## Summary description

The InLine 51127E is an internal Ethernet network card with a maximum data transfer rate of 1000 Mbit/s. It connects via PCI Express and is designed for wired connectivity, making it ideal for high-speed network environments.

## Long description

The InLine® Quad Gigabit Network Card (model 51127E) is an internal PCIe network adapter designed for servers and data centers, offering four RJ45 Gigabit ports for stable wired connectivity up to 1 Gbit/s per port. Built on Intel I350AM2 chipset technology and using a PCIe v2.1 x4 interface compatible with x4, x8 and x16 slots, the card supports virtualization features and advanced Ethernet functions for professional network environments.
Advantages
The card delivers four independent Gigabit copper ports for high-throughput network connections and is optimized for energy efficiency and performance with the Intel I350AM2 chipset. PCIe v2.1 (x4) provides sufficient bandwidth for multiple simultaneous streams, while features such as Energy Efficient Ethernet (EEE), DMA coalescing, jumbo frames and extensive offload capabilities reduce CPU load and improve overall throughput. Broad OS support and virtualisation features make it suitable for mixed Windows and Linux environments.
Suitable for
Server and data center network uplinks
Virtualized environments and VMs (device queues, VMDq, up to 8 VMs; up to 32 virtual ports)
iSCSI storage networks and high-throughput applications
Professional wired office and infrastructure connections requiring VLANs and time sync (IEEE 1588 / 802.1AS)
Key specifications
Interface: PCIe v2.1 x4 (compatible with x4, x8, x16 slots)
Ports: 4 × RJ45 (copper), 1 Gbit/s per port
Chipset: Intel I350AM2 ×2
Supported protocols/standards: IPv4, IPv6, IEEE 802.3 / 802.3u / 802.3ab / 802.3x / 802.1Q / IEEE 1588 / 802.1AS
Duplex modes: Half duplex 10/100 Mb/s; Full duplex 10/100/1000 Mb/s
Jumbo frames: up to ~9K
Dimensions: 155 mm × 69 mm (PCIe board)
Operating systems: Windows 11, 10, 8, 7; Windows Server 2008 R2, 2016, 2019, 2021; Linux from kernel 2.6.30
Operating temperature: 0 °C to 55 °C; storage: −40 °C to 70 °C; max humidity: 90 %
How to use
Install the card into an available PCIe x4, x8 or x16 slot on a powered-down system and secure it with the bracket. Connect network cables to the four RJ45 ports using appropriate Cat5e/Cat6 cables for Gigabit operation. Boot the system and install drivers from the supplied CD or download the latest drivers from the manufacturer. Configure IP settings, VLAN (802.1Q) and any virtualization or offload features in the operating system or hypervisor as required.
Usage recommendations
For reliable Gigabit links use Cat5e or better cabling and ensure switch ports support required features (VLAN, jumbo frames, EEE). In virtualized deployments enable supported device queues and RSS/VMDq offloads to distribute network processing and reduce host CPU load. Keep drivers up to date for best compatibility and performance.
