Adaptador PoE MikroTik GESP+POE-IN

The MikroTik GESP+POE-IN is a passive PoE adapter with built-in surge protection, designed to supply power to network devices while reducing the risk of damage from lightning strikes and electrostatic discharge. It works together with the MikroTik GESP surge protector to protect both mast-mounted antennas and ground-level switches. The unit supports Ethernet LAN data rates of 10/100/1000 Mbit/s and complies with IEEE 802.3af/at standards, providing up to 700 V PoE voltage for reliable power delivery.

Advantages

The GESP+POE-IN combines passive PoE injection with surge protection in a compact, weather-resistant design that complements the GESP surge protector for end-to-end cable protection. It supports gigabit Ethernet for uninterrupted data transmission while supplying power, and its surge protection capability helps absorb multiple impacts from lightning or static discharges. Installation is simple and it is suitable for use with mast-mounted and ground-level equipment when properly grounded.

Suitable for

• Powering mast-mounted antennas and remote network devices
• Providing PoE power to access points, IP cameras, and switches
• Deployments that require surge protection on long Ethernet runs

Key specifications

• Brand: MikroTik
• Model: GESP+POE-IN
• Ethernet LAN (RJ-45) ports: 2
• Data rates: 10/100/1000 Mbit/s
• PoE voltage (surge protection rating): up to 700 V
• Standards: IEEE 802.3af / IEEE 802.3at (passive PoE compatible)

How to use

Install the GESP surge protector at the mast near the antennas and mount the GESP+POE-IN injector below the mast or in a weather-protected location near the powered equipment. Connect the network cable from your switch to the injector’s data input and run a shielded Ethernet cable from the injector to the antenna or PoE device. Ensure all grounding wires are securely attached to a proper ground point, such as the mast, rackmount, or building grounding system. After a surge event, inspect both GESP units for visible damage and replace them if their protective capability appears compromised.

Recommendations

For maximum protection, use a surge protector on both ends of long Ethernet cables and secure GESP units with PVC zip ties without over-tightening. Regularly verify grounding connections and inspect the devices after any strong electrical event to ensure continued protection.
