEE 802.3af / at on ports 1-8, the 24-port version distributes IEEE 802.3af / at on ports 1-16. Both switches have an additional two SFP ports, allowing you to connect devices through a transceiver to fiber.


The second group also currently has two devices. These are USW Pro 24 POE Gen 2 and USW Pro 48 POE Gen 2. Here the model already has a very serious power supply, which reaches 450 watts in a model with 24 ports, and 660 watts in a model with 48 ports.

Such power supply is not accidental. These models finally support the PoE ++ IEEE 802.3bt standard, with the ability to transfer up to 60 watts of power to client equipment, on ports 17-24 for the younger and 41-48 for the older model. This standard is necessary for many modern powerful PoE consumers, for example UniFi BaseStation XG. On other ports, simultaneous distribution of PoE + 3af / at power is possible. To connect to the fiber, USW Pro models are equipped with an SFP + interface with a bandwidth of up to 10 Gb / s, the number of ports is 2 for 24 port and 4 for 48 port versions.Обзор UniFi Switch GEN2.

Another important feature of the PRO versions is the support of Power Supply Failure technology, which provides a redundant power line from an external USP-RPS unit in case of failure of the integrated power supply, thus guaranteeing significantly higher system reliability.



Conclusion.

  • Summarizing a short review of the new UniFi Switch GEN2 products, we can say that by the sum of their characteristics they are a critical update to the series of switches that will fully utilize the potential of modern Ubiquiti equipment. Key Benefits of UniFi Switch GEN2:

POE ++ support on PRO versions

    Support for redundant power supply on PRO versions

    Improved cooling

    The presence of a touch screen
