A MikroTik device with a port identified as PoE-In means that this device can be powered by this port; generally, all devices that support PoE power have this label on the ether1 port.

The ports identified as PoE-Out are used to power other equipment that connects to these ports. This will only be possible if the equipment that connects to these ports supports PoE power.

Los términos PoE-In y PoE-Out en los equipos MikroTik se refieren a la capacidad de recibir (PoE-In) y proporcionar (PoE-Out) alimentación eléctrica a través del cableado Ethernet, según el estándar Power over Ethernet (PoE).

Esta funcionalidad permite simplificar la instalación de dispositivos de red, eliminando la necesidad de una fuente de alimentación eléctrica dedicada para cada dispositivo, al poder transmitir tanto datos como energía eléctrica por el mismo cable. Aquí te explico con más detalle:

PoE-In (Power over Ethernet Input)

• Definition: Indicates that the device can be powered over an Ethernet cable from a PoE power source, such as a PoE injector or PoE switch. This is useful for devices installed in locations where it would not be practical or possible to access power outlets.
• typical use: In network devices such as IP cameras, wireless access points, and some models of MikroTik routers and switches that can operate without the need for a conventional power connection, they only require an Ethernet cable that carries both data and power.

PoE-Out (Power over Ethernet Output)

• Definition: Means that the device can supply power to other PoE-compatible devices through one or more of its Ethernet ports. This allows other network devices to be powered directly from the MikroTik equipment, without the need for individual power supplies for each device.
• typical use: Used to power other PoE devices such as access points, IP cameras, or even other routers/switches. This is especially useful in deployments where you want to minimize wiring and electrical infrastructure, such as telecommunications towers, security camera deployments, or in the implementation of extensive WiFi networks.

Considerations

• PoE Compatibility and Standards: There are several PoE standards (such as 802.3af, 802.3at, and 802.3bt), which support different power levels. It is important to ensure that both the device supplying the power (PoE-Out) and the device receiving it (PoE-In) are compatible in terms of power standards and requirements.
• Power Limitations: PoE-Out devices can only supply a limited amount of power, determined by their design and the PoE standard they support. It is crucial not to exceed this capacity to avoid performance problems or damage to the equipment.
• Wiring: Using quality cabling and ensuring it is properly installed is critical to PoE performance, especially in deployments where power is transmitted over long distances.

In summary, the availability of PoE-In and PoE-Out ports on MikroTik equipment offers great flexibility in designing and deploying network infrastructures, allowing for easier installation and reducing the need for dedicated power supplies and outlets for each device. In the net.
