10Gb dual-port RJ45 server adapter

This 10Gtek network card delivers two 10 Gbps copper ports driven by an Intel X540 controller. It targets servers and workstations that need 10GBASE-T connectivity over Category-6A cabling up to 100 m or Category-6 up to 55 m. The PCIe 2.1 x8 interface fits x8 or x16 slots and includes both standard and low-profile brackets for flexible chassis mounting.

Check slot width and OS driver support

Verify the host has a free PCIe x8 or x16 slot running at 5.0 GT/s and that the operating system is among the listed Windows Server 2003, 2008, 2012, Windows 7, 8, 10, Linux or ESX/ESXi. Windows 11 requires manual driver setup as noted by the supplier. The card does not support hot-swapping, so plan for a shutdown during installation.

Fits standard and low-profile builds

The included brackets let the adapter sit in full-height or compact server cases without blocking adjacent slots. Dual RJ45 ports free up separate single-port cards and consolidate 10 GbE links for iSCSI, FCoE or NFS storage traffic. Operating temperature range is 0 °C to 55 °C, so ensure adequate airflow in dense rack environments.

Questions about this item

Does the card ship with both a standard and a low-profile bracket, or do I need to buy a bracket separately?

The package includes a full-height bracket and an extra low-profile bracket so the adapter fits either a regular or a small-form-factor case without extra parts.

Should I choose the dual-port RJ45 version for Cat 6A runs up to 100 m or the single-port model for shorter Cat 6 links?

This model provides two RJ45 ports; each supports Cat 6A to 100 m and Cat 6 to 55 m, giving full 10 Gbps on both connections.

Will the advertised 10 Gbps actually appear in Windows 11 once the driver is installed correctly?

Yes, the Intel X540 controller delivers 10 Gbps line rate on Windows 11 after the proper driver setup, and the PCIe 2.1 x8 interface supplies enough bandwidth for both ports simultaneously.
