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 ...

One of the ways to protect a web service may be to restrict access to it by IP, including GeoIP, based on the user's location. We will set up protection without using paid services, without Maxmind, without registration and SMS Today, many organizations that transfer their services to web platforms are forced to provide an entry point to the Internet for user authentication. Even with 2-factor authentication, a web service accessible via the Internet remains vulnerable to complex attacks, the ...

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 modern NAS is quite capable of protecting itself from most attacks and guaranteeing not only the continuity of the service, but also the inviolability of the stored data. Even with minimal settings and following the manufacturer's recommendations, the NAS can become an impregnable fortress for an attacker, so reliable that you can connect the device directly to the Internet without a Firewall, leave it literally in an unguarded place (which is important for peripheral installations), being ...
