The QSW-M3212R-8S4T is a half-width rackmount managed switch with eight 10GbE SFP+ ports and four 10GbE RJ45 ports, providing SMB and SOHO users with additional ports for connecting 10GbE devices with different interfaces at an affordable price. Supporting Layer 2 switching and network management via a user-friendly web user interface, the QSW-M3212R-8S4T offers flexible deployment in high-speed network environments and provides an entry-level network management solution. With a half-width design, the QSW-M3212R-8S4T can be conveniently placed within working environments without taking up too much space, and two can be installed in a single 1U rack space. The QSW-M3212R-8S4T is Made in Taiwan (MIT), providing a high-quality and reliable networking solution.

10G Multi-Gigabit connectivity

Includes eight 10GbE SFP+ fiber ports (backward compatible with 1G SFP) and four 10GbE RJ45 ports (backward compatible with 5G/2.5G/1G) for high-speed networks.

User-friendly management interface

The QNAP Switch System (QSS) is easy to use and provides an overview dashboard, port management and setting guide, making central network management intuitive.

Layer 2 network

Provides Layer 2 management features (such as LACP, VLAN, ACL and LLDP) for IT staff to efficiently control network bandwidth and enhance security.


One of the few web-managed switches that supports Rapid Spanning Tree Protocol (RSTP). Easily and efficiently deploy small/medium-scale networks that support expansion, redundancy, and loop prevention.

Online firmware update

QSS can be updated with just one click, helping IT staff ensure their network security.

Energy saving

Compliant with IEEE 802.3az Energy Efficient Ethernet and IEEE802.3x Flow Control in full-duplex mode, the QSW-M3212R-8S4T avoids packet loss from unparalleled bandwidth and reduces power consumption for low-speed and inactive connections.


Half-width design, two models in 1U

With a half-width rackmount design, a QSW-M3212R-8S4T can be installed in a 1U rack space with another half-width rackmount switch (such as QSW-M2106R-2S2T) for efficient physical space utilization and tidy cabling.

Note: The optional SP-EAR-QSW2FOR1-01 rackmount kit is required if two half-width rackmount switches are installed.

Flexible 12-port 10GbE deployment with eight 10GbE SFP+ and four 10GBASE-T Ethernet

The QSW-M3212R-8S4T provides eight 10GbE SFP+ ports and four 10GbE RJ45 ports for connecting various devices and enabling hybrid high-speed networks. With SFP+ interfaces, Direct Attach Copper (DAC) cables can be used for connecting directly to SFP+ devices. You can also use RJ45 ports to connect 10GBASE-T/NBASE-T™ devices through RJ45 Category 6a (or better) cabling. The switching capacity of the QSW-M3212R-8S4T is 320Gbps , supporting the full potential of each port..



  • 10GbE SFP+ ports are backward compatible with 1GbE SFP.
  • 10GbE RJ45 (copper) ports support up to five speeds (10G/ 5G/2.5G/1G/100M).
  • CAT 6 (or higher) RJ45 cables support Multi-Gig connectivity up to 10GbE.

Dependable performance with effective heat dissipation

With a compact metal body that optimizes cooling performance, the QSW-M3212R-8S4T provides stable and reliable operations even when under full load. The front-panel LEDs also assist in viewing the current system status.

QSS: Human-centered settings guide

The QSW-M3212R-8S4T uses the QNAP Switch System (QSS), featuring an easy-to-use Web GUI with Layer 2 management and value-added functions to simplify network set up and management.

Overview Dashboard

View real-time system information, port connection status and port traffic.

Port Management

View port status, port packet statistics, and configure port speeds.

Setting Guide

Quickly learn how to set up the network using the introduction and step-by-step guide.

Exclusive Status Chart Referencing

Refer to four major status charts during each configuration to avoid going back and forth between different setting pages.

Online Firmware Check and Update

Keep your QNAP switch secure with one-click firmware updates.

Optimize Network Performance with bandwidth and packet control

The QSW-M3212R-8S4T provides bandwidth and packet control functions (such as LACP, VLAN, QoS, and IGMP Snooping) to boost network performance through IP grouping and bandwidth management.

Link Aggregation combines multiple network connections to increase throughput and protect against connection failure. Virtual Networks allows groups of devices from different networks to be combined into a single network. QoS (Quality of Service) prioritizes bandwidth usage to optimize network resource allocation. IGMP snooping assists in minimizing bandwidth loss and preventing network information leakage.

Powerful security and system functions

The QSW-M3212R-8S4T has powerful security and system functions (including ACL, LLDP, RSTP and Flow Control) to help administrators enhance network reliability using access controls, troubleshooting, loop prevention and avoiding packet loss.

ACL LLDP RSTP Flow Control
Filters packets based on rules to offer firewall-like security protection. Allows devices to advertise device information to directly-connected peers/neighbors to simplify troubleshooting processes. Ensures loop-free topology for Ethernet networks by blocking or forwarding traffic. Balances traffic between a sender and a receiver to avoid network congestion.
