Power over Ethernet (POE) is a technology that allows network cables to carry electrical power. POE allows Powered Devices (PDs), such as IP telephones, wireless LAN access points and network cameras to receive power, in addition to data.
A POE switch provides power supply and data connection to POE devices via a single network/Ethernet cable. The switch injects power to your network that is utilized by POE enabled devices on the network. This is one the most effective ways to use Power over Ethernet when you have more than a couple of POE enabled devices like security cameras or access points. The Best POE Switches will reduce the time and expense of having electrical power cabling installed.
There are different factors to consider while buying a POE switch. Factors include, power consumption of the POE device, maximum power supply of the POE switch, the power supply voltage of the switch and the port numbers on the switch.

- Type of POE switches
There are three types of POE switches; unmanaged, managed and smart PoE switch. The managed switches are the most used in actual applications.
An unmanaged switch is the most basic form of a network switch. This switch only allows your devices to connect to each other. It is best suited for home and small office uses. If you have a business that handles sensitive information such as an accounting firm or a bank, such a switch is not recommended for your workplace.
A managed POE switch offers security features and full management capabilities. It can be configured to give a more tailored experience. It can help you monitor and control the overall traffic of the network. Such switches are usually used in company networks and data centers.
A smart PoE switch or a hybrid PoE switch is a switch that has functions of a managed as well as an unmanaged switch. It allows you to configure ports and set up virtual networks. However, it doesn’t allow network monitoring, troubleshooting, or remote accessing. It is generally used in business applications such as VoIP and smaller networks.
- Port Numbers: Network switches have different port numbers such as an 8-port POE switch, 24-port POE switch, etc. The larger the network, the more the number of ports you’ll need. It is always advisable to pick a switch that has more interfaces than you actually need.
- Maximum Power Supply: The maximum power supply of your PoE switch also holds importance. If it is less than the overall power required from your powered devices then the PoE switch won’t provide enough power for all your PoE IP cameras. This leads to the insufficient power supply which may cause poor device performance including video buffering.
- Maximum Power Consumption: You can estimate the power consumption of all your powered devices (PDs) in advance to see if your POE switch can support all these devices. Normally, there are two types of PoE standards, namely IEEE802.3af and IEEE802.3at. The former supplies up to 12.95W of DC power on each PD while IEEE802.3at can provide up to 25.5W. PDs are only suitable for IEEE 802.3at PoE standard if their power consumption is between 12.95-25.5W.
1. What Is The Difference Between A Poe Switch And An Injector?
PoE switch is an all-in-one device with no additional appliances. The ports on the device can be used to manage both power and network. On the other hand, a PoE injector can be added to existing cabling with no need to change the switch. It adds power to an ethernet cable for the PoE equipment. It is also easy to mount it anywhere.
Another main difference between these is, if PoE switch breaks, all PoE powered devices will be switched off. However, if a PoE injector stops working, it will only affect one or two devices. This adds resilience to your network.
As the cost of POE injector is lower than that of the switch, the former is a good choice only if you have a few things to power.
2. What is PD detection in POE powered switches?
The first step for POE equipment is to ascertain whether a device connected to a port is a valid Powered Device (PD). PDs will require power as well as network communication through the attached LAN cable.
There are different types of energy-efficient ethernet standard [IEEE] that the POE switches are supposed to follow. The system detection protocol IEEE 802.3af-2003 involves applying a DC voltage between the transmit and receive wire pairs to calculate the current received.
A POE will demand roughly 25K Ohm resistance and 150nF capacitance between the pairs for the device to be considered a valid PD. The POE will check for the presence of PDs on connected ports at regular intervals, so power is removed when a PD is no longer connected.
3. How does a POE switch work?
PoE requires little configuration or management. The POE automatically identifies whether the device connected to a port is a PD or not; it can also determine the power class of the device. The POE can supply up to 15.4 watts of power to the device, while at the same time providing standard Ethernet network functionality.
It is easy to set up a PoE switch.
- Connect the router to the LAN port on the switch using Ethernet cables.
- Connect the power cable to the PoE switch and a surge protector to the power source.
- Connect IP cameras to any of the port on the PoE switch using Ethernet extension cables.
- Add the cameras to the Network Video Record of your computer for viewing the video feed and to begin recording.
If you want a POE switch that is affordable which is power-saving and has gigabit ports, we recommend you choose Netgear GS108pp. This is a great POE switch that comes in many different configurations for advanced users. It is also a smart switch so a beginner would have no problems in using this device. However, before purchasing this device calculate how much power you would require to operate the PoE devices you will be connecting to this.
There is a hike in the number of PoE devices becoming available in the market. The common uses for PoE are for supplying power and network for communication devices such as VoIP phones and wireless LAN access points. However, there are different devices that are now taking advantage of PoE technology namely, ethernet hubs, digital clocks, intercoms, and even a network electric guitar.
