The Zyxel CX4800-56F is a high-density L3 aggregation optical switch in which the company pioneered the use of 100G ports: 8 QSFP28 100GbE uplinks complement 48 SFP+/SFP28 slots with 10/25gbe support, forming a single 56-port stack for traffic aggregation in campus and data centers factories. With a pass-through switching matrix of up to 4 Tbit/s and forwarding speeds of up to 2 billion packets per second, this switch confidently closes scenarios of highly loaded highways, where not only ...

We have a rather interesting class of L3 switches in front of us: multi-gigabit PoE models with a relatively small number of ports, an average PoE budget by modern standards, but 10-gigabit uplinks. They are interesting because the manufacturer has placed 2.5G PoE + 10G in a compact 9-inch rack housing with a silent fan, and such a switch can be installed at home, in a 1-room office, under a false ceiling or in narrow telecommunication cabinets. We have a rather interesting class of L3 ...

We will take two switches: the Taiwanese brand Zyxel and the Chinese counterpart from a little-known manufacturer and look at the design differences and what they affect in order to answer the question - does it make sense to overpay for design features? It's no secret that almost all modern electronics are manufactured in China, even if they are developed in the USA, Europe, Japan or Taiwan – the Chinese have not only learned how to do things efficiently, but have also grown such IT giants ...

This is a 28-port switch, in which 4 ports are gigabit optics for Uplink, and the remaining 24 ports are 1-gigabit RJ45 PoE with a total power budget of 370 watts, and each of these ports can work both in 802.3af mode (up to 15.4 watts) and and in the mode 802.at (up to 30 watts). When integrating into the project, some features of this switch should be taken into account. Level 3 switches with PoE support are usually used to build enterprise Wi-Fi networks and video surveillance systems. And ...

The free and open source software market has made a tremendous leap forward in recent years, so today thousands of companies are using FOSS instead of public clouds. You don't have to buy a huge server to run your micro-cloud, you can set up a lot even on a desktop NAS. Since about 2015, in our NAS reviews, we have focused on the fact that a modern file server for a small company is primarily the services it provides: advanced collaboration functions, file sharing via the Internet, video ...

This L3 layer switch has 4 x 10-Gigabit SFP+ slots, 1-Gigabit PoE+ ports for the main fleet of devices, NVR/VoIP optimized interface, support for Nebula cloud service and multi-Gigabit PoE+ ports for Wi-Fi 6 access points. That is, Zyxel has added a maximum of functions to make it the most versatile. In the Zyxel hierarchy, the XGS2220 series refers to access switches, that is, to the lowest level that serves end devices and access points. We are used to the fact that cheap maintenance-free ...

This model shows that even a small 2-disk desktop NAS can pleasantly surprise with storage capabilities: up to 4 NVME SSDs and up to 16 hard drives when using cards and expansion shelves. The ability to configure layer-by-layer storage and run applications in containers in a compartment with a 2.5-gigabit network makes it an excellent choice for a modern office with remote access and Wi-Fi 6. I already described the concept of a modern office in which all employees work remotely and only ...

PDUs with remote disconnection of sockets and groups of sockets, which are often called switchable PDUs, provide remote control of sockets and groups of sockets, allowing operators to quickly overload hung devices, block their activation, turn off excess power at peak loads and balance the load between phases in 3-phase networks by monitoring and disconnecting sockets. PDU (Power Distribution Unit), they are also power distributors, or power distributors, sometimes socket blocks, but this is ...

Technologies are so advanced today that there are many tools for monitoring server racks and the entire computing infrastructure of a small enterprise. These systems also allow you to optimize energy use, manage backup power and control cooling. A server rack is a miniature ecosystem with its own climate, its own electrical part, as well as its own security and protection facilities. But how to ensure the proper functioning of the rack and early troubleshooting? The solution is monitoring ...
