Network Card InLine 51128K Dual Gigabit 2x RJ45 PCIe x1

The InLine 51128K Dual Gigabit network card is a PCIe x1 adapter that adds two RJ45 Gigabit Ethernet ports to desktop or server systems. It enables wired connections up to 1 Gbps per port and is intended for systems with a free PCIe x1 slot. The card supports standard Ethernet features for reliable LAN access, providing an easy hardware option to expand network capacity, increase redundancy, or separate traffic for virtualization and small office deployments.

Advantages

This dual-port PCIe network card offers two independent Gigabit Ethernet interfaces on a compact x1 form factor, allowing high-speed wired connections without occupying a large slot. The card supports full-duplex operation at 10/100/1000 Mbps, enabling stable throughput for client, server, or virtualization workloads. Its straightforward PCIe interface ensures broad compatibility with common desktop and server motherboards that provide a PCIe x1 slot.

Key specifications

How to use

Install the card into an available PCIe x1 slot on a powered-off system, secure it with the bracket screw, and connect standard Ethernet cables to the RJ45 ports. After power-up, the operating system should recognize the adapter and install appropriate drivers automatically or prompt for driver installation if required. Configure network settings in the OS or network management software to set IP addresses, enable link aggregation or VLANs, and adjust speed or duplex settings as needed.

Recommendations

The card is best used with Cat5e or Cat6 cabling to achieve reliable Gigabit performance; ensure the host system BIOS and OS support PCIe x1 devices and check for updated network drivers from the system vendor when deploying in server environments.
