Product Description
The IS3008G4BP-8P-M12-DC series is an industrial Ethernet switch designed specifically for the rail transit industry, strictly complying with industry standards such as EN50155 and EN50121. This series features a high-strength metal housing and compact structure, supporting wide-temperature operation from -40℃ to 75℃ and IP40 high protection rating, with excellent

vibration resistance, dustproof, and waterproof performance, suitable for harsh environments such as onboard applications.

Core Advantages
Rail-Grade Reliability  : Fully complies with rail transit industry standards such as EN50155 and EN50121, supports wide-temperature operation (-40℃~75℃) and IP40 protection rating, with M12 interface configuration effectively resisting vibration and shock, ensuring uninterrupted network operation during train operation.
Flexible Power Supply    : Supports IEEE 802.3at/af standards, with maximum PoE output of 30W per port, enabling centralized power supply for multiple PD devices (such as onboard cameras and wireless APs), simplifying cabling.
Intelligent Network Management: Supports Layer 2/Layer 3 network protocols, including RSTP, EAPS, ERPS ring network redundancy protocols (<20ms self-healing), and DHCP Option82, meeting high real-time and reliability networking requirements.
Compact and Rugged Design: Wall-mount installation and optimized dimensions fit limited spaces, with metal housing and fully sealed interface design ensuring stable operation under strong vibration and high electromagnetic interference environments.
Typical Applications
Onboard Passenger Information System (PIS), Video Surveillance System (CCTV)
Train control and diagnostic networks, real-time data acquisition and transmission
Rail transit signal systems, onboard wireless coverage
Automation control and communication networks in harsh industrial environments

The IS3008G4BP-8P-M12-DC series, with its passive bypass function, ensures the network remains operational even during multi-point failures. With high reliability, strong adaptability, and intelligent management features, it provides 24/7 network connectivity for rail transit and harsh industrial scenarios, contributing to the stable realization of smart transportation and industrial interconnection.
