Single-port 2.5 GbE expansion card

The Qnap QXG-2G1T-I225 adds one 2.5 GbE RJ45 port via a PCIe Gen2 x1 slot. It uses the Intel Ethernet Controller I225-LM and supports link speeds of 2.5 Gbps, 1 Gbps, 100 Mbps and 10 Mbps. The card is designed for QNAP NAS units running QTS 4.4.2 or later and also works with Windows 10 1809 or later, Linux kernel 4.20 or 5.x, and Windows Server 2019 with a driver.

Suits NAS owners needing one faster link

This card fits users who want to upgrade a single network connection to 2.5 GbE on a compatible QNAP system or a PC with a free PCIe x1 slot. It is not for buyers who need multiple ports, 10 GbE or fibre connectivity, or who cannot install a low-profile PCIe card in their chassis.

PCIe Gen2 x1 interface

The card plugs into any PCIe Gen2 x1 or larger slot, providing the electrical connection for the single 2.5 GbE port. This slot requirement determines whether the card can be installed in your specific NAS model or motherboard.

Questions about this item

Should I pick this single-port 2.5 GbE card or a dual-port model?

Choose this card when you only need one 2.5 GbE link for a workstation or NAS upgrade; add a dual-port model only if you require two independent connections.

What does the 2.5 GbE rating deliver in daily use?

It lets you move large files or backups at up to 2.5 Gbps over existing Cat5e cabling, provided the switch and storage can sustain that rate.

How does the PCIe Gen2 x1 slot limit the card?

The Gen2 x1 link caps theoretical throughput at the lane's maximum, so the 2.5 GbE line rate remains the practical ceiling.
