QNAP Quad-Port 2.5GbE PCIe Network Expansion Card

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.
• Includes both full-height and low-profile brackets for flexible installation in various chassis sizes.
• Compatible with Windows, Linux, and QNAP’s QTS or QuTS hero operating systems for versatile deployment.
