Dual-Port 10G PCIe X8 Network Card

The C&N ST7280-X550AT2 adds two 10 GbE RJ45 ports to a desktop or server through a PCIe 3.0 x8 slot. It uses the Intel X550-AT2 controller to deliver multi-gigabit speeds of 10G, 5G, 2.5G, 1G and 100 Mb/s over copper cabling. This adapter targets IT teams and power users who need high-throughput wired links for file servers, backup targets or virtualisation hosts.

Compatibility checklist before ordering

Verify that your motherboard has a free PCIe 3.0 x8 or x16 slot; the card is not compatible with x4 or x1 slots. Confirm your operating system appears in the supported list, which includes Windows 7 SP1 through Windows 10 and Server 2008 R2 through 2012 R2, Linux kernels 2.6 through 4.x, RHEL 6.7 and 7.1, SLES 11 SP4 and 12, FreeBSD 10.2, VMware ESXi 5.5 and 6.0, and UEFI 2.1 through 2.4. Ensure you have Cat5e or better cabling for 2.5G and 5G NBASE-T operation, which is supported in Linux only.

Sustained-load behaviour

The on-chip 10GBASE-T PHYs and 802.3az Energy Efficient Ethernet support help maintain stable throughput during long transfers without excessive heat buildup. Dual independent ports allow load balancing or failover configurations that keep bandwidth available when one link is saturated. Firmware is upgradable to align with evolving IEEE 802.3 standards, preserving performance consistency over the card's service life.

Questions about this item

Does the ST7280-X550AT2 include any cables or brackets in the box?

The card is supplied as the adapter only; Cat5e or Cat6 patch cables and any low-profile bracket must be purchased separately.

When should I choose the dual-port 10GBASE-T model over a single-port version?

Choose this dual-port card when you need two independent 10GbE links for server uplinks, link aggregation or separate storage and client networks.

What throughput can I expect from each RJ45 port once the card is installed in a PCIe 3.0 x8 slot?

Each port negotiates 10Gb/s, 5Gb/s, 2.5Gb/s, 1Gb/s or 100Mb/s; the x8 slot provides enough bandwidth for both ports at full 10Gb/s line rate.
