QNAP QXG-2G1T-I225 network card Internal Ethernet 2500 Mbit/s

The QNAP QXG-2G1T-I225 is an internal 2.5 GbE network expansion card that provides wired Ethernet connectivity with a maximum data transfer rate of 2500 Mbit/s. It uses a PCI Express host interface and a standard Ethernet port to upgrade desktops, workstations, or network appliances for faster local network transfers while remaining compatible with existing cabling.

Advantages

This network card delivers up to 2.5 Gbps throughput over a single RJ-45 port, supports low-latency wired connections, and installs into a PCI Express slot for internal deployment. It adheres to relevant networking standards (IEEE 802.1Qav, 802.1Qbv, 802.1as) to help with traffic management and synchronization, and is suitable for boosting wired network performance without requiring new cabling.

Suitable for

• Upgrading desktop or workstation network interfaces to 2.5 GbE
• Improving NAS or server connectivity in home and small office environments
• High-bandwidth local file transfers, backups, and media streaming

How to use

Power down the PC or server and open the chassis to access an available PCI Express slot. Insert the QXG-2G1T-I225 into the slot and secure it with the bracket screw. Close the chassis and connect an Ethernet cable to the RJ-45 port. After booting the system, install any required drivers or firmware provided by QNAP or your operating system, then configure network settings (IP address, speed/duplex if needed) through the OS network control panel or management interface.

Recommendations

For best results use Category 5e or better cabling and configure switch ports to support 2.5G/Auto-Negotiation. Ensure drivers and firmware are kept up to date and install the card in a full-length PCIe slot that meets the host interface requirements.
