Here is a summary of 10 questions about POE power supply. These problems may exist when understanding POC. This article first discuss the top 5 questions of the 12 questions you must know about POE power supply.

Some issues you must know about POE power supplyⅠ

Question one: What exactly is Power over Ethernet technology and what is its definition?
PoE (Power Over Ethernet) refers to the situation where the existing Ethernet cabling infrastructure does not make any changes. While transmitting data for some IP-based terminals, it can also provide DC power supply technology for such equipment.
PoE technology can be used in addition to ensuring the normal operation of existing networks. This technology also secures existing structured cabling. It minimizes costs.

Question two: How should we choose Power Over Ethernet switches?
When choosing a PoE switch, you usually need to consider the following issues:
How much power do I need to power the device?
How many devices can Power Over Ethernet switches power at most?
Number of interfaces required? Having a fiber optic port、With or without network management? Speed (10/100/1000M)? ……

Question three: Is Power Over Ethernet power supply stable?
Judging from the development time of this technology, it has been developed for many years. This can provide standard PoE power supply to a certain extent. Which is stable and safe enough to provide a certain guarantee.
Is the PoE switch or wire quality selected too low? Products plan design itself unreasonable?
The power supply distance has not been judged and set correctly? Or are there too many high-power devices connected, causing insufficient power supply? This may cause the PoE power supply to be unstable.

Question four: Are Power Over Ethernet power switches energy efficient?
One of the great advantages of this technology is energy saving. But in what aspects is energy saving reflected?
Worth mentioning that this product can automatically adjust power according to the power supply device.

Question five: When we use PoE power supply switches, should we choose the bigger the power, the better?
If we only pursue the improvement of the total power of these products. If we also ignore the relationship between power and port count that these products may have. In this case, when we pursue high power, the overall cost of the equipment we choose increases. The result is that the PoE switch chosen by the user is not practical and has low cost performance.
Therefore, during actual deployment, the power and quantity of PD devices should be determined first to make a judgment. Use your judgment to choose the most suitable PoE switch.
The above are five of the common questions about POE power supply.
