Office Building Indoor Ethernet Surge Protection Device 16 Port Rack Mount 100M
LS-100M Series Rack-Mount Network Signal Surge Protectors are designed for 100 BASE-T 802.3 computer network systems, suitable for installation in LPZ 2-3 and subsequent lightning protection zones. They feature a standard 19” 1U rack design, making them ideal for high-density low-speed network environments such as security monitoring rooms and small data centers.
Integrated with multi-channel independent protection circuits, the products minimize mutual interference between ports. The unique anti-interference wiring design meets 100M network communication requirements, while the single-stage high-energy device parallel protection circuit delivers low residual voltage. POE models support 48Vdc POE power supply, catering to POE-enabled devices such as IP cameras and wireless access points.

Notices
●Ensure the rack mounting space meets 1U (44mm) height requirement.
●For POE models, confirm the POE power supply voltage matches 48Vdc.
●Use Cat-5 or higher grade cables to ensure 100Mbit/s transmission speed.
●Properly ground the SPD to guarantee surge diversion; ground resistance ≤4Ω is recommended.
●Regularly inspect the ports for loose connections or physical damage.
●Failure is indicated by signal interruption; troubleshoot or replace the product if multiple ports fail.
FAQ
Q1: What standards does this product comply with?
A1: It complies with GB/T 18802.21-2016 national standard and IEC 61643.21 international standard.
Q2: Can it protect both signal and POE power lines?
A2: Yes, POE models provide separate protection for 100M network signals (lines 1-2､3-6) and POE power lines (lines 45-78).
Q3: What is the difference between 16-port and 24-port models?
A3: The only difference is the number of protected ports (16 vs 24), with all other performance parameters identical.
Q4: Is the product suitable for outdoor use?
A4: No, it is designed for indoor use (IP20) in network cabinets and equipment rooms.
Q5: What is the service life of the product?
A5: Under normal operating conditions, the service life is 5-8 years. Regular inspection of ports and wiring is recommended
