Questions & Answers
What is the UBNT Networks ETH-SP-G2 Ethernet Surge Protector Gen 2?
The UBNT ETH-SP-G2 is a high-performance Ethernet surge protector that safeguards network devices from voltage spikes and electrostatic discharge (ESD) by providing Ethernet-to-Ethernet grounded protection.
How does the ETH-SP-G2 protect my network equipment?
The ETH-SP-G2 diverts transient voltages and ESD pulses to ground through internal gas discharge tubes and diodes, preventing damage to connected switches, cameras, and radios.
Which Ethernet cables and PoE standards are supported by ETH-SP-G2?
The surge protector supports Cat5e/Cat6 cables and fully complies with IEEE 802.3af/at standards, preserving PoE+ power delivery up to 30 W per port.
Do I need a separate ground connection for the ETH-SP-G2?
Yes. For optimal surge protection, connect the ETH-SP-G2’s ground terminal to a low-impedance earth ground using a minimum 14 AWG copper conductor.
Can I install the ETH-SP-G2 outdoors?
Yes. The IP55-rated housing and corrosion-resistant materials allow outdoor mounting in temperatures from -40 °C to 70 °C without compromising protection.
Does the ETH-SP-G2 affect network speed or latency?
No. The protector features a low capacitance design (<5 pF), ensuring full Gigabit throughput and negligible latency impact on data transmission.
What are the physical dimensions and mounting options?
The unit measures 125 × 61 × 34 mm and includes DIN-rail clips and wall-mount flanges for versatile industrial or rack-mount installations.
How do I know when the ETH-SP-G2 needs replacement?
An integrated status LED remains green under normal operation; a red or unlit LED indicates protective element fatigue and signals replacement.
Is the ETH-SP-G2 UL or IEC certified?
Yes. The device meets UL 1449 Type 4 and IEC 61643-21 standards for Ethernet surge protection in industrial and commercial applications.
Can ETH-SP-G2 protect against direct lightning strikes?
While designed to handle high-energy transients, direct lightning currents exceed any inline protector’s capacity; it is best used in combination with a primary lightning arrestor.
What is the maximum surge current rating of the ETH-SP-G2?
The protector is rated for 10 kA (8/20 µs waveform) surge current per line, delivering robust defense against severe voltage transients.
Is the ETH-SP-G2 compatible with PoE cameras and wireless radios?
Yes. It preserves full PoE/PoE+ functionality and maintains Gigabit connectivity for IP cameras, access points, and point-to-point radios.
How many ports does the ETH-SP-G2 provide protection for?
The ETH-SP-G2 protects one Ethernet link with an RJ45 in-line design, making it ideal for point-to-point device installations.
Does the ETH-SP-G2 require maintenance?
No routine maintenance is needed. Regularly inspect the status LED and ground connection for optimal performance and safety.
What is the warranty period for the ETH-SP-G2?
UBNT offers a two-year limited warranty covering manufacturing defects and surge protection failures under normal operating conditions.
How do I install the ETH-SP-G2 in my network setup?
Insert the ETH-SP-G2 inline between your switch and device, secure the ground lug to earth ground, then verify the status LED is green before powering equipment.
