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 ...

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 ...

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 ...

Well, the time has come for more or less affordable switches for 2.5 Gigabit networks with copper cable and 10G on optics. In this model, even 1-gigabit ports are forwarded to a common matrix, which is why even on small packets high speed is maintained. And you know that 10 Gigabit Ethernet was introduced back in 2006, and was created mainly for file servers of small companies, and after a decade and a half, it still remains a novelty for many consumers in the small business environment. The ...

The XGS4600 Series Gigabit Stackable Layer 3 Switches are designed for use as root devices in small hotel, office and business center networks. They have 10 Gigabit SFP + slots for server farms and come with a lifetime warranty. Core switches perform the main function of distributing network traffic at a facility between WAN and network segments, such as Wi-Fi, video surveillance, workplaces, IPTV, and so on. Since they are the most critical network node, the design of such devices is ...

When testing this switch, we first of all check compatibility with cables and network adapters, evaluate the quality of the element base, speed and impact on latency between ports. When moving to a 10-gigabit network infrastructure, you are likely to come across two media: optical and copper. In the first case, these will most likely be backbone connections, and in the second, modern equipment, which usually has the 10Gbase-T standard. For these use cases, Zyxel has the XS1920, a 12-port ...
