16-port 25GbE SFP28 managed switch

The Qnap QSW-M5216-1T-US is a rackmount network switch built for high-density 25 Gigabit fibre connectivity. It provides sixteen SFP28 ports operating at 25 Gbps and a single 10GbE RJ45 port for management or uplink duties. The unit supports IEEE 802.3by 25 Gigabit Ethernet alongside a full suite of 10G, 5G, 2.5G and legacy Ethernet standards. Management features include VLAN tagging, LACP link aggregation, RSTP and LLDP for automated topology discovery.

Suited for fibre-heavy aggregation layers

This switch fits environments that need sixteen 25 Gbps fibre ports in a 1U form factor with full Layer 2 management. The 32K MAC address table and 9 KB jumbo frame support handle demanding traffic patterns. Buyers who require copper 25G BASE-T ports or Power over Ethernet will need a different platform. Networks built around 10G or 1G copper exclusively will not use the SFP28 density this model provides.

16 x SFP28 + 1 x 10G RJ45 port mix

The defining specification is the port configuration: sixteen 25GbE SFP28 cages plus one 10GbE BASE-T RJ45 interface. That ratio fixes the switch for fibre-rich topologies where a single copper management or uplink port is sufficient. If your design calls for more than one copper 10G port, or any 25G copper ports, this chassis cannot meet the requirement.

Questions about this item

How much power does the 16-port 25GbE SFP28 switch draw when running continuously?

The unit is rated at 35W consumption from a 100-240VAC 50/60 Hz supply, with per-system Power and Status LEDs for monitoring.

What SFP28 transceivers and cables must I provide to use the 16 25GbE ports?

The switch has 16 SFP28 ports that accept 25GbE modules or direct-attach cables; the single RJ45 port handles 10GbE BASE-T connections.

Will my existing 10GbE RJ45 and 1GbE fibre gear link up with this switch?

The RJ45 port supports 10GbE BASE-T and the SFP28 ports accept 10G and 1G fibre modules per IEEE 802.3ae and 802.3z standards.
