SMUGDESK dual-port 10GBASE-T PCIe card with passive heatsink and two RJ45 ports

SMUGDESK

SMUGDESK ST7280-X550AT2 Dual Port 10GBASE-T PCIe 3.0 x8 Network Card

SKU CH-G3Z5-THRNV

Dual-port 10GBASE-T copper NIC upgrades existing Cat5e or Cat6a to 10/5/2.5/1 Gbps with Intel X550AT2, PCIe 3.0 x8, virtualization offloads, jumbo frames, VLAN, PTP 1588 and full/low-profile brackets

  • Dual 10 GbE ports auto-negotiate 10/5/2.5/1 Gbps over copper cabling
  • PCIe 3.0 x8 interface fits x4 and x16 slots with both brackets included
  • Intel X550AT2 chip offloads TCP/UDP, VXLAN, RSS and virtualization queues to cut CPU load
  • iSCSI and FCoE boot plus 9 KB jumbo frames and IEEE 1588 clock sync for storage clusters
  • Driver support spans Windows, Linux, VMware ESXi and FreeBSD for broad OS coverage

Dual 10GBASE-T ports with NBASE-T auto-negotiation

The SMUGDESK ST7280-X550AT2 adds two independent RJ45 ports that auto-negotiate 10G, 5G, 2.5G, 1G and 100Mbps speeds. It connects to PCIe 3.0 x8 slots and works in x4 or x16 slots as well. Full-height and low-profile brackets are supplied for rack servers or compact chassis. The card targets DIY NAS builders, virtualization hosts and businesses upgrading copper networks without fibre rewiring. Buyers who need fibre SFP+ connectivity or single-port 10G will not be served by this model.

Passive heatsink for silent 24/7 operation

A passive heatsink dissipates heat without fans, keeping the adapter stable during continuous workloads. The Intel X550AT2 controller handles 10G over Cat6a and 5G or 2.5G over existing Cat5e cabling. PCIe 3.0 x8 electrical interface provides sufficient bandwidth for dual-port line-rate traffic. Power draw and acoustic profile remain minimal because no active cooling is present. Installers who require active airflow direction or fan-speed monitoring will not find those controls here.

Virtualization offloads and broad OS driver support

SR-IOV, VMDq, RSS, TCP/UDP checksum offload and VXLAN tunnel offload reduce host CPU utilisation during high-speed transfers. iSCSI and FCoE boot, 9KB jumbo frames, 802.1Q VLAN tagging and IEEE 1588 precision time protocol assist clustered storage and synchronised workloads. Drivers are provided for Windows desktop and Server, Ubuntu, CentOS, RHEL, SLES, VMware ESXi and FreeBSD. Users needing proprietary management suites or hardware-accelerated encryption offloads not listed above will not gain them from this card.

Questions about this item

How do I install the ST7280-X550AT2 in a low-profile chassis and which bracket do I use?

The card ships with both full-height and low-profile brackets; swap to the low-profile bracket before inserting it into a PCIe 3.0 x8, x4 or x16 slot.

What maintenance does the passive heatsink need for 24/7 operation?

The passive heatsink has no moving parts; keep the chassis airflow clear and remove dust periodically so the X550AT2 stays within thermal limits.

What throughput limit appears first when both 10G ports run sustained traffic?

The PCIe 3.0 x8 host interface caps combined throughput at the bus maximum, so aggregate speed cannot exceed the slot bandwidth.
