Dual-port Gigabit server adapter

The 10Gtek 82576-2T-X1 is a dual-port Gigabit Ethernet network card built around the Intel 82576 controller. It targets servers and workstations that need two copper connections on a single PCI Express 2.0 x1 slot. Compatible operating systems include Windows Server 2003 through 2019, Windows XP through 10, Linux distributions, and VMware ESXi 5 and 6.

Low-profile bracket included

Installation uses a standard or low-profile bracket, both supplied, allowing the card to fit in small-form-factor cases or standard servers. The PCIe 2.0 x1 interface limits bandwidth to 2.5 GT/s, so the two ports share a single lane. Drivers are included on media and are also available from the Intel website; hot-swap capability is not supported.

Two RJ45 ports up to 100m

Each RJ45 port handles 10, 100, or 1000 Mbps over Category 5 or better cabling at distances up to 100 metres. Jumbo frames up to 9.5 KB are supported for improved throughput on large transfers. The single PCIe x1 lane becomes the bottleneck when both ports run at full line rate simultaneously. VMware ESXi 7.0 and newer are not supported.

Questions about this item

How do I verify the Intel 82576 controller is active and both RJ45 ports are linked at 1000Mbps after installation?

Check Device Manager or lspci to confirm the Intel 82576 appears without errors, then ensure each port shows a 1000Mbps full-duplex link light and passes a ping test to another host.

What ships with the card and what must I source separately for a low-profile server build?

The box contains the 82576-2T-X1 dual-port card and a low-profile bracket; you must supply Cat5 or better Ethernet cables and a PCIe 2.0 x1 slot in the server.

Which 10Gtek model should I choose if I need dual copper ports with SR-IOV and jumbo frames up to 9.5KB on a PCIe x1 slot?

The 82576-2T-X1 provides two RJ45 ports, SR-IOV support and 9.5KB jumbo frames on a PCIe 2.0 x1 interface, unlike the single-port or quad-port alternatives listed.
