InLine 51125B network card Internal Ethernet 1000 Mbit/s

Maximum network performance:Two RJ45 Gigabit ports provide reliable data transfer at up to 1 Gb/s each for demanding applications.
Optimized for virtualization:Supports Intel VMDq for efficient allocation of network resources to up to eight virtual machines.
Efficient system load reduction:Features such as RSS, flow control, and checksum offload reduce CPU load and improve overall performance.
Reliable data connection:The Intel 82576EB controller ensures stable connections with VLAN, jumbo frames, and IPv6 support.
Flexible use:Includes low-profile slot bracket for standard and compact cases and supports PCIe x4 according to v2.0 standard.

The InLine® Dual Gigabit Network Card with two RJ45 ports is the ideal solution for anyone who needs maximum stability and performance in their network. Equipped with the Intel 82576EB controller, the card offers extensive functions for increasing efficiency and reducing system load, including VLAN support, jumbo frames, flow control, and receive side scaling (RSS).
Thanks to its support for VMDq, the card is perfectly suited for virtualized environments and allows network resources to be allocated to up to eight virtual machines. The PCI Express x4 interface according to v2.0 provides sufficient bandwidth for both ports and ensures uninterrupted data transmission.
The included low-profile slot bracket allows the card to be flexibly integrated into a wide variety of systems, from compact office PCs to rack servers. The high-quality workmanship and extensive compatibility with IPv4 and IPv6 make the card a future-proof choice for professional network infrastructures and ambitious home networks.

How to use

Install the card into an available PCIe x4 (or larger) slot on the motherboard and secure it with the appropriate bracket (standard or included low-profile). Connect network cables to the RJ45 ports and verify link/activity LEDs for status. Install drivers from the provided CD or download the latest drivers from the manufacturer's website, then configure network settings, VLANs or virtualization offload features in the operating system or hypervisor.

Recommendations

For reliable gigabit performance use Cat.5e or higher cabling and ensure the host system has a free PCIe x4 or x8 slot. In virtualized setups enable VMDq and RSS in the hypervisor or guest configuration to balance network load across CPUs and virtual machines.
