QNAP QXG-2G4T-I225

Overview

The QNAP QXG-2G4T-I225 is a PCIe network expansion card designed to add four 2.5Gb Ethernet ports to desktops, servers, or QNAP NAS devices. It significantly boosts network speeds up to 2.5 times faster than standard Gigabit connections, making it ideal for transferring large files, migrating virtual machines, and streaming high-resolution media with reduced wait times. The card fits into a PCIe 2.0 x4 slot and supports automatic speed adjustment to 1Gb, 100Mb, or 10Mb when connected to older network equipment.

Key features

• Four 2.5Gb Ethernet ports provide faster data transfer without needing a full cabling overhaul.
• Automatic backward compatibility ensures seamless connection with existing 1Gb, 100Mb, and 10Mb networks.
• Port teaming allows combining multiple ports for increased bandwidth or failover protection.
• Supports VLAN segmentation to organize and secure network traffic efficiently.
• Enables jumbo frames and Time Sensitive Networking to enhance performance for latency-sensitive applications.
• Remote management features like PXE boot, Wake-On-LAN, and Intel AMT simplify setup and maintenance.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
