What is a PoE Switch?
A PoE Switch is a device that combines the functions of a switch and a power source in one product. A PoE switch has multiple Ethernet ports that are used to connect other devices such as VoIP phones, wireless access points or IP cameras. The main task of this type of switch is to provide power to connected devices, instead of users having to use separate power cables. Therefore, they are often the preferred choice of administrators when deploying networks in locations with few power outlets or having to place devices in hard-to-reach places.

The technology used to create PoE switches is called Power Over Ethernet (PoE). This is a method that allows both data and power to be transmitted over Ethernet cables. It combines a power source and a power supply to deliver power to connected devices. In this case, the power supply acts as a bridge between the power source and the connected devices in the network system. At the same time, they are responsible for transmitting both data and power.
PoE Switches are compatible with many other devices, making installation and use simple and convenient for users. PoE switches were created to help simplify the process of installing enterprise network systems, optimizing PoE power allocation and setup costs.
Popular types of PoE Switches today
To choose a PoE Switch, it is important that you understand the types of PoE switches available. Below, DNG Corp has summarized for you the popular types of PoE Switches today:
Classification by number of ports
Power over Ethernet switches provide users with 4 to 48 connection ports. In which, the most used product lines are 4, 8, 12, 24 and 48 output ports, also known as PSE ports.
Classification by features
PoE switches classified by product features will have two main types: Unmanaged and Managed PoE switches.
Unmanaged PoE switches: are simple Ethernet switches, suitable for use in households, offices or small businesses. This type of device is user-friendly, not complicated in configuration, all you need to do is plug and play.
However, because they only have basic functions, they do not provide customization, management and security options for users.

Chuyển mạch PoE được quản lý: Thiết bị cung cấp các tính năng nâng cao, vượt trội trong các trường hợp yêu cầu quản lý mạng chính xác. Với khả năng kiểm soát tăng cường và bảo mật mạnh mẽ. Đây là lựa chọn lý tưởng cho các mạng doanh nghiệp, trung tâm dữ liệu hay hệ thống giám sát quy mô lớn, đòi hỏi các tính năng phức tạp như VLAN, QoS, phản chiếu cổng và bảo mật cổng nâng cao.
Speed PoE Switch
Each PoE switch line can provide connection ports with different transmission speeds. According to each speed level, PoE switches are classified into the following types:
- Ethernet port: Provides 10Mbps speed.
- Fast Ethernet (FE) port: Transmits at 100Mbps speed.
- Gigabit Ethernet (GbE) port: High-speed transmission, up to 1000Mbps (or 1Gbps).
PoE Switch using 10/100/1000 Mbps GbE connection port is the most popular line chosen by users today.
Power Consumption
To choose a Power Over Ether switch, you need to consider the power consumption of the devices to make the right decision.
The standard power consumption of PoE is as follows:
Main features of PoE Switch
PoE Switch devices have the following outstanding features:
- Flexible use: The product helps administrators deploy easily and conveniently for any necessary network device. If using a conventional switch, users need to add PoE output ports and extension cables. With PoE Switch, it eliminates the need for additional cabling, allowing the device to be installed in any desired location. At the same time, users can use the network remotely without having to install a complex network wiring system, which is unsightly.
- High reliability: Using PoE technology, these switches are capable of connecting all devices together, avoiding dispersion on power sources. Accordingly, the transmitted data is also guaranteed to be secure, avoiding information theft. In particular, users can secure data by assigning IP addresses. From there, you will be able to determine whether this login address belongs to your network system. Compatible with many types of devices: PoE Switch is designed to operate similar to a power supply device. After receiving power from each IP Camera, all devices will also be powered to operate. In addition, they also have the ability to compare information about the total number of each connected camera device. Increase transmission speed: PoE Switch helps increase transmission speed, limit interruptions during transmission. Thereby, improving the user’s high-speed network experience.
- Optimize setup costs: When using PoE Switch, users do not need to buy or install additional wires and sockets. Therefore, you can save significantly on investment and maintenance costs as well as construction time.
- Ensure the transmission line is at the required level: Make settings so that the power going through the Power Over Ethernet Switch is at the rated capacity for each type of device. The total power consumption of these devices also needs to be controlled within the maximum power consumption range of the PoE Switch. Thereby, helping to avoid cases of power waste.
- Easy configuration and installation: Users can easily configure and deploy the network system via PoE switches on an intuitive, easy-to-see web interface.
Applications of PoE Switch
Power over Ethernet (Power Over Ethernet) switching is becoming increasingly important and necessary for most network infrastructures. The following are the most common applications of PoE Switch:
- VoIP Phones: VoIP Phones are devices that integrate PoE technology that allow a single connection to a wall outlet. In addition, users can remotely turn off the power.
- IP Cameras: Most IP camera systems today are powered via Ethernet ports, making image transmission simpler, clearer and more efficient.
- Wireless Access Points: Many wireless access points are designed to be compatible with PoE. At that time, PoE Switches allow devices to be easily moved and located remotely.
- Smarthome Automation: PoE Switches are used in LED lighting systems, heating and cooling systems, voice devices and electric vehicle charging stations.
Some notes before using PoE Switch
Some factors that users need to note before choosing to use a power-over-Ethernet switch.
Consider the cost of buying a PoE Switch
Normally, PoE Switches will be more expensive than conventional switches. Because they use many outstanding features to support users’ work more conveniently and flexibly.
The cost of the product will depend on each type. In the case of the same type of product, the price will depend on the number of connection ports. If the product has a higher speed connection port, the price will be more expensive.
Disadvantages of PoE Switch
In addition, they also have some limitations that need to be noted:
Limited distance: PoE switches are capable of transmitting data over Ethernet at a distance of up to 100m. Because there is a distance limit of 100m, it is also a limitation when used for large facilities. However, users can expand the range of PoE Switch by adding an extension power supply and power fiber optic cable. Power source: For PoE to operate at high power, users must ensure that PoE switches meet the power requirements. Above is all the information about what a PoE Switch is and its applications in life.
