Product information

Description

The InLine Dual Gigabit PCIe Network Interface Card 2x RJ45 1Gb/s Realtek RTL8111 is an internal dual-port wired networking solution designed to expand connectivity in desktop computers and servers. Featuring a PCI Express host interface and a reliable Realtek RTL8111 chipset, this network adapter is equipped with two RJ45 Ethernet ports supporting transfer speeds up to 1Gb/s per port. It adheres to established networking standards including IEEE 802.3ab and IEEE 802.3u, providing robust and stable high-speed network integration for professional, workstation, and office environments.

Advantages

This network interface card offers dual Gigabit Ethernet connectivity, enabling parallel connections for enhanced network flexibility and redundancy. Its PCI Express host interface ensures a secure and high-bandwidth connection to the motherboard. Support for advanced standards such as IEEE 802.3az ensures energy-efficient data transmission, reducing power consumption during operation. The inclusion of a low-profile slot bracket allows the card to fit into both standard desktop towers and compact server housings seamlessly.

Suitable for

  • Expanding wired network connectivity in desktop computers and servers
  • Setting up dual network connections for redundancy or load balancing
  • Integrating into standard and compact computer chassis using the included low-profile bracket
  • Deploying in systems running various versions of Windows and Linux operating systems

When it may not be suitable

This network card is not compatible with wireless networks, as it is strictly designed for wired Ethernet connectivity using RJ45 cables. It also cannot be installed in systems that lack an available PCI Express expansion slot or systems requiring speeds exceeding 1Gb/s per port, such as 10G networks.

Key specifications

  • Wired connectivity technology with Ethernet interface
  • PCI Express host interface
  • Two RJ45 Ethernet ports
  • Supports up to 1Gb/s data transfer speeds
  • Networking standards: IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, IEEE 802.3az, IEEE 802.1Q, IEEE 802.3x
  • Realtek RTL8111 chipset

How to use

Power down your computer, unplug it from the electrical outlet, and open the system case. Insert the network interface card firmly into an available PCI Express slot on the motherboard and secure the bracket to the chassis. Close the case, reconnect the power, and boot up the system. Install the appropriate drivers for your specific operating system version to enable full functionality of both RJ45 ports before connecting your Ethernet cables.

What to consider before purchase

  • Verify that your computer motherboard has an available PCI Express slot
  • Check operating system compatibility with your current Windows or Linux version
  • Ensure your local network infrastructure supports Gigabit speeds to utilize the card fully

Usage recommendations

For optimal stability and network performance, always install the latest manufacturer-approved drivers and use certified Cat5e or Cat6 Ethernet cables for connections up to 1Gb/s.
