When you’re building a robust and reliable network—especially one that includes outdoor access points, surveillance cameras, or long cable runs—surge protection isn’t optional. It’s a necessity. The Ubiquiti Networks ETH-SP-G2 Ethernet Surge Protector is purpose-built to safeguard your network from electrostatic discharge (ESD) and lightning-induced surges that can travel through Ethernet cables and damage your critical networking hardware.
This compact yet powerful protector is designed for plug-and-play simplicity, offering an easy-to-deploy solution that fits seamlessly into any network topology. Whether you’re managing a large enterprise deployment or a small outdoor Wi-Fi setup, the ETH-SP-G2 provides the level of protection your devices need—all without compromising on data speed or performance.
Ubiquiti Networks ETH-SP-G2 Ethernet Surge Protector – In-Depth Overview
The Ubiquiti Networks ETH-SP-G2 Ethernet Surge Protector (Part Number: ETH-SP-G2) is an advanced protection module designed to absorb and neutralize power surges that can damage expensive networking equipment. It features two RJ45 Ethernet jacks—one for input and one for output—making it incredibly easy to install between any two devices or between a device and a PoE injector.
This surge protector is engineered specifically for gigabit Ethernet networks, ensuring that it won’t introduce bottlenecks in data flow. Its passive design means it requires no power supply or configuration. It just works—silently protecting your infrastructure, 24/7.
Another standout feature is its compatibility with both indoor and outdoor setups. Housed in a rugged weather-resistant casing, the ETH-SP-G2 is ideal for mounting outside, close to the equipment that’s most vulnerable to environmental elements. It’s also compliant with industry-standard ESD protection levels, offering up to ±30kV air and ±30kV contact discharge protection, as per IEC 61000-4-2 standards.
Practical Applications
The primary role of the Ubiquiti Networks ETH-SP-G2 Ethernet Surge Protector is to defend your network devices—especially those installed outdoors—from electrostatic discharge and power surges. This includes devices like outdoor access points (e.g., Ubiquiti NanoStation, UniFi Mesh APs), IP cameras, and bridges that might be mounted on rooftops, poles, or other open areas.
Power surges are unpredictable and can happen due to lightning, faulty power infrastructure, or even improper grounding. By integrating ETH-SP-G2 units at strategic points in your network—especially where Ethernet cables enter buildings or connect to outdoor devices—you significantly reduce the risk of hardware failure, data loss, and costly downtime.
Ethernet Ports and Connectivity
The ETH-SP-G2 includes two shielded gigabit Ethernet jacks, designed to support high-speed communication while protecting connected devices. One port connects to the upstream network (like a switch or router), and the other connects to the downstream device (such as an access point or IP camera).
Because the device supports passive PoE passthrough, it can also be used in PoE-powered installations without interrupting power flow. It ensures your powered devices continue operating while staying safe from ESD and surges.
Feature Highlight: Passive Plug-and-Play Protection
One of the key reasons IT managers and installers prefer the ETH-SP-G2 is its completely passive design. There’s no need for configuration, no software interface, and no maintenance. Installation is as simple as connecting two Ethernet cables. Once installed, the device immediately begins protecting your network from surges.
Its passive nature also means zero power consumption, which is ideal for remote deployments where power efficiency is critical.
Use Case: Outdoor Wi-Fi Installations
Imagine you’re installing a Ubiquiti outdoor UniFi AP on the side of a building. It’s connected to your indoor network via a long Ethernet cable. During a storm, a lightning strike nearby induces a surge that travels down that cable. Without protection, your access point—and potentially the entire switch it connects to—could be fried.
With the Ubiquiti Networks ETH-SP-G2 Ethernet Surge Protector installed between the AP and your network core, that surge is safely discharged before it can reach your sensitive equipment.
