Dual 2.5GBase-T card for multi-gig networking

The C&N ST7207-2*RJ45 is a dual-port PCIe 3.1 network adapter built on the Intel I226-V controller. It delivers 2.5G, 1G and 100 Mbps speeds over standard RJ45 copper cabling. The low-profile bracket makes it suitable for slim chassis and small-form-factor workstations or servers.

Installation uses a standard x1 slot

The card fits any PCIe x1, x2, x4, x8 or x16 slot running at 5 GT/s. A low-profile bracket is included for narrow cases. Driver support covers Windows 10 and 11, Linux kernels 5.8 and 5.16.18, RHEL 8.1, 8.3 and 8.6, Ubuntu 22.04 LTS, FreeBSD 13.0, VMware ESXi 7.0 and 8.0, plus DPDK, OpenWrt, Unraid and Proxmox VE. The bundled CD driver is outdated; the manufacturer directs users to the Intel download page for the current package.

Sustained throughput at 2.5 Gbps per port

Each port negotiates 2500BASE-T, 1000BASE-T, 100BASE-TX or 10BASE-TE automatically with IEEE 802.3x flow control. The Intel I226-V integrates MAC and PHY on a single die, keeping latency low and CPU utilisation steady during long transfers. Time-sensitive networking features are supported on compatible platforms. The card is not for builders who need fibre uplinks or more than two copper ports.

Questions about this item

How can I confirm the ST7207-2*RJ45 is running at 2.5 Gbps after installation?

Check the link speed in your operating system network settings or switch port LED; a negotiated rate of 2500 Mbps shows the Intel I226-V controller is operating at full 2.5GBase-T speed.

What comes with the card and what must I source separately?

The box contains the dual-port PCIe 3.1 x1 adapter with one full-height bracket fitted and a low-profile bracket included; you supply the Cat5e or better RJ45 cables and a compatible PCIe slot.

Which version of the ST7207 should I choose for a low-profile chassis?

This model includes a low-profile bracket in the package, so the single ST7207-2*RJ45 version fits both standard and slim cases without extra parts.
