Important Compatibility Notes

• Cable Recommendation: For 10Gbps speeds, use Cat6a or Cat7 Ethernet cables. Cat6 cables may support shorter distances for 10G, but Cat6a/Cat7 are recommended for stable performance.

• PCIe Slot Requirement: Requires an available PCIe x4, x8, or x16 slot. Not compatible with legacy PCI slots.

• Driver Installation: Windows 10/11 and Server 2019/2022 may automatically install drivers. For Linux Kernel 5.x or custom NAS systems, you may need to manually install drivers from the Realtek chipset manufacturer's website

• Not a WiFi Card: This is a wired Ethernet adapter only.

1. Power off your PC or NAS and disconnect the power cable.

2. Insert the card into an available PCIe x4, x8, or x16 slot and secure it with a screw.

3. Attach the appropriate bracket (full-height or low-profile) if needed.

4. Connect an Ethernet cable to the RJ45 port.

5. Power on the system and install drivers if the operating system does not detect the card automatically.
