QSW-M408-4C Multi-Gigabit Unmanaged Switch
The QSW-M408-4C is a desktop-style, plug-and-play switch offering eight Gigabit Ethernet ports plus four 10GbE SFP+/RJ45 combo ports, delivering up to 96 Gb/s switching capacity and full NBASE-T support.
Key Features
- 8 × Gigabit Ethernet ports
- 4 × 10GbE SFP+ / RJ45 combo ports
- 96 Gb/s switching capacity
- Desktop form factor
- NBASE-T support (10G / 5G / 2.5G / 1G / 100M)
- Web-based management via QNAP Switch System (QSS)
Flexible Multi-Gigabit Connectivity
The four combo ports let you choose between 10GbE SFP+ fiber or 10GBASE-T/NBASE-T over existing Cat 6/5e/5 cabling.
Direct Attach Copper (DAC) cabling for SFP+ ensures low-latency, high-speed links to servers and storage devices.
Intuitive Web-Based Management
QSS offers a clean web UI with an overview dashboard, step-by-step port setup, and one-click firmware updates.
Administrators can monitor link status, adjust port settings, and maintain network security without extra software.
Layer 2 Switching and Security
Built-in LACP, VLAN, ACL, and LLDP features give IT teams granular control over traffic flows and access policies.
Network segmentation and bandwidth allocation help prevent congestion and enhance data privacy.
Rapid Spanning Tree Protocol (RSTP)
With RSTP support, the QSW-M408-4C delivers loop prevention, redundancy, and fast convergence—ideal for growing small-to-medium networks.
Advanced Flow Control
IEEE 802.3x full-duplex flow control avoids packet loss when traffic surges, ensuring stable throughput even under heavy loads.
Effortless Firmware Updates
QSS lets you update the switch OS with a single click, keeping your network protected against emerging vulnerabilities and bugs.\
Ideal Deployment Scenarios
- High-speed connection for servers, NAS devices, and workstations
- Small offices seeking simple, unmanaged multi-gigabit switching
- Creative studios requiring fast large-file transfers over existing cabling
- Network edge deployments needing RSTP redundancy and basic Layer 2 controls
Optimize Network Performance with bandwidth and packet control
The QSW-M408-4C provides bandwidth and packet control functions (such as LACP, VLAN, QoS, and IGMP Snooping) for boosting network performance through IP grouping and bandwidth management.
| LACP | VLAN | QoS | IGMP Snooping |
|---|---|---|---|
| – Bandwidth allocation – Bandwidth expansion |
– Communication Efficiency – Flexible Segmentation |
– Traffic control – Prioritizing bandwidth |
– Status snooping – Traffic reduction |
Powerful security and system functions
The QSW-M408-4C 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 |
|---|---|---|---|
| – Access controls – Security system |
– Device disclosure – Troubleshooting |
– Loop prevention – Backup path |
– Balance speed – Jam prevention |
Faster speeds using existing cables with 10GBASE-T & NBASE-T
The QSW-M408-4C is compatible with 10GbE and NBASE-T technologies to support up to five speeds (10G / 5G / 2.5G / 1G / 100M). The SFP+/RJ45 (copper) combo ports provide higher transmission speeds with existing cables. Depending on cable types and their lengths, different speeds can be achieved for faster, more efficient data transfer.
Improve team productivity with a 5GbE/ 10GbE High-Speed Network
From NAS with built-in 10GbE SFP+ and 10GBASE-T ports, or NAS with PCIe slots that support 10GbE/5GbE/2.5GbE network adapters, QNAP has led the industry in 10GbE adoption. Other high-speed network solutions from QNAP include Thunderbolt 3 to 10GbE Network Adapters and USB 3.2 Gen 1 to 5GbE Network Adapters. These can all be used with the QSW-M408-4C to create a comprehensive high-speed network environment for boosting the performance of photo/video editing, virtualization, large-file data transfers, and other bandwidth-demanding tasks.
