MicroConnect MC-PCIEX1-82576-D - Network Interface Card

The MICROCONNECT MC-PCIEX1-82576-D dual-port Gigabit Ethernet network card (PCIe x1, Intel JL82576EB) provides wired LAN connectivity for desktop PCs and servers. This internal interface card fits into a standard PCI Express Gen2 x1 slot and features two independent RJ45 ports. Each port supports data transfer rates of up to 1000 Mbit/s. The card is designed specifically for wired networks and does not include Wi-Fi or Bluetooth functionality.

The Intel JL82576EB chipset manages data traffic across both interfaces. Thanks to its low-profile form factor, the card is suitable for compact cases, mini servers, and network appliances. At 70 grams, it adds negligible weight to the host system. The card is compatible with consumer systems from Windows 7 through 10, as well as enterprise platforms including Windows Server 2008 to 2019, Linux kernel 5.x or newer, and VMware ESXi 6.7/7.0.
