Types of Gigabit Network Switch

Gigabit Ethernet switch can be divided into unmanaged, managed and PoE categories.

Unmanaged switches use the plug-and-play design that means they only allow Ethernet devices to communicate with one another. They are shipped with fixed configuration and don’t allow any changes to this configuration. This type of network switch is normally found in home networks or small business.

Managed switches offer all the features of unmanaged switches and are capable of configuring, managing and monitoring one’s LAN. Users have greater control over how data travels over the network and decide which one has access to it.

PoE switches support electrical power and data transmission over one network cable, which will greatly simplify the cabling process. Using a PoE switch, people don’t need to worry about power outlet when deploying network devices.

Features of Gigabit Network Switch

With a network switch, users can have different networked devices on their desks as well as bandwidth-intensive applications that require high rates of data transmission and no tolerance for congestion. These switches are the basics of modern wired network. They can not only provide the connections to PCs and other devices in a wide variety of fields, but also support the cloud storage of servers. With new trends like SDN and the IoT transforming the industry, people have to get the features that they need from the switches, so that they would know which switch is the one that they need.

How to Choose a Gigabit Network Switch?

Here are the most important facts you should consider when choosing a Gigabit network switch.

  • Choose the role of the switch. If you are just looking for a device to extend your wired network at home, one unmanaged switch is suitable. And an 8 port Ethernet switch or 12 port switch is enough for home network. If you want to find a switch for a large network, you may buy one or more managed switches acting as core switches. 24 port and 48 port PoE managed switches are the right choice.
  • Choose the forwarding rate of the switch. Gigabit switches have different processing rate. Processing and forwarding data rates are very important. The processing rate becomes lower, the forwarding rate will be slower. This may make the switch unable to accommodate full wire-speed communication across all the ports. So people should figure out what forwarding rate they need before buying a Gigabit switch.

Conclusion

From the above, we know how to choose a Gigabit network switch. If you have decided to buy a network switch, welcome to visit FS.COM. FS has a good selection of 10Gb switch, 40G or even 100G switch and PoE switch for home and office users.

What Is a KVM Switch and How Does It Work?

Today, data centers and companies have to deal with the space limitation of lots of computers. They need a method to control the increasing numbers of computers and other networking devices efficiently. KVM switches are invented to combat this issue that is taking up valuable space and time. So what is a KVM switch and how does it work?

what is a KVM switch

Figure: KVM switch is widely used in our life.

What Is a KVM Switch?

What is KVM? KVM stands for keyboard, video and mouse. And as for what is a KVM switch, it’s technically “keyboard, video and mouse switch”. KVM switch is a hardware device that allows users to control different computers through one set of keyboard, video monitor and mouse. This is the KVM over IP solution, which is very useful if the server settings are located off-site and you don’t want to drive over there each time when you need to make changes. The switches will be assigned an IP address and accessed from any place in the world with the right username and password.

In addition, we should note that, although KVM switch and Gigabit Ethernet switch both can control multiple computers or servers, they are different devices. KVM switch is usually considered as a hardware device, which is popular when people have upgraded their computer systems or add new computers but don’t want to invest in a second keyboard, display and mouse. While Ethernet switch is regarded as a central hub. Commonly, it’s connected to each computer or network device in an Ethernet. Therefore, they are two different devices with different functions.

How Does KVM Switch Work?

We have a good understanding of the question what is a KVM switch. It can control more than two or greater numbers of computers(over 500). Users can use Cat5 cables or the specific KVM cable kits to connect the computers to the KVM switch. Then, connect the keyboard, display and mouse console to the KVM switch. If the switch is equipped with the console, this step could be skipped. Now users can use a button, on-screen display controls or hot keys on the keyboard to switch from one computer to another.

Which Type of KVM Switch Do I Need?

Designed for various end-user needs, there is a considerable choice of KVM switches on the market. Before buying, you should consider:

  • How many computers do I need to control?
  • What type of KVM switch do I require?
  • Do I need an on-screen display?

DSL vs Ethernet Cable vs Fiber Optic Cable Speed

Wifi is excellent, we all love it. But under the wireless work, there are serious cabling, and data travels through DSL, Ethernet cables and fiber optic cables. The question is, which one performs better? And what’s the difference between DSL, Ethernet cable and fiber optic cable speed? Don’t worry, we are here to help you understand the key differences among the different cables.

DSL vs Ethernet Cable vs Fiber Optic Cable Speed

What Is DSL?

DSL stands for Digital Subscriber Line. It’s a communication medium used to deliver digital signals via the copper telephone lines. DSL service functions much like dial-up Internet service. However, unlike dial-up service, the “two-wire” technology of DSL makes it possible for users to connect to the broadband internet and make or receive phone calls at the same time. Because DSL utilizes the existing telephone lines which means there is no requirement for extra cabling for DSL service. Thus, it allows users to download files, watch online videos and support cloud backups.

What Is Ethernet Cable?

Ethernet cable is the most common network cable type in our daily life, which is specifically designed to facilitate the communication between different electronic equipment such as computers, fax machines or scanners. Cat3, Cat5, Cat5e, Cat6, Cat7 are the different Ethernet cable types. Each new promotion of category supports increasingly faster bandwidth speeds and improves upon the signal-to-noise ratio.

What Is Fiber Optic Cable?

The fiber optic cable contains strands of glass fibers inside an insulated casing. Compared with the wired cables, fiber optic cable speed is faster which is designed for long distance and high performance data networking. Single mode fiber and multimode fiber are the primary types of fiber optic cable. Both of them can support the world’s Internet, cable television and telephone system.

DSL vs Ethernet Cable vs Fiber Optic Cable Speed

When we buy the cables, the speed is always an important consideration. Now we’ll compare DSL, Ethernet cable and fiber optic cable speed.

  • DSL speed

Download speed of DSL is generally in the 1-35Mbps range, while the upload speed ranges from 1Mbps to 10Mbps. When the DSL packages speed is around 1 megabit per second, it’s suitable for basic web browsing and sending or receiving emails. If the cable speed is up to 6Mbps or 7Mbps, you can enjoy online music and standard video streaming but may be a little slow for HD video.

  • Ethernet Speed

Ethernet cable download speed usually starts from 10Mbps to 500Mbps, and the upload speed is 5-50Mbps. Note that these ranges are the criteria you can achieve for home use. And for the specific areas, internet providers offer much higher speed which can be 1000Mbps. With a faster data speed, you can enjoy HD audio streaming and VoIP services.

  • Fiber Optic Cable Speed

Fiber optic cable speed is the fastest. Download speed of a fiber patch cord could be anywhere from 250Mbps to 1000Mbps. And fiber providers commonly provide “symmetrical” service, which means the upload speed is as high as the download speed. Though fiber optic cable price is usually a bit higher than DSL or Ethernet cable, it’s always worth buying it. You are free to enjoy heavy web browsing, file sharing and online backup, superior download and upload. And it’s a great option for hosting servers and complex cloud-based services.

Conclusion

As described above, fiber optic cable speed definitely wins. If you want a connection that can move at lightning speeds, fiber is the best choice. If you care more about the budget, both DSL and Ethernet cable can offer plans that allow you to get a decent network speed at a reasonable price. DSL is the cheapest for lower speed plans, while Ethernet cable is the cheapest for higher speeds. So choose the best Internet cable service based on your needs.

How to Mount a Network Switch to a Rack?

A network switch has been recognized as one of the most important devices for today’s networking technology. It allows simultaneous transmission of multiple packets and partition a network more efficiently than bridges or routers. The rack mount switch can be installed in a standard 19-inch equipment rack or on a desktop or shelf. So how do you mount a network switch to a rack to establish network wiring connections? Here’s a step-by-step guide to teach you how to mount a network switch to a rack.

Preparations Before Mounting the Network Switch

Before rack mounting the switch, please pay attention to the following factors:

  • Location: The site should be at the center of all the devices you want to link and near a power outlet, so that it is accessible for installing, cabling and maintaining the devices in the rack.
  • Temperature: Since the temperature within a rack assembly may be higher than the ambient room temperature, check that the rack-environment temperature is within the specified operating temperature range (0 to 40 °C).
  • Mechanical Loading: Do not place any equipment on top of a rack-mounted unit.
  • Circuit Overloading: Be sure that the supply circuit to the rack assembly is not overloaded.
  • Grounding: The switch rack should be properly grounded.

How to Mount a Network Switch to a Rack?

Step1. Attaching the Brackets to the Switch

Attach the brackets to the network switch using the screws provided in the mounting accessory.

Step3. Adding Other Switches into the Rack

If there is only one data switch to be installed in the rack, then you can make the connection to a power source now. If there are multiple switches to be mounted, you need to install the another switch on the top of the first one in the rack, and then attach the power cords.

Step4. Attaching the Power Cords

After you complete mounting all of the switches in the rack, it’s time to connect the switch rack to the power source. Remember to verify that you have the correct power supply (AC-input or DC-input and the correct wattage) for your configuration.

Caution: To prevent bodily injury when mounting or servicing the switches in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

  • This network switch should be mounted at the bottom of the rack if it is the only unit in the rack.
  • When mounting the switch in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.
  • If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the switches in the rack.

Establishing Network Wiring Connections

After mounting your network switches to a rack, you can establish the network wiring connections according to your requirements now. If you’re using a Gigabit Ethernet switch, it can be connected to 10, 100 or 1000Mbps network interface cards in PCs and servers, as well as to other switches and hubs. It may also be connected to remote devices using optional SFP transceivers. No matter which type of network switches you are using, make sure that they are securely mounted in the rack and connected to the corresponding networking wiring systems.
