The Ubiquiti ETH-SP-G2 is a Gigabit Ethernet surge protector designed to protect outdoor network devices from damaging electrostatic discharge (ESD) and power surges. It's an essential accessory for outdoor network installations, especially for wireless internet service providers (WISPs) and surveillance systems.

Key Features and Specifications

• ESD and Surge Protection: The primary function of the ETH-SP-G2 is to provide a low-cost, effective way to absorb transient currents from surges and ESD events, and safely discharge them to the ground. This adds an extra layer of protection to devices that may already have built-in ESD protection, such as Ubiquiti's airMAX products.

• Gigabit Connectivity: The "G2" in the model name signifies it is the second generation and supports Gigabit Ethernet speeds (10/100/1000 Mbps). This ensures that it won't be a bottleneck for high-speed network connections.

• PoE and Non-PoE Compatibility: It is engineered to protect both Power over Ethernet (PoE) and non-PoE devices. It works with both passive PoE and IEEE 802.3af/at (active PoE) standards.

• Easy Installation: The device is designed for simple, "plug-and-play" installation. It has two passive, surge-protected RJ45 connections, and can be mounted on a pole or a wall. To be effective, it must be properly grounded. Ubiquiti recommends installing two ETH-SP-G2 devices for maximum protection: one near the outdoor device (like a CPE or camera) and another at the point where the cable enters the building.

• Durable Design: It has a compact, weatherproof enclosure that is built to withstand harsh outdoor environments.
