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 ...

In the corporate world, the era of Microsoft's uncontested rule has come to an end: companies are switching to Linux-based operating systems, but not every laptop promises you normal work with the Linux OS. In the corporate world, the era of Microsoft's uncontested rule has come to an end: companies are forced to switch to Linux-based operating systems, abandon Office/Office365 packages in favor of sovereign or free solutions. Starting with government agencies, this trend extends to ...

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 ...

In this article, I will show you how an ordinary office laptop at the hardware level can be protected from various kinds of attacks, especially those related to the seizure or theft of the device, and after reading it, I want you to look carefully at your corporate laptops and answer yourself – what of the above do you have? Many "security officers" do not pay due attention to the laptop hardware, considering that security is limited at the level of antivirus, group policies and ...

Zyxel reasoned this way: if the L3 functionality is already determined only by the firmware, 99% choose an access switch for the sake of port density, PoE, VLAN, Multicast, and less often for static routing, then here's the base model XMG1930, which is generally L2, but slightly L3. And if your network requires advanced L3 functions, then all this is also there, just buy the appropriate license and get the core-level functionality. You can do this at any time, even when buying a device, even ...

Zyxel has a series of simple unmanaged switches for 2.5-Gigabit networks, with 5 and 8 ports. Both have a non-blocking switching matrix for full bandwidth: 25 and 40 Gbit/s, respectively, that is, they can be used in the most loaded networks. We will review and test the 8-port model. That's how you live and don't think that the 1GBaseT standard has been exchanged for the third decade. Introduced back in 1999, it managed to acquire a lot of faster options, but it is still not going to give up ...

A story about how once a protected transformer laptop forgot the safe word and was subjected to all possible tortures in our test lab. He died, but the life in him was not extinguished. The industry of secure laptops is developing along with the growing demand for such devices from medium-sized businesses: today, on a livestock farm, in a woodworking shop, on a drilling platform, and even in a geoloc tent, everything is computerized, and the concept of IoT + Edge (read our article about the ...

Synology's new flagship enterprise segment, a dual Xeon Silver model with 24 SSD bays and built-in virtualization. We will test how it works on it and get acquainted with the new branded SSD from Synology. In general, it's time to stop talking about Synology's top models as NAS-s for medium-sized businesses. A few years ago, the company set a course for unification and hyperconvergence, deciding that many customers will be able to transfer their local services to storage using virtualization ...
