Under the development trend of the Internet of everything to build a smart world of things, users’ demand for IoT devices is increasing, and POE switches have become an effective medium to provide power and data transmission for PD devices through network cables. PoE switches allow devices such as IP phones, IP cameras, wireless access points, or POE lighting to receive data and power through a single network cable, eliminating the need for a separate power cord. So how does a POE switch power these devices? Does it cause damage to connected devices? This paper will discuss the series of problems in detail.
What standards does Power over Ethernet follow? POE power supply standard overview.
POE switch in the POE system can act as a power supply (PSE) device, according to different Ethernet power supply standards for the receiving end (PD) equipment for power supply, help home, enterprise, campus, shopping malls and other environments in the security monitoring system installation and management.
It should be noted that the IEEE 802.3af and IEEE 802.3at standards are power over Ethernet standards that can be supported by most PD devices on the market, so POE switches and POE+ switches are widely used.
POE power supply is roughly the above knowledge points, about the switch series in the above mentioned in Shenzhen HDV Phoelectron Technology Ltd. belongs to the popular class of communication products, such as: Ethernet switch, Fibre Channel switch, Ethernet Fibre Channel switch, etc., the above switches can be used in a variety of environments, to provide more choices for users with different needs, welcome to come to understand, we will provide the best quality service.
