Overview The QNAP QGD-1602-C3758-16G-US is a managed network switch that combines sixteen Power over Ethernet (PoE) ports with an integrated NAS enclosure and robust processing power. Designed to consolidate networking, storage, and application hosting into a single chassis, it helps reduce rack space, power consumption, and cabling complexity. Powered by an Intel Atom C3758 8-core 2.2 GHz processor and equipped with 16 GB of DDR4 memory, this unit supports up to six virtual machines, making it suitable for tasks like network video recording and firewall services. Its front panel features eight 2.5 GbE ports and eight 1 GbE ports, with four 2.5 GbE ports delivering up to 90 W each and the remaining twelve ports providing 30 W each, totaling a 370 W PoE budget. This setup can power high-demand devices such as Wi-Fi 6 access points, PTZ cameras, VoIP phones, and digital signage without additional power injectors. Key features Sixteen PoE ports with a combined 370 W budget, including four ports capable of supplying up to 90 W each, enabling support for high-power devices directly through the switch. Mixed-speed Ethernet ports with eight 2.5 GbE and eight 1 GbE connections, allowing seamless integration of both modern and legacy network devices. Two 10 GbE SFP+ uplink ports provide high-speed connectivity to servers or core network infrastructure, ensuring efficient data flow. Integrated NAS enclosure with two 2.5-inch SATA drive bays and two M.2 NVMe SSD slots, offering flexible storage options for caching and high-capacity data storage. Intel Atom C3758 processor paired with 16 GB DDR4 memory supports running up to six virtual machines, enabling versatile application hosting on the same device. High switching capacity of 96 Gb/s and nonblocking throughput of 48 Gb/s maintain smooth network traffic even under heavy loads. Two PCIe Gen3 x4 slots allow for future expansion with additional network or storage cards, extending the device’s capabilities as needs evolve. Layer 2 management features including VLAN, Quality of Service (QoS), and link aggregation provide advanced network control and traffic optimization. Key specs Processor: Intel Atom C3758 8-core 2.2 GHz Memory: 16 GB DDR4 PoE ports: 16 (four ports up to 90 W, twelve ports up to 30 W) PoE budget: 370 W total Ethernet ports: 8 x 2.5 GbE, 8 x 1 GbE Uplink ports: 2 x 10 GbE SFP+ Storage bays: 2 x 2.5-inch SATA, 2 x M.2 NVMe SSD slots Switching capacity: 96 Gb/s Nonblocking throughput: 48 Gb/s Expansion slots: 2 x PCIe Gen3 x4 Connectivity and compatibility This switch supports a wide range of network devices through its combination of 2.5 GbE and 1 GbE ports, making it compatible with both newer and older equipment. The two 10 GbE SFP+ uplinks enable fast connections to servers or core switches, which is essential for maintaining high performance in busy network environments. The PoE capabilities allow powering devices such as Wi-Fi 6 access points, PTZ cameras, and VoIP phones directly from the switch, reducing the need for separate power supplies and simplifying installation. Performance and reliability The Intel Atom C3758 processor and 16 GB of DDR4 memory provide ample resources to run multiple virtual machines, which can handle tasks like network video recording, firewall management, or lightweight file serving. The high switching capacity and nonblocking throughput ensure that network traffic flows without bottlenecks, even when multiple high-bandwidth devices are connected. The inclusion of PCIe expansion slots offers future-proofing by allowing additional network or storage cards to be added as requirements grow. Ideal uses and environments This device is well suited to small and medium businesses, branch offices, and retail locations that require a compact solution combining network switching, PoE power delivery, and local storage. It is particularly effective in setups where space and power efficiency are priorities, and where managing multiple devices such as surveillance cameras, wireless access points, and VoIP phones is necessary. The ability to host virtual machines on the same hardware simplifies deployment and ongoing management, making it a strong choice for IT teams looking to streamline infrastructure.
