InLine 51127F network card Internal Ethernet 1000 Mbit/s

Reliable Gigabit connection: Ensures stable network speeds of up to 1 Gbps via an RJ45 port.
Flexible use: PCIe x1 interface with low-profile bracket for full compatibility with standard and compact cases.
Advanced features for professionals: Supports jumbo frames, VLAN tagging (IEEE 802.1Q), auto MDI-X, and flow control for efficient data transfer.
Wake-on-LAN support: Allows remote power-up of systems—ideal for server or remote environments.
Broad operating system compatibility: Can be used with Windows 7 to 11, Windows Server 2008 R2 and later, and Linux 2.6.30 and later.

The InLine® Gigabit network card with Realtek RTL8111F chipset is the ideal solution for retrofitting or expanding network functions in desktop systems, workstations, or servers. The PCIe x1 interface allows quick and easy integration into existing systems—even in low-profile cases thanks to the included slot bracket.
With a transfer rate of up to 1 Gb/s and comprehensive support for auto-negotiation and auto MDI/MDI-X, the network card ensures maximum compatibility with existing network environments. VLAN tagging according to IEEE 802.1Q, jumbo frames up to 9K, and flow control according to IEEE 802.3x offer professional features for demanding use in corporate networks or home servers.
Additional energy-saving features such as link-down power saving and power-down mode make the card particularly efficient in continuous operation. Wake-on-LAN enables remote power-up of compatible systems—a plus for IT administrators and power users.
Thanks to broad driver support, the card runs on current versions of Windows and Linux from kernel 2.6.30 onwards. Two status LEDs on the RJ45 port indicate connection and data activity—for quick diagnosis directly on the device.
Whether as a replacement for a defective network interface or to expand existing systems, this network card is a powerful and cost-effective choice for private and professional applications.

How to use

Install the card into an available PCIe x1 slot (or larger PCIe slot) on the motherboard. Fit the included low-profile bracket if installing in a compact case. Connect a suitable Cat.5e or higher Ethernet cable to the RJ45 port. Install drivers from the provided CD or obtain current drivers from the chipset or manufacturer website. Configure network settings in the operating system and enable Wake-on-LAN in BIOS/UEFI and OS if remote power-up is required.

Recommendations

For stable Gigabit performance, use Cat.5e or Cat.6 cables and ensure switch or router ports support 1 Gb/s. Enable appropriate drivers and firmware updates for best compatibility; activate Wake-on-LAN and power-saving features only if supported by the system BIOS/UEFI and network configuration.
