![]() IEEE 802.3af standard PoE switch single port output power is 15.4W, IEEE 802.3at standard PoE switch single port output power is 30W, IEEE 802.3bt (Type 3 PSE) standard PoE switch single port output power is 60W, IEEE 802.3bt (Type 4 PSE) standard PoE switch single port output power is 90W. In addition to choosing a standard PoE switch, you need to pay attention to the power required by PD devices. The biggest difference between non-standard POE switch and a standard POE switch is that: standard POE switch is an intelligent power supply, non-standard POE switch is vice versa, so it is easy to burn in the situation. The standard PoE switch can automatically connect to the network devices connected to it, and only network devices that support the PoE power supply PoE switch will start to supply power to protect the safety of the powered devices. When using a non-standard PoE switch, its power supply voltage and the voltage of the powered device must be the same. Non-standard PoE switches have security risks, such as burning out the network devices connected to them. Also, PoE switches can be divided into standard PoE switches and non-standard PoE switches. The power supply protocol supported by the switch needs to be consistent with the PD device. Before purchasing a switch, you need to determine what power supply protocols are supported by the PD device. Released under the Apache Licence, Version 2.The power supply standards for PoE switches are classified as PoE (IEEE 802.3af), PoE+ (IEEE 802.3at) and PoE++ (IEEE 802.3bt). ![]()
