4FE + 2 SFP Lite-Managed Ethernet Switch



IES-2042PA is a Lite-Managed Redundant Ring Ethernet switch. With the very compact size of the housing, you can install IES-2042PA easily. In addition, it also supports Ethernet Redundancy protocol, O-Ring (recovery time < 10ms over 250 units of connection), O-Chain and STP/RSTP (IEEE802.1w/D) can protect your mission-critical applications from network interruptions or temporary malfunctions with its fast recovery technology. IES-2042PA provides the setting ability of Web-GUI and Windows Utility and also supports the simple DIP-Switch setting function which offers great flexibility to set up the Ring. With it's rigid IP-30 housing design, it can operate under harsh environment. The feature of wide operating temperature range from -40 to 70°C can satisfy most requirement of operation.
