The PCIe 421 is a perfect combination of 4 Gigabit controllers, by adding four separate Gigabit network ports to the client, server, or workstation through one PCI Express slot provides connectivity to multiple networks. This Gigabit Ethernet Network card utilizes the Intel i210/i211 chipset delivers powerful connectivity with advanced features such IEEE802.3az for energy saving. The EEE standards for energy-efficient ethernet so that during periods of low network activity EEE reduces the power consumption of an Ethernet connection by negotiating with the switch port to transition to a lower power idle state. Compliant with 802.3X/ad/Q standard, it provides an effective upgrade to 4 RJ45 network ports with 10/100/1000Mbps for high-speed connectivity. It also supports IEEE1588 Timestamping enables high precision time synchronization over the Ethernet. The IEEE 1588 specifies the proto-col used to ensure that synchronization requirements are met for time-sensitive applications. 

This network adopter supports advanced features designed to boost the performance and enhanced capabilities you need for reliable network connections. This versatile four ports PCIe network card is ideal for many embedded applications such as industrial automation, in-vehicle infotainment, medical, print imaging, telecommunications infrastructure, etc. Moreover, its unique, multi-ethernet-port topology structure can largely reduce hardware resources and improve compatibility while several ethernet cards are inserted.
