Dual 10GbE RJ45 Adapter

The LR-LINK LRES1025PT is a dual-port 10GbE network interface card built around the Intel X550 controller. It connects through a PCIe 2.1 x8 slot and is compatible with x16 slots including low-profile and full-height brackets. The card targets servers and workstations that need copper-based 10Gb Ethernet connectivity.

Suited for Multi-Speed Copper Networks

This card suits administrators who need auto-negotiation across 100MbE, 1GbE, 2.5GbE, 5GbE and 10GbE over standard RJ45 cabling. Driver support covers Windows 7 through 11, Windows Server 2008 R2 through 2022 R2, Linux kernel 4.x or later, CentOS/RHEL 7.x or later, Ubuntu 16.x or later, FreeBSD 9 through 11 and VMware ESXi 4.x or later. Buyers who require fibre SFP+ connectors or single-port 10GbE should look at a different adapter.

PCIe 2.1 x8 Interface Decides Fit

The single specification that determines compatibility is the PCIe 2.1 x8 bus requirement at 8.0 GT/s. The card will negotiate down to lower speeds but needs an x8 or x16 slot that supports PCIe 2.1 or newer. Operating temperature range is 0°C to 55°C with humidity tolerance up to 90 per cent non-condensing.

Questions about this item

Will the PCIe 2.1 x8 interface run at full speed in my older motherboard that only has PCIe 2.0 x16 slots?

The card is compatible with PCIe x16 slots and auto-negotiates link speed, so it will operate at the slot's maximum capability.

How can I verify both 10Gb RJ45 ports are linked at 10 Gbps after installing the Intel X550 driver?

Check the adapter properties in your OS network settings; each port should report a 10 Gbps link speed when connected to a 10G switch with Cat6a or better cabling.

Does the box include both low-profile and full-height brackets for the dual-port LRES1025PT?

The adapter supports both bracket types for installation flexibility; the exact bracket contents are determined by the specific package variant.
