The POE switch has a very important hidden indicator, only the gods know it! I only tell you once! Remember it! Next, let’s take a look at the hidden indicators of POE switches with the editor of Feichang Technology!Serial port
A very important hidden indicator of the POE switch is the total power of the POE power supply. Under the IEEE802.3af standard, if the total POE power of a 24-port POE switch reaches 370W, it can supply 24 ports (370/15.4=24), but if it is in accordance with the IEEE802.3at standard, the maximum If the power supply is 30W, it can only supply power to 12 ports at the same time (370/30=12).serial to wifi converter
However, in actual use, the maximum power consumption of many low-power devices is relatively low. For example, the power of a single-frequency AP is 6~8W. If each POE port reserves the power supply according to the maximum power at this time, a The POE power of some ports cannot be used up, while the power of some ports cannot be distributed. Many POE switches support dynamic power allocation (DPA). In this way, each port only allocates the power actually used, so that the power supply of the POE switch can be used more efficiently.
