Internal Ethernet Network Card InLine 51127B 1000 Mbit/s PCI Express

Four RJ45 Gigabit portsfor a stable and fast network connection
PCIe x1 interfacefor high compatibility with various systems
Supports VLAN (802.1Q), jumbo frames (up to 9K) and flow control
Suitable for servers, workstations and AV applications
Includes low-profile slot bracketfor easy integration into compact housings

The InLine® Quad Gigabit network cardis a powerful solution for expanding your system with four Gigabit Ethernet ports. It is ideal for servers, workstationsand professional AV applicationsand supports modern network technologies for maximum efficiency.
With a data rate of up to 1 Gb/sper port, the card enables a stable network connection with auto-negotiationand supports Wake-on-LAN (WOL), VLANs (802.1Q) and jumbo frames (up to 9K). The Realtek RTL8111F chipset used ensures reliable performance and energy efficiency.
Thanks to the PCIe x1 interface, the network card is compatible with a wide range of systems and enables efficient data transmission. The supplied low-profile slot bracketfacilitates installation in compact housings.

How to use

Install the card into an available PCIe x1 slot on the motherboard and secure it with the standard or low-profile bracket according to the case type. Connect network cables to the RJ45 ports and ensure proper cabling category for the required speed. Install drivers from the supplied CD or download the latest drivers from the manufacturer if necessary. Configure network settings in the operating system, enable VLANs or jumbo frames where required, and activate Wake-on-LAN in BIOS and OS if needed.

Recommendations

Use appropriate Ethernet cables (Cat5e or higher for Gigabit) and keep firmware/drivers up to date. Ensure the host system provides sufficient cooling and that BIOS settings allow PCIe device operation and Wake-on-LAN if used.
