ORing's CompactPCI series Ethernet switches are designed for industrial applications, such as factory automation, vehicle, and railway applications. CPGS-9120-C is CompactPCI managed redundant ring Ethernet switch with 12x10/100/1000Base-T(X) ports in CompactPCI socket which is specifically designed for the toughest and fully compliant with EN50155 requirement. The switch support Ethernet Redundancy protocol, O-Ring (recovery time < 30ms over 250 units of connection) and MSTP (RSTP/STP compatible) can protect your mission-critical applications from network interruptions or temporary malfunctions with its fast recovery technology. CPGS-9120-C supports wide operating temperature from -40 oC to 70 oC which can fulfill most of the requirement of operation environment. Besides the Web-based interface, Telnet and console (CLI) configuration, CPGS-9120-C can also be managed centralized and conveniently by Open-Vision. Therefore, the switch is one of the most reliable choices for rolling stock and highly-managed Ethernet application.
