  • Speed10Gbps
  • Connectors2 x RJ45
  • InterfacePCI-Express 3.0
  • 10 Gbps throughput for high-bandwidth workloads
  • Two RJ45 ports connect directly to copper cabling
  • PCI Express 3.0 x8 interface fits modern servers
  • OCP 3.0 form factor simplifies rack deployment
  • Intel controller delivers reliable packet processing

Dual-port 10 GbE adapter

This Intel X557T2OCPG1P5 network card adds two RJ45 ports running at 10 Gbps over twisted-pair copper. It installs in a PCI Express 3.0 slot and targets servers or workstations that need high-throughput wired links without fibre cabling. The OCP form factor suits compatible chassis and rackmount systems.

Suits copper-based 10 GbE deployments

Teams upgrading existing Cat6a or Cat7 runs will use the twin RJ45 ports directly. Sites that require fibre SFP+ transceivers or single-port density should select a different adapter. Environments limited to PCI Express 2.0 bandwidth may not reach full line rate on both ports.

PCI Express 3.0 x8 electrical interface

The card operates on a PCI Express 3.0 connection, which determines the maximum host bandwidth available to the two 10 Gbps ports. Verify that your motherboard or riser provides at least an x8 electrical link to avoid bottlenecks.

Questions about this item

What free PCI-Express 3.0 slot width does the X557T2OCPG1P5 need on the motherboard?

The card installs in any available PCI-Express 3.0 slot, typically x4 or wider, and draws power directly from that slot.

Will the two RJ45 ports on this card link at 1Gbps with my existing Cat5e patch cables?

Each 10Gbps port auto-negotiates down to 1Gbps, so standard Cat5e cables and older switches will establish a working link.

Which LED pattern on the bracket confirms both 10Gbps ports have negotiated full speed after driver installation?

Solid amber LEDs on each RJ45 port indicate a 10Gbps link; blinking amber shows activity at that speed.
