With the continuous development of network technology, POE (Power over Ethernet) network switches have been widely used in modern network engineering.
This switch provides power to remote devices through network cables, allowing network and power to be transmitted simultaneously on the same network cable, greatly simplifying the wiring and installation process of network equipment.
However, when selecting and using POE network switches, we need to pay attention to some key issues, the most important of which is the power selection and calculation method of the switch.
1. Power of POE network switch
The power of a POE network switch mainly depends on the power it can provide, which is usually expressed in watts (W).
Generally speaking, the lower the power of a switch, the less power it can provide, and vice versa.
When selecting a POE network switch, we need to determine the power of the switch based on actual needs.
For example, if you need to provide power for some low-power-consuming devices, you can choose a lower-power switch; conversely, if you need to provide power for some high-power-consuming devices, you need to choose a higher-power switch.
2. Calculation method of POE network switch
When selecting and using a POE network switch, an important issue we need to consider is how to calculate the required power.
This usually involves two factors: one is the power consumption of the device, and the other is the power of the switch.
Device power consumption
The power consumption of a device is an important factor in determining the power required.
Generally speaking, the higher the power consumption of a device, the more power it requires.
Therefore, when selecting a POE network switch, we need to understand the power consumption of the device.
If the power consumption of the device exceeds the power of the switch, you need to choose a higher-power switch or use other power supply methods.
Switch power
The power of the switch is another factor to consider. When choosing a POE network switch, we need to understand the power it can provide.
If the power consumption of the device is high and the power of the switch is low, it may cause insufficient power supply or the device may not work properly.
Therefore, when selecting a POE network switch, we need to determine the power of the switch based on the power consumption of the device.
3. How to choose the appropriate POE network switch
Understand the power consumption of your device
When choosing a POE network switch, we need to understand the power consumption of the device.
This can be obtained by checking the device’s manual or consulting the manufacturer. At the same time, we also need to know the output voltage and current of the device’s power adapter.
Choose the appropriate power according to actual needs
After understanding the power consumption of the device, we need to choose the appropriate power based on actual needs.
If the power consumption of the device is low, you can choose a switch with lower power; if the power consumption of the device is high, you need to choose a switch with higher power.
At the same time, we also need to consider the number of devices and power consumption that may increase in the future in order to choose the appropriate power.
Choose a reliable POE network switch brand and model
When choosing a POE network switch, we need to choose a reliable POE network switch brand and model. This can be understood by looking at the product’s instructions, quality certification, user reviews and other information.
At the same time, we also need to pay attention to factors such as product after-sales service and warranty period.
In short, the power selection and calculation method of POE network switches is one of the important issues we need to consider in modern network engineering construction. Only by selecting appropriate power and reliable models can the stability and reliability of the network project be ensured.
