Check your required Ethernet speed, number of ports, connection type, available PCIe slot and operating system. Your switch, cabling and other connected equipment should also support the speed you intend to use. If you need help choosing, share your system model and requirements with us before ordering.

Compatibility depends on the specific card and your system. Before purchasing, check the PCIe slot requirements, available installation space, bracket size, operating system and driver support listed for the model.

Operating system support varies by model and chipset. Please check the individual product specifications for supported Windows, Linux, server or other operating system versions. For a particular OS version, confirm compatibility before purchasing.

RJ45 network cards connect through compatible copper Ethernet cables. Cards with SFP, SFP+, SFP28, QSFP+ or QSFP28 ports use compatible transceivers or direct-attach cables, depending on the model. Select the connection type that matches your switch and network infrastructure.

Package contents vary by model. Check the product page to confirm whether transceivers, cables, low-profile brackets or other accessories are included or need to be purchased separately.

These cards add connectivity to a compatible system. Serial and Parallel cards connect devices that require RS-232 or LPT interfaces, while USB and Type-C cards provide additional USB ports. Check the model’s port types, supported speeds and device requirements before choosing.
