研华网管型EKI-7708E-4FI交换机产品简介：

EKI-7708E-4F/4FI provides user with abundant ports to connect to many devices and with 4 Fast Ethernet ports and 4 SFP (mini-GBIC) ports. It is embedded with Advantech’s IXM function, which can benefit users for fast deployment and can dramatically save engineers time and cost. The EKI-7708E series also supports NMS to help IT managers with networking maintenance and failure prevention. Finally, the EKI-7708E series is equipped with X-Ring Pro which can achieve ultra high speed recovery times of less than 20 ms to ensure network stability. The switch also features a wide -40° to 75°C operating temperature (EKI-7708E-4FI) and NEMA TS2 rating, making the switch ideal solution for use in traffic applications. EKI-7708E-4F/4FI has successfully passed the EN50121-4 European railway standard requirements for emissions and railway platform and trackside deployment.
