User-friendly management interface
Featuring a user-friendly web UI, the QNAP Switch System (QSS) provides an overview dashboard, port management and setting guide, making central network management intuitive and easy.
Layer 2 network
The QSW-M408-2C provides Layer 2 management features, such as LACP, VLAN, ACL and LLDP for IT administrators to efficiently control the network bandwidth and enhance security.
RSTP protocol
The QSW-M408-2C is one the few web-managed switches that supports Rapid Spanning Tree Protocol (RSTP). You can easily and efficiently deploy small/medium-scale networks that support expansion, redundancy and loop prevention.
Flow Control
Compliant with IEEE802.3x Flow Control in full-duplex mode, the QSW-M408-2C avoids packet loss from unparalleled bandwidth.
Online OS update
QSS (QNAP Switch System) helps administrators update firmware with just one click, ensuring network security.
Flexible deployment with multiple 10G SFP+ fiber and Gigabit ports
The QSW-M408-2C provides four 10GbE SFP+ ports (with two 10GbE SFP+/RJ45 combo ports) and eight Gigabit 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 10G-SFP-T copper transceiver modules to connect 10GBASE-T/NBASE-T™ devices through RJ45 Category 6, 5 or 5e cabling. The switching capacity of QSW-M408-2C is 96Gbps, guaranteeing the full potential of each port.
Note: The 10GbE SFP+ ports are backward compatible with 1GbE SFP; the RJ45 (copper) combo port supports up to five speeds (10G / 5G / 2.5G / 1G / 100M).

Faster speeds using existing cables with 10GBASE-T & NBASE-T
The QSW-M408-2C 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.
Note: To achieve 10Gb/s speeds, if the distance between the switch and the device is less than 45 meters (148 feet), a Cat 6 cable can be used.
