QNAP QXG-2G1T-I225 2.5GbE Network Expansion Card
Single-port 2.5GbE PCIe adapter based on Intel Ethernet silicon. Record applies to the exact SKU named here; verify the physical label and revision.
IDENTIFICATION: Product label: QXG-2G1T-I225. Link rates are nominal negotiated signaling rates, not measured throughput.
Specifications and OS compatibility
| Catalog subcategory | Ethernet adapters |
|---|---|
| Exact product SKU | QXG-2G1T-I225 |
| Controller | Intel Ethernet Controller I225-LM. |
| Bus, lane and port interface | PCI Express Gen 2.0 x1; one RJ-45 copper port. |
| Ports and media | 1 port(s); 2.5GBASE-T interface. |
| Nominal line rate (not measured) | 2.5, 1 Gb/s, 100 Mb/s and 10 Mb/s nominal negotiated link rates. |
| Operating systems and drivers | QNAP lists supported QTS/QuTS hero, Windows and Linux configurations; Windows Server and Linux kernel support require a matching Intel/QNAP driver. Check current QNAP downloads and NAS compatibility. |
| Compatibility notes | Fits PCIe x1 electrical slots. The peer and cable must support 2.5GBASE-T for 2.5 Gb/s; Cat 5e or better is specified by QNAP. Confirm OS and host/NAS qualification before purchase or deployment. |
| Measured throughput | No physical specimen benchmark is claimed. A meaningful result must identify host, peer, link partner, media, driver/firmware, traffic pattern, test tool and duration. |
Model and revision notes
Fits PCIe x1 electrical slots. The peer and cable must support 2.5GBASE-T for 2.5 Gb/s; Cat 5e or better is specified by QNAP. Confirm OS and host/NAS qualification before purchase or deployment.
Confirm exact card revision, device ID, transceiver/cable type, host firmware, bracket and driver build before installation. Use vendor qualification data for server/NAS deployment.
Preservation and measurement notes
Record card revision, controller marking and driver/firmware versions. Power down before installation; handle by edges and store in ESD shielding.
No measured throughput is represented by the nominal line rate. Record peer, media, negotiated rate, traffic pattern, test tool and duration for any future benchmark.
