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 ...

A typical IoT attack looks like this: the device connects to a malicious Internet resource directly or through its own VPN, downloads and installs malicious code on itself, after which it begins to be either part of a large bot farm for attacks on third-party resources and use as a resident proxy, or simply spies on your network, trying to intercept anythat data, pull information from open resources or harm in any other way. It is not difficult to protect your network from possible IoT attacks. ...

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 ...

Not so long ago, Human Security revealed an entire shadow network associated with infected devices and malicious applications. Infected were not only Android TV set-top boxes, but also tablet PCs, wearable devices and even cars. Some IoT devices may even be infected with viruses or Trojans already at the stage of their production or sale, and since it is impossible to imagine a modern company without IoT today, it is important to properly protect your network. Today's world is completely ...

From the point of view of the network, a modern facility can be just one access point connected directly to the WAN from the provider, and there are enough resources on this access point to raise the VPN tunnel to the headquarters, and for NAT, and to configure restrictions for customers and for basic protection of customers and employees. No, but really, why should an expensive security gateway be built on a small facility where the network infrastructure is completely wireless? Modern ...
