The ETH-SP is engineered to protect any PoweroverEthernet (PoE) or nonPoE device with connection speeds of up to 1 Gbps. Models: ETHSP. Damaging electrostatic discharge attacks and surges are diverted to the ETH-SP and safely discharged into the ground, so network devices are protected. All Ubiquiti airMAX devices are equipped with built-in ESD protection, so the ETHSP adds another layer of protection to your outdoor, high-speed network. Connect the ground and Ethernet cables in between your network devices.
