In the previous article, we discuss five of the common problems with POE power supply. We will cover the rest one by one in this article.

Question six: What benefits does a PoE power supply solution offer?
1. Streamlines cabling and reduces labor expenses
2. Secure and user-friendly
3. Facilitate remote management
Question seven: What are the disadvantages of PoE power supply technology in engineering applications?
1. Inadequate energy, the receiver cannot be operated
2. Weak risk diversification ability
3. Equipment and maintenance may be higher than other equipment.
Compared with other power supply methods. This power supply technology may increase the workload and cost of after-sales maintenance. Independent power supply has the best stability and security in safety.
The safe transmission distance of power supply of this technology is generally 100 meters. Recommended to use Category 5e all-copper network cable.
Can standard Ethernet cables transmit DC power over long distances? The safe transmission distance of power supply of this technology is generally 100 meters.
The data transmission distance determines the maximum transmission distance of a PoE switch, not imagination. When the transmission range surpasses 100 meters, issues such as data latency, packet loss, and so on may arise. Therefore, to better ensure data transmission, the transmission distance should not exceed 100 meters.
Night of Queries: How can one differentiate between standard PoE and non-standard PoE?
01 See specifications
02 Use professional testing methods to test whether the network cable always has voltage output.
Question ten: So the standard PoE power supply switch must have high reliability?
The dependability of machinery is intimately connected to the conditions of its usage environment. Commercial switches are typically appropriate for indoor applications, whereas industrial switches are usually ideal for outdoor applications. Because of differences in use environments, they also have different requirements for reliability.
About the reliability of commercial POE switches? This reliability mainly consists of two parts. One component is the switching segment, primarily made up of (PCB, switch chip + PoE chip, additional electronic materials). A portion of it involves using an integrated or external power source for POE.
Since the power source powers the entire device, its dependability is of utmost importance. Two relatively simple solutions exist to determine the power reliability of POE power supply switches:
01 Ensure to check meticulously if the power supply possesses 3C certification and pertinent details about the manufacturer.
02 Test the power supply surface temperature
The above are some common questions and answers about POE power supply.
