QNAP QGD-1602-C3558-8G-US

Overview

The QNAP QGD-1602-C3558-8G-US is a 16-port managed network switch that combines multi-gigabit Power over Ethernet (PoE++) capabilities with an integrated NAS enclosure and virtualization features. Powered by a 2.2 GHz Intel Atom C3558 quad-core processor and equipped with 8GB of DDR4 RAM, this device supports high-speed networking alongside centralized storage. It offers sixteen ports split between eight 2.5G and eight 1G connections, all delivering up to 200W total PoE power, making it suitable for powering IP cameras, access points, and VoIP phones without additional power adapters.

With two 10G SFP+ uplink slots, the switch integrates easily into fiber networks or faster backbone infrastructures. Storage options include two 2.5-inch SATA bays and dual M.2 NVMe SSD slots for cache acceleration, enhancing storage responsiveness. Running on QNAP’s QTS operating system, it provides Layer 2 switching features such as VLAN, QoS, and IGMP snooping, along with virtualization support for running virtual machines and containers. This combination makes it a practical and space-saving solution for small to medium-sized businesses requiring both network management and flexible computing resources.

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.
