10G RJ45 Network Card Intel X550

This C&N ST7381 network card adds a single 10GBASE-T RJ45 port to a PC or server through a PCIe 3.0 x4 slot. The Intel X550 controller auto-negotiates speeds from 100Mb up to 10Gb. It targets administrators who need 10Gb copper connectivity on Windows Server, Linux or ESXi hosts without fibre cabling.

Installation Brackets and Driver Source

A 12cm standard bracket is fitted and an 8cm low-profile bracket is included for slim chassis. The card fits any PCIe 3.0 x4, 2.0 or 1.1 slot with four lanes. Drivers must be downloaded from the Intel website or requested from the supplier; no media is bundled. Mac OS is not supported.

Cable Distance and Protocol Limits

10GBASE-T reaches 55m over Category 6 cable and 100m over Category 6A. The PCIe 3.0 x4 interface provides 8.0GT/s per lane, capping theoretical throughput at the bus level. Features such as SR-IOV, VMDq, MACsec IEEE 802.1 AE and IEEE 1588 PTP are handled by the X550 controller within those bandwidth and distance constraints.

이 상품에 대한 질문

How do I confirm the ST7381 is linked at 10 Gbps after installing it?

Check the adapter properties in Windows Device Manager or run ethtool in Linux; the link speed should read 10 Gbps when connected with Category 6A cable up to 100 m or Category 6 up to 55 m.

What brackets are included with the ST7381 and do I need to buy a cable separately?

The card ships with a pre-installed 12 cm regular-profile bracket and an 8 cm low-profile bracket in the box; an RJ45 Category 6 or 6A cable is not included and must be purchased separately.

Which ST7381 variant should I choose for a PCIe 3.0 x4 slot on Windows Server 2022?

The ST7381 is a single model using the Intel X550 controller on a PCIe 3.0 x4 interface and supports Windows Server 2022 along with Windows 11, 10, Linux and FreeBSD; no other versions or capacities are offered.
