Dual-port 10GbE server adapter

This PCIe 3.0 x4 network card uses the Intel X550-AT2 controller to provide two RJ45 ports for copper-based 10 Gigabit Ethernet. It targets administrators upgrading rack-mount or tower servers that need high-throughput links over existing Cat6a or Cat7 cabling. Low-profile and full-height brackets are included so the same card fits standard and slim chassis.

Speed headroom from 100 Mb to 10 Gb

Each port auto-negotiates down through 5 GbE, 2.5 GbE, 1 GbE and 100 MbE, letting the card serve mixed-speed segments without extra hardware. The x4 PCIe 3.0 interface supplies enough bandwidth for line-rate traffic on both ports simultaneously. Throughput drops only when the host bus is limited to PCIe 1.1 or 2.0 speeds.

Passive cooling in typical server airflow

The card ships without an active fan and relies on chassis airflow across its heatsink; in normal rack environments it runs silently. Power draw stays within the PCIe slot specification, so no auxiliary connector is required. Installers should verify that their enclosure provides adequate front-to-back airflow for sustained loads.

Questions about this item

Will the PCIe 3.0 x4 interface work in my older server that only has PCIe 2.0 slots?

Yes, the card is backward compatible with PCIe 1.1 and 2.0 and fits x4, x8, or x16 slots, so it will operate in a PCIe 2.0 slot at the slot's maximum speed.

How can I verify the Intel X550-AT2 controller is recognised and the dual RJ45 ports are linking at 10GbE after installation?

Check Device Manager or run lspci to confirm the Intel X550-AT2 appears, then ensure each port shows a 10GbE link speed and the driver version matches the OS release from Intel's site.

Does the box include both mounting brackets or do I need to buy a low-profile bracket separately for my slim chassis?

The package includes both a full-height bracket and a low-profile bracket, so no extra bracket purchase is required for standard or slim systems.
