Tag: PoE switch

The telecommunication industry has always been developing with leaps and bounds and technology changes with each passing day. For common people with few network knowledge, the evolving optional network devices like PoE switch can be a big puzzle. What is PoE? What is the distinction of gigabit PoE switch vs normal switch? Read this article for reference.

What Are PoE and PoE Switch?

PoE, abbreviation of Power over Ethernet, is a technology that enables Ethernet cable to supply power. Thus power sourcing equipment (PSE) can transmit both data and power to powered devices (PD) simultaneously via one single cable. PoE has two standards available on network switch: IEEE 802.3af/at. The former orginal PoE standard is defined in 2003, which provides 15.4 W power budget to PDs (12.95 W available for accessing). The latter PoE+/PoE Plus standard defined in 2009 provides up to 30 W (25.5 W) power.

PoE switch is one of the two types of PSE for PoE implement: endspan switch and midspan PoE injector. To enhance network resiliency, gigabit PoE switches provided by FS.COM are highly compatible IEEE 802.3af/at managed PoE+ switches. For example, S1130-8T2F managed gigabit 8 port PoE switch with 2 SFP ports can connect to gigabit Ethernet network while S1600-48T4S 48 port PoE switch can use the SFP+ ports to connect with 10gbe switch for higher performance data transfer.

PoE Switch vs Normal Switch: What’s the Difference?

In a word, PoE switch and normal switch differ from PoE accessibility. A regular Ethernet switch is not PoE enabled to supply power for end users over Ethernet. Therefore the user requires one extra cable to connect power outlets. However a normal switch can also become PoE ready by employing a midspan injector between the switch and PDs. The injector will add electrical power while receiving data signal from Ethernet switch end cable, and then deliver both data and power to PDs. But in this circumstance the injector also needs a wire for power. When using gigabit PoE switch, only one power cable is required. Then the PDs can be directly plugged into the PoE gigabit switch port for both data transmission and power supply. The illustration and table below list the differences of employing PoE switch vs normal switch while adding PoE to network.

What Are the Advantages of PoE Switch?

As mentioned above, PoE switch differs from normal switch for supplying power to PDs in the meantime of data delivery. Though the normal switch system can also acquire PoE by installing injector, PoE endspan has the superiority of direct Power over Ethernet ability. Counting to this, gigabit PoE switch owns edges over normal switch as follows. First, it enables PDs like IP surveillance cameras to be placed almost anywhere: on the ceiling, concealed in a wall, or even underwater while only one cable is needed to run to them. Second, it saves extra expanse and time for power cabling and injector installation. Third, with simplified cabling of all PDs directly connected to gigabit PoE switch, the data center is easy for management and control. Besides, PoE gigabit switch itself is designed with advanced features like high-performance hardware with software, auto-sensing PoE compatibility, strong network security and environmental adaptability.

Conclusion

Gigabit PoE switch can supply power to PDs in the meantime of data transmission via one single Ethernet cable while normal switch can only send data to them. For PoE implement, normal switch requires a power-on auxiliary injector as midspan between switch and powered devices. Thus PoE switch owns advantages of direct PoE connection, easy and flexible placement, cost-efficiency, simplified management and etc. For any applications of IP surveillance cameras, VoIP phones and wireless APs, PoE switch over normal switch is a good solution to go.

Power-over-Ethernet (PoE) is the technology that allows network switches to transmit power and data through an Ethernet cable at the same time. PoE switch streamlines both of the processes of powering and providing data to the device, which makes it a straightforward and reliable device for home network and small enterprise application. This article describes two types of PoE (PoE and PoE+) that are commonly used and provides information on what types of PoE can be used according to different applications.

PoE Versus non-PoE Technology

Power over Ethernet technology facilitates powering a device (such as an IP phone, IP Surveillance Camera, or NVR recorder) over the same Ethernet cable as the data traffic. Figure 1 shows an Ethernet Network with IP camera, PoE Switch, NVR recorder and Wireless router. Compared to non-PoE devices, PoE devices feature with flexibility that allow you to easily place endpoints anywhere in the business, even places where it might be difficult to run a power outlet.

PoE Versus PoE+ Technology

PoE was first defined in the IEEE 802.3af standard. PoE devices utilize PoE standard, which can provide up to 15.4W of DC power to each port. A later standard, IEEE 802.3at, known as PoE+, increases the amount of power to 30 W. The major difference between 802.3af (PoE) and 802.3at (PoE+) is that PoE+ PSEs can provide almost twice as much power over a single Ethernet cable.

Can PoE+ devices work over PoE Ports, Or vice versa? The PoE+ standard provides support for legacy PoE devices, meaning that an IEEE 802.3af powered device (PD) can operate normally when connected to IEEE 802.3at (PoE+) power sourcing equipment (PSE). PoE+ PSEs can supply power to both PoE and PoE+ PDs. However, as PoE+ PDs require more power than PoE PSEs can provide, PoE PSEs can only supply power to PoE PDs.

PoE Switch Or PoE+ Switch

Whether to use PoE or PoE+ switch for your network, you need to calculate your required power budget carefully for all of the PDs you plan to connect. PoE+ IEEE 802.3at devices can supply a maximum of 30 watts per port, while PoE IEEE 802.3af devices can supply a maximum of 15.4 watts per port. However, some power is always lost over the length of the cable, and more power is lost over longer cable runs. The minimum guaranteed power available at the PD is 12.95 watts per port for PoE and 25.5 watts per port for PoE+.

For most endpoints, 802.3af is sufficient but there are devices, such as Video phones or Access Points with multiple radios, which have higher power needs. It’s important to point out that there are other PoE standards currently being developed that will deliver even high levels of power for future applications. Optical switches have a power budget set aside for running the switch itself, and also an amount of power dedicated for PoE endpoints.

fiber-mart PoE Switches

fiber-mart POE switches can supply power to network equipment such as weather-proof IP cameras, AP and IP telephones. They are featured with high flexibility, high stability and high resistance to electromagnetic interference. All fiber-mart PoE switches come with a one-year limited warranty, including any quality problems during the free maintenance. The following above shows 1G PoE Switch with 24 1000BASE-T and 4 SFP ports.

PoE switch performance is more advanced and sophisticated, the appearance is more and more handsome. With the development of network monitoring, PoE switch applications are more and more common, so a lot of information about PoE switch can be found on the Internet.

So, there are a lot of articles on the PoE switches and network monitoring, and some people say PoE switches to promote the development of network monitoring, and some others say that network monitoring to promote the development of PoE switches, then in the end who promoted who?

Referred to the surveillance camera, is really all over the city streets in various places, as long as you live in the city, everywhere you can see his shadow. Although sometimes very annoying, but have to say that a variety of monitoring measures do put an end to a lot of violations of the crime, but also can provide a basis for the incident.

With the planning of “Safe China”, “Intelligent City” and other projects, as well as the increased safety awareness of people, the scale of video surveillance installation and the radiation area are getting bigger and larger, the project scope of which involves the whole city, the camera reaches tens of thousands. However, not every place is suitable for the installation of network cameras, that is to say, the installation of network video surveillance equipment is constrained by the environment, which to some extent restricts its development.

We know that all devices need the power to work, and surveillance cameras are no exception. In the traditional monitoring system, usually using mains power or centralized power supply, and in network monitoring, these modes of power supply sometimes can not meet the needs. Because it is network monitoring, of course, a need of network cable, if you want to supply additional cable, especially in some inconvenient power supply environment, the construction becomes extremely complex and troublesome, at this time, have to redeploy the camera installation location, this also lost the significance of monitoring.

How to solve this difficulty? Thus, the technology of PoE, which can be powered by Ethernet, has received wide attention and attention. Through the technology of PoE Power supply, the power signal can be added to the network cable, which is transmitted to the other end of the equipment which needs to be powered. This can be an excellent solution to network monitoring power supply problems, as long as the power and data through a cable can be completed transmission, not only solve the power supply problems, and make the project easy to do, as long as the network cable to the place, you can make equipment to obtain a steady supply of electricity.

In order to make PoE better applicated in the security network monitoring, PoE switches can be quickly promoted. Commonly used PoE power supply equipment includes PoE module and PoE switches, that is the most common used.

PoE switch is also a kind of switch, the biggest difference between ordinary switches is that it can be a power supply, not only has the ability to transfer data. In other words, the PoE switch can not only transmit data can also power supply, which is also appropriate for the network monitoring needs, because the surveillance cameras need both power supply, there is a need to collect the monitoring data sent out. With the PoE switch, the surveillance camera can be installed at any optimal point without the need for environmental and power access restrictions. PoE switch is also favored by many system integrators because of its high performance, simple use, easy management, convenient networking and low construction cost.

The PoE switch that we often refer to is the standard PoE switch, which supports IEEE802.3AF/T power supply standards, but there are also non-standard PoE switches on the market. Non-standard PoE switch Although the price is relatively cheap, but because of the existence of the hidden dangers of the front-end cameras, we recommend that you choose carefully.

Conclusion

What is the relationship between network monitoring and PoE switch? Our view is that they are two different concepts, but can promote each other, but it is necessary to note that network monitoring is not a PoE switch can still be done, and the PoE switch is not network monitoring, its application will be greatly compromised. It can be understood that the PoE switch is a transmission power supply device for network monitoring.PoE switch performance is more advanced and sophisticated, the appearance is more and more handsome.

Network has become an essential part of our daily life. To make life easier, there are various types of network devices on the market, such as such as IP phone, wireless access point and IP camera. Each of them not only has to get access to the network through the Ethernet cable, but also needs power supply via power cord. When the number of devices is a little more, the cabling will be complicated. How to solve this problem? Recently, PoE (Power over Ethernet) technology is popular, which can transmit both power and data through an Ethernet cable at the same time. When it comes to PoE, there are two hot devices: PoE switch and PoE injector. And people often ask: PoE switch vs. PoE injector: which one to choose? This article will make a comparison between them and help you make the choice.

PoE Switch vs. PoE Injector: What is PoE Switch?

PoE switch is a network switch that has Power over Ethernet injection built-in. When connected with other network devices, PoE switch will detect whether they are PoE-compatible and enable power automatically. Therefore, it is a simple solution to add PoE to your network by using PoE switch. In addition, there is PoE+ switch available on the market. PoE switch utilizes the original PoE standard, IEEE 802.3af, which provides up to 15.4W of DC power to each device. While PoE+ switch use the latest PoE+ standard, IEEE 802.3at, also known as PoE class 4, which provides up to 30W of power to each device. That’s to say PoE+ switch can provide almost twice as much power as PoE switch. The following figure shows a 8-port PoE switch which is popular among many users.

PoE Switch vs. PoE Injector: What is PoE Injector?

PoE injector is used to add PoE capability to regular non-PoE network links. The following figure shows the application of PoE injector. Both PoE injector and non-PoE Ethernet switch are powered on. Then they are connected by an Ethernet cable. By doing this, the PoE-compatible IP phone, wireless access point and IP camera can work through one Ethernet cable respectively connected to PoE injector. In network deployment, PoE injector can provide a versatile solution when fewer PoE ports are required.

PoE Switch vs. PoE Injector: Which One to Choose?

PoE switch is all-in-one box with no additional appliance and the ports on it can be used to manage both network and power. While PoE injector can be added onto existing networks with no need to change the switch and is easy to mount anywhere. As for which one to choose, it really depends on the specific requirement. For example:

If you only have a few things to power, then PoE injectors are good. The cost is lower when compared to a PoE switch.

If the PoE goes out in a PoE switch, all PoE has the chance of going out. But if a PoE injector goes out, it only affects one device.

If you do have to replace a PoE injector, you can just replace the bad injector without any production downtime anywhere else in the network.

Conclusion

Both PoE switch and PoE injector utilize PoE technology which makes network deployment even simpler and have their own advantages. It is important to figure out what you need before you make a choice between them. What’s more, please ensure your device supports PoE before connecting into a PoE-enabled network. PoE Switch Vs. PoE Injector, hope this article is helpful for you.
