## Summary description

InLine 51125B is a network interface adapter designed to provide network connectivity for compatible systems. As a card-format interface (PCI/PCIe), it integrates into desktop or server motherboards to add or replace network ports. It is suitable for expanding wired network capability, upgrading legacy systems, or adding an additional network interface for routing, monitoring, or virtualization tasks.

## Long description

The InLine Dual Gigabit Network Card (model 51125B) is a PCI Express x4 network interface adapter with two RJ45 ports providing wired connectivity at 10/100/1000 Mb/s per port. Built around the Intel 82576EB controller, the card supports VLAN, jumbo frames up to 9.5K, IPv4/IPv6, and features designed to reduce CPU load and increase throughput, such as receive-side scaling (RSS) and checksum offload. The package includes a low-profile slot bracket for installation in standard and compact cases, a driver CD and a manual.
Advantages
The adapter delivers up to 1 Gb/s per port via two Gigabit Ethernet interfaces and uses a PCIe v2.0 x4 connection to provide sufficient bandwidth. Intel 82576EB-based design ensures stable connections and advanced protocol support, while RSS, flow control and checksum offload reduce system CPU load. VMDq support enables efficient resource allocation for virtualized environments, and LED indicators per port give clear link and activity status.
Suitable for
Adding or upgrading wired network ports on desktops and servers
Virtualized environments requiring network resource partitioning for up to eight VMs
Small office or home networks needing reliable gigabit connections

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.
Usage 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.
