QNAP QSW-M2108-2S network switch Managed L2 2.5G Ethernet (100/1000/2500) Grey

The QSW-M2108-2S is a Layer 2 web-managed switch with two 10GbE SFP+ ports and eight 2.5GbE RJ‑45 ports, offering an 80 Gbit/s switching capacity. It supports common IEEE networking standards and provides a compact desktop form factor with a 12V DC input. Designed for hybrid high-speed network environments, the switch delivers entry-level network management through a user-friendly web GUI (QSS) and is suitable for environments that need cost-effective upgrades to 2.5GbE or 10GbE connectivity.

Advantages

The QSW-M2108-2S combines high port density with multiple 10GbE SFP+ uplinks and eight multi-speed 2.5GbE ports, enabling flexible connectivity to both copper and fiber equipment. It offers an intuitive QNAP Switch System (QSS) web interface for simplified Layer 2 management, plus support for LACP, VLAN, QoS and IGMP Snooping to optimize bandwidth and traffic. Security and stability features such as ACL, LLDP, RSTP and Flow Control help maintain reliable operation, while the compact desktop design and clearly labeled ports enable easy deployment and plug-and-play use.

Suitable for

• Small offices and home offices upgrading to multi-gigabit networking
• Workgroups requiring mixed 2.5GbE and 10GbE connectivity
• Edge deployments or server closets with limited space

How to use

Place the QSW-M2108-2S on a stable surface and connect the 12V DC power adapter. Use SFP+ DAC or fiber modules in the SFP+ slots for 10GbE uplinks and connect devices to the RJ‑45 ports with Cat5e/6/6a/7 cabling depending on required speeds (Cat6 or better recommended for 10GBASE‑T/NBASE‑T). Access the QSS web GUI from a browser by connecting a management PC to the switch or the same network, then follow the on-screen guide to configure ports, VLANs, LACP and QoS according to your network plan. For basic setups the switch is plug-and-play and will forward traffic without additional configuration.

Recommendations

For reliable 10GBASE‑T performance use Cat6A or better cabling and short, high-quality DAC or fiber links for SFP+ connections. Configure VLANs and QoS to prioritize latency-sensitive traffic and enable RSTP to prevent loops in mixed-layer networks.
