POE switch hidden indicators you have to know

POE switches have a very important hidden indicator, only the great gods know! I only tell you once! Remember!

A very important hidden indicator of the POE switch is the total power supplied by the POE. Under the IEEE802.3af standard, if the total power of a POE power supply of a 24-port POE switch reaches 370W, then it can supply 24 ports (370/15.4=24), but if it is a single port according to the IEEE802.3at standard, the maximum is The power supply is calculated at 30W, and at the same time, only 12 ports can be powered (370/30=12).

However, in actual use, the maximum power consumption of many small power devices is relatively low. For example, the power of a single-frequency AP is 6~8W. If each POE port reserves power at the maximum power, it will appear. Some port POE power is not used, and some ports are not divided into power. Many POE switches support Dynamic Power Allocation (DPA). In this way, each port is only allocated the actual power used, so that the power of the POE switch can be utilized more efficiently.

Let's make a hypothesis, if we use the 24-port POE switch TBC-PS5624U-2GF2GE and the single-band panel AP TBC-MB2150X. We assume that the total machine POE power of the TBC-PS5624U-2GF2GE is 185W (Note: the Tianbo 24-port POE switch TBC-PS5624U-2GF2GE has a total power of 380W). If the power is calculated according to the distribution of 15.4W per port, only It can supply 12 ports, and after dynamic power allocation, because the maximum power consumption of the TBC-MB2150X is 7W, the TBC-PS5624U-2GF2GE can supply 24 panel APTBC-MB2150X (185/7=26.4).

Tianbo intelligent POE switch supports IEEE 802.3af/IEEE802.3at international standard, single port power supply output power 15.4W/25.5W; support 250 meters transmission intelligent power supply will never burn machine; welcome friends to call us.
