Understanding Two Technologies: Switch Stack vs Switch Cluster

图片
With an increasing scale of network and the development of application technology, we intend to seek for a way to make full use of multiple switches with effective management. In general, there are mainly three technologies that we will use when we interconnect or combine several Ethernet switches together. The three technologies are switch cascade, switch stack and switch cluster. Sometimes it is difficult for people to differentiate between these three technologies in the first instance. In this article we will put emphasis on two technologies: switch stack vs switch cluster and put forward their connections and distinctions so as to provide you a comprehensive understanding. Figure1: switch cascade vs switch stack vs switch cluster Overview of Switch Stack vs Switch Cluster The comparison between switch stack vs switch cluster should be based on the sufficient understanding of their concepts. What Is Switch Stack Switch stack is a kind of technology that unites mult

FS 8 Port PoE Switch S1130-8T2F Connection

图片
PoE, also known as Power over Ethernet, renders network cables to provide both data transmission and power supply for PoE-enabled devices, which knocks out a mass of power cords during the network development. PoE also offers more flexibility for networking and simplifies the installation of devices like IP camera and wireless access point. To build a network with PoE technology, PoE switch is an essential part of this process. Nowadays, an 8 port PoE switch is popular with many users. In this article we mainly introduce FS 8 port PoE switch S1130-8T2F and relevant connection with IP camera. Overview of FS 8 Port PoE Switch S1130-8T2F FS S1130-8T2F 8 port PoE+ managed switch comes with 8 10/100/1000Base-T RJ45 Ethernet ports, 1 console port and 2 Gigabit SFP ports. It is compliant with IEEE 802.3af/at which can supply a maximum amount of power to 30 watts. With fanless design, this 8 port PoE switch features superior performance in silent operation and stability. Furthermore, FS

How to Choose the Right PoE Cabling

图片
Power over Ethernet (PoE) is a technology that enables electrical current to be transmitted over standard Ethernet network cables rather than traditional power cords. By operating power and data transmission over a single Ethernet cable, PoE has achieved popularization in a variety of applications, such as IP cameras, IP phones and Wireless Access Points. However, if there is no right PoE cabling, PoE can encounter cable heating and connectivity issues which will adversely affect the transmission performance from PoE switch to these devices and in reverse. So in this article, we will discuss some considerable factors and FS product recommendations related with PoE cabling. Figure1: PoE technology applications---PoE switch connecting to IP phones, APs and IP cameras by Ethernet cable Importance of the Right PoE Cabling Heat generation in cable bundles is one of the biggest issues that affect PoE performance. When power is added to balanced twisted-pair cabling, the copper con

PoE Switch vs PoE+ Switch: How to Choose?

图片
Power over Ethernet, or PoE, is a time-saving and money-saving technology that distributes power and data safely over an Ethernet cable to a targeted network or device. In the current market, if you take notice of switch types, you will find that there are PoE switch and also PoE+ switch. But what are their distinctions? How much do you know about them? In this article we have rounded up some knowledge to help you better understand PoE switch , PoE+ switch and their respective benefits according to different applications. PoE vs PoE+ Technology PoE was firstly defined in IEEE802.3af standard and upgraded to IEEE802.3at which is known as PoE+. PoE switches utilize PoE standard that can supply a maximum of 15.4 watts of DC power per port. While IEEE802.3at increases the maximum amount of power to 30 watts. However, some power will be lost over the length of cable. The minimum guaranteed power available at the PD (powered device) is 12.95 watts per port for PoE and 25.5 watts per por

Understanding Combo SFP Port on Ethernet Switch

图片
For new comers who are not familiar with the structure and functionality of Ethernet switch , they are apt to get confused with different ports built in for different connection. Except for those common ports on SFP switch, such as SFP port , there is another port called “combo SFP port”. Do you know what is it and what is the difference between SFP port and combo SFP port? In this article we aim to give you comprehensive understanding of combo SFP port on Ethernet switch. What Is Combo SFP Port on Ethernet Switch? In a nutshell, a combo SFP port is regarded as a single interface with dual front ends, i.e. an RJ-45 connector and an SFP (Small Form Pluggable) module (also called Mini-GBIC) connector. In other words, this is a compound port which can share the same switch fabric, port number and allow the users to configure their SFP switch according to different applications. But the two different physical ports can not be used simultaneously. It means that you can either plug a ca

PoE Switch for IP Cameras

图片
With further enhancement of safety consciousness from general public, IP cameras are widely used in areas like schools, enterprises, public areas and even families. Using a PoE switch for IP security cameras to ensure the safety of people and business is a common and popular behavior nowadays. In this article we will intend to explore the advantages of using a PoE switch and help you choose a proper PoE switch for IP cameras as well. Figure1: PoE switch application Benefits of PoE Switch for IP Cameras When talking about PoE technology, some users may think that it is dispensable to buy a PoE switch with a relatively high price since a PoE injector can also achieve power supply and even space saving for IP cameras. But the reality is that if you have many PoE-enabled devices like 10 IP cameras, it is the optimal choice to use a PoE switch . In addition, it also provide the following benefits for IP cameras: Easy Management and Low Cost A PoE managed switch allows the p
