Four 10GbE combo ports
Choose SFP+ fibre/DAC or multi-speed RJ45 copper at each position.
A desktop managed switch with four selectable 10GbE SFP+/RJ45 combo ports, eight Gigabit RJ45 ports and QNAP Switch System controls.

Each of the four combo positions can operate as SFP+ or multi-speed RJ45, while eight fixed Gigabit RJ45 ports connect standard Ethernet devices. The copper combo interfaces support 10G, 5G, 2.5G, 1G and 100M.
Each combo position represents one selectable SFP+ or RJ45 interface. The supplied information does not list transceivers, DAC cables or Ethernet cables as included, and available copper speed depends on the connected equipment and cabling.
Answers below are based only on the supplied product information for QSW-M408-4C.
It provides 12 network ports: four 10GbE SFP+/RJ45 combo ports and eight 1GbE RJ45 ports.
Each combo position can use either its SFP+ interface or its RJ45 interface, not both as separate simultaneous ports.
The supplied specifications list 10G, 5G, 2.5G, 1G and 100M support.
The supplied description lists LACP, VLAN, QoS, IGMP Snooping, ACL, LLDP, RSTP and flow control.
The supplied specifications list 96Gbps switching capacity and 48Gbps total non-blocking throughput.
The supplied specifications state a 2-year QNAP manufacturer warranty.
