Product information

Description

The InLine® Quad Gigabit network card adds four RJ45 Gigabit Ethernet ports to systems via a PCIe x1 interface, offering stable 1 Gb/s connections per port for servers, workstations and AV applications. It supports VLAN (802.1Q), jumbo frames up to 9K, Wake-on-LAN and flow control. The card uses the Realtek RTL8111F chipset with ASM1184e and includes a low-profile slot bracket for installation in compact housings.

Advantages

Provides four independent Gigabit Ethernet ports for increased network connectivity. Compatible with a wide range of systems through the PCIe x1 (PCIe v1.1) interface. Supports modern network features such as VLAN tagging (802.1Q), jumbo frames (up to 9K), Wake-on-LAN and flow control for reliable and efficient operation. Low-profile bracket included for easy integration into small form-factor cases.

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.
