QNAP QSW-M3212R-8S4T 12-Port 10G RJ45/SFP Managed Network Switch

The QNAP QSW-M3212R-8S4T-US is a managed 12-port network switch that delivers 10 Gigabit Ethernet performance to servers, storage, and high-end workstations. Eight SFP+ ports support fiber connections for longer cable runs or electrically noisy areas, while four RJ45 ports handle copper links for deskside or rack-adjacent devices. Together these ports give you the flexibility to design a network that matches each location and budget without compromising speed.

A switching capacity of 240 Gb/s and a non-blocking throughput of 120 Gb/s keep traffic moving at line rate, so large backups, media files, and virtual machine images travel without bottlenecks. The chassis is made of metal and uses a half-width layout, allowing two units to sit side by side in a single rack unit. Dual cooling fans pull heat away from the components and help maintain reliable 24-hour operation in equipment rooms or server closets.

Layer 2 features such as VLAN segmentation, Link Aggregation Control Protocol, access control lists, and Link Layer Discovery Protocol give administrators the tools they need to organize traffic, increase bandwidth, and secure critical resources. Rapid Spanning Tree Protocol adds redundancy, ensuring that a link failure does not take the network down. All settings are available through a web based interface that can be reached from any standard browser, making day-to-day management straightforward even for smaller IT teams.

Support for 9 K jumbo frames improves transfer efficiency when moving large media projects to and from a QNAP NAS or other high-throughput storage. With an internal power supply that draws up to 80 W and international certifications that include CE, FCC, VCCI, and BSMI, the switch is ready for deployment in offices, creative studios, campus labs, or branch sites that need scalable 10 Gb connectivity.
