Intel E1G42ETBLK PCIe X4 Dual Port Gigabit Network Card

The Intel E1G42ETBLK PCIe X4 Dual Port Gigabit Network Card is a two-port Intel Gigabit Ethernet adapter that installs in a PCIe x4 slot to provide additional wired network connectivity in a desktop, workstation, or server system. Part of Intel's Gigabit ET family, it offers two independent Gigabit Ethernet ports, enabling separate network paths or increased throughput within a single host. The PCIe x4 interface supports expansion without sacrificing other PCIe resources, making it suitable for setups that need extra network interfaces while maintaining bandwidth for other devices. The E1G42ETBLK model designation identifies this PCIe card within Intel's Ethernet lineup, reflecting standard form factor and compatibility with typical PCIe-equipped systems. This card is commonly used to expand connectivity for tasks such as network segmentation, dual-network configurations, or testing across multiple networks from one machine. With two Gigabit ports, it allows administrators to connect to separate networks, VLANs, or test environments without swapping out existing adapters.
