研華網(wǎng)管型工業(yè)以太網(wǎng)交換機簡介：

EKI-7720G-4F/4FI supports 16 Gigabit Ethernet ports and 4 SFP (mini-GBIC) ports. It can provide users abundant ports to connect many devices. Besides, it is embedded with Advan-tech IXM function, this can benefit users for fast deployment and can dramatically save engineers time and costs. The EKI-7720G series also supports NMS to help IT managers with networking maintenance and failure prevention. Finally, the EKI-7720G series is equipped with X-Ring Pro which can achieve ultra high speed recovery time of less than 20 ms to ensure network stability. The switch also features a wide -40° to 75°C operating temperature(EKI-7720G-4FI).
