  • Industrial Layer 2 Managed POE Switch 4x10/100/1000Base-TX POE (2x90W Ultra POE++ Ports + 2x Standard POE Ports) + 2x1000Base-FX SFP, without industrial SFP module and Industrial power supply

G-NET G-IMS-2GX4GPB-SFP Layer 2 Managed industrial PoE Switch supports 4x10/100/1000Base-TX POE ports (2x90W Ultra POE++ Ports + 2x Standard POE Ports) and 2x1000Base-FX SFP ports. Integrated with high performance, high security and multiple services, this switch provide full line-rate layer 2 switching and complete QoS policies to ensure the undelayed transmission of key data by applying different traffic classification rules to different applications.Bisides,the switches are classified as power source equipment (PSE), can be used to power IEEE802.3af/at standard devices (PD), eliminating the need for additional wiring.Its dustproof fully sealed structure (IP40 protection grade), over- current,over-voltage and EMC protected,redundant double power input, -40~80℃ wide operating temperature can help system main tenancy personnel monitor the network operation, which can work reliably in harsh and dangerous environment.It supports various rich protocols, such as integrated switching and security, support public Ethernet multi-ring protection technology (ERPS), greatly improve network flexibility and enhance the reliability and security of industrial network
