Every component used in Perle Industrial Temperature Ethernet Switches have been designed and tested to handle operating temperatures between -40 and 75C.  Many Ethernet switch manufacturers claim -40 to 75C but use commercial parts which will severely limit the reliability and lifecycle of the product. Product failures become inevitable when “commercial-grade” parts are exposed to extremely high or low temperatures.  For example, integrated circuits on the PCB overheat causing premature failure of the product. Under-rated connectors do not allow for proper contact between the device and the cables. These failures eventually stop all data communications in these high and low temperature environments.

Managed Ethernet switches have more capability than unmanaged switches, but they also require a skilled administrator or engineer to make the most of them. A managed switch enables you to have better control of your network and all the data frames moving through it. Unmanaged switches, on the other hand, enable connected devices to communicate with one another in their most basic form.

Unmanaged switches do maintain a media access control (MAC) address table, however. This table keeps track of dynamically learned MAC addresses and the corresponding switch port on which the MAC address was learned. The inclusion of a MAC address table means unmanaged switches do offer a separate, per-port collision domain. This is a key differentiator between an unmanaged Ethernet switch and an Ethernet hub.

Managed Ethernet switches
A major difference between managed and unmanaged switches is control. A managed switch lets you adjust each port on the switch to any setting you desire, enabling you to monitor and configure your network in many ways. It also provides greater control over how data travels over the network and who has access to it. Managed switches generally offer Simple Network Management Protocol, which enables you to monitor the status of the switch and individual switch ports and gives you statistics like traffic throughput, network errors and port status.

Features available on managed switches may vary among manufacturers and models, but they often include the following:

Below, we compare the differences between managed and unmanaged switches.

Unmanaged Ethernet switches
Unmanaged switches use autonegotiated ports to determine parameters such as the data rate and whether to use half-duplex or full-duplex mode. Additionally, unmanaged switches have no concept of virtual LANs (VLANs). Thus, all devices belong to the same broadcast domain.

The very first thing you should do is make sure you’re on a delicious 5GHz signal. If you don’t know, there are two kinds of WiFi connection that you’ll generally find in your home, 2.4GHz, and 5GHz. 2.4GHz is better at penetrating walls and other solid surfaces, and was the tip-top standard for so many years it’s almost frightening. So why are we telling you to change that around if 2.4GHz is so lovely? Well, truth be told, almost all wireless devices use the same frequency, such as Joy-Con, Pro Controllers, wireless controllers for ‘other’ systems, your phone, anything with bluetooth, it’s all 2.4GHz, and that gets very messy very quickly.

We all know that the Nintendo Switch and the Switch Lite are fantastic little pieces of hardware. However, there is a smattering of small complaints about these devices. One such gripe I have heard about more than a few times is that neither Switch offers any sort of built-in web browser. The good news is that you actually can use a web browser on your Switch, and you don't have to do anything as warranty breaking as hacking your gaming system. If you want to surf the net on your Switch or Switch Lite, here's how to do it.
You manage a network with a single switch. On each switch port, a hub connects multiple devices to the switch.

It's important to note that, by accessing the web browser on a Nintendo Switch or Nintendo Switch Lite in this un-official way, you risk having your personal information tracked and stolen, as this is not a secure method of web browsing. Please don't use it without considering the risks.

what is a managed switch

Contributor(s): John Burke, Dominique Brazziel
A network switch is a hardware device that channels incoming data from multiple input ports to a specific output port that will take it toward its intended destination. It is a small device that transfers data packets between multiple network devices such as computers, routers, servers or other switches.

In a local area network (LAN) using Ethernet, a network switch determines where to send each incoming message frame by looking at the physical device address (also known as the Media Access Control address or MAC address). Switches maintain tables that match each MAC address to the port which the MAC address is received.

A network switch operates on the network layer, called layer 2 of the OSI model.

Network device layers
Network devices can be separated by the layer they operate on, defined by the OSI model. The OSI model conceptualizes networks separating protocols by layers. Control is typically passed from one layer to the next. Some layers include:
what is a managed switch

Layer 1- or the physical layer or below, which can transfer data but cannot manage the traffic coming through it. An example would be Ethernet hubs or cables.
Layer 2- or the data link layer, which uses hardware addresses to receive and forward data. A network switch is an example of what type of device is on layer 2.
Layer 3- or the network layer, which performs similar functions to a router and also supports multiple kinds of physical networks on different ports. Examples include routers or layer 3 switches.
Other layers include layer 4 (the transport layer), layer 5 (the session layer), layer 6 (the presentation layer) and layer 7 (the application layer).

How a network switch works

Fundamental concepts of a networking switch.
Switches, physical and virtual, comprise the vast majority of network devices in modern data networks. They provide the wired connections to desktop computers, wireless access points, industrial machinery and some internet of things (IoT) devices such as card entry systems. They interconnect the computers that host virtual machines (VMs) in data centers, as well as the dedicated physical servers, and much of the storage infrastructure. They carry vast amounts of traffic in telecommunications provider networks.

When it comes to technology in our daily lives there are many purchasing decisions that come before the buy. Which streaming service will provide the best shows for the lowest price and result in fewer “what do we watch tonight” discussions? Is that Instant Pot really going to make dinner easier to make? Should I splurge on the new Nintendo Switch? The same is true for network switches. It's important to understand the fundamentals of network switches.

While we can’t advise you on which streaming service to use (although season one of He-Man and the Masters of the Universe is now available on Netflix… by the power of GreySkull anyone?) or which kitchen gadget is the best, we can talk switches. We think the new Nintendo Switch is pretty sweet, but at CXtec our true expertise lies in networking switches and other networking technology. .

The Basics of Network Switches

Ethernet Switches
We’ll start broad first—after all, every super hero should understand the big picture of his or her mission. Ethernet switches, also known as LAN (local area network) switches, are an integral part of any computer network. They can be broadly categorized into two main categories: Modular and Fixed switches.

Modular Switches
If you’re looking for expansion capabilities, modular is where it’s at. Modular switches make it possible for you to add expansion modules as needed into the switches. These types of switches provide the best flexibility, but come with a price because they are more complex than their fixed switch cousins. While you may have more limited flexibility, if you’re looking for a lower entry cost, fixed switches may be a better place to start.

Fixed Switches
As their name implies, these switches typically aren’t expandable and they have a fixed number of ports. This category can be broken down even further into unmanaged, lightly managed, and fully managed. When it comes to network switches, the details matter.
The most common kind of switch, at least for homes and small businesses, is called an unmanaged switch. That means the switch itself has no settings or special features, and it exists only to add more Ethernet ports to your network. Your router continues to handle your Internet connection, letting your devices talk to one another and restricting what certain devices can do through parental controls or other settings—the switch is effectively invisible. In contrast, the kinds of things that managed switches do—such as monitoring traffic on individual ports or setting up virtual networks (VLANs) using the same switch—are really important only for large corporate networks.

type. Many switches today offer high-speed links, like Fast Ethernet, which can be used to link the switches together or to give added bandwidth to important servers that get a lot of traffic. A network composed of a number of switches linked together via these fast uplinks is called a “collapsed backbone” network.

Dedicating ports on switches to individual nodes is another way to speed access for critical computers. Servers and power users can take advantage of a full segment for one node, so some networks connect high traffic nodes to a dedicated switch port.

Full duplex is another method to increase bandwidth to dedicated workstations or servers. To use full duplex, both network interface cards used in the server or workstation and the switch must support full duplex operation. Full duplex doubles the potential bandwidth on that link.


A managed switch is a network switch that contains software and hardware to supercharge the way you run your network. Additional functionality like SNMP (Simple Network Management Protocol), VLANs (Virtual Local Area Network) and so on gives you more control and improve your network performance. This article gives you all the main points to understand the basics of managed switches and decide if it is worth investing in the managed switch for your network. Let’s dive into it.
We will be honest with you. Our opinion is that if your network is even slightly above basic, we strongly advise looking into managed switches. It will significantly improve the management and running of your network even for a home network. Although the best managed switches which we picked in our list will cost you double ($150 – $600) of the unmanaged switches, it is worth it.
Managed switches have a number of important features:

Ability to prioritise network connections (QoS) – so your IP calls or video will never be interrupted
Added security by ringfence some devices (VLAN), for example for testing purposes
Granular monitoring of network stats (enabling SNMP)
Advance networking tools like IP routing, CLI (Command-line Interface)
