When a MikroTik device has PoE (Power over Ethernet) network ports, it means that the device is designed to provide electrical power over the same network cable that is used for data transmission.

This allows connected devices, such as access points, surveillance cameras, IP phones, and other PoE-enabled devices, to receive power and transmit data using a single Ethernet cable, simplifying network infrastructure and reducing installation and maintenance costs.

Functionality of PoE Ports in MikroTik

1. Power and Data in a Single Cable: Connected devices can operate without the need for an additional power source near them, which is ideal for locations where it would be difficult or expensive to power each device.
2. Types of PoE in MikroTik:
   • Passive PoE: Many MikroTik devices offer passive PoE, meaning they transmit electricity on certain pins of the Ethernet cable at a fixed voltage (such as 24V), without any communication between the powering device and the receiving device.
   • 802.3af/at PoE (Active PoE): Some more advanced models support active PoE, which complies with IEEE standards and can negotiate the amount of power supplied with the device receiving the power, providing more flexible and secure power.

Advantages of Using PoE in MikroTik Equipment

• Installation Simplicity: Reduces the need for electrical outlets and allows devices to be installed in inaccessible places or where there is no nearby electrical infrastructure.
• Efectivity cost: Decreases wiring and maintenance costs by eliminating the need for additional electrical cables and the professional installation associated with them.
• Flexibility and Scalability: Makes it easy to expand networks and install new devices without worrying about power availability at each location.

Considerations When Using PoE

• Compatibility: Make sure that both the device providing the power (such as the switch or MikroTik router with PoE) and the receiving device support the same PoE standard and type.
• Energy Requirements: Check the power capacity of the PoE port on your MikroTik equipment to ensure it can supply enough power to operate the connected device properly.
• Security: Using PoE with equipment that is not designed for it can damage the devices. It is always important to use equipment that meets the necessary technical specifications.

PoE ports on MikroTik equipment offer a powerful and flexible solution for powering network devices, making the deployment and management of network infrastructures more efficient and accessible.
