What does power adapter poe mean?
PoE stands for Power Over Ethernet, i.e. Active Power over Ethernet technology, which can simultaneously transmit data signals and provide power to network devices without modifying existing Ethernet cables.PoE power adapter realises power supply and data transmission of low-power network devices through a single network cable, simplifies the installation process, reduces costs, and is especially suitable for wireless network deployment.
Connection Methods of PoE Power Adapter
PoE power adapters are usually equipped with two interfaces, the data input interface and PoE power supply interface. The data input interface connects to the computer or switch, while the PoE power supply interface connects to the device that needs power supply.There are two main standards for PoE power supply: Alternative A uses 1, 2, 3, and 6 cores to supply power, connecting to a 100 Gigabit switch requires only 4 cores of cable, while connecting to a Gigabit switch requires all 8 cores of cable; Alternative B uses 4, 5, 7, and 8 cores to supply power, regardless of whether 100 Gigabit or Gigabit switch is used. Alternative B uses 4, 5, 7, and 8 cores for power supply, and requires 8 cores of network cable regardless of whether it uses a 100 Gigabit or a Gigabit switch.
Precautions for installing the PoE power adapter
When installing the PoE power adapter, you should pay attention to the following matters: avoid blocking the PoE connector or letting the impurity airflow come into contact with it; avoid placing it in a high-temperature, humid, vibrating, or dusty environment; avoid using adhesive tape when installing it and fix it with a cable tie instead; do not place more than one of them horizontally; do not let there be a source of heat within the surrounding area of 30 centimetres; and make sure that the length of the Ethernet cable is not more than 100 metres, and use the splitter if necessary; It is recommended to install the PoE power adapter in a well-ventilated place to facilitate heat dissipation.
